The aim of this book is to illustrate a variant of the standard cognitive treatment for eating disorders. This therapy is based on the principle that assessing and treating the patient's process of worry and sense of control fosters greater understanding of the psychopathology of the eating disorder and increases the efficacy of cognitive treatment. The book is an edited collection of chapters that discuss the psychopathological roles played by control and worry in eating disorders, and provide a detailed description of the therapeutic protocol, which primarily focuses on the treatment of the cognitive factors of control and worry as core factor of a psychotherapy of eating disorders. In addition, the book shows contributions from other theorists in the field who have investigated the role of worry, preoccupation, and control, or who explore the connections between worry, control, and other emotional factors underlying eating disorders, such as perfectionism, self-esteem, and impulsivity.
