INTERNALIZING/EXTERNALIZING BEHAVIOR PROBLEMS
NATIONAL LONGITUDINAL STUDY OF ADOLESCENT HEALTH
Measure: Suicide—Audio Computer Assisted Self-Interview
Background
The Suicide Audio Computer Assisted Self-Interview (CASI) is available within the Adolescent In-Home Questionnaire of the National Longitudinal Study of Adolescent Health (Add Health).
Population Assessed
Add Health is a nonexperimental, nationally representative longitudinal study of students in grades 7 through 12 in the United States in the 1994–1995 school year. Data were collected from the youth, their parents, siblings, friends, romantic partners, fellow students, and school administrators through multiple data collection components, including an adolescent in-school survey, adolescent in-home interview, parent in-home interview, and school administrator survey. All instruments were fielded in Wave I. Wave II included an adolescent in-home interview as well as telephone updates from the school administrator. Wave III consisted of only a respondent in-home interview. Available data also include picture vocabulary test scores, in-school friendship network dataset, and information on the geographic location of households within the communities.
In addition to the core sample, the study also oversampled students from several special subgroups, including disabled youth, Chinese, Cuban, and Puerto Rican adolescents, as well as Black youth from high socioeconomic status families. Families were considered to be of high socioeconomic status if at least one parent held a college degree. In addition, the study oversampled adolescents living together within one household. This group is referred to as the “genetic sample” and includes oversamples of twins, half- and step-siblings, and non-related pairs. Some of the adolescents selected from this over-sampled group did not attend one of the original 80 high schools or 52 middle schools, but were recruited because they resided with an adolescent that did attend one of those 132 schools.
Periodicity
All instruments were fielded in Wave I between September 1994 and December 1995. Wave II, fielded approximately 1 year later (during 1996) included an adolescent in-home interview as well as telephone updates from the school administrator. Wave III consisted of only a respondent in-home interview. It was fielded approximately 6 years after Wave II, during 2001–2002.

Procedures for Administration
The Suicide scale was reported by the adolescent. In-home adolescent questionnaires were administered by computer-assisted personal interview. Sensitive information, including this measure of suicidality, was administered by audio CASI. This measure takes about 4 to 5 minutes to administer.
