This book provides a comprehensive review of common adult mental disorders and substance use disorders. The chapters were written by teams of researchers and clinicians, thus providing an integration of empirical findings with clinical experience. Family issues, relapse prevention, the use of self-help groups and co-morbidity are addressed throughout since many patients have multiple disorders and relapse risk is high. In addition, this book integrates considerable information about treatment adherence, and provides the reader with helpful strategies on ways to enhance patient compliance with pharmacotherapy and psychotherapy, as well as strategies for increasing motivation to change. A recovery paradigm is used throughout the book that advocates the importance of helping the patient take an active role in managing his or her disorders.
