What is SAMHDA?
The Center for Behavioral Health Statistics and Quality (CBHSQ), Substance Abuse & Mental Health Services Administration (SAMHSA) has primary responsibility for the collection, analysis, and dissemination of SAMHSA's behavioral health data.
CBHSQ promotes the access and use of the nation's substance abuse and mental health research data through the Substance Abuse and Mental Health Data Archive (SAMHDA). SAMHDA provides public-use data files, file documentation, and access to restricted-use data files to support a better understanding of this critical area of public health. The University of Michigan, Inter-University Consortium for Political and Social Research (ICPSR), is under contract to CBHSQ to disseminate data, and maintain the SAMHDA Web site and bibliography of publications.
