This state-of-the-art guide provides a powerful transdiagnostic approach for treating adolescent eating disorders (anorexia nervosa, bulimia nervosa, binge-eating disorder, and others) in either outpatient or inpatient settings. It describes how enhanced cognitive behavior therapy (CBT-E)—the gold-standard treatment for adult eating disorders—has been systematically adapted and tested with younger patients. With a strong motivational focus, CBT-E gives the adolescent a key role in decision making. The book presents session-by-session guidelines for assessing patients, determining whether CBT-E is appropriate, developing case conceptualizations, conducting individualized interventions, addressing medical issues, and involving parents.
