Sample Information
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.
