Abstract
Pediatric eating and feeding disorders, including anorexia nervosa, bulimia nervosa, binge eating disorder, and avoidant/restrictive food intake disorder, affect many children and teens throughout the United States. In the treatment of eating and feeding disorders, pediatric consultation-liaison psychologists are often involved in diagnostic evaluation, treatment planning, and coordination of care with the patient, family, and other multidisciplinary providers. This chapter summarizes evidence-based approaches to engaging patients with eating and feeding disorders and their families in evaluation, formulation, treatment, and disposition planning. The chapter providers review of levels of care and models for empirically supported treatment as well as considerations for adaptation based on factors commonly experienced in consultation-liaison practice. Case examples and other resources for the consultation-liaison psychologist are also provided.
