This volume describes the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), a research-based approach designed to motivate chronically depressed patients to change and to help them develop needed problem-solving and relationship skills. Presenting clear, step-by-step guidelines for implementing CBASP - along with compelling empirical evidence that supports its efficacy - the book is filled with illustrative case material that brings challenging clinical situations to life. Also covered are ways to measure treatment outcomes and recommended procedures for training and supervision.
