Community-based addiction treatment centers have seen a dramatic rise in the number of multi-problem clients with diverse experiences such as past trauma, incarceration, and high risks of relapse. Because the largest and fastest growing segment of the community-based addiction treatment population includes those who are mandated, this book addresses the task of 'making mandated addiction treatment work.' It is a practical guide for how to adapt and integrate evidence-based addiction treatments to create a unified treatment model, and a valuable tool for those in public health, criminal justice, and social welfare services.
