This online version of the Mastery of Your Anxiety and Panic, Client Workbook has been updated to include strategies and techniques for dealing with both panic disorder and agoraphobia. The program outlined is based on the principles of cognitive-behavioural therapy (CBT) and is organised by skill, with each chapter building on the one before it. It covers the importance of record-keeping and monitoring progress, as well as breathing techniques and thinking skills. The main focus of the treatment involves learning how to face agoraphobic situations and the often frightening physical symptoms of panic from an entirely new perspective. Self-assessment quizzes, homework exercises, and interactive forms allow patients to become active participants in treatment and to learn to manage panic attacks, anxiety about panic, and avoidance of panic and agoraphobic situations.
