National Mental Health Services Survey (N-MHSS)

The National Substance Use and Mental Health Service Survey (N-SUMHSS) replaced the National Survey of Substance Abuse Treatment Services (N-SSATS) and the National Mental Health Services Survey (N-MHSS) in 2021 by combining questions for substance use and mental health facilities.
