Summary:

The Alcohol and Drug Services Study (ADSS) was a national study of substance abuse treatment facilities and clients. The study was designed to develop estimates of the duration and costs of treatment and to describe the post-treatment status of substance abuse clients. ADSS continues and extends upon data collected in the Drug Services Research Survey, 1990: [United States] (ICPSR 3393) and the Services Research Outcome Study, 1995-1996: [United States] (ICPSR 2691) with a more complete sampling frame, an enhanced sampling design, and more detailed measures of treatment services provided, the costs of treatment, and clients in treatment. ADSS was implemented in three phases. In Phase I, a nationally representative sample of treatment facilities was surveyed to assess characteristics of treatment services and clients including treatment type, costs, program capacity, the number of clients served, waiting lists, and services provided to special populations. In Phase II, records were abstracted from a sample of clients in a subsample of Phase I facilities. This phase included four sub-components: (1) the Main Study, an analysis of abstracted records to assess the treatment process and characteristics of discharged clients, (2) the Incentive Study, which assessed the impact of varying financial payments on follow-up interview participation among non-methadone outpatient clients, (3) the In-Treatment Methadone Client study (ITMC), which assessed the treatment process of methadone maintenance, and (4) the comparison study of Early Dropout clients (EDO), which provided a proxy comparison group of records from substance abusers that went untreated. Phase III involved follow-up personal interviews with Phase II clients who could be located. This interview sought to determine post-treatment status in terms of substance use, economic condition, criminal justice involvement, and further substance abuse treatment episodes. Urine testing was conducted to validate self-reported drug use. Drugs included in the survey were alcohol, marijuana, cocaine, crack cocaine, heroin, barbiturates, benzodiazepines, amphetamines, non-prescribed use of prescription medications, abuse of over-the-counter medications, and other drugs. ADSS also included a cost study, which involved obtaining additional financial information from the Phase II facilities. A computerized desktop audit was used in the cost study to conduct consistency and accuracy checks on selected questionnaire data from Phases I and II. Variables were subsequently updated to represent the most accurate data available. Additional analysis variables were then created using combinations of the revised Phase I and II data.
