National Mental Health Services Survey 2018 (N-MHSS-2018)

Parent Series Details:

The National Mental Health Services Survey (N-MHSS) is an annual survey designed to collect statistical information on the services and characteristics of all known mental health treatment facilities within the 50 States, the District of Columbia, and the U.S. territories. In every other year, beginning in 2014, the survey also collects statistical information on the numbers and demographic characteristics of persons served in these treatment facilities as of a specified survey reference date.

The N-MHSS is the only source of national and State-level data on the mental health service delivery system reported by both publicly-operated and privately-operated specialty mental health treatment facilities, including: public and private psychiatric hospitals; non-federal general hospitals with separate psychiatric units; U.S. Department of Veterans Affairs medical centers; residential treatment centers for children and for adults; community mental health centers; outpatient or day treatment or partial hospitalization mental health facilities; and multi-setting (non-hospital) mental health facilities.

The N-MHSS complements the information collected through SAMHSA's survey of substance abuse treatment facilities, the National Survey of Substance Abuse Treatment Services (N-SSATS). Treatment facility Information from the N-MHSS is used to populate the mental health component of SAMHSA's online Behavioral Health Treatment Services Locator.

 


Study Details:

The 2018 National Mental Health Services Survey (N-MHSS) was conducted from March 2018 through November 2018. The N-MHSS collects information from all known facilities in the United States, both public and private, that provide mental health treatment services to people with mental illness. The Center for Behavioral Health Statistics and Quality (CBHSQ) of the Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Health and Human Services, plans and directs the N-MHSS.

The N-MHSS provides a mechanism for quantifying the dynamic character and composition of the U.S. mental health treatment delivery system. It 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 care facilities. The N-MHSS is designed to collect data on the location, characteristics, and utilization of organized mental health treatment service providers for facilities within the scope of the survey throughout the 50 states, the District of Columbia, and other jurisdictions. The N-MHSS complements, but does not duplicate, the information collected through SAMHSA’s survey of substance abuse treatment facilities, the National Survey of Substance Abuse Treatment Services (N-SSATS).

The objective of the N-MHSS is to collect data that can be used to:

  • assist SAMHSA and state and local governments in assessing the nature and extent of services provided in state-funded, state-operated, private non-profit, and for-profit mental health treatment facilities, and in forecasting mental health treatment resource requirements;
  • update SAMHSA’s Inventory of Behavioral Health Services (I-BHS), an inventory of all known mental health and substance abuse treatment facilities in the United States, which can be used as a frame for future surveys of these facilities;
  • describe the nature and scope of mental health treatment services and conductcomparative analyses for the nation and states; and
  • update the information in the mental health component of SAMHSA’s online Behavioral Health Treatment Services Locator, which includes a searchable database of public and private facilities for the provision of mental health treatment. The Locator is available at: https://findtreatment.samhsa.gov

Study Scope

Time period: 
2018
Collection date: 
March 26, 2018 through November 30, 2018
Geographic coverage : 
United States
Data types: 
survey data
Universe: 
The survey universe for the 2018 N-MHSS survey universe included 14,159 facilities across the United States and other jurisdictions.
Notes: 

As with any data collection effort, certain procedural considerations and data limitations must be taken into account when interpreting data fromthe 2018 N-MHSS. Some general issues are listed below. Considerations and limitations of specific data items are discussed where the data are presented.

  • The N-MHSS is a voluntary survey and while every effort is made to obtain responses from all known mental health treatment facilities within the scope of the survey, some facilities did not respond. There was no adjustment for the 10 percent facility non-response.
  • The N-MHSS is a point-prevalence survey. It provides information on the mental health treatment system and its clients as of a pre-selected reference date (April 30, 2018). Client counts do not represent annual totals. Rather, the N-MHSS provides a snapshot of mental health treatment facilities and clients on an average day or month.
  • Multiple responses were allowed for certain questionnaire items (e.g., services provided in non-English languages and types of payment or insurance accepted for mental health treatment services).
Subject Terms:
