National Substance Use and Mental Health Services Survey (N-SUMHSS)

The National Substance Use and Mental Health Services Survey (N-SUMHSS) is a survey of all substance use and mental health treatment facilities, sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA). This is our nation’s most comprehensive national source of data on substance use and mental health treatment facilities. The N-SUMHSS is intended to provide federal, state, and local governments, as well as the behavioral health research community with information about the number and characteristics of public and private substance use and mental health treatment facilities nationwide. This annual survey is crucial to update the information of SAMHSA’s online Behavioral Health Treatment Services Locator, which is available at https://findtreatment.samhsa.gov.

The new N-SUMHSS implemented in 2021 replaces the National Survey of Substance Abuse Treatment Services (N-SSATS) and the National Mental Health Services Survey (N-MHSS) by combining questions for substance use and mental health facilities. N-SSATS and N-MHSS were combined to reduce burden on the facilities, optimize government resources to collect data, and enhance the quality of data collected.
