Individual identifiers have been removed from the micro-data contained in these files. Nevertheless, under sections 308 (d) and 903 (c) of the Public Health Service Act (42 U.S.C. 242m and 42 U.S.C. 299 a-1), data collected by the Agency for Healthcare Research and Quality (AHRQ) and/or the National Center for Health Statistics (NCHS) may not be used for any purpose other than for the purpose for which they were supplied; any effort to determine the identity of any reported cases is prohibited by law.

Therefore in accordance with the above referenced Federal Statute, it is understood that:

By using these data you signify your agreement to comply with the above stated statutorily based requirements with the knowledge that deliberately making a false statement in any matter within the jurisdiction of any department or agency of the Federal Government violates Title 18 part 1 Chapter 47 Section 1001 and is punishable by a fine of up to $10,000 or up to 5 years in prison.

The Agency for Healthcare Research and Quality requests that users cite AHRQ and the Medical Expenditure Panel Survey as the data source in any publications or research based upon these data.

The Medical Expenditure Panel Survey (MEPS) provides nationally representative estimates of health care use, expenditures, sources of payment, and health insurance coverage for the U.S. civilian non-institutionalized population. The MEPS Household Component (HC) also provides estimates of respondents' health status, demographic and socio-economic characteristics, employment, access to care, and satisfaction with health care. Estimates can be produced for individuals, families, and selected population subgroups. The panel design of the survey, which includes 5 Rounds of interviews covering 2 full calendar years, provides data for examining person level changes in selected variables such as expenditures, health insurance coverage, and health status. Using computer assisted personal interviewing (CAPI) technology, information about each household member is collected, and the survey builds on this information from interview to interview. All data for a sampled household are reported by a single household respondent.

The MEPS-HC was initiated in 1996. Each year a new panel of sample households is selected. Because the data collected are comparable to those from earlier medical expenditure surveys conducted in 1977 and 1987, it is possible to analyze long-term trends. Each annual MEPS-HC sample size is about 15,000 households. Data can be analyzed at either the person or event level. Data must be weighted to produce national estimates.

The set of households selected for each panel of the MEPS HC is a subsample of households participating in the previous year's National Health Interview Survey (NHIS) conducted by the National Center for Health Statistics. The NHIS sampling frame provides a nationally representative sample of the U.S. civilian non-institutionalized population and reflects an oversample of blacks and Hispanics. MEPS oversamples additional policy relevant sub-groups such as Asians and low income households. The linkage of the MEPS to the previous year's NHIS provides additional data for longitudinal analytic purposes.

Upon completion of the household CAPI interview and obtaining permission from the household survey respondents, a sample of medical providers are contacted by telephone to obtain information that household respondents can not accurately provide. This part of the MEPS is called the Medical Provider Component (MPC) and information is collected on dates of visit, diagnosis and procedure codes, charges and payments. The Pharmacy Component (PC), a subcomponent of the MPC, does not collect charges or diagnosis and procedure codes but does collect drug detail information, including National Drug Code (NDC) and medicine name, as well as date filled and sources and amounts of payment. The MPC is not designed to yield national estimates. It is primarily used as an imputation source to supplement/replace household reported expenditure information.

MEPS HC and MPC data are collected under the authority of the Public Health Service Act. Data are collected under contract with Westat, Inc. Data sets and summary statistics are edited and published in accordance with the confidentiality provisions of the Public Health Service Act and the Privacy Act. The National Center for Health statistics (NCHS) provides consultation and technical assistance.

As soon as data collection and editing are completed, the MEPS survey data are released to the public in staged releases of summary reports, micro data files, and tables via the MEPS web site: www.meps.ahrq.gov. Selected data can be analyzed through MEPSnet, an on-line interactive tool designed to give data users the capability to statistically analyze MEPS data in a menu-driven environment.

Additional information on MEPS is available from the MEPS project manager or the MEPS public use data manager at the Center for Financing Access and Cost Trends, Agency for Healthcare Research and Quality, 540 Gaither Road, Rockville, MD 20850 (301-427-1406).

This documentation describes the 2006 full-year population characteristics data file from the Medical Expenditure Panel Survey Household Component (MEPS HC). Released as an ASCII file (with related SAS and SPSS programming statements and data user information) and a SAS transport dataset, this public use file provides information collected on a nationally representative sample of the civilian noninstitutionalized population of the United States for calendar year 2006. The file contains 1120 variables and has a logical record length of 2351 with an additional 2-byte carriage return/line feed at the end of each record.

This file consists of MEPS survey data obtained in Rounds 3, 4, and 5 of Panel 10 and Rounds 1, 2, and 3 of Panel 11, the rounds for the MEPS panels covering calendar year 2006, and contains variables pertaining to survey administration, demographics, employment, health status, disability days, quality of care, patient satisfaction, health insurance and person-level medical care use counts. The 2006 full-year expenditure and income data will be forthcoming.

The following documentation offers a brief overview of the types and levels of data provided, content and structure of the files, and programming information. It contains the following sections:

Both weighted and unweighted frequencies of all the variables included in the 2006 full-year population characteristics data file are provided in the accompanying codebook file.

A database of all MEPS products released to date and a variable locator indicating the major MEPS data items on public use files that have been released to date can be found at the following link on the MEPS Web site: www.meps.ahrq.gov.

This public use dataset contains variables and frequency distributions associated with 34,145 persons who participated in the MEPS Household Component of the Medical Expenditure Panel Survey in 2006. These persons received a positive person-level weight, a family-level weight, or both (some participating persons belonged to families characterized as family-level nonrespondents while some members of participating families were not eligible for a person-level weight). Note that persons who will have a positive family weight but not a positive person weight have been placed on this Public Use File to maintain consistency in terms of file structure with the upcoming Public Use File with expenditure and income data. Those will be the only records without a positive person weight appearing on this file.

Note that unlike some previous MEPS Population Characteristic files, family weights are not included on this release. As indicated above, all persons included on this file that do not have positive person weights will have a positive family weight on the final 2006 Consolidated PUF: HC-105.

These 34,145 persons were part of one of the two MEPS panels for whom data were collected in 2006: Rounds 3, 4, and 5 of Panel 10 or Rounds 1, 2, and 3 of Panel 11. Of these persons, 32,577 were assigned a positive person-level weight. There were 11,780 families receiving a positive family-level weight. The codebook provides both weighted and unweighted frequencies for each variable on the dataset. In conjunction with the person-level weight variable (PERWT06P) provided on this file, data for persons with a positive person-level weight can be used to make estimates for the civilian noninstitutionalized U.S. population for 2006.

This codebook describes an ASCII data set and provides the following programming identifiers for each variable:

In general, variable names reflect the content of the variable, with an eight-character limitation. Edited variables end in an X and are so noted in the variable label. The last two characters in round-specific variables denote the rounds of data collection, Round 3, 4, or 5 of Panel 10 and Round 1, 2, or 3 of Panel 11. Unless otherwise noted, variables that end in "06" represent status as of December 31, 2006.

Variables contained in this delivery were derived either from the questionnaire itself or from the CAPI. The source of each variable is identified in the section of the documentation entitled "Section D. Variable-Source Crosswalk". Sources for each variable are indicated in one of four ways: (1) variables derived from CAPI or assigned in sampling are so indicated; (2) variables derived from complex algorithms associated with re-enumeration are labeled "RE Section"; (3) variables that are collected by one or more specific questions in the instrument have those question numbers listed in the Source column; and (4) variables constructed from multiple questions using complex algorithms are labeled "Constructed."

Users of MEPS data should be aware that the survey collects data for all sample persons who were in the survey target population at any time during the survey period. In other words, a small proportion of individuals in MEPS analytic files are not members of the survey target population (i.e., civilian noninstitutionalized) for the entire survey period. These persons include those who had periods during which they lived in an institution (e.g., nursing home or prison), were in the military, or lived out of the country, as well as those who were born (or adopted) into MEPS sample households or died during the year. They are considered respondents to the survey and are included in MEPS data files with positive person weights, but no data were collected for the periods they were not in-scope and their annual data for variables like health care utilization, expenditures, and insurance coverage reflect only the part of the year they were in-scope for the survey. Persons who are in-scope for only part of the year should not be confused with non-respondents. Sample persons who are classified as non-respondents to one or more rounds of data collection (i.e., initial non-respondents and drop outs over time) are not included in MEPS annual files, and survey weights for full-year respondents are inflated through statistical adjustment procedures to compensate for both full and part-year nonresponse (see section 3.0 for more information). For more details about the identification and analytic considerations regarding sample persons who are in-scope only part of the year, see www.meps.ahrq.gov/about_meps/hc_sample.shtml.

The survey administration variables contain information related to conducting the interview, household and family composition, and person-level and RU-level status codes. Data for the survey administration variables were derived from the sampling process, the CAPI programs, or were computed based on information provided by the respondent in the re-enumeration section of the questionnaire. Most survey administration variables on this file are asked during every round of the MEPS interview. They describe data for Rounds 3/1, 4/2, 5/3 status and status as of December 31, 2006. Variable names ending in "xy" represent variables relevant to Round "x" of Panel 10 or Round "y" of Panel 11. For example, RULETR53 is a variable relevant to Round 5 of Panel 10 or Round 3 of Panel 11, depending on the panel in which the person was included. The variable PANEL indicates the panel in which the person participated.

The December 31, 2006 variables were developed in two ways. Those used in the construction of eligibility, inscope, and the end reference date were based on an exact date. The remaining variables were constructed using data from specific rounds, if available. If data were missing from the target round but were available in another round, data from that other round were used in the variable construction. If no valid data were available during any round of data collection, an appropriate reserved code was assigned.

The definitions of Dwelling Units (DUs) in the MEPS Household Survey are generally consistent with the definitions employed for the National Health Interview Survey (NHIS). The Dwelling Unit ID (DUID) is a five-digit random ID number assigned after the case was sampled for MEPS. A person number (PID) uniquely identifies each person within the DU. The variable DUPERSID is the combination of the variables DUID and PID.

PANEL is a constructed variable used to specify the panel number for the person. PANEL will indicate either Panel 10 or Panel 11 for each person on the file. Panel 10 is the panel that started in 2005, and Panel 11 is the panel that started in 2006.

A Reporting Unit (RU) is a person or group of persons in the sampled DU who are related by blood, marriage, adoption, foster care, or other family association. Each RU was interviewed as a single entity for MEPS. Thus, the RU serves chiefly as a family-based "survey" operations unit rather than an analytic unit. Members of each RU within the DU are identified in the pertinent three rounds by the round-specific variables RULETR31, RULETR42, and RULETR53. End-of-year status (as of December 31, 2006 or the last round they were in the survey) is indicated by the RULETR06 variable. Regardless of the legal status of their association, two persons living together as a "family" unit were treated as a single RU if they chose to be so identified. Examples of different types of RUs are:

Unmarried college students (less than 24 years of age) who usually live in the sampled household but were living away from home and going to school at the time of the Round 3/1 MEPS interview were treated as a RU separate from that of their parents for the purpose of data collection.

The round-specific variables RUSIZE31, RUSIZE42, RUSIZE53, and the end-of-year status variable RUSIZE06 indicate the number of persons in each RU, treating students as single RUs separate from their parents. Thus, students are not included in the RUSIZE count of their parents’ RU. However, for many analytic objectives, the student RUs would be combined with their parents’ RU, treating the combined entity as a single family. Family identifier and size variables are described below and include students with their parents’ RU.

The round-specific variables FAMID31, FAMID42, FAMID53, and the end-of-year status variable FAMID06 identify a family (i.e., persons related to one another by blood, marriage, adoption, foster care, or self-identified as a single unit) for each round and as of December 31, 2006. The FAMID variables differ from the RULETR variables only in that student RUs are combined with their parents’ RU.

One other family identifier, FAMIDYR, is provided on this file. The annualized family ID letter, FAMIDYR, identifies eligible members of the eligible annualized families within a DU. In order to identify a person’s family affiliation, users must create a unique set of FAMID variables by concatenating the DU identifier and the FAMID variable. Instructions for creating family estimates are described in section 3.5.

The round-specific variables FAMSZE31, FAMSZE42, FAMSZE53, and the end-of-year status variable FAMSZE06 indicate the number of persons associated with a single family unit after students are linked to their associated parent RUs for analytical purposes. Family-level analyses should use the FAMSZE variables.

Note that the variables RUSIZE31, RUSIZE42, RUSIZE53, RUSIZE06, FAMSZE31, FAMSZE42, FAMSZE53, and FAMSZE06 exclude persons who are ineligible for data collection (i.e., those where ELGRND31 NE 1, ELGRND42 NE 1, ELGRND53 NE 1 or ELGRND06 NE 1); analysts should exclude ineligible persons in a given round from all family-level analyses for that round.

The round-specific variables RURSLT31, RURSLT42, and RURSLT53 indicate the RU response status for each round. Users should note that the values for RURSLT31 differ from those for RURSLT42 and RURSLT53. The values for RURSLT31 include the following:

Standard or primary RUs are the original RUs from NHIS. A new RU is one created when members of the household leave the primary RU and are followed according to the rules of the survey. A student RU is an unmarried college student (under 24 years of age) who is considered a usual member of the household, but was living away from home while going to school, and was treated as a Reporting Unit (RU) separate from his or her parents’ RU for the purpose of data collection. RUCLAS06 was set based on the RUCLAS values from Rounds 3/1, 4/2, and 5/3. If the person was present in the responding RU in Round 5/3, then RUCLAS06 was set to RUCLAS53. If the person was not present in a responding RU in Round 5/3 but was present in Round 4/2, then RUCLAS06 was set to RUCLAS42. If the person was not present in either Rounds 4/2 or 5/3 but was present in Round 3/1, then RUCLAS06 was set to RUCLAS31. If the person was not linked to a responding RU during any round, then RUCLAS06 was set to -9.

The round-specific variables REGION31, REGION42, REGION53, and the end-of-year status variable REGION06 indicate the Census region for the RU. REGION06 indicates the region for the 2006 portion of Round 5/3. For most analyses, REGION06 should be used.

The round-specific variables MSA31, MSA42, and MSA53 and the end-of-year status variable MSA06 indicate whether or not the RU is found in a Metropolitan Statistical Area and reflect the most recent definitions of metropolitan statistical areas established by Office of Management and Budget (OMB), including the most recent updates. These updates are based on the application of the 2000 Standards for Defining Metropolitan Statistical Areas of OMB to Census Bureau population estimates for July 1, 2004 and July 1, 2005. For MEPS data releases prior to 2004 the MSA variables were coded in compliance with the definition of metropolitan statistical areas based on application of OMB standards to Census 1990 data. MSA31, MSA42, and MSA53 indicate the MSA status at the time of Rounds 3/1, 4/2, and 5/3 interviews. MSA06 indicates the MSA status for the 2006 portion of Round 5/3. For most analyses, analysts should use MSA06 rather than MSA31, MSA42, or MSA53. For MEPS data releases prior to 2004 the MSA variables were coded in compliance with the definition of metropolitan statistical areas based on application of OMB standards to Census 1990 data.

The reference period is the period of time for which data were collected in each round for each person. The reference period dates were determined during the interview for each person by the CAPI program. The round-specific beginning reference period dates are included for each person. These variables include BEGRFM31, BEGRFD31, BEGRFY31, BEGRFM42, BEGRFD42, BEGRFY42, BEGRFM53, BEGRFD53, and BEGRFY53. The reference period for Round 1 for most persons began on January 1, 2006 and ended on the date of the Round 1 interview. For RU members who joined later in Round 1, the beginning Round 1 reference date was the date the person entered the RU. For all subsequent rounds, the reference period for most persons began on the date of the previous round’s interview and ended on the date of the current round’s interview. Persons who joined after the previous round’s interview had their beginning reference date for the round set to the day they joined the RU.

The round-specific ending reference period dates for Rounds 3/1, 4/2, and 5/3 as well as the end-of-year reference period end date variables are also included for each person. These variables include ENDRFM31, ENDRFD31, ENDRFY31, ENDRFM42, ENDRFD42, ENDRFY42, ENDRFM53, ENDRFD53, ENDRFY53, ENDRFM06, ENDRFD06, and ENDRFY06. For most persons in the sample, the date of the round’s interview is the reference period end date. Note that the end date of the reference period for a person is prior to the date of the interview if the person was deceased during the round, left the RU, was institutionalized prior to that round’s interview, or left the RU to join the military.

The round-specific variables REFPRS31, REFPRS42, and REFPRS53 and the end-of-year status variable REFPRS06 identify the reference person for Rounds 3/1, 4/2 and 5/3, and as of December 31, 2006 (or the last round they were in the survey). In general, the reference person is defined as the household member 16 years of age or older who owns or rents the home. If more than one person meets this description, the household respondent identifies one from among them. If the respondent is unable to identify a person fitting this definition, the questionnaire asks for the head of household and this person is then considered the reference person for that RU. This information is collected in the Reenumeration section of the CAPI questionnaire.

The respondent is the person who answered the interview questions for the Reporting Unit (RU). The round-specific variables RESP31, RESP42, and RESP53 and the end-of-year status variable RESP06 identify the respondent for Rounds 3/1, 4/2, and 5/3 and as of December 31, 2006 (or the last round they were in the survey). Only one respondent is identified for each RU. In instances where the interview was completed in more than one session, only the first respondent is indicated.

There are two types of respondents. The respondent can be either an RU member or a non-RU member proxy. The round-specific variables PROXY31, PROXY42, and PROXY53 and the end-of-year status variable PROXY06 identify the type of respondent for Rounds 3/1, 4/2, 5/3 and as of December 31, 2006 (or the last round they were in the survey).

The language of interview variable (INTVLANG) is a summary value of the round-specific RU-level Closing section question, (CL62A), which asks the interviewer to record the language in which the interview was completed. Given the first round that the person was part of the study and the person’s associated RU for that round, INTVLANG is assigned the interview language value reported for the person's RU for the round.

A number of variables describe the various components reflecting each person’s status for each round of data collection. These variables provide information about a person’s inscope status, Keyness status, eligibility status, and disposition status. These variables include: KEYNESS, INSCOP31, INSCOP42, INSCOP53, INSCOP06, INSC1231, INSCOPE, ELGRND31, ELGRND42, ELGRND53, ELGRND06, PSTATS31, PSTATS42, and PSTATS53. These variables are set based on sampling information and responses provided in the Re-enumeration section of the CAPI questionnaire.

Through the Re-enumeration section of the CAPI questionnaire, each member of a RU was classified as "Key" or "Non-Key", "inscope" or "out-of-scope", and "eligible" or "ineligible" for MEPS data collection. To be included in the set of persons used in the derivation of MEPS person-level estimates, a person had to be a member of the civilian noninstitutionalized population for at least one day during 2006. Because a person's eligibility for the survey might have changed since the NHIS interview, a sampling re-enumeration of household membership was conducted at the start of each round’s interview. Only persons who were "inscope" sometime during the year, were "Key", and responded for the full period in which they were inscope were assigned positive person-level weights and thus are to be used in the derivation of person-level national estimates from the MEPS.

Note: If analysts want to subset to infants born during 2006, then newborns should be identified using AGE06X = 0 rather than PSTATSxy = 51.

The round-specific variables INSCOP31, INSCOP42, and INSCOP53 indicate a person’s inscope status for Rounds 3/1, 4/2, and 5/3. INSCOP06, INSC1231, and INSCOPE indicate a person’s inscope status for the portion of Round 5/3 that covers 2006, the person’s inscope status as of 12/31/06, and whether a person was ever inscope during the calendar year 2006. A person was considered as inscope during a round or a referenced time period if he or she was a member of the U.S. civilian, noninstitutionalized population at some time during that round or that time period. The values of these variables taken in conjunction allow one to determine inscope status over time (for example, becoming inscope in the middle of a round, as would be the case for newborns). These variables may contain the following values and corresponding labels:

The term "Keyness" is related to an individual’s chance of being included in MEPS. A person is Key if that person is linked for sampling purposes to the set of NHIS sampled households designated for inclusion in MEPS. Specifically, a Key person was a member of an NHIS household at the time of the NHIS interview or became a member of such a household after being out-of-scope at the time of the NHIS (examples of the latter situation include newborns and persons returning from military service, an institution, or living outside the United States).

A non-Key person is one whose chance of selection for the NHIS (and MEPS) was associated with a household eligible but not sampled for the NHIS and who later became a member of a MEPS Reporting Unit. MEPS data (e.g., utilization and income) were collected for the period of time a non-Key person was part of the sampled unit to provide information for family-level analyses. However, non-Key persons who leave a sample household unaccompanied by a Key, inscope member were not followed for subsequent interviews. Non-Key individuals do not receive sample person-level weights and thus do not contribute to person-level national estimates.

The variable KEYNESS indicates a person’s Keyness status. This variable is not round specific. Instead, it is set at the time the person enters MEPS, and the person’s Keyness status never changes. Once a person is determined to be Key, that person will always be Key.

It should be pointed out that a person might be Key even though not part of the civilian, noninstitutionalized portion of the U.S. population. For example, a person in the military may have been living with his or her civilian spouse and children in a household sampled for NHIS. The person in the military would be considered a Key person for MEPS; however, such a person would not be eligible to receive a person-level sample weight if he or she was never inscope during 2006.

The eligibility of a person for MEPS pertains to whether or not data were to be collected for that person. All of the Key inscope persons of a sampled RU were eligible for data collection. The only non-Key persons eligible for data collection were those who happened to be living in an RU with at least one Key, inscope person. Their eligibility continued only for the time that they were living with at least one such person. The only out-of-scope persons eligible for data collection were those who were living with Key inscope persons, again only for the time they were living with such a person. Only military persons can meet this description (for example, a person on full-time active duty military, living with a spouse who is Key).

A person may be classified as eligible for an entire round or for some part of a round. For persons who are eligible for only part of a round (for example, persons may have been institutionalized during a round), data were collected for the period of time for which that person was classified as eligible. The round-specific variables ELGRND31, ELGRND42, ELGRND53 and the end-of-year status variable ELGRND06 indicate a person’s eligibility status for Rounds 3/1, 4/2 and 5/3 and as of December 31, 2006.

The round-specific variables PSTATS31, PSTATS42, and PSTATS53 indicate a person’s response and eligibility status for each round of interviewing. The PSTATSxy variables indicate the reasons for either continuing or terminating data collection for each person in the MEPS. Using this variable, one could identify persons who moved during the reference period, died, were born, institutionalized or who were in the military. Analysts should note that PSTATS53 provides a summary for all of Round 5/3, including transitions that occurred after 2006.

Since the variables PSTATS31, PSTATS42, and PSTATS53 indicate the reasons for either continuing or terminating data collection for each person in MEPS, these variables can be used to explain the beginning and ending dates for each individual’s reference period of data collection, as well as which sections in the instrument each individual did not receive. By using the information included in the following table, analysts will be able to determine for each individual which sections of the MEPS questionnaire collected data elements for that person.

