Graphing Multi-Year Analyses of TEDS

The DASIS Report:  Graphing Multi-Year Analyses of TEDS

SAMHSA's Treatment Episode Data Set (TEDS) public use files are available from SAMHSA's Substance Abuse and Mental Health Data Archive (SAMHDA).  The 1992-2000 TEDS files, as well as a concatenated file for 1995-2000, are available from the archive.

The TEDS data contains 9.6 million records and is useful for analyzing changes over time in treatment admissions and primary drugs of abuse.  This report illustrates how trends in admissions from 1995 to 2000 can be analyzed in the four Census regions of the country, using heroin as a primary, secondary, or tertiary substance of abuse as an example. Using SAMHSA's online data analysis system, you can get percentages of substance abuse treatment admissions in each region, trends from 1995 to 2000,  statistical testing and a graph of the results.

For further information on how the TEDS data set can be used to make geographic comparisons, see The DASIS Report:  Analyzing Geographic Areas Within TEDS.

The Substance Abuse and Mental Health Data Archive (SAMHDA) online data analysis system is provided by the Office of Applied Studies within the Substance Abuse and Mental Health Services Administration (SAMHSA).  In addition to the Treatment Episode Data Set (TEDS), SAMHDA contains over 80 studies on substance abuse that are available for online data analysis.
