This new fourth edition of Treatments of Psychiatric Disorders has been streamlined, and this section on eating disorders appropriately reflects this process. The previous edition had eight chapters in this section; in this current edition, the section has been pared down to four chapters. Despite the shortening of the content component, these chapters provide comprehensive, concise, up-to-date summaries of the current state of the art of the interventions reviewed for the treatment of anorexia nervosa, bulimia nervosa, and binge-eating disorder. These chapters provide research-based as well as clinical evidence for the efficacy of psychological and pharmacological treatments, as well as family and intensive therapies. However, recommendations for the treatment of eating disorders, especially for anorexia nervosa, suffer from a paucity of evidence-based studies. Even when such evidence exists, such as for the efficacy of cognitive-behavioral therapy for bulimia nervosa, such interventions are not widely practiced in the community because of a lack of adequate dissemination and training. Choosing the most effective treatment approach for someone with an eating disorder should take into account a number of variables, including physical and psychological risk, motivation, social support, comorbidity, and age.