Some individuals have a reference period that spans an entire round, while other individuals may have data collected only for a portion of the round. When an individual’s reference period does not coincide with the RU reference period, the individual’s start date may be a later date, or the end date may be an earlier date, or both. In addition, some individuals have reference period information coded as "Inapplicable" (e.g., for individuals who were not actually in the household). The information in this table indicates the beginning and ending dates of reference periods for persons with various values of PSTATS31, PSTATS42, and PSTATS53. The actual dates for each individual can be found in the following variables included on this file: BEGRFM31, BEGRFM42, BEGRFM53, BEGRFD31, BEGRFD42, BEGRFD53, BEGRFY31, BEGRFY42, BEGRFY53, ENDRFM31, ENDRFM42, ENDRFM53, ENDRFD31, ENDRFD42, ENDRFD53, ENDRFY31, ENDRFY42, ENDRFY53, ENDRFM06, ENDRFD06, and ENDRFY06.

The table below also describes the section or sections of the questionnaire that were NOT asked for each value of PSTATS31, PSTATS42, and PSTATS53. For example, the condition enumeration (CE) and preventive care (AP) sections have questions that are not asked for deceased persons. The closing section (CL) also contains some questions or question rosters (see CL06A, CL35 through CL37, CL48 through CL50, CL54, CL58, and CL64) that exclude certain persons depending on whether the person died, became institutionalized, or otherwise left the RU; however, no one is considered to have skipped the entire section. Some questions or sections (e.g., health status (HE), employment (RJ, EM, EW)) are skipped if individuals are not within a certain age range. Since the PSTATS variables do not address skip patterns based on age, analysts will need to use the appropriate age variables.

The paper-and-pencil Self-Administered Questionnaire (SAQ) was designed to collect information based on two age categories during Panel 11 Round 2 and Panel 10 Round 4. A person was considered eligible to receive an SAQ if that person did not have a status of deceased or institutionalized, did not move out of the U. S. or to a military facility, was not a non-response at the time of the Round 2 or Round 4 interview date, and was 18 years of age or older. No RU members added in Round 3 or Round 5 were asked to complete an SAQ questionnaire. Because PSTATS variables do not address skip patterns based on age, this questionnaire was not included in the table below. Once again, analysts will need to use the appropriate age variable which in this case would be AGE42X. The documentation for this questionnaire appears in the SAQ section of this document under "Health Status Variables."

Please note that the end reference date shown below for PSTATS53 reflects the Round 5/3 reference period rather than the portion of Round 5/3 that occurred during 2006.

Demographic variables provide information about the demographic characteristics of each person from the MEPS-HC. The characteristics include age, sex, race, ethnicity, educational attainment, marital status, and military service. As noted below, some variables have edited and imputed values. Most demographic variables on this file were asked during every round of the MEPS interview. These variables describe data for Rounds 3, 4, and 5 of Panel 10 (the panel that started in 2005); Rounds 1, 2 and 3 of Panel 11 (the panel that started in 2006); and status as of December 31, 2006. Demographic variables that are round specific are identified by names including numbers "xy", where x and y refer to Round numbers of Panels 10 and 11 respectively. Thus, for example, AGE31X represents the age data relevant to Round 3 of Panel 10 or Round 1 of Panel 11. As mentioned in Section 2.5.1 "Survey Administration" Variables, the variable PANEL indicates the panel from which the data were derived. A value of 10 indicates Panel 10 data and a value of 11 indicates Panel 11 data. The remaining demographic variables on this file are not round specific.

The variables describing demographic status of the person as of December 31, 2006 were developed in two ways. First, the age variable (AGE06X) represents the exact age as of 12/31/06, calculated from date of birth and indicates age status as of 12/31/06. For the remaining December 31^st variables [i.e., related to marital status (MARRY06X, SPOUID06, SPOUIN06), student status (FTSTU06X), and the relationship to reference persons (RFREL06X)], the following algorithm was used: data were taken from Round 5/3 counterpart if non-missing; else, if missing, data were taken from the Round 4/2 counterpart; else from the Round 3/1 counterpart. If no valid data were available during any of these rounds of data collection, the algorithm assigned the missing value (other than -1 "Inapplicable") from the first round that the person was part of the study. When all three rounds were set to –1, a value of –9 "Not Ascertained" was assigned.

Date of birth and age for each RU member were asked or verified during each MEPS interview (DOBMM, DOBYY, AGE31X, AGE42X, AGE53X). If date of birth was available, age was calculated based on the difference between date of birth and date of interview. Inconsistencies between the calculated age and the age reported during the CAPI interview were reviewed and resolved. For purposes of confidentiality, the variables AGE31X, AGE42X, AGE53X and AGE06X were top coded at 85 years.

When date of birth was not provided but age was provided (either from the MEPS interviews or the 2004-2005 NHIS data), the month and year of birth were assigned randomly from among the possible valid options. For any cases still not accounted for, age was imputed using:

For example, a mother’s age is imputed as her child’s age plus 26, where 26 is the mean age difference between MEPS mothers and their children. A wife’s age is imputed as the husband’s age minus 3, where 3 is the mean age difference between MEPS wives and husbands.

Age was imputed in this way for 59 persons on this file. Age was determined for 23 additional persons from data in a later round.

Data on the gender of each RU member (SEX) were initially determined from the 2004 NHIS for Panel 10 and from the 2005 NHIS for Panel 11. The SEX variable was verified and, if necessary, corrected during each MEPS interview. The data for new RU members (persons who were not members of the RU at the time of the NHIS interviews) were also obtained during each MEPS Round. When gender of the RU member was not available from the NHIS interviews and was not ascertained during one of the subsequent MEPS interviews, it was assigned in the following way. The person’s first name was used to assign gender if obvious (no cases were resolved in this way). If the person’s first name provided no indication of gender, then family relationships were reviewed (no cases were resolved this way). If neither of these approaches made it possible to determine the individual’s gender, gender was randomly assigned (1 case was resolved this way).

The race and the ethnic background questions were asked for each RU member during the MEPS interview. If the information was not obtained in Round 1, the questions were asked in subsequent rounds. It should be noted that race/ethnicity questions in the MEPS were revised starting in 2002. Race/ethnicity data from earlier years are not directly comparable. The following table shows the differences:

Values for these variables were obtained based on the following priority order. If available, data collected were used to determine race and ethnicity. If race and/or ethnicity were not reported in the interview, then data obtained from the originally collected NHIS data were used. If still not ascertained, the race, and/or ethnicity were assigned based on relationship to other members of the DU using a priority ordering that gave precedence to blood relatives in the immediate family (this approach was used on 85 persons to set race and 15 persons to set ethnicity).

Starting in 2002, individuals were allowed to choose more than one race and, as a result, three new variables were constructed: RACEBX, RACEAX, and RACEWX. RACEBX identifies individuals as being: 1) Black--- no other race reported, 2) Black--- other race(s) reported, or 3) not black. RACEAX and RACEWX are constructed similarly but apply to Asians and Whites. All race and ethnicity variables reflect the imputations done for RACEX and HISPANX. RACETHNX summarizes both race and ethnicity information in a single variable.

Current marital status was collected and/or updated during every round of the MEPS interview. This information was obtained in RE13 and RE97 and is reported as MARRY31X, MARRY42X, MARRY53X and MARRY06X. Persons under the age of 16 were coded as 6 "Under 16 – Inapplicable". If marital status of a specified round differed from that of the previous round, then the marital status of the specified round was edited to reflect a change during the Round (e.g., married in round, divorced in round, separated in round, or widowed in round).

In instances where there were discrepancies between the marital status of two individuals within a family, other person-level variables were reviewed to determine the edited marital status for each individual. Thus, when one spouse was reported as married and the other spouse reported as widowed, the data were reviewed to determine if one partner should be coded as 8 "Widowed in Round".

Edits were performed to ensure some consistency across rounds. First, a person could not be coded as "Never Married" after previously being coded as any other marital status (e.g., "Widowed"). Second, a person could not be coded as "Under 16 – Inapplicable" after being previously coded as any other marital status. Third, a person could not be coded as "Married in Round" after being coded as "Married" in the round immediately preceding. Fourth, a person could not be coded as an "in Round" code (e.g., "Widowed in Round") in two subsequent rounds. Since marital status can change across rounds and it was not feasible to edit every combination of values across rounds, unlikely sequences for marital status across the round-specific variables do exist.

The person identifier for each individual’s spouse is reported in SPOUID31, SPOUID42, SPOUID53, and SPOUID06. These are the PIDs (within each family) of the person identified as the spouse during Round 3/1, Round 4/2, and Round 5/3 and as of December 31, 2006, respectively. If no spouse was identified in the household, the variable was coded as 995 "No spouse in household". Those with unknown marital status are coded as 996 "Marital Status Unknown". Persons under the age of 16 are coded as 997 "Less than 16 Years Old".

The SPOUIN31, SPOUIN42, SPOUIN53, and SPOUIN06 variables indicate whether a person’s spouse was present in the RU during Round 3/1, Round 4/2, Round 5/3 and as of December 31, 2006 respectively. If the person had no spouse in the household, the value was coded as 2 "Not Married/No Spouse". For persons under the age of 16 the value was coded as 3 "Under 16 – Inapplicable".

The SPOUID and SPOUIN variables were obtained from RE76 and RE77, where the respondent was asked to identify how each pair of persons in the household were related. Analysts should note that this information was collected in a set of questions separate from the questions that asked about marital status. While editing was performed to ensure that SPOUID and SPOUIN are consistent within each round, there was no consistency check between these variables and marital status in a given round. Apparent discrepancies between marital status and spouse information may be due to any of the following causes:

The variables FTSTU31X, FTSTU42X, FTSTU53X and FTSTU06X indicate whether the person was a full-time student at the interview date (or 12/31/06 for FTSTU06X). These variables have valid values for all persons between the ages of 17 - 23 inclusive. When this question was asked during Round 1 of Panel 11, it was based on age as of the 2005 NHIS interview date.

Number of years of education completed is indicated in the variable EDUCYR. Information was obtained from question RE 103. Children who are 5 years of age or older and who never attended school were coded as 0; children under the age of 5 years were coded as -1 "Inapplicable" regardless of whether they attended school. However, among the cases coded as –1 "Inapplicable", there is no distinction between those who were under the age of five and others who were inapplicable, such as persons who may be institutionalized for an entire round. EDUCYR is based on the first round in which the number of years of education is collected for a person. The user should note that EDUCYR is an unedited variable and minimal data cleaning was performed on this variable.

The variable HIDEG, indicating highest degree of education, was obtained from three questions: highest grade completed (RE103), high school diploma (RE104), and highest degree (RE105). Persons under 16 years of age were coded as 8 "Under 16 – Inapplicable". In cases where the response to the highest degree question was "No degree" and the response to the highest grade question was 13 through 17 "1 or More Years of College", the variable HIDEG was coded as 3 "High School Diploma". If highest grade completed was "Refused" or "Don’t Know" for those with a "No Degree" response for the highest degree question, the variable HIDEG was coded as 1 "No Degree". HIDEG is based on the first round in which the highest degree was collected for a person. The user should note that HIDEG is an unedited variable and minimal data cleaning was performed on this variable.

Information on active duty military status was collected during each round of the MEPS interview. Persons currently on full-time active duty status are identified in the variables ACTDTY31, ACTDTY42, and ACTDTY53. Those under 16 years of age were coded as 3 "Under 16 – Inapplicable", and those over the age of 59 were coded as 4 "Over 59 – Inapplicable".

Persons who have been honorably discharged from active duty in the Armed Forces are identified by HONRDC31, HONRDC42, and HONRDC53. Those 16 years of age and under are coded as 3 "16 or Younger – Inapplicable", and those over 16 and currently serving on full-time active duty in the military are coded as 4 "Now Active Duty".

For each Reporting Unit (RU), the person who owns or rents the DU is usually defined as the reference person. For student RUs, the student is defined as the reference person. (For additional information on reference persons, see the documentation on survey administration variables.) The variables RFREL31X, RFREL42X, RFREL53X, and RFREL06X indicate the relationship of each individual to the reference person of the Reporting Unit (RU) in a given round. For the reference person, this variable has the value "Self"; for all other persons in the RU, relationship to the reference person is indicated by codes representing "Husband/Spouse", "Wife/Spouse", "Son", "Daughter", "Female Partner", "Male Partner", etc. A code of 91, meaning "Other Related, Specify", was used to indicate rarely observed relationship descriptions such as "Mother of Partner". If the relationship of an individual to the reference person was not ascertained during the round-specific interview, relationships between other RU members were used, where possible, to assign a relationship to the reference person. If MEPS data from calendar year 2006 were not sufficient to identify the relationship of an individual to the reference person, relationship variables from the 2005 MEPS or NHIS data were used to assign a relationship. In the event that a meaningful value could not be determined or data were missing, the relationship variable was assigned a missing value code.

For 16 cases, where two individuals’ relationship indicated they were spouses, but both had marital status indicating they were not married, their relationship was changed to non-marital partners. In addition, the relationship variables were edited to insure that they did not change across rounds for RUs in which the reference person did not change, with the exception of relationships identified as partner, spouse, or foster relationships.

The variables MOPID31X, MOPID42X, MOPID53X and DAPID31X, DAPID42X DAPID53X are round specific and are used to identify the parents (biological, adopted, or step) of the person represented on that record. MOPID##X contains the person identifier (PID) for each individual’s mother if she lived in the RU in that panel/round of the survey, or a value of –1 (Inapplicable) if she did not. Similarly, DAPID##X contains the person identifier (PID) for each individual’s father if he lived in the RU in that panel/round of the survey, or a value of –1 (Inapplicable) if he did not. MOPID##X and DAPID##X were constructed based on information collected in the relationship grid of the instrument each round at questions RE76 and RE77 and include biological, adopted, and step parents. Foster parents were not included. For persons who were not present in the household during a round, MOPID##X and DAPID##X have values of –1 (Inapplicable).

Edits were performed to ensure that MOPID##X and DAPID##X were consistent with each individual’s age, sex, and other relationships within the family. For instance, the gender of the parent must be consistent with the indicated relationship; mothers are at least 12 years older than the person and no more than 55 years older than the person; fathers are at least 12 years older than the person; each person has no more than one mother and no more than one father; any values set for MOPID##X and DAPID##X were removed from any person identified as a foster child; and the PID for the person’s mother and father are valid PIDs for that person’s RU for the 2006 Full Year File.

Due to the overlapping panel design of the MEPS (Round 3 for Panel 10 overlapped with Round 1 for Panel 11, Round 4 for Panel 10 coincided with Round 2 for Panel 11, and Round 5 for Panel 10 occurred at the same time as Round 3 for Panel 11), data from overlapping rounds have been combined across panels. Thus, any variable ending in "31" reflects data obtained in Round 3 of Panel 10 and Round 1 of Panel 11. Analogous comments apply to variables ending in "42" and "53". Health Status variables whose names end in "06" indicate a full-year measurement.

This data release incorporates information from calendar year 2006. However, health status data obtained in Round 3 of both Panel 10 and Panel 11 are included in variables that have names ending in "31" and "53" respectively. For persons in Panel 10, Round 3 extended from 2005 into 2006. Therefore, for these people, some information from late 2005 is included for variables that have names ending in "31". For persons in Panel 11, Round 3 extended from 2006 into 2007. Therefore, for these people, some information from early 2007 is included for variables that have names ending in "53". Note that for most Panel 10 persons, the Round 5 reference period ends on December 31, 2006; however, the Round 5 interview actually occurs in 2007. Round 5 respondents receive an instruction at the start of the Health Status (HE) section of CAPI to limit information about health status and limitations to the period ending on December 31, 2006. Nevertheless, if respondents forget or ignore this reference period instruction, some information collected in this section in Round 5 (variables ending in "53") might reflect circumstances in early 2007. Further, health status questions asked in the Condition Enumeration (CE), Preventive Care (AP), and Priority Conditions (PC) sections of CAPI in Round 5 do not contain a similar explicit instruction that the reference period ends on December 31, 2006, although this is stated at the start of the overall interview. Hence, in these sections, respondents may also be providing health status information that pertains to 2007.

Health Status variables in this data release can be classified into several conceptually distinct sets:

Perceived health status and ADL and IADL limitations were measured in all rounds. Functional and activity limitations were measured in Rounds 3 and 5 for Panel 10 and Rounds 1 and 3 for Panel 11. Vision, hearing, and children’s health status were measured in Round 4 for Panel 10 and Round 2 for Panel 11. Preventive care and priority conditions were measured in Round 5 of Panel 10 and Round 3 of Panel 11. The self-administered questionnaire was distributed in Round 4 of Panel 10 and Round 2 of Panel 11. The diabetes care supplement was distributed in Round 5 of Panel 10 and Round 3 of Panel 11.

In general, Health Status variables involved the construction of person-level variables based on information collected in the Condition Enumeration and Health Status sections of the questionnaire. Many Health Status questions were initially asked at the family-level to ascertain if anyone in the household had a particular problem or limitation. These were followed up with questions to determine which household member had each problem or limitation. All information ascertained at the family-level has been brought to the person-level for this file. Logical edits were performed in constructing the person-level variables to assure that family-level and person-level values were consistent. Particular attention was given to cases where missing values were reported at the family-level to ensure that appropriate information was carried to the person-level.

Inapplicable cases occurred when a question was never asked because of a skip pattern in the survey (e.g., individuals who were 13 years of age or older were not asked some follow-up verification questions; individuals older than 17 were not asked questions pertaining to children’s health status). Inapplicable cases are coded as -1. In addition, deceased persons were coded as "Inapplicable" (-1).

Perceived health status (RTHLTH31, RTHLTH42, and RTHLTH53) and perceived mental health status (MNHLTH31, MNHLTH42, and MNHLTH53) were collected in the Condition Enumeration section. These questions (CE01 and CE02) asked the respondent to rate each person in the family according to the following categories: excellent, very good, good, fair, and poor.

The Instrumental Activities of Daily Living (IADL) Help or Supervision variables (IADLHP31, IADLHP42, and IADLHP53) were each constructed from a series of three questions administered in the Health Status section of the interview. The initial question (HE01) determined if anyone in the family received help or supervision with IADLs such as using the telephone, paying bills, taking medications, preparing light meals, doing laundry, or going shopping. If the response was "Yes", a follow-up question (HE02) was asked to determine which household member(s) received this help or supervision. For persons under age 13, a final verification question (HE03) was asked to confirm that the IADL help or supervision was the result of an impairment or physical or mental health problem. If the response to the final verification question was "No", IADLHP31, IADLHP42, and IADLHP53 were coded "No" for persons under the age of 13.

If no one in the family was identified as receiving help or supervision with IADLs, all members of the family were coded as receiving no IADL help or supervision. In cases where the response to the family-level question was "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), all persons were coded according to the family-level response. In cases where the response to the family-level question (HE01) was "Yes" but no specific individuals were identified in the follow-up question as having IADL difficulties, all persons were coded as "Don’t Know" (-8).

The Duration of IADL Condition variables (IADL3M31, IADL3M42 and IADL3M53) were constructed from a follow-up question (HE03A) in the Health Status section of the interview. For each person who received IADL help or supervision due to an impairment or physical or mental health problem (IADLHP## is coded "Yes"), HE03A was asked to determine whether the person was expected to need help or supervision with these activities for at least three more months. For persons coded "No" (2), "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9) for IADLHP##, IADL3M## was coded "Inapplicable" (-1).

The Activities of Daily Living (ADL) Help or Supervision variables (ADLHLP31, ADLHLP42, and ADLHLP53) were each constructed in the same manner as the IADL help variables, but using questions HE04-HE06. Coding conventions for missing data were the same as for the IADL variables.

The Duration of ADL Condition variables (ADL3MO31, ADL3MO42 and ADL3MO53) were constructed from a follow-up question (HE06A) in the Health Status section of the interview. For each person who received ADL help or supervision due to an impairment or physical or mental health problem (ADLHLP## is coded "Yes"), HE06A was asked to determine whether the person was expected to need help or supervision with these activities for at least three more months. For persons coded "No" (2), "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9) for ADLHLP##, ADL3MO## was coded "Inapplicable" (-1).

A series of questions pertained to functional limitations, which are defined as difficulty in performing certain specific physical actions. WLKLIM31 and WLKLIM53 were the filter questions, depending on the round. These variables were derived from a question (HE09) that was asked at the family-level: "Does anyone in the family have difficulties walking, climbing stairs, grasping objects, reaching overhead, lifting, bending or stooping, or standing for long periods of time?" If the answer was "No", then all family members were coded as "No" (2) on WLKLIM31 or WLKLIM53. If the answer was "Yes", then the specific persons who had any of these difficulties were identified and coded as "Yes" (1), and remaining family members were coded as "No" (2). If the response to the family-level question was "Don’t Know" (-8), "Refused" (-7), "Not Ascertained" (-9), or "Inapplicable" (-1), then the corresponding missing value code was applied to each family member’s value for WLKLIM31 or WLKLIM53. If the answer to HE09 was "Yes" (1) but no specific individual was named as experiencing such difficulties, then each family member was assigned "Don’t Know" (-8). Deceased persons were assigned a -1 code ("Inapplicable") for WLKLIM31 or WLKLIM53.

For Rounds 3 (Panel 10) and 1 (Panel 11), if WLKLIM31 was coded "Yes" (1) for any family member, a subsequent series of questions was administered. The series of questions for which WLKLIM31 served as a filter is as follows:

This series of questions was asked separately for each person whose response to WLKLIM31 was coded "Yes" (1). The series of questions was not asked for other individual family members whose response to WLKLIM31 was "No" (2). In addition, this series was not asked about family members who were less than 13 years of age, regardless of their status on WLKLIM31. These questions were not asked about deceased family members. In such cases (i.e., WLKLIM31 = 2, or age < 13, or PSTATS31 = 31), each question in the series was coded as "Inapplicable" (-1). Finally, if responses to WLKLIM31 were "Refused" (-7), "Don’t Know" (-8), "Not Ascertained" (-9), or otherwise "Inapplicable" (-1), then each question in this series was coded as "Inapplicable" (-1).

Analysts should note that WLKLIM31 was asked of all household members, regardless of age. For the subsequent series of questions, however, persons less than 13 years old were skipped and coded as "Inapplicable". Therefore, it is possible for someone aged 12 or less to have a code of "Yes" (1) on WLKLIM31, and also to have codes of "Inapplicable" on the subsequent series of questions.

For Rounds 5 (Panel 10) and 3 (Panel 11), the corresponding filter question was WLKLIM53.

Editing conventions were the same for this "53" series of variables as they were for the corresponding "31" series described above.

