Data We Collect

SAMHSA’s CBHSQ is a designated statistical agency under the Census Bureau. The Center for Behavioral Health Statistics and Quality (CBHSQ) is the leading source of behavioral health data in the United States. Behavioral health data collected includes:

  • Prevalence of mental illness and substance use disorders
  • Behavioral health service provision and use
  • Evaluation data

This data helps researchers, public health officials, and policymakers to understand and solve issues.

  • The National Survey on Drug Use and Health (NSDUH) is a primary source of data on behavioral health among U.S. households. It is used to identify prevalence, trends, and correlates among behavioral health related issues at national and state levels.
  • The Treatment Episode Data Set (TEDS) is a national data system of admissions and discharges at substance abuse treatment facilities. It contains demographic, substance use, and visit related information.
  • The National Mental Health Services Survey (N-MHSS) collects data from mental health treatment facilities in the United States. It helps SAMHSA and state and local governments analyze treatment service and maintain the Behavioral Health Treatment Services Locator.
  • The National Survey of Substance Abuse Treatment Services compliments the N-MHSS and collects data from substance use treatment facilities in the United States. It helps SAMHSA and state and local governments analyze treatment services and maintain the Behavioral Health Treatment Services Locator.
  • SAMHSA is re-establishing the Drug Abuse Warning Network (DAWN), a nationwide public health surveillance system that will improve emergency department (ED) monitoring of substance use crises, including those related to opioids. Hospital participation will continue to be voluntary. Data abstraction will begin in mid-2019 with a group of 25 hospitals, and will grow to 50 hospitals in DAWN’s second year.
  • The Uniform Reporting System (URS) is comprised of 21 Excel tables that are developed by the federal government in consultation with State Mental Health Agencies (SMHAs).
  • The Mental Health Client-Level Data system works with states to collect data on demographic, clinical, and outcome characteristics of individuals receiving mental health treatment services. It helps SAMHSA and State level agencies understand the mental health needs and available services.
