Mental Health and Substance Abuse

The work of The Lewin Group is grounded in an understanding of the multiple systems and interests in the complex and dynamic behavioral health environment.

We help state and federal agencies, foundations, associations, and providers to plan strategically, design and manage effective initiatives, and evaluate the impact of policy and program change. Further, we help clients develop solutions that serve consumers while achieving public policy goals, and we routinely provide public and private sector clients with data-driven analyses and consulting.

A Resource Guide for State Officials: Implementing and Financing Assertive Community Treatment Programs

The Lewin Group prepared a field-tested and practice-proven resource guide for decision makers in state governments. It provides practical, experience-based information about strategies for implementing ACT programs to assist individuals who have severe and persistent mental illness. Additionally, the resource guide presents a broad overview of ACT program concepts and issues, including:

  • Factors that help or hurt program implementation, such as financing structures, consumer issues, and common concerns
  • A budget simulation model that provides a cost forecasting method to enable states to project costs based on specific population and program design scenarios
  • A companion literature review that offers details regarding assertions about ACT model requirements and the evidence base of research supporting the ACT program

"Throughout the engagement, Lewin consultants listened to us and delivered superb analyses and thoughtful guidance–not canned solutions.
