Substance Abuse and Mental Health Practice: A Casebook on Co-occurring Disorders provides readers with illuminating, complex cases that shed light on how experienced practitioners think about practice, struggle to resolve practice dilemmas, and make clinical decisions to meet the needs of clients with co-occurring disorders.

The opening chapter presents the Advanced Multiple Systems (AMS) approach, gleaned from the editors' 80 years of combined professional experience and providing readers with a series of guiding practice principles to use while reading the evaluating cases. In following chapters, cases are presented in the form of in-depth narratives. Through an informative storytelling, readers learn about individuals struggling with substance abuse, mental health disorders, racial identity, trauma, and parental rights. In additional chapters, readers are provided with standard assessment forms and challenged to make clinical sense of clients' information and their complex lives. The final chapter reviews best practice methods in the field of co-occurring disorders.

Substance Abuse and Mental Health Practice is part of the Cognella Casebook Series for the Human Services, a collection of textbooks that challenge students to learn through example, build critical competencies, and prepare for effective, vibrant practice.
