Welcome to the National Substance Use and Mental Health Services Survey (N‑SUMHSS) information website. This online resource center includes tools to help facilities complete the N‑SUMHSS. You’ll find useful links on the left, and practical survey tips and tutorials, below.

The N‑SUMHSS is a voluntary annual survey of all active substance use and mental health facilities in the United States and its jurisdictions. The survey gathers information about the services that treatment facilities provide and summary‑level information about the clients served.

The N‑SUMHSS is being conducted by ICF on behalf of the Substance Abuse and Mental Health Services Administration (SAMHSA).

Two Surveys, Now One

The N‑SUMHSS 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 into one survey. If your facility participated in the N‑SSATS and/or the N‑MHSS before, you will find the questions and layout of the N‑SUMHSS very similar.

Your Participation Counts

Participation is voluntary, but your response is important so that your facility and the populations you serve are represented.

Only N‑SUMHSS participants have the option of being listed in SAMHSA’s online Behavioral Health Treatment Services Locator (https://findtreatment.samhsa.gov). Being featured on the locator may help you reach potential clients in populations you were not reaching before.

Your Data Matters

The N‑SUMHSS is the most comprehensive source of substance use and mental health treatment data in the country. SAMHSA, other Federal, state, and local agencies, and behavioral health care professionals use these data to understand treatment availability and identify gaps in our nation’s treatment services.
