National Survey of Substance Abuse Treatment Services (N-SSATS)

National Survey of Substance Abuse Treatment Services (N-SSATS), 2020

Before 2021, N-SSATS released yearly public-use files (PUFs). These are full datasets treated with confidentiality protections. The PUFs contain facility data on substance use treatment services. This includes location, organization, structure, services, and utilization. Note, the codebooks may not contain all variables.

In 2021, the National Substance Use and Mental Health Services Survey (N-SUMHSS) replaced the N-SSATS and the N-MHSS. It combines questions for substance use and mental health facilities.

Universe: Facilities across the United States and Jurisdictions, including all active treatment facilities on SAMHSA’s I-BHS and additional facilities provided by state substance use agencies

N-SSATS is a component of SAMHSA’s Behavioral Health Services Information System (BHSIS). The core of BHSIS is the I-BHS, a continuously updated, comprehensive listing of all known substance use treatment facilities and mental health treatment facilities.

Facilities in the I-BHS fall into two categories:

  • Treatment facilities approved by state substance use agencies (16,856 facilities in 2020): Most facilities in the I-BHS are licensed, certified, or otherwise approved by the state substance use agency to provide substance use treatment.
  • Treatment facilities not approved by state substance use agencies (3,070 facilities in 2020): Since the mid-1990s, SAMHSA has worked to make the I-BHS as comprehensive as possible by including treatment facilities that state substance use agencies, for a variety of reasons, do not fund, license, or certify.

As with any data collection effort, limitations must be taken into account when interpreting data from N-SSATS.

  • N-SSATS is a voluntary survey, and while it attempts to obtain responses from all known treatment facilities, some facilities do not respond. The data are not adjusted for facility nonresponse.
  • N-SSATS is a point-prevalence survey. Client counts reported do not represent annual totals. Rather, N-SSATS provides a “snapshot” of substance use treatment facilities and clients on an average day.
  • Multiple responses are allowed for certain variables (e.g., services provided and specialized programs). Tabulations of these variables include the total number of facilities reporting each response.