The variables indicating use of assistive technology (AIDHLP31 and AIDHLP53, from question HE07) and social/recreational limitations (SOCLIM31 and SOCLIM53, from question HE22) were collected initially at the family-level. If there was a "Yes" (1) response to the family-level question, a second question identified the specific individual(s) to whom the "Yes" response pertained. Each individual identified as having the difficulty was coded "Yes" (1) for the appropriate variable; all remaining family members were coded "No". If the family-level response was "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" but no specific individual was identified as having difficulty, all family members were coded as "Don’t Know" (-8).

The variables indicating any limitation in work, housework, or school (ACTLIM31 and ACTLIM53) were constructed using questions HE19-HE20. Specifically, information was collected initially at the family-level. If there was a "Yes" (1) response to the family-level question (HE19), a second question (HE20) identified the specific individual(s) to whom the "Yes" (1) response pertained. Each individual identified as having a limitation was coded "Yes" (1) for the appropriate variable; all remaining family members were coded "No" (2). If the family-level response was "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" (1) but no specific individual was identified as having difficulty, all family members were coded as "Don’t Know" (-8). Persons less than five years old were coded as "Inapplicable" (-1) on ACTLIM31 and ACTLIM53.

For Round 3 (Panel 10) or Round 1 (Panel 11), if ACTLIM31 was "Yes" (1) and the person was 5 years of age or older, a follow-up question (HE20A) was asked to identify the specific limitation or limitations for each person. These included working at a job (WRKLIM31), doing housework (HSELIM31), or going to school (SCHLIM31). Respondents could answer "Yes" (1) or "No" (2) to each activity; thus a person could report limitations in multiple activities. WRKLIM31, HSELIM31, and SCHLIM31 have values of "Yes" (1) or "No" (2) only if ACTLIM31 was "Yes" (1); each variable was coded as "Inapplicable" (-1) if ACTLIM31 was "No" (2). When ACTLIM31 was "Refused" (-7), these variables were all coded as "Refused" (-7); when ACTLIM31 was "Don’t Know" (-8), these variables were all coded as "Don’t Know" (-8); and when ACTLIM31 was "Not Ascertained" (-9), these variables were all coded as "Not Ascertained" (-9). If a person was under 5 years old or was deceased, WRKLIM31, HSELIM31, and SCHLIM31 were each coded as "Inapplicable" (-1).

An additional question (UNABLE31) was asked if the person was completely unable to work at a job, do housework, or go to school. Those respondents who were coded "No" (2), "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9) on ACTLIM31, were under 5 years of age, or were deceased were coded as "Inapplicable" (-1) on UNABLE31. UNABLE31 was asked once for whichever set of WRKLIM31, HSELIM31, and SCHLIM31 the respondent had limitations; if a respondent was limited in more than one of these three activities, UNABLE31 did not specify if the respondent was completely unable to perform all of them, or only some of them.

For Rounds 5 (Panel 10) or 3 (Panel 11) corresponding variables were ACTLIM53, WRKLIM53, HSELIM53, SCHLIM53, and UNABLE53. Editing conventions were the same as those described above.

The variables indicating any cognitive limitation (COGLIM31 or COGLIM53, depending on the round) were collected at the family-level as a three-part question (HE24-01 to HE24-03), asking if any of the adults in the family (1) experience confusion or memory loss, (2) have problems making decisions, or (3) require supervision for their own safety. If a "Yes" response was obtained to any item, the persons affected were identified in HE25, and COGLIM31 or COGLIM53 was coded as "Yes" (1). Remaining family members not identified were coded as "No" (2) for COGLIM31 or COGLIM53.

If responses to HE24-01 through HE24-03 were all "No", or if two of three were "No" (2) and the remaining was "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), all family members were coded as "No" (2). If responses to the three questions were combinations of "Don’t Know" (-8), "Refused" (-7), and missing, all persons were coded as "Don’t Know" (-8). If the response to any of the three questions was "Yes" (1) but no individual was identified in HE25, all persons were coded as "Don’t Know" (-8).

The cognitive limitations variables (COGLIM31 and COGLIM53) reflect whether any of the three component questions is "Yes" (1). Respondents with one, two, or three specific cognitive limitations cannot be distinguished. In addition, because the question asked specifically about adult family members, all persons less than 18 years of age are coded as "Inapplicable" (-1) on this question.

A series of questions (HE26 to HE32) provides information on visual impairment. These questions were asked of all household members, regardless of age. Deceased respondents were coded as "Inapplicable" (-1).

WRGLAS42 indicates whether a person wears eyeglasses or contact lenses. This variable was based on two questions, HE26 and HE27. The initial question (HE26) determined if anyone in the family wore eyeglasses or contact lenses. If the response was "Yes" (1), a follow-up question (HE27) was asked to determine which household member(s) wore eyeglasses or contact lenses. If the family-level response was "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" (1) but no specific individual was identified as wearing glasses or contact lenses, all family members were coded as "Don’t Know" (-8).

SEEDIF42 indicates whether anyone in the family had difficulty seeing (with glasses or contacts, if used). This variable was based on two questions, HE28 and HE29. The initial question (HE28) determined if anyone in the family had difficulty seeing. If the response was "Yes" (1), a follow-up question (HE29) was asked to determine which household member(s) had a visual impairment. If the family-level response was "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" (1) but no specific individual was identified as having difficulty seeing, all family members were coded as "Don’t Know" (-8).

Three subsequent questions were asked only of individuals who had difficulty seeing (i.e., SEEDIF42 was "Yes" (1)). Persons with no visual impairment were coded as "Inapplicable" (-1) for these questions, as were persons with "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9) responses to SEEDIF42. The three subsequent questions are summarized in the three subsequent variables. BLIND42 determined if a person with difficulty seeing was blind. For persons who were not blind (BLIND42 was "No" (2)), READNW42 asked whether the person could see well enough to read ordinary newspaper print (with glasses or contacts, if used); persons who were blind were not asked this question and were coded "Inapplicable" (-1). For persons who could not read ordinary newspaper print (READNW42 was "No" (2)), RECPEP42 asked if the person could see well enough to recognize familiar people standing two or three feet away. Persons who were blind or who could read newsprint were not asked this question and were coded "Inapplicable" (-1).

VISION42 summarizes the pattern of responses to the set of visual impairment questions. Codes for VISION42 are as follows:

A series of questions (HE33 to HE39) provides information on hearing impairment. These questions were asked of all household members, regardless of age. Deceased respondents were coded "Inapplicable" (-1).

HEARAD42 indicates whether a person wears a hearing aid. This variable was based on two questions, HE33 and HE34. The initial question (HE33) determined if anyone in the family wore a hearing aid. If the response was "Yes", a follow-up question (HE34) was asked to determine which household member(s) wore a hearing aid. If the family-level response was "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" but no specific individual was identified as wearing a hearing aid, all family members were coded as "Don’t Know" (-8).

HEARDI42 indicates whether a person had difficulty hearing (with a hearing aid, if used). This variable is based on two questions, HE35 and HE36. The initial question (HE35) determined if anyone in the family had difficulty hearing. If the response was "Yes", a follow-up question (HE36) was asked to determine which household member had an aural impairment. If the family-level response was "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9), all persons were coded with the family-level response. In cases where the family-level response was "Yes" but no specific individual was identified as having difficulty hearing, all family members were coded as "Don’t Know" (-8).

Three subsequent questions were asked only of individuals who had difficulty hearing (i.e., HEARDI42 was "Yes" (1)). Persons with no hearing impairment were coded as "Inapplicable" (-1) for these questions, as were persons with "Don’t Know" (-8), "Refused" (-7), or "Not Ascertained" (-9) responses to HEARDI42. The three subsequent questions are summarized in the three subsequent variables. DEAF42 determined if a person with difficulty hearing was deaf. For persons who were not deaf (DEAF42 was "No" (2)), HEARMO42 asked whether the person could hear well enough to hear most of the things people say (with a hearing aid, if used); persons who were deaf were not asked this question and were coded as "Inapplicable" (-1). For persons who could not hear most things people say (HEARMO42 was "No" (2)), HEARSM42 asked if the person could hear well enough to hear some of the things that people say. Persons who were deaf or who could hear most conversation were not asked this question and were coded as "Inapplicable" (-1).

HEARNG42 summarizes the pattern of responses to the set of hearing impairment questions. Codes for HEARNG42 are as follows:

ANYLIM06 summarizes whether a person has any ADL, IADL, activity, functional, or sensory limitations in any of the pertinent rounds. This variable was derived based on data from Rounds 3, 4, and 5 (Panel 10) or Rounds 1, 2, and 3 (Panel 11). ANYLIM06 was built using the component variables IADLHP31, IADLHP42, IADLHP53, ADLHLP31, ADLHLP42, ADLHLP53, WLKLIM31, WLKLIM42, WLKLIM53, ACTLIM31, ACTLIM53, SEEDIF42, and HEARDI42. (The latter two variables, discussed above, indicate any visual or hearing impairment, respectively.) If any of these components was coded "Yes", then ANYLIM06 was coded "Yes" (1). If all components were coded "No", then ANYLIM06 were coded "No" (2). If all the components were "Inapplicable" (-1), then ANYLIM06 was coded as "Inapplicable" (-1). If all the components had missing value codes (i.e., -7, -8, -9, or –1), ANYLIM06 was coded as "Not Ascertained" (-9). If some components were "No" and others had missing value codes, ANYLIM06 was coded as "Not Ascertained" (-9). The exception to this latter rule was for children younger than five years old, who were not asked questions that are the basis for ACTLIM31 or ACTLIM53; for these respondents, if all other components were "No", then ANYLIM06 was coded as "No" (2). The variable label for ANYLIM06 departs slightly from conventions. Typically, variables that end in "06" refer only to 2006. However, some of the variables used to construct ANYLIM06 were assessed in 2007, so some information from early 2007 is incorporated into this variable.

Starting in 2001, a Child Health and Preventive Care section was added to Rounds 2 and 4 of MEPS, and it contains questions that had been in the 2000 Parent Administered Questionnaire (PAQ), selected children’s questions that had been asked in previous years, and additional child preventive care questions. Questions were asked about each child (under the age of 18 excluding deceased children) in the applicable age subgroups to which they pertained. For the Child Supplement variables, a code of "Inapplicable" (-1) was assigned if a person was deceased, was not in the appropriate Round 2 or 4, or was not in the applicable age subgroup as of the interview date. This public use dataset contains variables and frequency distributions from the Child Health and Preventive Care Section associated with 10,017 children who were eligible for the Child Health and Preventive Care Section. Children were eligible for this section when PSTATS42 was not equal to 31 (Deceased) and 0 <= AGE42X <= 17. Of these children, 9,630 were assigned a positive person-level weight for 2006 (PERWT06P > 0). Cases not eligible for the Child Health and Preventive Care Section should be excluded from estimates made with the Child Health and Preventive Care Section. Questions in this section that previously had been in the Parent Administered Questionnaire in 2000 may produce slightly different estimates starting in 2001 due to the change in mode from a self-administered parent questionnaire in 2000 to an interviewer administered questionnaire starting in 2001.

Several questions from the General Health Subscale of the Child Health Questionnaire were asked about all children ages 0 through 17. The questions asked starting in 2001 are slightly different from the questions asked in previous years. A key reference for the Child Health Questionnaire is:

Four questions asked for ratings of the child’s health on a 5-point scale, ranging from "Definitely True" (1) to "Definitely False" (5). These questions were:

The Children with Special Health Care Needs (CSHCN) Screener instrument was developed through a national collaborative process as part of the Child and Adolescent Health Measurement Initiative (CAHMI) under the coordination by the Foundation for Accountability. A key reference for this screener instrument is:

These questions are asked about children ages 0 –17 and had been asked in the 2000 PAQ. In general, the CSHCN screener identifies children with activity limitation or need or use of more health care or other services than is usual for most children of the same age. When a response to a gate question was set to "No" (2), "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), follow-up variables based on the gate question were coded as "Inapplicable" (-1).

The variable CSHCN42 identifies children with special health care needs, and was created using the CSHCN screener questions according to the specifications in the reference above. The CSHCN screener questions consist of a series of question-sequences about the following five health consequences: the need or use of medicines prescribed by a doctor; the need or use of more medical care, mental health, or education services than is usual for most children; being limited or prevented in doing things most children can do; the need or use of special therapy such as physical, occupational, or speech therapy; and the need or use of treatment or counseling for emotional, developmental, or behavioral problems. Parents who responded "yes" to any of the "initial" questions in the five question-sequences were then asked to respond to up to two follow-up questions about whether the health consequence was attributable to a medical, behavioral, or other health condition lasting or expected to last at least 12 months. Children with positive responses to at least one of the five health consequences along with all of the follow-up questions were identified as having a Special Health Care Need. Children with a "no" response for at least one question for each of the five question-sequences were considered NOT to have a Special Health Care Need. Those children whose "special health care need" status could not be determined (due to missing data for any of the questions) were coded as "Unknown". More information about the CSHCN screener questions can be obtained from (www.facct.org).

These questions inquired about possible child behavioral problems and were asked in previous years. Respondents were asked to rate on a scale from 0 to 4, where "0" indicates "No Problem" and "4" indicates "A Very Big Problem", how much of a problem the child has with thirteen specified activities. A key reference for the Columbia Impairment Scale is:

Certain questions in this series were coded to "Asked, but Inapplicable" (99) when the question was not applicable for a specific child. For example, if a child’s mother was deceased, a question about how much of a problem a child has getting along with his/her mother would be set to "Asked, but Inapplicable" (99). Similarly, the question about problems getting along with siblings would be set to "Asked, but Inapplicable" (99) for children with no siblings. Variables in this set include:

The health care quality measures were taken from the health plan version of CAHPS®, an AHRQ sponsored family of survey instruments designed to measure quality of care from the consumer’s perspective and had been asked in the 2000 PAQ. While there have been several changes in these questions since 2000 that are discussed in the specific year’s file documentation, there were no changes to these questions from 2005 to 2006. All of the CAHPS® variables refer to events experienced in the last 12 months. The variables included from the CAHPS® are:

A series of questions was asked about amounts and types of preventive care a child may receive when going to see a doctor or other health provider. Questions are asked of children of different age groups depending on the nature of the questions. When a response to a gate question was set to "No" (2), "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), follow-up variables based on the gate question were coded as "Inapplicable" (-1). Variables in this set include:

Due to confidentiality concerns and restrictions, the variables HGTFT42, HGTIN42, WGTLB42 and WGTOZ42, will not be included on the Full-Year 2006 file. Instead, a Body Mass Index (BMI) variable, CHBMIX42, was calculated and included for children 6-17 years old. Due to a high percentage of missing height data for children ages 5 and under (27%), these children were given a "-1 Inapplicable" code for the variable CHBMIX42. CHBMIX42 is included in the 2006 file and on the above list. Please note: analysts can have access to the height and weight variables and/or construct a BMI variable of their own through the MEPS Data Center. To access information on the MEPS Data Center including an application, please go to the following Web address: www.meps.ahrq.gov/data_stats/onsite_datacenter.jsp.

Note that for FY 2006, child height and weight were not top-coded prior to the construction of the preliminary data set. Where height in feet was > 0 and height in inches was missing, the mid-point value for height in inches (6 inches) was assigned to HGTIN42 for use in the calculation of the child BMI. Where height in feet was 0 and height in inches was missing, the preliminary child BMI was set to "Not Ascertained" (-9).

For cases where weight in pounds was between 1 and 20 and weight in ounces was missing (WGTOZ42 in (-7,-8,-9)), the mid-point value for weight in ounces (8 ounces) was assigned to WGTOZ42 for use in the calculation of the child BMI. Where weight in pounds was 0 and weight in ounces was missing, the preliminary child BMI was set to "Not Ascertained" (-9).

This use of the mid-points for inches and ounces ensures that children who have feet but not inches in height and/or pounds but not ounces in weight are included in the BMI calculation.

As indicated in step 2 above a preliminary SAS data set containing height, weight, sex and age data for children 6-17 years old in FY 2006 was created. Two SAS programs were downloaded from the Centers for Disease Control and Prevention Web site for the purpose of calculating the BMI for children (step 3). These programs used the preliminary data set of children to generate a preliminary child BMI based on the 2000 CDC growth charts (www.cdc.gov/growthcharts/). These programs used the following formula to calculate the preliminary BMI for children:

Note that weight in pounds and ounces was converted to weight in kilograms in the preliminary data set. Similarly, height in feet and inches was converted to height in centimeters in the preliminary data set.

As indicated in step 4 above, the child BMI variable CHBMIX42 was calculated using this preliminary BMI from step 3. Deceased persons, persons > 17 years old, and children younger than 6 years old were set to Inapplicable (-1) for CHBMIX42. Children 6-17 years old with a missing value for height in feet (HGTFT42 is "Refused" (–7), "Don’t Know" (-8), or "Not Ascertained" (-9)) and/or weight in pounds (WGTLB42 is "Refused" (–7), "Don’t Know" (-8), or "Not Ascertained" (-9)) were set to Not Ascertained (-9) for CHBMIX42. Children whose height in feet was 0 and height in inches was missing (HGTIN42 is "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9)) were set to "Not Ascertained" (-9) for CHBMIX42. Children whose weight in pounds was 0 and weight in ounces was missing (WGTOZ42 is "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9)) were set to "Not Ascertained" (-9) for CHBMIX42. All other children 6-17 years old have a calculated BMI for FY 2006.

For each person, excluding deceased persons, a series of questions was asked primarily about the receipt of preventive care or screening examinations. Questions varied in the applicable age or gender subgroups to which they pertained. The list of variables in this series, along with their applicable subgroup is as follows:

For each of the variables above, a code of "Inapplicable" (-1) was assigned if the person was deceased or if the person did not belong to the applicable subgroups.

Due to confidentiality concerns and restrictions, the variables HGHTFT53, HGHTIN53, WEIGHT53 and WGTEST53, will not be included on the Full-Year 2006 file. Instead, a Body Mass Index (BMI) variable, BMINDX53, was calculated for adults 18 years of age or older. BMINDX53 is included in the 2006 file and on the above list. Please note: analysts can have access to the height and weight variables and/or construct a BMI variable of their own through the MEPS Data Center. To access information on the MEPS Data Center including an application, please go to the following Web address: meps.ahrq.gov/data_stats/onsite_datacenter.jsp.

The following formula used to calculate the BMI for adults was taken from the Centers for Disease Control and Prevention (www.cdc.gov/) Web site:

For FY 2006, adult height and weight were not top- or bottom-coded prior to the construction of the adult BMI.

The building block variable ADHGTIN was calculated as [(HGHTFT53 * 12) + (HGHTIN53)] to indicate total adult height in inches, step 2. Note that ADHGTIN was created for programming efficiency only and is not included in this data release. For cases where height in feet was > 0 (HGHTFT53 > 0) and height in inches was missing (HGHTIN53 in (-7, -8, -9)), the mid-point value for height in inches (6 inches) was used in the calculation of total height in inches [ADHGTIN = (HGHTFT53 * 12) + 6]. This use of the mid-point for inches ensures that adults who have feet but not inches in height are included in the BMI calculation. ADHGTIN was set to Not Ascertained (-9) for all cases where adult height in feet was "Refused", "Don’t Know", or "Not Ascertained" (HGHTFT53 in (-7, -8, -9)). Deceased persons and persons whose age was less than 18 years old were set to Inapplicable (-1) for ADHGTIN.

The temporary variable MIDWGT was calculated to indicate the mid-point value of person’s estimate of weight (WGTEST53), step 3. The value 400, rather than a mid-point, was assigned to MIDWGT where estimate of weight was "400 pounds or more" (WGTEST53 = 18). Note that MIDWGT was created for programming efficiency only and is not included in this data release.

The adult BMI variable BMINDX53 was calculated (step 4) using the building block variable ADHGTIN and adult weight in pounds (WEIGHT53) as follows:

For adults whose weight in pounds was "Don’t Know" (WEIGHT53 = -8) and whose estimate of weight was > 0 (WGTEST53 between 1 and 18), MIDWGT was used in the calculation of BMINDX53:

BMINDX53 was set to "Not Ascertained" (-9) for adults whose weight in pounds was "Refused" or "Not Ascertained" (WEIGHT53 in (-7, -9)). BMINDX53 was set to "Not Ascertained" (-9) for adults whose weight in pounds was "Don’t Know" (-8) and whose estimate of weight was "Refused", "Don’t Know", or "Not Ascertained" (WGTEST53 in (-7, -8, -9)). BMINDX53 was set to "Not Ascertained" (-9) for adults whose total height in inches was "Not Ascertained" (ADHGTIN = -9). Deceased persons and persons whose age was less than 18 years old were set to "Inapplicable" (-1) for BMINDX53.

For each person, excluding deceased persons, questions from the supplemental Priority Condition (PC) section were asked about the existence of select priority conditions. Questions varied in the applicable age subgroups to which they pertained.

Note that if edited age is within range for the variable to be set, but the source data are missing because person’s age in CAPI is not within range, the constructed variable is set to "Not Ascertained" (-9).

These conditions were selected because (1) they are relatively prevalent and (2) generally accepted standards for appropriate clinical care have been developed. As part of AHRQ’s focus on the quality of health care, this series of questions obtained information on the receipt of tests or procedures appropriate for each condition. This information thus supplements other information on medical conditions that is gathered in other parts of the interview.

It should be noted that unlike condition information collected elsewhere in the MEPS, conditions identified in the priority care section of the instrument were not added to the condition roster. In addition, chronic conditions asked about in this section were asked in the context of "has person ever been told by a doctor or other health care professional that they have (condition)?", rather than the standard reference period. Thus, there may be legitimate inconsistencies between items in this section and conditions recorded for a person on the condition file.

Editing of these variables focused on checking that skip patterns were consistent.

Questions about sore throats were asked only of persons under age 18. Consequently, persons 18 years of age or older were coded as "Inapplicable" (-1) on these questions. SRTHRT53 indicates whether each person had a sore throat serious enough to cause the person to call a doctor or other health professional during the last 12 months. Those who said "Yes" (1) to SRTHRT53 were asked whether the person who contacted a doctor or other health professional in the last 12 months did so primarily due to a sore throat or some other symptoms (THSYMP53). For those who said "Sore Throat" (1) to THSYMP53, a follow-up question was asked which indicates whether the person actually saw the doctor or other health professional for the sore throat (DRTHRT53). THANTB53 indicates whether the doctor or other health provider prescribed antibiotics for the sore throat. Those who said "Yes" (1) to THANTB53 were asked whether the person received a throat swab before receiving the antibiotics (THSWAB53). For those who answered "No" (2), "Refused" (-7), or "Don't Know" (-8), a follow-up question, THSYMF53, was asked which indicates whether other persons in the household had similar symptoms around the same time. If THSYMF53 was answered "Yes" (1), the person was asked whether a doctor or other health professional gave these family members a throat swab (THSWBF53) and whether a doctor or health professional prescribed antibiotics for these family members (THANTF53).

DIABDX53 indicates whether each person had ever been diagnosed with diabetes (excluding gestational diabetes). Each person who said they had received a diagnosis of diabetes was asked to complete a special self-administered questionnaire. The documentation for this questionnaire appears in the Diabetes Care Survey (DCS) section of the documentation.

(Please note: the follow-up asthma questions were revised for 2003). ASTHDX53 indicates whether a respondent had ever been diagnosed with asthma. Those who said "Yes" were asked additional questions. ASSTIL53 asked if the person still had asthma. ASATAK53 asked whether the person had experienced an episode of asthma or an asthma attack in the past 12 months. Persons who said "Yes" for either ASSTIL53 or ASATAK53 were asked further follow-up questions regarding asthma medication used for quick relief (ASACUT53), preventive medicine (ASPREV53), and peak flow meters (ASPKFL53). ASACUT53 asked whether the person had used the kind of prescription inhaler that you breathe in through your mouth that gives quick relief from asthma symptoms. Those who said "Yes" to ASACUT53 were asked whether they had used more than three canisters of this type of inhaler in the past 3 months (ASMRCN53). ASPREV53 asked whether the person had ever taken the preventive kind of asthma medicine used every day to protect the lungs and prevent attacks, including both oral medicine and inhalers. Those who said "Yes" to ASPREV53 were asked whether they now took this kind of medication daily or almost daily (ASDALY53). ASPKFL53 indicates whether the person with asthma had a peak flow meter at home. Those persons who said "Yes" to ASPKFL53 were asked if they ever used the peak flow meter (ASEVFL53). Those persons who said "Yes" to ASEVFL53 (those persons who had used the peak flow meter) were asked when they last used the peak flow meter (ASWNFL53). Those who said "No" (2) (or "Refused" (-7) or "Don’t Know" (-8)) to ASTHDX53 were not asked ASSTIL53, ASATAK53, ASACUT53, ASMRCN53, ASPREV53, ASDAYLY53, ASPKFL53, ASEVFL53 and ASWNFL53; these respondents have been assigned a code of "Inapplicable" (-1) for these variables. Those who said "No" (2) (or "Refused" (-7) or "Don’t Know" (-8)) to ASSTIL53 and ASATAK53 were not asked ASACUT53, ASMRCN53, ASPREV53, ASDAYLY53, ASPKFL53, ASEVFL53 and ASWNFL53; these respondents have been assigned a code of "Inapplicable" (-1) for these variables.

Questions about high blood pressure (hypertension) were asked only of respondents aged 18 or older. Consequently, persons aged 17 or younger were coded as "Inapplicable" (-1) on these variables. HIBPDX53 ascertained whether the person had ever been diagnosed as having high blood pressure (other than during pregnancy). Those who had received this diagnosis were also asked if they had been told on two or more different visits that they had high blood pressure (BPMLDX53).

All respondents older than 17 (regardless of hypertension diagnosis) were also asked how long it had been since they had their blood pressure checked by a doctor, nurse, or other health professional (BPCHEK53). If the response was within the past year or two years, the number of months since the last blood pressure check was ascertained (BPMONT53). If the response to BPCHEK53 was longer than 2 years, BPMONT53 was not asked and was coded as "Inapplicable" (-1).

New questions about high cholesterol were asked of respondents aged 18 or older. Consequently, persons aged 17 or younger were coded as "Inapplicable" (-1) on these variables. CHOLDX53 ascertained whether the person had ever been diagnosed as having high cholesterol. Those who had received this diagnosis were also asked at what age this diagnosis occurred (CHLAGE53). Note that, like the AGE##X variables, CHLAGE53 was top coded to 85 years of age for confidentiality purposes. Persons who were diagnosed over the age of 85 have CHLAGE53 set to 85.

The next series of questions concerned ischemic heart disease. The questions were asked only of respondents aged 18 or older. Consequently, persons aged 17 or younger were coded as "Inapplicable" (-1) on all the variables in this set.

In addition, all persons aged 18 or older were asked the following three questions about diet, exercise and use of aspirin:

If the answer to ASPRIN53 was "No", or if the response was "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), a follow-up question asked if the person had a health problem that made taking aspirin unsafe (NOASPR53). If the answer to NOASPR53 was "Yes" (1), the person was asked if this problem was stomach-related or something else (STOMCH53).

Those who answered "No" to NOASPR53 were coded as "Inapplicable" (-1) for STOMCH53. Those who answered "Yes" to ASPRIN53 were coded as "Inapplicable"
(-1) on NOASPR53 and on STOMCH53.

EMPHDX53 asked if the person (aged 18 or older) had ever been diagnosed with emphysema. Persons aged 17 or younger were coded as "Inapplicable" (-1).

JTPAIN53 asked if the person (aged 18 or older) had experienced pain, swelling, or stiffness around a joint in the last 12 months. Persons aged 17 or younger were coded as "Inapplicable" (-1). This question is not intended to be used as an indicator of a diagnosis of arthritis.

ARTHDX53 asked if the person (age 18 or older) had ever been diagnosed with arthritis. Persons aged 17 or younger were coded as "Inapplicable" (-1). If the person said "Yes" (1) to ARTHDX53, a follow-up question, ARTHTX53, was asked which indicates whether the person is currently being treated for arthritis.

The 2006 Self-Administered Questionnaire (SAQ), a paper-and-pencil questionnaire, was fielded during Panel 10 Round 4 and Panel 11 Round 2 of the 2006 Medical Expenditure Panel Survey (MEPS). The survey was designed to collect a variety of health status and health care quality measures of adults. All adults age 18 and older as of the Round 2 or 4 interview date (AGE42X >= 18) in MEPS households were asked to complete a SAQ. The questionnaires were administered in late 2006 and early 2007.

The variable SAQELIG indicates the person’s eligibility status for the SAQ. SAQELIG was used to construct the variables based on the SAQ data. SAQELIG was coded "0" (Not Eligible For SAQ) if there was no record for person in the round, if the person was deceased, institutionalized, moved out of the US, moved to a military facility, or the person’s disposition status was inapplicable, or if the person was less than 18 years old. SAQELIG was coded "1" (Eligible For SAQ and Has SAQ Data) if a SAQ record existed for the person in Round 2 (for Panel 11) or Round 4 (for Panel 10). SAQELIG was coded "2" (Eligible For SAQ, But No SAQ Data) if no SAQ record existed for the person in the round.

If a respondent was unable to respond to the SAQ, the questionnaire was completed by a proxy, as indicated by the variable ADPRX42 (ADPRX42 > 0). For the SAQ variables, a code of "Inapplicable" (-1) was assigned if a person was not eligible or was eligible but no data existed based on SAQELIG (SAQELIG was coded "0" or "2"). If a person was not assigned a positive SAQ weight, all SAQ variables, with the exception of SAQELIG, were coded "Inapplicable" (-1). When a response to a gate question answer was set to "No" (2), follow-up variables based on the gate question were coded as "Inapplicable"
(-1). When a gate question answer was set to "Refused" (-7), "Don’t Know" (-8), or "Not Ascertained" (-9), follow-up variable answers were left as reported. A special weight variable (SAQWT06P) has been designed to be used with the SAQ for persons who were age 18 and older at the interview date. This weight adjusts for SAQ non-response and weights to the US civilian noninstitutionalized population (see Section 3.0 of the documentation for details). The variables created from the SAQ begin with "AD".

The language in which the SAQ was completed is indicated by the variable ADLANG42. If the English version of the SAQ was completed, ADLANG42 was coded "1" (English Version SAQ Was Administered). If the Spanish version of the SAQ was completed, or if the English version was translated into Spanish, ADLANG42 was coded "2" (Spanish Version SAQ Was Administered). If the language in which the SAQ was administered was not ascertained, ADLANG42 was coded "-9" (Not Ascertained).

The month, day and year the SAQ was completed are indicated by the variables ADCMPM42, ADCMPD42 and ADCMPY42, respectively.

The health care quality measures in the SAQ were taken from the health plan version of CAHPS®, an AHRQ-sponsored family of survey instruments designed to measure quality of care from the consumer’s perspective. All of the variables refer to events experienced in the last 12 months and were asked of adults age 18 and older. The variables included from the CAHPS® are:

The SAQ contained three measures of health status, the Short-Form 12 Version 2 (SF-12v2 (r), a registered trademark), the Kessler Index (K6) of non-specific psychological distress, and the Patient Health Questionnaire (PHQ-2). Key references for these three measures are:

In analyzing data from the SF-12v2, the standard approach is to form two summary scores, based on responses to these questions. The underlying conception is that overall health is composed of a physical component and a mental component. The Physical Component Summary (PCS) weights more heavily responses to the first five SF-12v2 items above. The Mental Component Summary (MCS) weights more heavily responses to SF-12v2 items 6-9 above. The algorithm for computing the PCS and the MCS summary scores is described in the manual for the SF-12:

This manual can be purchased from QualityMetric, Inc. (www.qualitymetric.com). The PCS and MCS cannot be computed directly if a person has missing data for any of the twelve items. QualityMetric has developed a proprietary method for imputing the PCS and MCS scores if some data are missing. PCS and MCS scores calculated according to the standard algorithm, and incorporating imputations for some cases with missing data are available for analysts in this file. The PCS-12 score is PCS42, and the MCS-12 score is MCS42. Note that negative values are possible in PCS42 and MCS42 in rare cases. There are no records in 2006 where MCS42 or PCS42 is set to a negative value. Persons who were not eligible for the SAQ, or who were eligible but for whom no data existed based on SAQELIG, or who did not have a positive SAQ weight, were set to "Inapplicable" (-1) for PCS42 and MCS42. (These persons were set to missing in 2002.)

The variables PCS42 and MCS42 include cases in which the scores were imputed. SFFLAG42 indicates whether the physical component summary, PCS42, or the mental component, MCS42, were imputed for a respondent. In some cases the software could not impute a score due to amount of missing data; these cases have SFFLAG42 = 0 (No). (This represents a change from 2002, when these cases had SFFLAG42 = 1 (Yes)). Persons who were not eligible for the SAQ, or who were eligible but for whom no data existed based on SAQELIG, or who did not have a positive SAQ weight, were set to "Inapplicable" (-1) for SFFLAG42. (These persons were set to missing in 2002.)

In 2000, 2001, and 2002, MEPS used Version 1 of the SF-12. The PCS and MCS scores based on Version 1 of the SF-12 in these years were based on norms from 1990. Version 2 scores are based on norms from a 1998 national study. To appropriately compare Version 1 scores with Version 2 scores, Version 1 scores need to be rescaled to 1998 norms. This can be done by adding 1.07897 to PCS scores from Version 1, and by subtracting 0.16934 from Version 1 MCS scores. For full details, please consult the SF-12 reference manual cited above.

The 2006 SAQ includes six mental health-related questions, using the "K-6" scale developed by R.C. Kessler and colleagues. These questions assess the person’s non-specific psychological distress during the past 30 days.

A summary of the six variables above provides an index to measure non-specific, rather than disorder-specific, psychological distress. Using the following values:

The index, called K6SUM42, is a summation of the values of the six variables above. The higher the value of K6SUM42, the greater the person’s tendency towards mental disability is.

The 2006 SAQ includes two additional mental health questions. These questions assess the frequency of the person’s depressed mood and decreased interest in usual activities.

PHQ242 is a summation of the values of the two variables above, with scores ranging from 0 through 6. The higher the value of PHQ242, the greater the person’s tendency towards depression is. Kroenke et al. (2004) suggest a score of 3 as the optimal cutpoint for screening purposes. Note that these items are intended as a screening measure for depression and are not equivalent to a DSM-IV diagnosis of depression.

The SAQ included four questions that ascertain certain health-related attitudes. Two items (ADINSA42 and ADINSB42) deal with attitudes toward health insurance. The other two questions (ADRISK42 and ADOVER42) deal with attitudes that might influence decisions to purchase health insurance or to use health services. These items were used in the 1987 National Medical Expenditure Survey. No editing has been performed for these items.

Please note that the weighted frequencies displayed in the HC-099 codebook for the health status variables collected in the SAQ and DCS (as designated in the variable labels) are based on the full-year 2006 person weight PERWT06P. However, when using these variables in analysis, weights specific to each of these sets of questions should be used (SAQWT06P, DIABW06P). For persons who are not assigned a positive SAQ weight, the SAQ variables are recoded to "Inapplicable" (-1). Please see section "3.0 Survey Sample Information" for details.

The Diabetes Care Survey (DCS), a self-administered paper-and-pencil questionnaire, was fielded during Panel 10, Round 5 and Panel 11, Round 3. Households received a DCS based on their response to DIABDX53 in the Priority Condition section of the CAPI instrument, which asks whether the respondent was ever told by a doctor or health professional that he/she had diabetes. The DCS asks the same question with responses summarized in the variable DSDIA53. DSDIA53 confirms that the respondent has ever been told by a health professional that he/she had diabetes or sugar diabetes. For a small number of cases DIABDX53 =YES (1) but DSDIA53 = NO (2). These people do not have a positive DCS weight. The DCS data are unedited, and, therefore, these and other data inconsistencies remain in the data. For all persons 17 years of age or younger, all the DCS variables are set to "Inapplicable" (-1) because there is not an appropriate weight included on the file to make national estimates for this population.

DSA1C53 and DSCKFT53 indicate the number of times the respondent reported having a hemoglobin A-one-C blood test and his/her feet checked for sores or irritations in 2006, respectively. DSEY0753, DSEY0653, DSEY0553, DSEB0553 and DSEYNV53 indicate the last time the respondent reported having an eye exam in which the pupils were dilated: in 2007, in 2006, in 2005, before 2005, or never, respectively. DSKIDN53 and DSEYPR53 ascertain whether the diabetes has caused kidney or eye problems, respectively. DSDIET53, DSMED53 and DSINSU53 indicate if the respondent reported being treated for his/her diabetes by the following methods: diet, oral medications or insulin, respectively. Note that, prior to 2005, DSA1C53 did not reflect whether the person had a hemoglobin A-one-C blood test, only whether the person had a hemoglobin A-one-C test. The four variables that assess different ways the person with diabetes can learn about diabetes care are: PHONE53 (learned care over the phone), NURSE53 (learned care from a nurse), VISIT53 (learned care during a home visit), and REFER53 (learned care from a specialist). There are two variables that indicate how long it has been since the person’s last cholesterol check (CHLCHK53) and how long it has been since the person’s last flu shot (FLSHOT53).

If a respondent was unable to respond to the DCS, the questionnaire was completed by a proxy (DSPRX53 = 1). A special weight variable (DIABW06P) has been designed to be used with DCS data. This weight adjusts for DCS nonresponse and weights to the number of diabetics in the US civilian noninstitutionalized population in 2006 (see section "3.0. Survey Sample Information" for details).

Please note that the weighted frequencies displayed in the HC-099 codebook for the health status variables collected in the SAQ and DCS (as designated in the variable labels) are based on the full-year 2006 person weight PERWT06P. However, when using these variables in analysis, weights specific to each of these sets of questions should be used (SAQWT06P, DIABW06P). For persons who are not assigned a positive DCS weight, the DCS variables are recoded to "Inapplicable" (-1). Please see section "3.0. Survey Sample Information" for details.

The Disability Days section of the core interview contains questions about time lost from work or school and days spent in bed because of a physical illness or injury, or a mental or emotional problem. Data were collected on each individual in the household. These questions were repeated in each round of interviews; this file contains data from Rounds 3, 4, and 5 of the MEPS Panel 10 initiated in 2005 and Rounds 1, 2, and 3 of the MEPS Panel 11 initiated in 2006 respectively. The number at the end of the variable name (31, 42 or 53) identifies the rounds in which the information was collected.

The reference period for these questions is the time period between the beginning of the panel or the previous interview date and the current interview date. In order to establish the length of a round, analysts are referred to the variables that indicate the beginning date and ending date of each round (BEGRFD##, BEGRFM##, BEGRFY##, ENDRFD##, ENDRFM##, and ENDRFY##). Analysts should be aware that Round 3 is conducted across years. Starting in 2003, the Disability Days variables reflect only the data pertinent to the calendar year (i.e., the current delivery year of 2006). Previously, some data from Round 3 pertained to the following year. Analysts who are interested in examining disability days data across years can link to other person-level PUFs using the DUPERSID.

The flow of the Disability Days section relies on the person’s age as of the interview date. Therefore, the round-specific constructed age variables (AGE31X, AGE42X, and AGE53X) are used to construct the comparable round-specific Disability Days PUF variables. Due to the age-specific nature of the Disability Days section, age data from other rounds are not used should the person’s age for the round be missing.

The variables DDNWRK31, DDNWRK42 and DDNWRK53 represent the number of times the respondent lost a half-day or more from work because of illness, injury or mental or emotional problems during Rounds 31, 42, and 53, respectively. A response of "no work days lost" was coded zero; if the respondent did not work, these variables were coded -1 (Inapplicable). The analyst should note that there are cases where
EMPST## = 1 or 3 (has current job or job to return to) where DDNOWORK indicates work around the house only. This is because the responses to the Disability Days questions are independent of the responses to the employment questions. Respondents who were less than 16 years old or whose age is missing (AGE##X is set to -1) were not asked about work days lost, thus these variables are also coded -1 (Inapplicable).

WKINBD31, WKINBD42 and WKINBD53 represent the number of work days lost during each round in which the respondent spent at least half of the day in bed. These questions were asked only of persons aged 16 and over. Persons aged 15 or younger and persons whose age is missing received a code of -1 (Inapplicable). If a respondent answered the preceding work loss question with "zero days" or "does not work", then the corresponding WKINBD question was coded as -1 (Inapplicable).

DDNSCL31, DDNSCL42 and DDNSCL53 indicate the number of times that a respondent missed a half-day or more of school during Rounds 31, 42, or 53, respectively. These questions were asked of persons aged 3 to 22; respondents aged less than 3 or older than 22 and persons whose age is missing did not receive these questions and are coded as -1 on these variables (in a small number of cases this was not done for the 1996 data, the analyst will need to make this edit when doing longitudinal analyses). A code of -1 also indicates that the person does not attend school. The analyst should be aware that there was no attempt to reconcile school days lost with the time of year (e.g., summer vacation). In order to establish time of year, analysts are referred to the variables that indicate the beginning date and ending date of each round (BEGRFD##, BEGRFM##, BEGRFY##, ENDRFD##, ENDRFM##, and ENDRFY##).

SCLNBD31, SCLNBD42 and SCLNBD53 represent the number of school days lost during each round in which the individual spent at least a half-day in bed. Respondents aged less than 3 or older than 22 and persons whose age is missing did not receive these questions and are coded as -1 on these variables (in a small number of cases this was not done for the 1996 data, the analyst will need to make this edit when doing longitudinal analyses). If a respondent answered the preceding school days lost question with "zero days" or "does not attend school", then the corresponding SCLNBD question is coded as -1 (Inapplicable).

DDBDYS31, DDBDYS42 and DDBDYS53 represent additional days, other than school or work days, in which the respondent spent at least half a day in bed, because of a physical illness, injury or a mental or emotional problem. These are the only indicators of disability days for persons who do not work or go to school. This question was not asked of children less than one year of age and persons whose age is missing (coded -1).

A final set of variables indicate if an individual took a half-day or more off from work to care for the health problems of another individual in the family. OTHDYS31, OTHDYS42, and OTHDYS53 indicate if a person missed work because of someone else's illness, injury or health care needs, for example to take care of a sick child or relative. These variables each have three possible answers: yes - missed work to care for another (coded 1); no – did not miss work to care for another (coded 2); or the person does not work (coded 2), based on responses to the DDNWRK variable for the same round. Respondents younger than 16 and persons whose age is missing were not asked these questions and are coded as -1 (in a small number of cases this was not done for the 1996 data, the analyst will need to make this edit when doing longitudinal analyses).

OTHNDD31, OTHNDD42 and OTHNDD53 indicate the number of days during each round in which work was lost because of another's health problem. Respondents younger than 16, those whose age is missing, those who do not work, and those who answer "no" to OTHDYS are skipped out of OTHNDD and receive codes of -1.

Note that, because Disability Days variables use only those Round 3 data pertinent to the data year, it is possible to have person report missing work to care for the health problems of another individual (OTHDYS## = 1) but report no days missed (OTHNDD## = 0). This combination indicates that the person did not miss those work days during the data year. For OTHDYS31, a value of ‘0’ indicates that the person missed no work during the 2006 portion of Panel 10 Round 3 (i.e. any missed work days reported here occurred in the 2005 portion of Panel 10 Round 3). For OTHDYS53, a value of ‘0’ indicates that the person missed no work during the 2006 portion of Panel 11 Round 3 (i.e. any missed work days reported here occurred in the 2007 portion of Panel 11 Round 3).

Editing was done on these variables to preserve the skip patterns. No imputation was done for those with missing data.

The variables ACCELI42 through PMDLPR42 describe data from the Access to Care (AC) section of the MEPS HC questionnaire, which was administered in Panel 10 Round 4 and Panel 11 Round 2. This supplement serves a number of purposes in the MEPS HC by gathering information on five main topic areas: family members’ origins and preferred languages; family members’ usual source of health care; characteristics of usual source of health care providers; satisfaction with and access to the usual source of health care provider; and access to medical treatment, dental treatment, and prescription medicines. The variable ACCELI42 indicates whether persons were eligible to receive the Access to Care questions. Persons with ACCELI42 set to ‘-1’ (Inapplicable) should be excluded from estimates made with the Access to Care data.

The AC section ascertains what language is most often spoken at home (LANGHM42) and, for those households that prefer to speak Spanish or another language other than English (LANGHM42 = 2 or 3), whether all members of the household are comfortable speaking English (ENGHME42). If not all persons in the household are comfortable speaking English, the AC section asks which person is not comfortable conversing in English (ENGSPK42).

Analysts also examining 2002 data should note that, in 2002, the variable ENGSPK42 indicated the persons who were comfortable speaking English. Due to a change to the survey in 2003, ENGSPK42 now indicates those persons who are not comfortable speaking English. Therefore, ENGSPK42 = 1 (YES) in 2002 is the same as ENGSPK42 = 2 (NO) in 2003 through the present, and ENGSPK42 = 2 (NO) in 2002 is the same as ENGSPK42 = 1 (YES) in 2003 through the present.

For each individual family member, the AC section ascertains whether there is a particular doctor's office, clinic, health center, or other place that the individual usually goes to if he/she is sick or needs advice about his/her health (HAVEUS42).

YNOUSC42 indicates the main reason why a person does not have a usual source of care (USC) provider. For those family members who do not have a USC provider, question AC07 ascertains the main reason why. The variable YNOUSC42 has the following possible values:

These values reflect the answer categories given at AC07. If persons choose ‘91’ (Other Reason) at AC07, they are asked at AC07OV to provide a verbal explanation of what the main reason is that they do not have a USC provider. These "text strings" can be recoded to one of the existing categorical values listed above or, if the frequency of the response warrants it, additional categorical values. Recoding is described in greater detail below.

