TDMHSAS Data and Reports

The Office of Research brings together data in order to evaluate program effectiveness; collect and provide performance-based outcome measures to funders; identify trends in mental health and substance abuse; and provide direction for programming decisions.

The resources below allow users to access Tennessee-specific data. These analyses and reports serve as a tool to inform community leaders, policy makers, service providers, and the general public on relevant study areas and guide data-driven decisions regarding mental health and substance abuse.

TDMHSAS Needs Assessment

The purpose of the Needs Assessment Process is to create an evidence-based method (1) for TDMHSAS Statewide and Regional Planning and Policy Councils to influence the design of the mental health and substance abuse system by identifying each region's assets and needs; and (2) for TDMHSAS to target limited state resources to more effectively and efficiently meet the identified needs.
