This two-volume handbook presents the contemporary cognitive behavioral scholarship that defines the field today. Cognitive behavioral therapy (CBT) is a psychological treatment that focuses on shifting unhelpful thinking or behavior patterns to more adaptive thinking or behavior patterns. An extensive body of empirical research confirms that CBT is highly efficacious in treating depression, anxiety disorders, alcohol and drug use problems, marital problems, eating disorders, and severe mental illness. Edited by renowned CBT scholar and practitioner Amy Wenzel, this handbook includes a comprehensive examination of contemporary CBT. Volume 1 provides a historical and theoretical overview of CBT, summarizes the empirical support for the approach, describes the main strategies and techniques, and summarizes an array of CBT treatment packages. Volume 2 evaluates the application of CBT to specific clinical conditions, modalities and settings, and diverse populations. With its in-depth coverage, up-to-date research, and rich clinical examples, this handbook is an invaluable resource for all clinicians who offer CBT.