Family members without a USC provider are then asked AC08, which ascertains whether there are any additional reasons why. The person may choose one or more reasons. A variable is constructed for each reason why:

These variables reflect the answer categories given at AC08. If persons choose ‘91’ (Other Reason) at AC08, they are asked at AC08OV to provide a verbal explanation of what the additional reason is that they do not have a USC provider. These "text strings" can be recoded to one of the existing yes/no variables listed above or, if the frequency of response warrants it, an additional yes/no variable. Recoding is described in greater detail below.

The AC section collects information about the different characteristics of each unique USC provider for a given family. If the person does not have a USC provider (HAVEUS42 is set to ‘2’ (No), ‘-7’ (Refused), ‘-8’ (Don’t Know) or ‘-9’ (Not Ascertained)), then these variables are set to ‘-1’ (Inapplicable).

The basis for the AC provider questions is PROVTY42. This variable indicates whether the person’s provider is a facility (1), a person (2), or a person-in-facility (3). PROVTY42 is a copy of PROVTYPE (Provider Type) for persons who have a USC provider. For facility type providers, FACLPR42 indicates whether the person sees a particular provider at the facility.

Depending on how PROVTY42 is set, persons are asked about the provider’s location, the provider’s personal characteristics (e.g., race), the provider’s accessibility, and the person’s satisfaction with the provider.

Two variables indicate the location of the provider. For a facility and a person-in-facility type providers, PLCTYP42 indicates whether the person’s facility is a Hospital Clinic/Outpatient Department (1), a Hospital Emergency Room (2), or a Non-Hospital Place (3). According to CAPI flow, persons do not report the type of facility for person-type providers. Therefore, if PROVTY42 is set to ‘2’ (Person), PLCTYP42 is set to ‘-1’ (Inapplicable). For all provider types, including person-type, LOCATN42 indicates whether the person’s provider is located in an Office (1), a Hospital but Not the Emergency Room (2), or a Hospital Emergency Room (3).

For person and person-in-facility type providers, TYPEPE42 indicates what type of doctor or other medical provider the person’s provider is. The possible values include:

TYPEPE42 is constructed using variables collected at several questions: AC15 "Is provider a medical doctor?" (PROV.MEDTYPE); AC16 "Is provider a nurse, nurse practitioner, physician’s assistant, midwife, or some other kind of person?" (PROV.OTHTYPE); and AC17 "What is provider’s specialty?" (PROV.MDSPECLT). If persons choose ‘91’ (Other) at AC16 or AC17, they are asked at AC16OV or AC17OV, respectively, to provide a verbal explanation of the type of provider or medical doctor. These "text strings" can be recoded to one of the existing categorical values listed above or, if the frequency of the response warrants it, additional categorical values. Recoding is described in greater detail below.

The AC section also collects demographic information about person and person-in-facility type providers (PROVTY42 = 2 or 3). Six variables indicate the provider’s race: WHITPR42 (white), BLCKPR42 (black/African American), ASIANP42 (Asian), NATAMP42 (Indian/ Native American/Alaska Native), PACISP42 (Other Pacific Islander) and OTHRCP42 (Other Race). The person may choose more than one race for a single provider. These variables reflect the answer categories given at AC19. If persons choose ‘91’ (Some Other Race) at AC19, they are asked AC19OV to provide a verbal explanation of the provider’s race. These "text strings" can be recoded to one of the existing yes/no variables listed above or, if the frequency of response warrants it, an additional yes/no variable. Recoding is described in greater detail below.

In addition to the race variables, two other demographic variables are created: HSPLAP42 indicates whether the provider is Hispanic or Latino, and GENDRP42 indicates whether the provider is Male (1) or Female (2).

These variables describing a person’s USC provider can be used in combination to present a broader picture of the provider. For example, a person-in-facility provider with a particular person named who is a white, Hispanic, female pediatrician, with no other race specified; and whose location is in an office in a hospital is coded as:

The AC section collects information regarding the person’s ability to access the USC provider as well as the person’s satisfaction with the USC provider.

Two variables describe the person’s method of traveling to the USC provider. GOTOUS42 indicates how the person travels to the USC provider: ‘Drives’ (1), ‘Is Driven’ (2), ‘Taxi, Bus, Train, Other Public Transportation’ (3), or ‘Walks’ (4). TMTKUS42 indicates how long it takes the person to travel to the USC provider: ‘Less Than 15 Minutes’ (1), ‘15 to 30 Minutes’ (2), ‘31 to 60 Minutes’ (3), ‘61 to 90 Minutes’ (4), ‘91 Minutes to 120 Minutes’ (5), or ‘More than 120 Minutes’ (6).

OFFHOU42, DFTOUS42, PHNREG42, and AFTHOU42 assess aspects of the provider that may make it difficult for the person to get in contact with the USC provider. OFFHOU42 indicates whether the provider has office hours at night or on the weekend. The remaining three variables reflect the person’s rating of the difficulty of accessing the USC provider by travel (DFTOUS42), by phone (PHNREG42), and after hours (AFTHOU42). The person has the following choices: ‘Very Difficult’ (1), ‘Somewhat Difficult’ (2), ‘Not Too Difficult’ (3), or ‘Not at All Difficult’ (4).

These variables reflect the person’s confidence in and satisfaction with the USC provider. Four different facets of the person’s level of confidence in the USC provider are examined: Is the provider the person or place family members would go to for new health problems (MINORP42), preventive health care (PREVEN42), referrals to other health professionals (REFFRL42), or ongoing health problems (ONGONG42). The person’s level of satisfaction with the USC provider is examined in six ways: Does the USC provider generally listen to the person and seek the person’s advice when choosing between treatments (TREATM42), ask about and show respect for treatments other doctors may give the person (RESPCT42), ask the person to help make decisions (DECIDE42), explain options to the person (EXPLOP42), and speak the person’s language or provide translator services (LANGPR42) if the person prefers to speak in a language other than English (LANGHM42 is set to 2 (Spanish) or 3 (Another Language)). In 2003, all household members who share a USC provider and who live in a household where at least one person was not comfortable speaking English (ENGSPK42 = 2) had LANGPR42 set. Starting in 2004, only those persons who are not comfortable speaking English (ENGSPK42 = 1) have LANGPR42 set.

Finally, the Access to Care supplement gathers information on family members’ abilities to receive treatment and receive it without delay. These questions are split into three sections inquiring about medical, dental, and prescription medicine treatments. Each section inquires whether the person was unable to receive treatment (MDUNAB42, DNUNAB42, PMUNAB42) or was delayed in receiving treatment (MDDLAY42, DNDLAY42, PMDLAY42). A value of ‘1’ (Yes) for these two sets of variables indicates that the person needed treatment but was unable to receive it or was delayed in receiving it. A value of ‘2’ (No) for these two sets of variables indicates that either the person did not need treatment or the person needed treatment and was able to receive it without delay. If the person was unable to receive treatment, he/she was asked why (MDUNRS42, DNUNRS42, PMUNRS42). Persons were also asked why they were delayed in receiving treatment (MDDLRS42, DNDLRS42, PMDLRS42). Possible reasons include:

Finally, persons are also asked how much of a problem not receiving treatment (MDUNPR42, DNUNPR42, PMUNPR42) or being delayed in receiving treatment (MDDLPR42, DNDLPR42, PMDLPR42) was.

Editing consisted primarily of logical editing for consistency with skip patterns. Other editing included the construction of new response values and new variables describing the recoding of several "other specify" text items into existing or new categorical values, which are described below.

In previous years, not all variables or categories that appear in the Access to Care section of the HC questionnaire are included on the file, as some small cell sizes have been suppressed to maintain respondent confidentiality. No variables or categories were suppressed in 2006.

For Access to Care items AC07, AC08, AC16, AC17, and AC19, the other specify text responses were reviewed and coded as an existing or new value for the related categorical variable (for AC07, AC16, and AC17), or coded as an existing or new "yes/no" variable (for items AC08 and AC19). Note that, starting in 2005, additional categories and variables will be retained for low frequency responses to allow for pooling data.

The following are the new codes or variables which were created from these other specify text responses.

For item AC07 ("What is the main reason person does not have a usual source of health care") - the following new values were constructed for the variable YNOUSC42:

For item AC08 ("What are the other reasons person does not have a usual source of health care") – the following new variables were constructed:

OTHTYPE and MDSPECLT are used to construct the variable TYPEPE42. Unlike the other recoded variables, these variables’ text strings can be recoded to each other’s categories. For example, for persons who indicate that their USC provider is not a medical doctor (PROV.MEDTYPE = 2), the other type of USC provider is other (PROV.OTHTYPE = 91), and the text string collected is "GYNECOLOGIST", TYPEPE42 would be set to ‘4’ (MD – OB/GYN) instead of ‘11’ (OTHER NON-MD PROVIDER.)

Note that, in the 2006 data, the frequency of HEALTH42 reflects only "inapplicable" (-1) and "no" (2) responses; there are no "yes" (1) responses. Therefore HEALTH42 will not be included in this release. HEALTH42 will continue to be considered as an additional variable for the data collected at AC08 in future data years.

Employment questions were asked of all persons 16 years and older at the time of the interview. Employment variables consist of person-level indicators such as employment status and job-related variables such as hourly wage. All job-specific variables refer to a person’s current main job. The current main job, defined by the respondent, indicates the main source of employment.

Most employment variables pertain to the round interview date. The round dates are indicated by two numbers following the variable name; the first number representing the round for Panel 10 persons, the second number representing the round for Panel 11 persons. For example, EMPST31 refers to employment status on the Round 3 interview date for Panel 10 persons and employment status on the Round 1 interview date for Panel 11 persons.

With the exception of some health insurance and wage variables, no attempt has been made to logically edit any employment variables. When missing, values were imputed for certain persons’ hourly wages. Due to confidentiality concerns, hourly wages greater than or equal to $72.12 were top-coded to –10 and the number of employees variable was top-coded at 500. With the exception of a variable indicating whether the employer has more than one location (MORE), all employer-specific variables refer to the establishment that is the location of a person’s current main job.

The MEPS employment section used dependent interviewing in Rounds 2 through 5. If employment status and certain job characteristics did not change from the previous round, as identified in the review of employment section, the respondent was skipped through the main employment section. A code of "–2" is used to indicate that the information in question was obtained in a previous round. For example, if the HRWG42X (Round 4 interview date hourly wage for Panel 10 persons or Round 2 interview date hourly wage for Panel 11 persons) is coded as "–2", refer to HRWG31X (Round 3 interview date hourly wage for Panel 10 persons or Round 1 interview date hourly wage for Panel 11 persons) for the value for HRWG42X. Note that there may be a value for the Round 3/1 hourly wage or there may be an "Inapplicable" code (-1). The "–2" value for HRWG42X simply indicates that the person was skipped past the question at the time of the subsequent interview. To determine who should be skipped through various employment questions, certain information, such as employment status, had to be asked in every round and, thus, "-2" codes do not apply to employment status. Additionally, information on whether the person currently worked at more than one job or whether the person held health insurance from a current main employer was asked in every round, and, therefore, those variables also have no "–2" codes.

For Panel 10 persons who have a current main job in Round 3 that continues from Round 1 or 2, the "–2" code is not sufficient for those variables that the person was skipped past at the time of the interview. This is because the Panel 10 Round 1 and 2 data are not included on this release and therefore there are no data to which to refer. For such persons, the values for the variables for these skipped questions are copied from the Round 1 or 2 constructed variable on the 2005 Full Year Public Use Release, depending on the round in which the job first became the current main job. The accompanying variable RNDFLG31 indicates the round in which these data were collected. For example, if the person has a Round 3 current main job that continues from Round 2 and was first reported as the current main job in Round 2, HRWG31X will be a copy of the HRWG42X variable from the 2005 Full Year Public Use Release and RNDFLG31 will be "2", indicating the round in which the job was first reported as the current main job.

Employment status was asked for all persons age 16 or older. Allowable responses to the employment status questions were as follows:

These responses were mutually exclusive. A current main job was defined for persons who either reported that they were currently employed and identified a current main job or who reported and identified a job to return to. Therefore, job-specific information such as hourly wage exists for persons not presently working at the interview date but who have a job to return to as of the interview date.

The analyst should note that there are cases where EMPST## = 1 or 3 (has current job or job to return to) where DDNOWORK indicates work around the house only. This is because the responses to the Disability Days questions are independent of the responses to the employment questions.

As mentioned above, for Panel 10, if a person’s Round 3 current main job (CMJ) is a continuation CMJ from Round 2 or Round 1, the value of most "31" variables will be copied forward from the variable representing the round in which the job was first reported as the CMJ. For persons in Panel 10, RNDFLG31 indicates the round in which the Round 3 CMJ was first reported as the CMJ and provides a timeframe for the reported wage information and other job details. RNDFLG31 is used with many "31" variables to indicate the round on which the reported information is based.

RNDFLG31 is set to "Inapplicable" (–1) for persons in either panel who are under age 16 or who do not have a CMJ in Panel 10 Round 3 or Panel 11 Round 1. For persons who are part of Panel 10, RNDFLG31 is also set to "Inapplicable" (–1) if the person is out-of-scope in the 2006 portion of Round 3. For persons who are part of Panel 11, RNDFLG31 is also set to "Inapplicable" (–1) if the person is out-of-scope in Round 1. For persons who are part of Panel 10, other values for RNDFLG31 are set as follows:

For persons who are part of Panel 11 and reported a Round 1 CMJ, RNDFLG31 is set to "1" indicating that the job information represented in the "31" variables was collected in Round 1.

Information on whether an individual was self-employed at the current main job was obtained for all persons who reported a current main job. Certain questions, namely those regarding benefits and hourly wage, were not asked of the self-employed. Variables constructed from these questions indicate whether the establishment reported by wage earners (those not self-employed) as the main source of employment offered any of the following benefits:

For persons who were self-employed at their current main job, these benefits variables were coded as "Inapplicable" (-1). Additionally, information on whether the firm had more than one business location (MORE31, MORE42, and MORE53) and whether the establishment was a private for-profit, nonprofit, or a government entity (JOBORG31, JOBORG42, and JOBORG53) was not applicable for self-employed persons. Conversely, the variables that identify whether a business was incorporated, a proprietorship, or a partnership (BSNTY31, BSNTY42, and BSNTY53) applied only to those who were self-employed at their current main job.

Hourly wage was asked of all persons who reported a current main job that was not self-employment (SELFCM). HRWG31/42/53X provide the wage amount reported initially for a person’s current main job. If a current main job continues into subsequent rounds DIFFWG31/42/53 indicate if the wage has changed since the previous round. If the job continues and there is a different wage at that job, NHRWG31/42/53 indicate the new wage amount.

Some wage information was logically edited for consistency. Edits were performed under three circumstances:

In all cases that result in an edit, a complete review of wage and employment history is performed; in some cases, comparisons are made to employment at similar establishments within the MEPS as well as to data reported and summarized by the Bureau of Labor Statistics.

The initial hourly wage variables (HRWG31X, HRWG42X, HRWG53X) on this file should be considered along with their accompanying variables – HRHOW31, HRHOW42, and HRHOW53 – which indicate how the respective round hourly wage was constructed. Hourly wage could be derived, as applicable, from a large number of source variables. In the simplest case, hourly wage was reported directly by the respondent. For other persons, construction of the hourly wage was based upon salary, the time period on which the salary was based, and the number of hours worked per time period. If the number of hours worked per time period was not available, a value of 40 hours per week was assumed, as identified in the HRHOW variable.

The initial hourly wage variable HRWG31/42/53X was imputed using a weighted sequential hot-deck procedure for those identified as having a current main job who were not self-employed and who did not know their wage or refused to report a wage. Hourly wage for persons for whom employment status was not known was coded as "Not Ascertained" (-9). Additionally, wages were imputed for wage earners reporting a wage range and not a specific value. For each of these persons, a value was imputed from other persons on the file who did report a specific value that fell within the reported range. The variables HRWGIM31, HRWGIM42, and HRWGIM53 identify persons whose wages were imputed. Note that wages were imputed only for persons with a positive person and/or positive family weight.

The variable DIFFWG31/42/53 indicates whether a person’s wage amount was different in the current round at a continuing, current main job. NHRWG31/42/53 contains the updated wage amount in cases where a person indicates a change in wages (DIFFWG = 1). While the question regarding wage changes pertains to the primary wage at the main job, occasionally respondents update their supplemental wage at the main job. In these cases, users should note that HRWG31/42/53X and NHRWG31/42/53 may not differ. Users may wish to refer to the 2006 Full-Year Jobs PUF to obtain the reason for the wage change by linking on DUPERSID for the appropriate round.

For all Panel 11 Round 1 persons, DIFFWG31 and NHRWG31 are set to ‘inapplicable’ because this was the first round that wages could be reported for those persons. In Rounds 2 through 5, no imputation was performed on NHRWG31/42/53. Instead, where an updated wage amount is ‘not known’ or is ‘refused,’ NHRWG31/42/53 is set to ‘not ascertained.’ For persons whose hourly wage variable HRWG31/42/53X was imputed and the respondent provides an updated wage amount in a subsequent round, the new wage, NHRWG31/42/53, is not presented. Instead, NHRWG31/42/53 is set to ‘-13’ to indicate that the initial HRWG31/42/53X was imputed. Users may wish to refer to the 2006 Full-Year Jobs PUF to obtain updated wage amounts for these jobs.

For reasons of confidentiality, the hourly wage variables were top-coded. A value of –10 indicates that the hourly wage was greater than or equal to $72.12. As of Full-Year 2004, the wage top code process used the highest reported wage on the file for an individual regardless of whether it was reported in an HRWG31/42/53X or NHRWG31/42/53X variable. Prior to Full-Year 2004, only the initial reported wage in Rounds 3 or 1 (HRWG31X) was used to calculate the wage top code amount. Also beginning with the 2004 file, all wages for a person were top coded if any wage variable was above the top code amount.

In order to protect the confidentiality of persons across deliveries, the same top code amount used in this Full-Year Use file was also applied to the Full-Year 2006 Jobs file. Because a person can have other jobs besides a current main job which are included in the corresponding 2006 Full Year Jobs PUF, wages at these other jobs had to be reviewed in the top coding process. In some cases for these persons, wages reported at the current main job were below the top-code amount while the wage at another job had to be top coded. To further protect the confidentiality of such persons across deliveries, wages reported at all jobs in the Full-Year 2006 Jobs PUF were top coded and the wages at their current main job (HRWG31/42/53X and NHRWG31/42/53) included in this file were also top coded.

There are several employment-related health insurance measures included in this release: health insurance held at a current main job (HELD31X, HELD42X, HELD53X), health insurance offered through a current main job (OFFER31X, OFFER42X, OFFER53X), and a choice of health plans available through the current main job (CHOIC31, CHOIC42, CHOIC53).

Several persons indicated that they held health insurance through a current main job in the employment section and then denied this coverage later in the interview in the health insurance section. Employment section health insurance HELD variables were edited for consistency to match the health insurance measures obtained in the health insurance section. To allow for easy identification of these individuals, round-specific flag variables were constructed (DISVW31X, DISVW42X, DISVW53X).

Responses in the employment section for health insurance held were recoded to be consistent with the variables in the health insurance section of the survey. Due to questionnaire skip patterns, the responses to health insurance offered were affected by editing the HELD variable. For example, if a person responded that health insurance was held from a current main job, the question relating to whether health insurance was offered was skipped. For persons who responded in the employment section that they held health insurance coverage and then disavowed the coverage in the health insurance section, it could not be ascertained whether they were offered a policy. These individuals are coded as –9 for the OFFER variables.

In the first round in which a person is reported as having a specific CMJ, MEPS asks if the person holds health insurance through that job. If the person does not hold insurance, then a follow-up question is asked as to whether the person was offered insurance (but declined coverage). However, if a person does hold insurance, then that person is skipped over the offered question and the offer variable (OFFER31X, OFFER42X, OFFER53X) is automatically set to "Yes" (1).

In the rounds after a CMJ is initially reported, the "held" question is asked again in each interview (whether a person now holds insurance). This is to determine if there has been any change in coverage. Respondents with a continuing job who did not have coverage in the current round are asked if they were offered insurance. This current round information can also affect the setting of the DISVW variable as well.

In addition to this modification to OFFER, MEPS includes several clarifying questions regarding insurance availability to the jobholder through an employer. When a respondent indicates that the jobholder neither held nor was offered health insurance at the job, the respondent is asked if any other employees at the job were offered health insurance. The variable OFREMP31/42/53 indicates whether an employer offered health insurance to other employees at a firm. If a respondent indicates that other employees were eligible for health insurance, a follow-up question is asked to determine the reason the jobholder was not eligible for coverage. This information is contained in the YNOINS31/42/53 variable. The questions related to both of these variables are asked when a job is initially reported and also for subsequent rounds in which the job continues, as applicable.

Data users should note that OFREMP31/42/53 is automatically set to ‘1’ in cases where HELD and OFFER are ‘1,’ thus indicating that the jobholder has health insurance coverage through the employer, that coverage is offered to the employee, and that the employer offers insurance to its employees.

The employment-related insurance variables, HELD, OFFER, DISVW, OFREMP, and YNOINS, for each round are logically edited for consistency.

The hours measure refers to usual hours worked per week at the current main job.

The temporary job variables (TEMPJB31, TEMPJB42, TEMPJB53) indicate whether a current main job lasts for only a limited amount of time or until the completion of a project.

The seasonal job variables (SSNLJB31, SSNLJB42, SSNLJB53) indicate whether the CMJ is only available during certain times of the year. SSNLJB is "YES" (‘1’) if the job is year round; SSNLJB is "NO" (‘2’) if the job is only available during certain times of the year. Teachers and other school personnel who work only during the school year are considered to work year round.

Both variables are set on current main jobs whether a person is self-employed or not. Both are constructed based on questions that are round-specific, i.e., the questions are asked when a job is newly reported and when it is reviewed in subsequent rounds, even when the job ends in that round.

NUMEMP indicates the number of employees at the location of the person’s current main job. Due to confidentiality concerns, this variable indicating the number of employees at the establishment has been top coded at 500 or more employees. For persons who reported a categorical size, a median estimated size from donors within the reported range is used.

Information about industry and occupation types for a person’s current main job at the interview date is also contained in this release. Based on verbatim text fields collected during the interview, numeric industry and occupation codes are assigned by trained coders at the Bureau of the Census. Census uses 2003 Census Industry and Occupation Coding schemes, which were developed for the Bureau’s Current Population Survey and American Community Survey. Users should note that FY2006 coding is comparable to the FY2002 through FY2005 coding, but not coding prior to FY2002.

Current main jobs were initially coded at the 4-digit level for both industry and occupation. Then, for confidentiality reasons, these codes were condensed into broader groups for release on the file. INDCAT31, INDCAT42, and INDCAT53 represent the condensed industry codes for a person’s current main job at the interview date. OCCCAT31, OCCCAT42, and OCCCAT53 represent the condensed occupation codes for a person’s current main job at the interview date.

