“Dr. Nancy Petry shares the wisdom gleaned from her extensive experience in developing, testing, and training innovative CM interventions for substance users. She demonstrates how to develop a CM program and provides helpful examples of patient-clinician dialogues and supervision methods. This outstanding resource is the first of its kind.” - Maxine Stitzer, Johns Hopkins University School of Medicine, Maryland, USA“This book represents an important step towards proper dissemination of Contingency Management. Organizations and programs interested in implementation will find it useful for the purposes of designing CM protocols, as well as for training clinical staff in the basic tenets of CM. The book not only offers practical 'how to' information, but also provides step-by-step guides and worksheets that can be directly applied to clinical practice.” - Lissa Dutra, Boston Institute for Psychotherapy, USA “Dr. Petry’s latest contribution to the literature on Contingency Management is both scholarly and pragmatic. It is highly recommended for clinicians and trainees in the mental health and substance abuse fields, who will learn the state of the art of evidence-based CM as well as how to practically implement this approach in a variety of clinical situations for different sub-populations.” - Yifrah Kaminer, University of Connecticut Health Center, USA
