In the 1950s, Albert Ellis pioneered a form of psychotherapy that combined ways of detecting and changing irrational thoughts with techniques for replacing negative behaviours with positive ones. This type of cognitive behavioural therapy, called rational emotive behaviour therapy (REBT) by Ellis, proved especially effective at relieving problems like anger, anxiety and depression. In this book, author William Knaus, a close associate of Ellis, develops the best REBT techniques into a powerful and comprehensive self-help workbook for the treatment of depression. Following in New Harbinger's tradition, this workbook is written in an easy-to-use, step-by-step format. It offers readers powerful strategies for overcoming depression in simple, direct language, amply illustrated with stories and reinforced by techniques they can practice right away. Along with other "New Harbinger" titles like "The Anxiety and Phobia Workbook" and "The Anger Control Workbook", this major CBT/REBT workbook for depression is destined to become a trusted resource for people with depression, recommended by therapists and sought out by people inspired to change their own lives for the better.