This release incorporates crosswalks showing how the detailed 2003 Census industry and occupation codes were collapsed into the condensed codes on the file, in both HTML and PDF formats. The same type of crosswalk is included for the pre-2002 file condensed codes, collapsed from the 1990 Census categories.

Information indicating whether a person belonged to a labor union (UNION31, UNION42, and UNION53) is also contained in this release.

The day, month, and year that the current main job started for Rounds 3, 4, and 5 of Panel 10 and Rounds 1, 2, and 3 of Panel 11 are provided in this release (STJBDD31, STJBMM31, STJBYY31, STJBDD42, STJBMM42, STJBYY42, STJBDD53, STJBMM53, and STJBYY53).

There are two measures included in this release that relate to a person’s work history over a lifetime. One indicates whether a person ever retired from a job as of the Round 5 interview date for Panel 10 persons or the Round 3 interview date for Panel 11 persons (EVRETIRE). The other indicates whether a person ever worked for pay as of the Round 5 interview date for Panel 10 persons or the Round 3 interview date for Panel 11 persons (EVRWRK). The latter was asked of everyone who indicated that they were not working as of the round interview date. Therefore, anyone who indicated current employment or who had a job during any of the previous or current rounds was skipped past the question identifying whether the person ever worked for pay. These individuals were coded as "Inapplicable" (-1). All persons who ever reported a job and were 55 years or older as of the round interview date were asked if they "ever retired". Since both of these variables are not round specific, there are no "–2" codes.

This release contains variables indicating the main reason a person did not work since the start of the reference period (NWK31, NWK42, and NWK53). If a person was not employed at all during the reference period (at the interview date or at any time during the reference period) but was employed some time prior to the reference period, the person was asked to choose from a list the main reason he or she did not work during the reference period. The "Inapplicable" (-1) category for the NWK variables includes:

A measure of whether an individual had more than one job on the round interview date (MORJOB31, MORJOB42, and MORJOB53) is provided on this release. In addition to those under 16 and those individuals who were out-of-scope, the "Inapplicable" category includes those who did not report having a current main job. Because this is not a job-specific variable, there are no "–2" codes.

This release contains variables indicating if a current main job changed between the third and fourth rounds for Panel 10 persons or between the first and second rounds for Panel 11 persons (CHGJ3142) and between the fourth and fifth rounds for Panel 10 persons or between the second and third rounds for Panel 11 persons (CHGJ4253). In addition to the "Inapplicable", "Refused", "Don’t Know", and "Not Ascertained" categories, the change job variables were coded to represent the following:

Finally, this release contains the reason given by the respondent for the job change (YCHJ3142 and YCHJ4253). The reasons for a job change were listed in the CAPI questionnaire and a respondent was asked to choose the main reason from this list. In addition to those out-of-scope, those under 16, and those not having a current main job, the "Inapplicable" category for YCHJ3142 and YCHJ4253 includes workers who did not change jobs.

Constructed and edited variables are provided that indicate any coverage in each month of 2006 for the sources of health insurance coverage collected during the MEPS interviews (Panel 10, Rounds 3 through 5 and Panel 11, Rounds 1 through 3). In Rounds 2, 3, 4, and 5, insurance that was in effect at the previous round’s interview date was reviewed with the respondent. Most of the insurance variables have been logically edited to address issues that arose during such reviews in Rounds 2, 3, 4, and 5. One edit to the private insurance variables corrects for a problem concerning covered benefits that occurred when respondents reported a change in any of their private health insurance plan names. Additional edits address issues of missing data on the time period of coverage for both public and private coverage that was either reviewed or initially reported in a given round. Additional edits, described below, were performed on the Medicare and Medicaid or State Children’s Health Insurance Program (SCHIP) variables to assign persons to coverage from these sources. Observations that contain edits assigning persons to Medicare or Medicaid/SCHIP coverage can be identified by comparing the edited and unedited versions of the Medicare and Medicaid/SCHIP variables. Starting October 1, 2001, persons 65 years and older have been able to retain TRICARE coverage in addition to Medicare. Therefore, unlike in earlier MEPS public use files, persons 65 years and older do not have their reported TRICARE coverage (TRIJA06X – TRIDE06X) overturned. TRICARE acts as a supplemental insurance for Medicare, similar to Medigap insurance.

Public sources include Medicare, TRICARE, Medicaid, SCHIP, and other public hospital/physician coverage. State-specific program participation in non-comprehensive coverage (STAJA06– STADE06) was also identified but is not considered health insurance for the purpose of this survey.

Medicare (MCRJA06 – MCRDE06) coverage was edited (MCRJA06X – MCRDE06X) for persons age 65 or over. Within this age group, individuals were assigned Medicare coverage if:

Note that age (AGE##X) is checked for edited Medicare, however date of birth is not considered. Edited Medicare is somewhat imprecise with regard to a person’s 65^th birthday.

Questions about other public hospital/physician coverage were asked in an attempt to identify Medicaid or SCHIP recipients who may not have recognized their coverage as such. These questions were asked only if a respondent did not report Medicaid or SCHIP directly. Respondents reporting other public hospital/physician coverage were asked follow-up questions to determine if their coverage was through a specific Medicaid HMO or if it included some other managed care characteristics. Respondents who identified managed care from either path were asked if they paid anything for the coverage and/or if a government source paid for the coverage.

The Medicaid/SCHIP variables (MCDJA06– MCDDE06) have been edited (MCDJA06X – MCDDE06X) to include persons who paid nothing for their other public hospital/physician insurance when such coverage was through a Medicaid HMO or reported to include some other managed care characteristics.

To assist users in further editing sources of insurance, this file contains variables constructed from the other public hospital/physician series that measure whether:

The variables OPAJA06 – OPADE06 and OPBJA06 – OPBDE06 are provided only to assist in editing and should not be used to make separate insurance estimates for these types of insurance categories.

The file also includes summary measures that indicate whether or not a sample person has any public insurance in a month (PUBJA06X – PUBDE06X). Persons identified as covered by public insurance are those reporting coverage under TRICARE, Medicare, Medicaid or SCHIP, or other public hospital/physician programs. Persons covered only by state-specific programs that did not provide comprehensive coverage (STAJA06 – STADE06), for example, the Maryland Kidney Disease Program, were not considered to have public coverage when constructing the variables PUBJA06X – PUBDE06X.

Variables identifying private insurance in general (PRIJA06 – PRIDE06) and specific private insurance sources [such as employer/union group insurance (PEGJA06 – PEGDE06); non-group (PNGJA06 – PNGDE06); and other group (POGJA06 – POGDE06)] were constructed. Private insurance sources identify coverage in effect at any time during each month of 2006. Separate variables identify covered persons and policyholders (policyholder variables begin with the letter "H", e.g., HPEJA06 – HPEDE06). These variables indicate coverage or policyholder status within a source and do not distinguish between persons who are covered or are policyholders on one or more than one policy within a given source. In some cases, the policyholder was unable to characterize the source of insurance (PDKJA06 – PDKDE06). Covered persons (but not policyholders) are identified when the policyholder is living outside the RU (POUJA06 – POUDE06). An individual was considered to have private health insurance coverage if, at a minimum, that coverage provided benefits for hospital and physician services (including Medigap coverage). Sources of insurance with missing information regarding the type of coverage were assumed to contain hospital/physician coverage. Persons without private hospital/physician insurance were not counted as privately insured. Coverage indicated by these variables may be from any type of job where the employment section insurance variables delivered on this file reflect only coverage through a current main job.

Health insurance through a job or union (PEGJA06 – PEGDE06, PRSJA06 – PRSDE06) was initially asked about in the Employment Section of the interview and later confirmed in the Health Insurance Section. Respondents also had an opportunity to report employer and union group insurance (PEGJA06 – PEGDE06) for the first time in the Health Insurance Section, but this insurance was not linked to a specific job.

All insurance reported to be through a job classified as self-employed with firm size of 1 (PRSJA06 – PRSDE06) was initially reported in the Employment Section and verified in the Health Insurance Section. Unlike the other employment-related variables (PEGJA06 – PEGDE06), self-employed-firm size 1 (PRSJA06 – PRSDE06) health insurance could not be reported in the Health Insurance section for the first time. The variables PRSJA06 – PRSDE06 have been constructed to allow users to determine if the insurance should be considered employment-related.

Private insurance that was not employment-related (POGJA06 – POGDE06, PNGJA06 – PNGDE06, PDKJA06 – PDKDE06 and POUJA06 – POUDE06) was reported in the Health Insurance section only.

The file also includes summary measures that indicate whether or not a person has any insurance in a month (INSJA06X – INSDE06X). Persons identified as insured are those reporting coverage under TRICARE, Medicare, Medicaid, SCHIP, or other public hospital/physician or private hospital/physician insurance (including Medigap plans). A person is considered uninsured if not covered by one of these insurance sources.

Persons covered only by state-specific programs that provide non-comprehensive coverage (STAJA06 – STADE06), for example, the Maryland Kidney Disease Program, and those without hospital/physician benefits (for example, private insurance for dental or vision care only, or for accidents or specific diseases) were not considered to be insured when constructing the variables INSJA06X – INSDE06X.

The variables PRVEV06-UNINS06 summarize health insurance coverage for the person in 2006 for the following types of insurance: private (PRVEV06); TRICARE (TRIEV06); Medicaid or SCHIP (MCDEV06); Medicare (MCREV06); other public A (OPAEV06); other public B (OPBEV06). Each variable was constructed based on the values of the corresponding 12 month-by-month health insurance variables described above. A value of 1 indicates that the person was covered for at least one day of at least one month during 2006. A value of 2 indicates that the person was not covered for a given type of insurance for all of 2006. The variable UNINS06 summarizes PRVEV06-OPBEV06. Where PRVEV06-OPBEV06 are all equal to 2, then UNINS06 equals 1; person was uninsured for all of 2006. Otherwise, UNINS06 is set to 2, not uninsured for some portion of 2006. For persons not in scope for the full year these summary variables are based on the period of eligibility.

For user convenience this file contains a constructed variable INSCOV06 that summarizes health insurance coverage for the person in 2006, with the following three values:

Please note that INSCOV06 categorizes TRICARE as private coverage. All other health insurance indicators included in this data release categorize TRICARE as public coverage. If an analyst wishes to consider TRICARE public coverage, the variable can easily be reconstructed using the PRVEV06 and TRIEV06 variables. Also note that these categories are mutually exclusive, with preference given to private insurance and TRICARE. Persons with both private insurance/TRICARE and public insurance will be coded as "1" for INSCOV06.

Finally, note that out-of-scope persons are coded "2" (No) for PRVEV06-INSCOV06. For all other health insurance variables in this data release, out-of-scope persons are coded "-1" (Inapplicable).

In addition to the month-by-month indicators of coverage, there are 24 round-specific health insurance variables indicating coverage by an HMO or managed care plan. Managed care variables have been constructed from information on health insurance coverage at any time in a reference period and the characteristics of the plan. A separate set of managed care variables has been constructed for private insurance Medicaid/SCHIP, and Medicare coverage. The purpose of these variables is to provide information on managed care participation during the portion of the three rounds (i.e., reference periods) that fall within the same calendar year.

Managed care variables for calendar year 2006 are based on responses to health insurance questions asked during the Round 3, 4, and 5 interviews of Panel 10, and the Round 1, 2, and 3 interviews of Panel 11. Each variable ends in "xy" where x and y denote the interview round for Panels 10 and 11, respectively. The variables ending in "31" and "42" correspond to the first two interviews of each panel in the calendar year. Because Round 3 interviews typically overlap the final months of one year and the beginning months of the next year, the "31" variables for Panel 10 have been restricted to the year 2006 portion of the reference period. Similarly, the Panel 10/Round 5 and Panel 11/Round 3 interviews have been restricted to the year 2006 portion of these reference periods, and the corresponding managed care variables have been given the suffix "06" (as opposed to "53") to emphasize the restricted time frame.

Construction of the managed care variables is straightforward, but three caveats are appropriate. First, MEPS estimates of the number of persons in HMOs are higher than figures reported by other sources, particularly those based on HMO industry data. The differences stem from the use of household-reported information, which may include respondent error, to determine HMO coverage in MEPS.

Second, the managed care questions are asked about the last plan held by a respondent through his or her establishment (employer or insurer) even though the person could have had a different plan through the establishment at an earlier point during the interview period. As a result, in instances where a respondent changed his or her establishment-related insurance, the managed care variables describe the characteristics of the last plan held through the establishment.

Third, the "06" versions of the managed care variables for Panel 11 are developed from Round 3 variables that cover different time frames. The health insurance variable for Round 3 is restricted to the same calendar year as the Round 1 and 2 data. The Round 3 variables describing plan type, on the other hand, overlap the next calendar year. As a consequence, the Round 3 managed care variables may not describe the characteristics of the last plan held in the calendar year if the person changed plans after the first of the year.

The variables PRVHMO31/42/06 and PRVMNC31/42/06 indicate coverage by a private HMO or gatekeeper plan in Panel 11, Rounds 1 – 3, and Panel 10, Rounds 3 – 5. The variables PRVDRL31/42/06 indicate coverage by a private insurance source that has a book or list of doctors in Panel 11, Rounds 1 – 3, and Panel 10, Rounds 3 – 5. The variables PRDRNP31/42/06 indicate coverage by at least one private insurance plan with a book or list of doctors that pays for visits to non-plan doctors in Panel 11, Rounds 1 – 3, and Panel 10, Rounds 3 – 5. The variables PHMONP31/42/06 indicate coverage by at least one private insurance source through an HMO that pays for visits to non-plan doctors in Panel 11, Rounds 1 – 3, and Panel 10, Rounds 3 – 5. Finally, the variables PMNCNP31/42/06 indicate coverage by at least one private insurance source through a Gatekeeper Plan that pays for visits to non-plan doctors in Panel 11, Rounds 1 – 3, and Panel 10, Rounds 3 – 5. The variables MCRPHO31/42/06 indicate coverage by a Medicare managed care plan in Panel 11, Rounds 1 - 3, and Panel 10, Rounds 3 - 5. The variables MCRPD31/42/06 indicate coverage by Medicare prescription drug benefit, also known as Part D, in Panel 11, Rounds 1 - 3, and Panel 10, Rounds 3 - 5. The edited version of the Medicare prescription drug coverage variables (MCRPD31/42/06X) include persons who are covered by both edited Medicare and edited Medicaid. The variables MCDHMO31/42/06 and MDCMC31/42/06 indicate coverage by a Medicaid or SCHIP HMO or managed care plan in Panel 11, Rounds 1 - 3, and Panel 10, Rounds 3 - 5. For Panel 11, the "31" version indicates coverage at any time in Round 1, the "42" version indicates coverage at any time in Round 2, and the "06" version represents coverage at any time during the 2006 portion of Round 3. For Panel 10, the "31" version indicates coverage at any time during the 2006 portion of Round 3, the "42" version indicates coverage at any time in Round 4, and the "06" version represents coverage at any time during Round 5 (because Round 5 ends on 12/31/06).

In the health insurance section of the questionnaire, respondents reporting private health insurance were asked to identify what types of coverage they had via a checklist. If they selected prescription drug or dental coverage from this checklist, variables were constructed to indicate prescription drug or dental coverage respectively. It should be noted, however, that in some cases respondents may have failed to identify prescription drug or dental coverage that was included as part of a hospital and physician plan.

Round specific variables are provided that indicate which TRICARE plan the respondent was covered by for each round of 2006. These variables indicate whether the person was covered by TRICARE Standard (TRIST31/42/06X), TRICARE Prime (TRIPR31/42/06X), TRICARE Extra (TRIEX31/42/06X), and TRICARE for Life (TRILI31/42/06X). Beginning Panel 9 Rounds 4 and 5/Panel 10 Rounds 1 through 3, CHAMPVA was added to the list of Tricare Plans collected in the instrument. Therefore, the variables TRICH42/06X were created. The "31" version of this variable was not constructed in 2005, but was constructed starting in 2006. It should be noted that the TRICARE Plan information was elicited from a pick-list, code all that apply, question that asked which type of TRICARE plan the person obtained. It should also be noted that the TRICARE plan question was asked at the RU-level, that is, if any person in the RU reported coverage under TRICARE, a follow-up question was asked to determine which TRICARE plan anyone in the RU was covered by. After indicating the specific TRICARE plan or plans for the RU, a second question was asked to determine who in the RU was covered by TRICARE. In each round, each TRICARE Plan variable has five possible values:

Persons were assigned Medicare coverage based on their responses to the health insurance questions or through logical editing of the survey data. A small number of persons were edited to have Medicare and for this group coverage through a managed care plan and coverage by prescription drug plan questions were not asked. Since no Medicare establishment-person pair exists for this group, the persons’ Medicare managed care and prescription drug benefit statuses are set to not ascertained. For those persons who reported Medicare coverage based on their responses to the health insurance questions, the Medicare managed care plan and prescription drug benefit questions were asked. These questions were asked for each round a person indicates Medicare coverage.

The Medicare prescription drug benefit variables (MCRPD31/42/06) have been edited (MCRPD31/42/06X) to turn on coverage for all persons who are covered by both edited Medicare and edited Medicaid regardless of the status on their unedited Medicare prescription drug benefit variable.

In each round, the variables MCRPHO31, MCRPHO42, and MCRPHO06 have five possible values:

In each round, the variables MCRPD31(X), MCRPD42(X), and MCRPD06(X) have five possible values:

Persons were assigned Medicaid or SCHIP coverage based on their responses to the health insurance questions or through logical editing of the survey data. The number of persons who were edited to have Medicaid or SCHIP coverage is small, but they are comprised of two distinct groups of individuals. The first group includes persons in Other Government programs that were identified as being in a Medicaid HMO or gatekeeper plan that did not require premium payment from the insured party. By definition, this group was asked about the managed care characteristics of their insurance coverage. The second group includes a small number of persons who did not report public insurance, but were classified as Medicaid recipients because they reported receiving AFDC, SSI, or WIC. The health insurance plan type questions were not asked of this group. As a consequence, the plan type could be determined for some, but not all, respondents who were assigned Medicaid coverage through logical editing of the data.

If Medicaid/SCHIP or Other Government programs were identified as the source of hospital/physician insurance coverage, the respondent was asked about the characteristics of the plan. The variables MCDHMO31, MCDHMO42, and MCDHMO06 have been set to "Yes" if the plan was identified from a list of state names or programs for Medicaid HMOs in the area, or if an affirmative response was provided to the following question:

In subsequent rounds, respondents who had been previously identified as covered by Medicaid were asked whether the name of their insurance plan had changed since the previous interview. An affirmative response triggered the previous set of questions about managed care (name on list of Medicaid HMOs or signed up with an HMO).

In each round, the variables MCDHMO31, MCDHMO42, and MCDHMO06 have five possible values:

If the respondent did not belong to a Medicaid/SCHIP HMO, a third question was used to determine whether the person was in a gatekeeper plan. The variables MCDMC31, MCDMC42, and MCDMC06 were set to "Yes" if the person provided an affirmative response to the following question:

In each round, the variables MCDMC31, MCDMC42, and MCDMC06 have five possible values:

Persons with private insurance were identified from their responses to questions in the health insurance section of the MEPS questionnaire. In some cases, persons were assigned private insurance as a result of comments collected during the interview, but data editing was minimal. As a consequence, most persons with private insurance were asked about the characteristics of their plan, and their responses were used to identify HMO and gatekeeper plans.

Persons with private insurance were classified as being covered by an HMO if they met any of the three following conditions:

In subsequent rounds, policyholders were asked whether the name of their insurance plan had changed since the previous interview. An affirmative response triggered the detailed question about managed care (i.e., was the insurer an HMO).

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as an HMO, the variables PRVHMO31, PRVHMO42, and PRVHMO06 were set to "Yes." If a person had multiple plans and one or more were identified as not being an HMO and the other(s) had missing plan type information, the person-level variable was set to missing. Additionally, if a person had multiple plans and none were identified as an HMO, the person-level variable was set to "No." In each round, the variables PRVHMO31, PRVHMO42, and PRVHMO06 have five possible values:

If the respondent did not report belonging to a private HMO, a follow-up question was used to determine whether the person was in a gatekeeper plan. Persons with private insurance were classified as being covered by a gatekeeper plan if the person provided an affirmative response to the following question:

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as a gatekeeper plan, the variables PRVMNC31, PRVMNC42, and PRVMNC06 were set to "Yes." If a person had multiple plans and one or more were identified as not being a gatekeeper plan and the other(s) had missing plan type information, the person-level variable was set to missing. Additionally, if a person had multiple plans and none were identified as a gatekeeper plan, the person-level variable was set to "No". In each round, the variables PRVMNC31, PRVMNC42, and PRVMNC06 have five possible values:

If the respondent did not report belonging to a private gatekeeper plan, a follow-up question was used to determine whether the person belonged to a plan that had a book or list of doctors. Persons with private insurance were classified as being covered by such a plan if the person provided an affirmative response to the following question:

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan that had a book or list of doctors, the variables PRVDRL31, PRVDRL42, and PRVDRL06 were set to "Yes". If a person had multiple plans and one or more were identified as not being a plan that had a book or list of doctors and the other(s) had missing information, the person-level variable was set to missing. Additionally, if a person had multiple plans and none were identified as a plan that had a book or list of doctors, the person-level variable was set to "No". In each round, the variables PRVDRL31, PRVDRL42, and PRVDRL06 have five possible values:

If the respondent reported that they belong to a private HMO plan, a follow up question was used to determine whether the person was in a plan that pays for visits to non-plan doctors. Persons with private HMO insurance were classified as being covered by a plan that pays for visits to non-plan doctors if the person provided an affirmative response to the following question:

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as an HMO plan that pays for visits to non-plan doctors, the variables PHMONP31, PHMONP42, and PHMONP06 were set to "Yes". If a person had multiple plans and one or more were identified as being an HMO plan that does not pay for visits to non-plan doctors and the other(s) had missing information, the person-level variable was set to missing. Additionally, if a person had multiple plans and one or more were identified as being an HMO but none were identified as an HMO plan that pays for visits to non-plan doctors, the person-level variable was set to "No". In each round, the variables PHMONP31, PHMONP42, and PHMONP06 have four possible values:

If the respondent reported that they belong to a private gatekeeper plan, a follow up question was used to determine whether the person was in a plan that pays for visits to non-plan doctors. Persons with private gatekeeper insurance were classified as being covered by a plan that pays for visits to non-plan doctors if the person provided an affirmative response to the following question:

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as a gatekeeper plan that pays for visits to non-plan doctors, the variables PMNCNP31, PMNCNP42, and PMNCNP06 were set to "Yes." If a person had multiple plans and one or more were identified as being a gatekeeper plan that does not pay for visits to non-plan doctors and the other(s) had missing information, the person level variable was set to missing. Additionally, if a person had multiple plans and one or more was identified as being a gatekeeper plan, but none were identified as a gatekeeper plan that pays for visits to non-plan doctors, the person level variable was set to "No." In each round, the variables PMNCNP31, PMNCNP42, and PMNCNP06 have four possible values:

If the respondent reported that they belong to a plan that had a book or list of doctors, a follow up question was used to determine whether the person was in a plan that pays for visits to non-plan doctors. Persons with a private insurance plan that has a book or list of doctors were classified as being covered by a plan that pays for visits to non-plan doctors if the person provided an affirmative response to the following question:

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as a plan that had a book or list of doctors and that pays for visits to non-plan doctors, the variables PRDRNP31, PRDRNP42, and PRDRNP06 were set to "Yes." If a person had multiple plans and one or more were identified as being a plan that had a book or list of doctors that does not pay for visits to non-plan doctors and the other(s) had missing information, the person-level variable was set to missing. Additionally, if a person had multiple plans and one or more were identified as being a plan with a book of list of doctors, but none were identified as a plan that had a book or list of doctors that pays for visits to non-plan doctors, the person-level variable was set to "No." In each round, the variables PRDRNP31, PRDRNP42, and PRDRNP06 have four possible values:

If a person was identified as being without insurance as of January 1^st in the MEPS Round 1 interview, a series of follow-up questions were asked to determine the duration of uninsurance prior to the start of the MEPS survey. Persons who were insured as of the MEPS Round 1 interview, and persons with a date of birth on or after December 31, 2005 or whose age category was less than 1 year old were skipped past this loop of questions. These questions are asked in Round 1 only.

