This psychotherapist's guide is based on the treatment of bulimia nervosa and psychogenic overeating by cognitive behavioral therapy (CBT). CBT has proven to be the most effective treatment to help clients improve eating habits and overcome an eating disorder. The main phases of the treatment program are: changing behavior patterns, identifying triggers for overeating or cleansing, as well as preventing relapse. The treatment program pays special attention to normalizing the eating pattern, eliminating the triggers of overeating and cleansing, regulating emotions and teaching how to solve problems. The manual is recommended to be used in conjunction with a self-help manual or a client's practice manual.
