ADSS Overview

The Alcohol and Drug Services Study (ADSS)  is a nationally representative survey of substance abuse treatment facilities and clients. The data were collected to estimate the client length of stay and the costs of treatment as well as to describe the post-treatment status of clients.  ADSS builds upon the 1990 Drug Services Research Survey (DSRS) and the Services Research Outcome Study (SROS) with a more complete sampling frame, an enhanced sampling design, and more detailed measures of the level of treatment services provided, the costs of treatment, and clients in treatment.

ADSS consists of three phases: 

Phase I:

  • a facility-based telephone interview with a representative sample of about 2,400 substance abuse treatment facilities

Phase II:

  • an on-site facility survey with a subsample of 280 treatment facilities; and 
  • a record-based survey of clients where client-level information was abstracted for a sample of over 5,000 client records and a comparison group. 

Phase III:  

  • follow-up personal interviews with the Phase II sample of clients and a comparison group to determine post-treatment status in terms of substance use, economic status, criminal justice status, and further substance abuse treatment episodes. Urine testing was conducted to validate self-report of drug use

Note to Users

Note to Users:

The Alcohol and Drug Services Study (ADSS) provides an opportunity for researchers to explore and analyze a unique data base that can provide new insights into the relationships between substance abuse treatment clients and facilities.  

Great care has been taken by staff of SAMHSA’s Office of Applied Studies (OAS) and its contractors to create ADSS public-use data sets that are as complete as possible and consistent with the statutory requirements to maintain and safeguard the confidentiality of individual and institutional records. These requirements have been balanced against the important need to make the ADSS data files available in a timely fashion and to facilitate electronic download and analysis by users.  

Accompanying these files is documentation that has been compiled into a series of ADSS reports.  Several of these ADSS reports are being released as working documents to minimize delay.  Every effort has been made to ensure the accuracy of the working documents but errors may still remain.  We request that you bring any errors to the attention of OAS staff.   Click for sending comments or requesting printed reports