If the person said he/she was covered by insurance in the two years prior to the MEPS Round 1 interview (PREVCOVR), the month, year (COVRMM, COVRYY), and type of coverage (Employer-sponsored (WASESTB), Medicare (WASMCARE), Medicaid/SCHIP (WASMCAID), TRICARE/CHAMPVA (WASCHAMP), VA/Military Care (WASVA), Other public (WASOTGOV, WASAFDC,WASSSI, WASSTAT1-4, WASOTHER) or Private coverage purchased through a group, association or insurance company (WASPRIV)) was ascertained. Note that under the types of coverage, up to 4 state programs (WASSTAT1-4) can be listed as response options, but only the number of programs available in the state in which the RU is located (up to 4) will be displayed. If the state in which the RU is located has less than 4 state programs available, the remaining state programs will be -1 (Inapplicable). The only exception is if the response is Refused (-7) or Don't Know (-8). In that case, WASTAT1-4 are all coded with the same missing value, regardless of the number of plans available in that specific state. Note that this is a code all that apply question, so more than one source of previous insurance can be selected. For persons who were covered by health insurance on January 1^st, it was ascertained if they were ever without health insurance in the previous year (NOINSBEF). The number of weeks/months without health insurance was also ascertained (NOINSTM, NOINUNIT). For persons who reported only non-comprehensive coverage as of January 1^st, a question was asked to determine if they had been covered by more comprehensive coverage that paid for medical and doctors’ bills in the previous two years (MORECOVR). If they were, the most recent month and year of coverage was ascertained (INSENDMM, INSENDYY) as was the type of coverage (see the variable names above).

Note that these variables are unedited and have been taken directly as they were recorded from the raw data. There may be inconsistencies with the health insurance variables released on public use files that indicate that an individual is uninsured in January. Out-of-scope persons in both panels and all persons in Panel 10 have been set to "Inapplicable" (-1) for PREVCOVR – INSENDYY. All other persons have PREVCOVR – INSENDYY copied directly from the value of the unedited source variable.

Persons whose January 1^st insurance coverage status could not be determined due to their reference period beginning after January 1^st were also asked the follow-up questions described above. In these cases, persons who reported comprehensive coverage were asked if they were ever without insurance. Those who were uninsured were asked to determine the duration of uninsurance prior to the start of their reference period. Those who reported only non-comprehensive coverage were asked if they had been covered by comprehensive coverage that paid for medical and doctors’ bills in the previous two years. Coverage is determined by health insurance status during the whole reference period or the month of January and ignores that these persons were not in the household on January 1^st.

Constructed and edited variables are provided that indicate health insurance coverage at any time in a given round as well as at the MEPS interview dates and on December 31, 2006. Note that for respondents who left the RU before the MEPS interview date or before December 31^st, the variables measuring coverage at the interview date or on December 31^st represent coverage at the date the person left the RU. In addition, since Round 5 only covers the time period from the Round 4 interview date up to December 31^st, values for the December 31^st variables are equivalent to those for Round 5 variables for Panel 10 members.

The health insurance variables are constructed for the sources of health insurance coverage collected during the MEPS interviews (Panel 10, Rounds 3 through 5 and Panel 11, Rounds 1 through 3). Note that the Medicare variables on this file as well as the private insurance variables that indicate the particular source of private coverage (rather than any private coverage) only measure coverage at the interview date and on December 31^st. Users should also note that the same general editing rules were followed for the month-by-month health insurance variables released on this public use file (see section 2.5.8.1 for details). Editing programs checking for consistencies between these sets of variables were developed in order to provide as much consistency as possible between the round-specific indicators and the month-by-month indicators of insurance.

Public sources include Medicare, TRICARE, Medicaid/SCHIP, and other public hospital/physician coverage. State-specific program participation in non-comprehensive coverage was also identified but is not considered health insurance for the purpose of this survey.

Medicare coverage variables (MCARE31, MCARE42, MCARE53 and MCARE06) and the edited versions of these variables (MCARE31X, MCARE42X, MCARE53X and MCARE06X) were constructed similarly to the month-by-month Medicare variables.

Medicaid/SCHIP variables (MCAID31, MCAID42, MCAID53, MCAID06) and the edited versions of these variables (MCAID31X, MCAID42X, MCAID53X, MCAID06X, MCDAT31X, MCDAT42X, MCDAT53X, MCDAT06X) were constructed similarly to the month-by-month Medicaid/SCHIP variables.

Other Public A variables (OTPUBA31, OTPUBA42, OTPUBA53, OTPUBA06; and OTPAAT31, OTPAAT42, OTPAAT53, OTPAAT06) were constructed similarly to the month-by-month Other Public variables

Any public insurance variables (PUB31X, PUB42X, PUB53X, PUB06X, PUBAT31X, PUBAT42X, PUBAT53X, and PUBAT06X) and state-specific programs that provide non-comprehensive coverage variables (STAPR31, STAPR42, STAPR53, STAPR06, STPRAT31, STPRAT42, STPRAT53, and STPRAT06) were constructed similarly to the month-by-month any public insurance and state-specific program variables.

Variables identifying private insurance in general (PRIV31, PRIV42, PRIV53, PRIV06, PRIVAT31, PRIVAT42, PRIVAT53, PRIVAT06) and specific private insurance sources (such as employer/union group insurance [PRIEU31, PRIEU42, PRIEU53, PRIEU06]; coverage through a job classified as self-employed with firm size of 1 [PRIS31, PRIS42, PRIS53, PRIS06]; non-group coverage [PRING31, PRING42, PRING53, PRING06]; other group coverage (PRIOG31, PRIOG42, PRIOG53, PRIOG06], coverage through an unknown private category [PRIDK31, PRIDK42, PRIDK53, PRIDK06]; and coverage from a policyholder living outside the RU [PROUT31, PROUT42, PROUT53, PROUT06]) were constructed similarly to the month-by-month variables in section 2.5.8.1. Variables indicating any private insurance coverage are available for the following time periods: at any time in a given round, at the interview date and on December 31^st. The variables for the specific sources of private coverage are only available for coverage on the interview dates and on December 31^st.

Any insurance variables (INS31X, INS42X, INS53X, INS06X, INSAT31X, INSAT42X, INSAT53X, and INSAT06X) and state-specific programs that provide non-comprehensive coverage variables (STAPR31, STAPR42, STAPR53, STAPR06, STPRAT31, STPRAT42, STPRAT53, and STPRAT06) were constructed similarly to the month-by-month any insurance and state-specific program variables.

The variable EVRUNINS indicates whether a person was ever uninsured on the interview date or on 12/31. If the person is uninsured on the interview date/on 12/31 for any round that they were in-scope (INS##X = 2), EVRUNINS is coded as "Yes" (1). If the person is insured on the interview date/on 12/31 for all rounds that they were in-scope (INS##X = 1), EVRUNINS is coded as "No" (2). The variable EVRUNAT indicates whether a person was ever uninsured at any time in 2006. If the person is uninsured at any time in the round for any round that they were in-scope (INSAT##X = 2), EVRUNAT is coded as "Yes" (1). If the person is insured at any time in the round for all rounds that they were in-scope (INSAT##X = 1), EVRUNAT is coded as "No" (2). EVRUNINS and EVRUNAT are coded "Inapplicable" (-1) for persons who were out-of-scope for all rounds.

Round specific variables (DENTIN31/42/53) are provided that indicate the respondent was covered by a private health insurance plan that included at least some dental coverage for each round of 2006. It should be noted that the information was elicited from a pick-list, code all that apply, question that asked what type of health insurance a person obtained through an establishment. The list included: hospital and physician benefits including coverage through an HMO, Medigap coverage, vision coverage, dental, and prescription drugs. It is possible that some dental coverage provided by hospital and physician plans was not independently enumerated in this question. Users should also note that persons with missing information on dental benefits for all reported private plans and those who reported that they did not have dental coverage for one or more plans but had missing information on other plans are coded as not having private dental coverage. Respondents who reported dental coverage from at least one reported private plan were coded as having private dental coverage.

Currently, the DENTIN53 variable reflects coverage for all of Panel 11 Round 3 where the end reference year could extend into 2007. DENTIN31 for Panel 10 Round 3 reflects coverage in 2005 and 2006 since the Round 3 reference period spans both years. Beginning 2006, a new version of these dental coverage indicators was built to reflect only current year coverage (DNTINS31/06).

Round specific variables (PMEDIN31/42/53) are provided that indicate the respondent was covered by a private health insurance plan that included at least some prescription drug insurance coverage for each round of 2006. It should be noted that the information was elicited from a pick-list, code all that apply, question that asked what type of health insurance a person obtained through an establishment. The list included: hospital and physician benefits including coverage through an HMO, Medigap coverage, vision coverage, dental, and prescription drugs. It is possible some prescription drug coverage provided by hospital and physician plans was not independently enumerated in this question. Respondents who reported prescription drug coverage from at least one reported private plan were coded as having private prescription drug coverage. Users should note that persons with missing information on prescription drug benefits for all reported private plans and those who reported that they did not have prescription drug coverage for one or more plans but had missing information on other plans are coded as not having private prescription drug coverage.

Currently, the PMEDIN53 variable reflects coverage for all of Panel 11 Round 3 where the end reference year could extend into 2007. PMEDIN31 for Panel 10 Round 3 reflects coverage in 2005 and 2006 since the Round 3 reference period spans both years. Beginning 2006, a new version of these prescription drug coverage indicators was built to reflect only current year coverage (PMDINS31/06).

Round specific variables are provided that indicate whether the respondent has a usual third party payer for prescription medications (PMEDUP31/42/53), and if so, what type of payer (PMEDPY31/42/53). Only respondents that reported having at least one prescription medication purchase in the round are asked these questions. If the respondent answers affirmatively to PMEDUP31/42/53 they are then asked the name of their usual third party payer. These responses are coded into the following source of payment categories reported in the PMEDPY31/42/53: Private Insurance, Medicare, Medicaid, VA, Tricare/CHAMPVA, State/Local Government, and Other. Users should note that these questions are asked in the charge and payment section of the questionnaire, and that no attempt is made to reconcile the responses with information collected in the health insurance section of the questionnaire.

The variables GDCPBM42 through RTPLNT42 contain responses to the satisfaction with plans supplement, which was administered in the second and fourth interviews of the MEPS HC. Question wording is based on questions in the Consumer Assessment of Healthcare Providers and Systems (CAHPS®), an AHRQ-sponsored family of survey instruments designed to measure quality from the consumer’s perspective. There are two sets of variables, one for TRICARE/CHAMPVA and the other for Medicaid, SCHIP, or other state or local government hospital/physician coverage, because families may have both types of insurance. Family respondents who reported any current family member had TRICARE/CHAMPVA in that round were asked about the family’s experiences with TRICARE/CHAMPVA. These family- (RU-) level responses do not vary across RU members with TRICARE/CHAMPVA at any time during the round; for RU members without TRICARE/CHAMPVA during the round, the values are set to inapplicable.

Family respondents who reported any current family member had Medicaid, SCHIP, or other state or local government hospital/physician coverage in that round were asked about the family’s experiences with that coverage. These RU-level responses do not vary across RU members who at any time during the round had Medicaid, SCHIP, or other state or local government hospital/physician coverage. For RU members without these types of public insurance during the round, the values are set to inapplicable.

The variables address the following topics: difficulty getting a personal doctor or nurse (GDCPBM42 and GDCPBT42), needing approval for treatment and delays associated with waiting for approval (APRTRM42, APRDLM42, APRTRT42, APRDLT42), looking for information on how plan works and problems finding information (LKINFM42, PBINFM42, LKINFT42, PBINFT42), calling customer service and problems getting help from customer service (CSTSVM42, PBSVCM42, CSTSVT42, PBSVCT42), filling out paperwork for the plan and problems with the paperwork (PPRWKM42, PBPWKM42, PPRWKT42, PBPWKT42), rating of experience with plan (RTPLNM42 and RTPLNT42).

Variables for experiences with private plans are on the 2006 Person Round Plan file, PUF HC-103. On that file, each person has a separate record for each private plan, and each record has variables with the family’s experiences with that specific plan.

The MEPS Household Component (HC) collects data in each round on use for office- and hospital-based care, home health care, dental services, and prescribed medicines. Data were collected for each sample person at the event level (e.g., doctor visit, hospital stay) and summed across Rounds 3 – 5 for Panel 10 (excluding 2005 events covered in Round 3) and across Rounds 1 – 3 for Panel 11 (excluding 2007 events covered in Round 3) to produce the annual utilization counts for 2006. This file contains utilization variables for several categories of health care services. In general, there is one utilization variable for each category of health care service. The utilization variable is typically a count of the number of medical events reported for the category. (Expenditure variables are not included on this file and will be provided in the forthcoming 2006 Income and Expenditure file.)

The following sections summarize definitional, conceptual, and analytic considerations when using the utilization variables in this file. Separate discussions are provided for each MEPS medical service category.

Medical provider visits consist of encounters that took place primarily in office-based settings and clinics. Care provided in other settings such as a hospital, nursing home, or a person’s home are not included in this category.

The total number of office-based visits reported for 2006 (OBTOTV06) as well as the number of such visits to physicians (OBDRV06) and non-physician providers (OBOTHV06) are contained in this file. For a small proportion of sample persons, the sum of the physician and non-physician visit variables (OBDRV06 + OBOTHV06) is less than the total number of office-based visits variable (OBTOTV06) because OBTOTV06 contains reported visits where the respondent did not know the type of provider.

Non-physician visits (OBOTHV06) include visits to the following types of providers: chiropractors, midwives, nurses and nurse practitioners, optometrists, podiatrists, physician’s assistants, physical therapists, occupational therapists, psychologists, social workers, technicians, receptionists/clerks/secretaries, or other medical providers. Separate utilization variables are included for selected types of more commonly seen non-physician providers including chiropractors (OBCHIR06), nurses/nurse practitioners (OBNURS06), optometrists (OBOPTO06), physician assistants (OBASST06), and physical or occupational therapists (OBTHER06).

Separate utilization variables for hospital care are provided for each type of setting (outpatient department, emergency room, and inpatient stays).

Variables for the total number of reported visits to hospital outpatient departments in 2006 (OPTOTV06) as well as the number of outpatient department visits to physicians (OPDRV06) and non-physician providers (OPOTHV06) are contained in this file. For a small proportion of sample persons, the sum of the physician and non-physician visit variables (OPDRV06 + OPOTHV06) is less than the total number of outpatient visits variable (OPTOTV06) because OPTOTV06 contains reported visits where the respondent did not provide information on the type of provider seen.

The variable ERTOT06 represents a count of all emergency room visits reported for the survey year.

Data used to construct the inpatient utilization variables for newborns were edited to exclude stays where the newborn left the hospital on the same day as the mother. This edit was applied because discharges for infants without complications after birth were not consistently reported in the survey. However, if the newborn was discharged at a later date than the mother was discharged, then the discharge was considered a separate stay for the newborn when constructing the utilization variables.

Some analysts may prefer to exclude "zero night stays" from inpatient analyses and/or count these stays as ambulatory visits. Therefore, a separate use variable is provided that contains a count of the number of inpatient events where the reported dates of admission and discharge were the same (IPZERO06). This variable can be subtracted from IPDIS06 to exclude "zero night stays" from inpatient utilization estimates.

The total number of dental care visits variable (DVTOT06) includes those to any person(s) for dental care including general dentists, dental hygienists, dental technicians, dental surgeons, orthodontists, endodontists, and periodontists. Additional variables are provided for the numbers of dental visits to general dentists (DVGEN06) and to orthodontists (DVORTH06).

In contrast to other types of medical events where data were collected on a per visit basis, information on home health care utilization is collected in MEPS on a per month basis. Variables are provided that indicate the total number of days in 2006 where home health care was received from the following: from any type of paid or unpaid caregiver (HHTOTD06), from agencies, hospitals, or nursing homes (HHAGD06), from self-employed persons (HHINDD06), and from unpaid informal caregivers not living with the sample person (HHINFD06). The number of provider days represents the sum across months of the number of days on which home health care was received, with days summed across all providers seen. For example, if a person received care in one month from one provider on two different days, then the number of provider days would equal 2. The number of provider days would also equal 2 if a person received care from two different providers on the same day. However, if a person received care from one provider two times on the same day, then the provider days would equal 1. These variables were assigned missing values if the number of provider days could not be computed for any month in which the specific type of home health care was received.

Records on this file can be linked to 2006 MEPS-HC public use event and condition files by the sample person identifier (DUPERSID). The Panel 10 cases on this file (PANEL=10) can also be linked back to the 2005 MEPS-HC public use event and condition files.

The set of households selected for MEPS is a subsample of those participating in the National Health Interview Survey (NHIS), thus, each MEPS panel can also be linked back to the previous year’s NHIS public use data files. For information on obtaining MEPS/NHIS link files please see www.meps.ahrq.gov/data_stats/more_info_download_data_files.jsp.

To facilitate analysis of subpopulations and/or low prevalence events, it may be desirable to pool together more than one year of data to yield sample sizes large enough to generate reliable estimates. For more details on pooling MEPS data files see www.meps.ahrq.gov/data_stats/download_data_files_detail.jsp?cboPufNumber=HC-036.

Starting in Panel 9, values for DUPERSID from previous panels will occasionally be re-used. Therefore, it is necessary to use the panel variable (PANEL) in combination with DUPERSID to ensure unique person-level identifiers across panels. Creating unique records in this manner is advised when pooling MEPS data across multiple annual files that have one or more identical values for DUPERSID.

Panel-specific files containing estimation variables to facilitate longitudinal analysis are available for downloading in the data section of the MEPS Web site.

The MEPS is designed to produce estimates at the national and regional level over time for the civilian, noninstitutionalized population of the United States and some subpopulations of interest. The data in this public use file pertain to calendar year 2006. The data were collected in Rounds 1, 2, and 3 for MEPS Panel 11 and Rounds 3, 4, and 5 for MEPS Panel 10. (Note that Round 3 for a MEPS panel is designed to overlap two calendar years, see illustration below.)

Variables convey the same information for this full-year file that has been provided for the full-year files associated with years 1996 – 2005 of MEPS.

The only utilization data that appear on this file are those associated with health care events occurring in calendar year 2006. All such utilization data for 2006 reported by MEPS respondents regardless of round and panel have been included in this database.

There have been some published reports on the MEPS sample design. For detailed information on the MEPS sample design for Panel 1, see Cohen, S. Sample Design of the 1996 Medical Expenditure Panel Survey Household Component. Rockville (MD): Agency for Health Care Policy and Research; 1997. MEPS Methodology Report, No. 2. AHCPR Pub. No. 97-0027. For detailed information on the MEPS sample design for Panel 2, see Cohen, S., Sample Design of the 1997 Medical Expenditure Panel Survey Household Component.

First note that the 2006 MEPS database is the last one to be based solely on the NHIS sample design first implemented in 1995. Beginning in 2006 the NHIS implemented a new, though similar, sample design.

The households in this 2006 MEPS database are related to a subsample of households participating in the NHIS in 2004 and 2005. The households (occupied DUs) selected for MEPS Panel 10 were a subsample of the 2004 NHIS responding households, while those in MEPS Panel 11 were a subsample of 2005 NHIS respondents. A household may contain one or more family units, each consisting of one or more individuals. Analysis can be undertaken using either the individual or the family as the unit of analysis.

There were 8,564 households (occupied DUs) selected for inclusion in MEPS Panel 10, of which 8,505 were eligible for fielding (college dormitories were eliminated). They were selected as a nationally representative subsample of the households responding to the 2004 NHIS. A subsample of 9,464 households was selected for MEPS Panel 11 from among households responding to the 2005 NHIS, of which 9,434 were fielded after the elimination of college dorms.

The NHIS is a complex multi-stage sample design. A brief and simplified description of the NHIS design follows. The first stage of sample selection is an area sample of PSUs, where PSUs generally consist of one or more counties. Within PSUs, density strata are formed, generally reflecting the density of minority populations for single or groups of blocks or block equivalents that are assigned to the strata. Within each such density stratum "supersegments" are formed, consisting of clusters of housing units. Samples of supersegments are selected for use over a 10-year data collection period for the NHIS. Households within supersegments are selected for each calendar year the NHIS is carried out. Households containing Hispanics and Blacks are oversampled at rates of approximately 2 and 1.5 times, respectively, the rate of remaining households. The only major difference in eligibility status for housing units between NHIS and MEPS is that college dorms represent ineligible housing units for MEPS. College aged students living away from home during the school year were interviewed at their place of residence for the NHIS but were identified by and linked to their parents’ household for MEPS. (There is also a person-level stage of sampling for the NHIS, but that does not have a direct impact on the MEPS sample design.)

In the database "MEPS HC-099: 2006 Full Year Population Characteristics," weight variables are provided for generating MEPS estimates of totals, means, percents, and rates for persons and families in the civilian noninstitutionalized population. Procedures and considerations associated with the construction and interpretation of person and family-level estimates using these and other variables are discussed below.

