National Survey of Substance Abuse Treatment Services


The National Survey of Substance Abuse Treatment Services (N-SSATS) is designed to collect information from all facilities in the United States, both public and private, that provide substance abuse treatment. N-SSATS provides the mechanism for quantifying the dynamic character and composition of the U.S. substance abuse treatment delivery system. The objectives of N-SSATS are to collect multipurpose data that can be used to assist the Substanve Abuse and Mental Health Services Administration (SAMHSA) and state and local governments in assessing the nature and extent of services provided and in forecasting treatment resource requirements, to update SAMHSA's Inventory of Substance Abuse Treatment Services (I-SATS), to analyze general treatment services trends, and to generate the National Directory of Drug and Alcohol Abuse Treatment Programs and its online equivalent, the Substance Abuse Treatment Facility Locator.

Data Years Available: 
Mode of Collection: 
Mail survey with mail, telephone, and web-based response options.
Selected Content: 
Topics include ownership, services offered, primary focus (substance abuse, mental health, general health, etc.), hotline operation, methadone/buprenorphine dispensing, counseling and therapeutic approaches, type of treatment provided, number of clients, number of beds, types of payment accepted, sliding fee scale, special programs offered, facility accreditation and licensure/certification, and managed care agreements.
Population Covered: 

The facility universe included all active treatment facilities in SAMHSA's Inventory of Substance Abuse Treatment Services (I-SATS). The Inventory includes facilities that are licensed, certified, or otherwise approved by state substance abuse agencies to provide substance abuse treatment. In addition, a group of facilities that state agencies, for a variety of reasons, do not license or certify are in I-SATS. (Many of these are private, for-profit, small group practices, or hospital-based programs.) Questionnaires were mailed to all facilities believed to offer substance abuse treatment services.

Response Rates and Sample Size: 

Of the 16,773 facilities surveyed, 9.4% were found to be ineligible because they had closed or did not provide substance abuse or detoxification treatment. Of the remaining 15, 188 facilities, 94.5% (14,359) completed the survey. Of these, 408 were deemed to be out of scope and an additional 303 facilities reported client counts included in other facilities' counts. Thus, the final sample size was 13,648 (89.9%).
