National Mental Health Services Survey (N-MHSS)
N-MHSS is the only source of national- and state-level data on the mental health services delivery system reported by both publicly and privately operated specialty mental health treatment facilities. They include:
- Public and private psychiatric hospitals
- Nonfederal general hospitals with separate psychiatric units
- U.S. Department of Veterans Affairs medical centers
- Residential treatment centers for children and adults
- Community mental health centers
- Outpatient, day treatment, or partial hospitalization mental health facilities
- Multi-setting (non-hospital) mental health facilities
N-MHSS complements the information gathered through the National Survey of Substance Abuse Treatment Services (N-SSATS).
Where Do the Data Come From?
N-MHSS is an annual survey to collect information on the location, organization, structure, services, and utilization of mental health treatment facilities. It is designed to collect statistical information on all known mental health treatment facilities in the United States. This includes the 50 states, the District of Columbia, and all U.S. territories. Every other year, starting in 2014, N-MHSS also collects information on the numbers and demographics of persons served in these treatment centers.