Generally, a sample representing about three-eighths of the NHIS responding households is made available for use in MEPS. A subsample of these households is then drawn for MEPS interviewing. Because the MEPS subsampling has to be done soon after NHIS responding households are identified, a small percentage of the NHIS households initially characterized as NHIS respondents are later classified as nonrespondents for the purposes of NHIS data analysis. This actually serves to increase the overall MEPS response rate slightly since the percentage of NHIS households designated for use in MEPS (all those characterized initially as respondents from the NHIS panels and quarters used by MEPS for a given year) is slightly larger than the final NHIS household-level response rate and some NHIS nonresponding households do participate in MEPS. However, as a result, these NHIS nonrespondents who are MEPS participants have no NHIS data available to link with MEPS data.

Once the MEPS sample is selected from among the NHIS households characterized as NHIS respondents, RUs representing students living in student housing or consisting entirely of military personnel are deleted from the sample. For the NHIS, college students living in student housing are sampled independently from their families. For MEPS, such students are identified through the sample selection of their parents' RU. Removing from MEPS those college students found in college housing sampled for the NHIS eliminates the opportunity of multiple chances of selection for MEPS for these students. Military personnel not living in the same RU as civilians are ineligible for MEPS. After such exclusions, all RUs associated with households selected from among those identified as NHIS responding households are then fielded in the first round of MEPS.

Table 3.1 shows these three informational components just discussed in Rows A, B, and C. Row A indicates the percentage of NHIS households eligible for MEPS. Row B indicates the number of NHIS households sampled for MEPS. Row C indicates the number of sampled households actually fielded for MEPS (after dropping the students and military members discussed above).

Table 3.1. Sample size and Response rates for Full Year file (Panel 11 Rounds 1-3/Panel 10, Rounds 3-5)

In order to produce annual health care estimates for calendar year 2006 based on the full MEPS sample, data from the MEPS Panel 10 and Panel 11 samples are combined. More specifically, full calendar year 2006 data collected in Rounds 3 through 5 for the MEPS from the Panel 10 sample are combined with data from the first three rounds of data collection for the MEPS Panel 11 sample (the general approach is described below).

To understand the calculation of MEPS response rates, some features related to MEPS data collection should be noted. When an RU is visited for a round of data collection, changes in RU membership are identified. Such changes include RU members who have moved to another location in the U.S., thus creating a new RU to be interviewed for MEPS, as well as student RUs. Thus, the number of RUs eligible for MEPS interviewing in a given round can only be determined after data collection is fully completed. The ratio of the number of RUs completing the MEPS interview in a given round to the number of RUs characterized as eligible to complete the interview for that round represents the "conditional" response rate for that round expressed as a proportion. It is "conditional" in that it pertains to the set of RUs characterized as eligible for MEPS for that round, and thus is "conditioned" on prior participation rather than representing the overall response rate through that round. For example, in Table 3.1, for Panel 10, Round 2 the ratio of 6,940 (Row G) to 7,381 (Row F) multiplied by 100 represents the percentage response rate for the round (94.0 percent when computed), conditioned on the set of RUs characterized as eligible for MEPS for that round. Taking the product of the percentage of the NHIS sample eligible for MEPS (row A) with the product of the ratios for a consecutive set of MEPS rounds beginning with round one produces the overall response rate through the last MEPS round specified.

The overall response rate for the combined sample of Panels 10 and 11 for 2006 was obtained by computing the products of the relative sample sizes and the corresponding overall panel response rates and then summing the two products. Panel 11 represents about 53 percent of the combined sample size while Panel 10 represents the remaining 47 percent. Thus, the combined response rate has been computed as .53 times the overall Panel 11 response rate through Round 3 plus .47 times the overall Panel 10 response rate through Round 5.

For MEPS Panel 11, Round 1 9,434 households were fielded in 2006 (row C of Table 3.1), a nationally representative subsample of the households responding to the 2005 National Health Interview Survey (NHIS).

Table 3.1 shows the number of RUs eligible for interviewing in each Round of Panel 11 as well as the number of RUs completing the MEPS interview. Computing the individual Round "conditional" response rates as described in section 3.2.1 and then taking the product of these three response rates and the factor 87.26 (the percentage of the NHIS sampled households designated for use in selecting a sample of households for MEPS) yields an overall response rate of 58.19 percent for Panel 11 through Round 3.

For MEPS Panel 10, 8,505 households were fielded in 2005 (as indicated in Row C of Table 3.1), a nationally representative subsample of the households responding to the 2004 National Health Interview Survey (NHIS).

Table 3.1 shows the number of RUs eligible for interviewing and the number completing the interview for all five rounds of Panel 10. The overall response rate for Panel 10 has been computed in a similar fashion to that of Panel 11 but covering all five rounds of MEPS interviewing as well the factor representing the percentage of NHIS sampled households eligible for MEPS. The overall response rate for Panel 10 through Round 5 is 58.49 percent.

A combined response rate for the survey respondents in this data set is obtained by taking a weighted average of the panel specific response rates. The Panel 10 response rate was weighted by a factor of .47 and that of Panel 11 was weighted by a factor of .53, reflecting approximately the distribution of the overall sample between the two panels. The resulting combined response rate for the combined panels has been computed as (.47 x 58.49) plus (.53 x 58.19) or 58.33 percent (as shown in Table 3.1).

Oversampling is a feature of the MEPS sample design, helping to increase the precision of estimates for some subgroups of interest. Before going into details related to MEPS, the concept of oversampling will be discussed.

In a sample where all persons in a population are selected with the same probability and survey coverage of the population is high, the sample distribution is expected to be proportionate to the population distribution. For example, if Hispanics represent 15 percent of the general population, one would expect roughly 15 percent of the persons sampled to be Hispanic. However, in order to improve the precision of estimates for specific subgroups of a population, one might decide to select samples from those subgroups at higher rates than the remainder of the population. Thus, one might select Hispanics at twice the rate (i.e., at double the probability) of persons not oversampled. As a result, an oversampled subgroup comprises a higher proportion of the sample than it represents in the general population. Sample weights ensure that population estimates are not distorted by a disproportionate contribution from oversampled subgroups (i.e., base sample weights for oversampled groups will be smaller than for the portion of the population not oversampled). For example, if a subgroup is sampled at roughly twice the rate of sample selection for the remainder of the population not oversampled, members of the oversampled subgroup will receive base or initial sample weights (prior to nonresponse or poststratification adjustments) that are roughly half the size of the group "not oversampled".

As mentioned above, oversampling is implemented to increase the sample sizes and thus improve the precision of survey estimates for particular subgroups of the population. The "cost" of oversampling is that the precision of estimates for the general population and subgroups not oversampled will be reduced to some extent compared to the precision one could have achieved if the same overall sample size were selected without any oversampling.

The oversampling of Hispanic and Black households for the NHIS carries over to MEPS through the set of NHIS responding households eligible for sample selection for MEPS. In the NHIS, Hispanic households were oversampled at a rate of roughly 2 to 1. That is, the probability of selecting a Hispanic household for participation in the NHIS was roughly twice that for households in the general population that were not oversampled. The oversampling rate for Black households was roughly 1.5 to 1.

For both the MEPS Panel 10 sample and the MEPS Panel 11 sample, the NHIS responding households eligible for MEPS that contained either Asians or families predicted to have an income under 200 percent of the poverty level (based on a statistical model) were sampled with certainty. In addition, households containing Blacks who were not among those households selected with certainty were also oversampled. The sampling rate for the Black stratum was the same for both Panels: roughly three-quarters for each panel. About 56 percent of all remaining NHIS households eligible for MEPS were sampled for Panel 11. The rate was about 53 percent for "remaining" NHIS households for Panel 10.. To accomplish this, systematic samples were selected from each stratum formed from the MEPS-eligible households, as described above. In summary, households containing Hispanics, Blacks, Asians, and those predicted to be under 200 percent of poverty were oversampled for both Panels 10 and 11.

There is a single person-level weight variable called PERWT06P. However, care should be taken in its application as it permits both "point-in-time" and "range of time" estimates, depending on the variables used to define the set of persons of interest for analysis. A person-level weight was assigned to each key, inscope person who responded to MEPS for the full period of time that he or she was inscope during the MEPS (recall that a person is inscope whenever he or she is a member of the civilian, noninstitutionalized portion of the U.S. population). Since Panel 10 began in 2005, persons were required to provide data while inscope for both 2005 and 2006. Since Panel 11 persons began in 2006, the requirement only pertains to 2006.

The data in this file can be used to develop estimates on persons in the civilian, noninstitutionalized population at any time during 2006 and for the slightly smaller population of persons in the civilian, noninstitutionalized population on December 31, 2006. To obtain a cross-sectional (point-in-time) estimate for inscope persons living in the country on December 31, 2006, the analysis should be restricted to cases where INSC1231=1 (the person is inscope on December 31, 2006). The weight variable PERWT06P must be applied to the analytic variable(s) of interest to obtain either type of national estimate. Table 3.2 contains a summary of cases to include and sample sizes for the two populations described above.

Table 3.2 Identifying Populations of Interest at the Person Level and Corresponding Sample Sizes

The person-level weight PERWT06P was developed in three stages. The person-level weight for Panel 11 was created, including both an adjustment for nonresponse over time and raking, controlling to several sets of marginal control totals reflecting Current Population Survey (CPS) population estimates based on five different variables. The person-level weight for Panel 10 was created, also including an adjustment for nonresponse over time and raking, controlling to CPS population estimates based on the same five variables. A composite weight was formed from the Panel 10 and Panel 11 weights by multiplying the Panel weights by factors corresponding to the relative sample size of the two panels. Then a final raking was undertaken on this composite weight variable, again based on the same five variables used previously.

The person-level weight for MEPS Panel 10 was developed using the 2005 full-year weight for an individual as a "base" weight for survey participants present in 2005. For key, inscope respondents who joined an RU some time in 2006 after being out-of-scope in 2005, the "base" weight was taken to be the 2005 family weight associated with the family the person joined. The weighting process included an adjustment for nonresponse over Rounds 4 and 5 as well as raking to population control totals for December 2006 for key, responding persons inscope on December 31, 2006. These control totals were derived by scaling back the population distribution obtained from the March 2007 CPS to reflect the December 31, 2006 estimated population total (estimated based on Census projections for January 1, 2007). Variables used for person-level raking included: Census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic, Black but non-Hispanic, Asian, and other); sex; and age. (Poverty status is not included in this version of the MEPS full year database because of the time required to process the income data collected and then assign persons to a poverty status category). Key responding persons not inscope on December 31, 2006 but inscope earlier in the year retained, as their final Panel 10 weight, the weight after the nonresponse adjustment.

The person-level weight for MEPS Panel 11 was developed using the MEPS Round 1 person-level weight as a "base" weight. For key, inscope respondents who joined an RU after Round 1, the Round 1 family weight served as a "base" weight. The weighting process included an adjustment for nonresponse over the remaining data collection rounds in 2006 as well as raking to the same population control figures for December 2006 used for the MEPS Panel 10 weights for key, responding persons inscope on December 31, 2006. The same five variables employed for Panel 10 raking (census region, MSA status, race/ethnicity, sex, and age) were also used for Panel 11 raking. As with Panel 10, Panel 11 key, responding persons not inscope on December 31, 2006 but inscope earlier in the year retained the weight after nonresponse adjustment as their final Panel 11 weight.

Note that the MEPS Round 1 weights for both panels incorporated the following components: the original household probability of selection for the NHIS; a factor representing the proportion of the 16 NHIS panel-quarter combinations eligible for MEPS; the oversampling of certain subgroups for MEPS among the NHIS household respondents eligible for MEPS; ratio-adjustment to NHIS-based national population estimates at the household (occupied DU) level; adjustment for nonresponse at the DU-level for Round 1; and poststratification to U.S. civilian noninstitutionalized population estimates at the family and person level obtained from the corresponding March CPS data bases.

Beginning with the Full Year 2002 files, "raking" has been employed for the "Full Year" MEPS weighting to calibrate surveys weights to match designated population control totals, replacing the poststratification process previously employed. Raking is a commonly used process for adjusting survey weights so that estimates of subpopulation totals match more stable figures available from independent sources. It can be thought of as multi-dimensional poststratification that requires an iterative solution. Survey weights are poststratified to several sets of control figures (dimensions) in a sequential and continuous fashion until convergence is achieved. Convergence is the state where survey weights satisfy the criteria that the sums of the survey weights for the subgroups represented by the various dimensions are simultaneously within a specified distance of the corresponding control figures (for example, within 1, 10, 100, 500, etc. of the control totals). For example, if one dimension in a raking effort was sex by MSA status and the specified distance was 10, then, after convergence has been achieved, the sum of the survey weights for males in MSA areas would be within 10 of the control figure for males in MSA areas, etc.

Variables used in the raking of the person-level weights to control totals derived from CPS data included: census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic, Black but non-Hispanic, Asian, and other); sex, and age. Persons included in the raking process were those inscope on December 31, 2006. In addition, the weights of some persons out-of-scope on December 31, 2006 were poststratified. Specifically, the weights of persons out-of-scope on December 31, 2006 that were inscope some time during the year and also entered a nursing home during the year were poststratified to a corresponding control total obtained from the 1996 MEPS Nursing Home Component. The weights of persons who died while inscope during 2006 were poststratified to corresponding estimates derived using data obtained from the Medicare Current Beneficiary Survey (MCBS) and Vital Statistics information provided by the National Center for Health Statistics (NCHS). Separate control totals were developed for the "65 and older" and "under 65" civilian, noninstitutionalized decedent populations.

Overall, the weighted population estimate for the civilian, noninstitutionalized population over the course of the year (PERWT06P>0) is 299,267,035 (see Table 3.3). The weighted population for the population that was in-scope for the survey on December 31, 2006 (PERWT06P>0 and INSC1231=1) is 295,668,762.

Beginning with the 2001 Full Year data, MEPS transitioned to 2000 census-based population estimates for poststratification and raking. Prior to 2001, 1990-census-based estimates were used. In addition, MEPS population estimates have undergone some "discontinuities", due to adjustments made to the 2003 CPS estimates (CPS is the source of the control figures used for raking and poststratification in MEPS). More specifically, MEPS estimates for the civilian, noninstitutionalized population from the full year 2001 public use files compared to those from previous years show a sizeable increase in population in 2001. In previous years the percentage increase had been slightly under one percent, while between the 2000 and 2001 MEPS population estimates it was roughly two percent. The MEPS file for full year 2001 was the first where CPS figures reflected 2000 Census figures instead of projections from figures obtained from the 1990 Census. The projections were somewhat low compared to 2000 Census figures. Some subgroups were particularly affected. For example, the CPS figures reflecting 2000 Census figures provide population estimates for Hispanics that are roughly 8 percent higher than previous projections suggested. For the full year 2003 files there was another discontinuity. The March, 2003 CPS database, the basis of the MEPS full year 2002 control figures, experienced a one time population adjustment of roughly 941,000, reflecting current information and research on net migration. This had a large impact on the Hispanic population (roughly a 1.7 percent increase), a minor impact on the white population (a .4 percent increase), and no change at all in Black population estimates.

For more information about these recent changes in CPS population estimates, see "Revisions to the Current Population Survey Effective in January 2003" in the January 2003 issue of the monthly Labor Review (authored by Mary Bowler, Randy E. Ilg, Stephen Miller, Ed Robison, and Anne Polivka, all at the Bureau of Labor Statistics). Recent changes in the definition of racial categories are also noted in this report.

The target population associated with this MEPS database is the 2006 U.S. civilian, noninstitutionalized population. However, the MEPS sampled households are a subsample of the NHIS households interviewed in 2004 (Panel 10) and 2005 (Panel 11). New households created after the NHIS interviews for the respective Panels and consisting exclusively of persons who entered the target population after 2004 (Panel 10) or after 2005 (Panel 11) are not covered by MEPS. Neither are previously out-of-scope persons who join an existing household but are unrelated to the current household residents. Persons not covered by a given MEPS panel thus include some members of the following groups: immigrants; persons leaving the military; U.S. citizens returning from residence in another country; and persons leaving institutions. Those not covered represent only a small proportion of the MEPS target population.

Due to relatively limited opportunities for family-level analysis with the data on this file, family weights are not included on this file. However, family weights will be created for the Full Year 2006 MEPS Public Use File where expenditure and income data are provided. Nevertheless, records for those persons who will have a positive family weight but not a positive person weight have been placed on this Public Use File to maintain consistency in terms of file structure with the upcoming Public Use File with expenditure and income data. Those will be the only records without a positive person weight appearing on this file.

For analytic purposes, a single person-level weight variable, SAQWT06P, has been provided for use with the data obtained from the Self-Administered Questionnaire (SAQ). This questionnaire was administered in Panel 11, Round 2 and Panel 10, Round 4 and was to be completed by each adult (person aged 18 or older) in the family. Thus, the target population for the SAQ is adults in the civilian, noninstitutionalized population at the time data were collected for Rounds 2/4.

The weight variable was developed by first adjusting for questionnaire non-response. Variables used in the nonresponse adjustment process were region, MSA status, family size, marital status, level of education, health status, health insurance status, age, sex and race/ethnicity. Then the weights were raked to Current Population Survey (CPS) estimates corresponding to December 2006 (the same source of control figures used for the full year person weights). The variables used to form control figures were region, MSA status, age, sex, and race/ethnicity, as were used for the full year person weights. The only difference was that age categories were developed after excluding ages under 18, since only adults were eligible for the SAQ.

In all, there were 20,832 persons assigned a SAQ weight with the sum of the weights being 221,664,474 (an estimate of the civilian, noninstitutionalized population aged 18 or older at the time the SAQ was administered).

The Panel 10 response rate for the 2006 SAQ was 91.9 percent, while the Panel 11 response rate for the 2006 SAQ was 90.3 percent. Pooled response rates for the survey respondents have been computed by taking a weighted average of the panel-specific response rates, where the weights were the relative proportion of persons with sample weights associated with each panel (a value of .47 was associated with Panel 10, and a value of .53 was associated with Panel 11). The pooled response rate for the combined panels for the 2006 SAQ is 91.0 percent.

A person-level weight, DIABW06P, was developed for use with the data obtained from the Diabetes Care Survey (DCS). This weight was assigned to each person with a SAQ weight who was also classified as having diabetes (thus, no one aged 17 or under receives a DCS weight).

To determine this classification, the RU respondent was asked to identify any family member in the residence having diabetes. Then, those identified with diabetes were asked if a doctor had ever indicated that the person had diabetes. Those who responded affirmatively to that question and who also had a SAQ weight were assigned a DCS weight.

In all, 1,803 people were assigned a DCS weight (DIABW06P>0). The sum of the DCS weights is 17,934,627, an estimate of the adult population self-reporting as having been diagnosed with diabetes as identified by the two step process described above. This estimate likely understates the number of persons with diabetes because occasionally a family member with diabetes may not have been identified by the RU respondent. In addition, persons who joined an RU in Round 3 of Panel 11 or Round 5 of Panel 10, some of whom may have diabetes, were not eligible for the SAQ and thus not eligible for a DCS weight.

The Panel 10 response rate for the 2006 DCS was 89.5 percent. The Panel 11 response rate for the 2006 DCS was 86.7 percent. The pooled response rate for the combined panels for the DCS is 88.0 percent. The pooled response rate is a weighted average for the two panels, reflecting their relative sample sizes (roughly 47 percent of the respondents are from Panel 10, the remaining 53 percent from Panel 11).

MEPS has a complex sample design. To obtain estimates of variability (such as the standard error of sample estimates or corresponding confidence intervals) for MEPS estimates, analysts need to take into account the complex sample design of MEPS for both person-level and family-level analyses. Several methodologies have been developed for estimating standard errors for surveys with a complex sample design, including the Taylor-series linearization method, balanced repeated replication, and jackknife replication. Various software packages provide analysts with the capability of implementing these methodologies. Replicate weights have not been developed for the MEPS data. Instead, the variables needed to calculate appropriate standard errors based on the Taylor-series linearization method are included on this file as well as all other MEPS public use files. Software packages that permit the use of the Taylor-series linearization method include SUDAAN, Stata, SAS (version 8.2 and higher), and SPSS (version 12.0 and higher). For complete information on the capabilities of each package, analysts should refer to the corresponding software user documentation.

Using the Taylor-series linearization method, variance estimation strata and the variance estimation PSUs within these strata must be specified. The variance strata variable is named VARSTR, while the variance PSU variable is named VARPSU. Specifying a "with replacement" design in a computer software package, such as SUDAAN, provides standard errors appropriate for assessing the variability of MEPS survey estimates. It should be noted that the number of degrees of freedom associated with estimates of variability indicated by such a package may not appropriately reflect the actual number available. For MEPS sample estimates for characteristics generally distributed throughout the country (and thus the sample PSUs), one can expect at least 100 degrees of freedom for the 2006 full year data associated with the corresponding estimates of variance.

Prior to 2002, MEPS variance strata and PSUs were developed independently from year to year, and the last two characters of the strata and PSU variable names denoted the year. However, beginning with the 2002 Point-in-Time PUF, the variance strata and PSUs were developed to be compatible with MEPS data associated with the NHIS sample design used through 2006. Such data can be pooled and the variance strata and PSU variables provided can be used without modification for variance estimation purposes for estimates covering multiple years of data. There are 203 variance estimation strata, each stratum with either two or three variance estimation PSUs.

Note: A new NHIS sample design is being implemented beginning in 2006. As a result, the MEPS variance estimation structure will be modified for MEPS data collected in 2007 and beyond.

For person level analyses not involving variables from the SAQ or DCS, PERWT06P should always be used.

For person-level analysis involving variables from the SAQ but not the DCS, the SAQWT06P should be used. For example, if examining access to care or quality of care variables from the SAQ by social-demographics, health status, or health insurance, SAQWT06P is the appropriate weight even though person level socio-demographic, health status, and health insurance variables are part of the core person level questionnaire. Whenever data from the Diabetes Care Survey (DCS) are used, alone or in conjunction with data from other questionnaires, the weight variable DIABW06P should be used for those eligible to provide DCS data.

MEPS began in 1996 and the utility of the survey for analyzing health care trends expands with each additional year of data. However, it is important to consider a variety of factors when examining trends over time using MEPS. Statistical significance tests should be conducted to assess the likelihood that observed trends are not attributable to sampling variation. The length of time being analyzed should also be considered. In particular, large shifts in survey estimates over short periods of time (e.g. from one year to the next) that are statistically significant should be interpreted with caution, unless they are attributable to known factors such as changes in public policy, economic conditions, or MEPS survey methodology. Looking at changes over longer periods of time can provide a more complete picture of underlying trends. Analysts of MEPS data may wish to consider using techniques to evaluate, smooth, or stabilize estimates of trends. Such techniques include comparing pooled time periods (e.g. 1996-97 versus 2005-06), working with moving averages, or using modeling techniques with several consecutive years of MEPS data to test the fit of specified patterns over time. Finally, researchers should be aware of the impact of multiple comparisons on Type I error (i.e., the chance of declaring an observed difference to be statistically significant when there is no difference in the population parameters). Performing numerous statistical significance tests increases the likelihood of a Type I error.
