ABSTRACT
The current medical classification suggests that there are several distinct eating disorders (i.e., anorexia nervosa, bulimia nervosa, binge-eating disorder, and other eating disorders), each requiring a specific treatment. However, numerous studies and clinical observations have shown that eating disorders in fact share most of their clinical features and often migrate from one diagnosis to another. This chapter begins by discussing how eating disorders are currently classified; it describes their main features and ends by bringing these features together to illustrate an alternative way of thinking about eating disorders—the transdiagnostic perspective, upon which the “enhanced” cognitive behaviour therapy (CBT-E) described in this book is based.
