Psychotherapy is essential for recovery from an eating disorder, yet it is complex and prolonged and often yields only marginal therapeutic gains.1 Various approaches exist, but few have shown efficacy in controlled clinical trials. The Research Triangle Institute (RTI) International–University of North Carolina at Chapel Hill Evidence-based Practice Center (RTI-UNC EPC) reviewed the treatment efficacy literature for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) in studies published between 1980 and September 2005. The systematic review identified 30 treatment studies for AN, 47 for BN, and 25 for BED.2

This article presents information from that review regarding the psychotherapeutic interventions that were shown to be efficacious for AN, BN, and BED. Medication trials without psychotherapy components are not reviewed. The paper is divided by therapeutic approach; within each approach, the variations on the presentation necessary to address the specific therapeutic needs of each eating disorder type are discussed.

Cognitive Behavioral Therapy
Cognitive behavioral therapy (CBT) for eating disorders focuses on how thoughts, feelings, and behaviors develop into patterns that maintain disordered eating. The intention of CBT is to use cognitive techniques to challenge unhelpful or distorted thoughts while using behavioral techniques to reduce eating disorder behaviors. The patient is asked to maintain daily monitoring logs of foods eaten, disordered eating behaviors, thoughts, feelings, and details of when, where, and with whom those behaviors occurred. Self-monitoring yields objective information for use with behavioral interventions such as cue recognition, desensitization, or reinforcement. It also reveals patterns of automatic thoughts (e.g. ‘I am fat,’ ‘I can’t eat this,‘ or ’I am weak’) that reflect broader core beliefs. Cognitive restructuring challenges these thoughts with rational alternatives. CBT is effective when beliefs change, automatic thoughts decrease, and problem behaviors are reduced. CBT is often compared with interpersonal psychotherapy (IPT) in treatment studies. IPT focuses on the patient’s relationships with peers and family with the intention of reducing presenting symptoms by modifying personal problems in those relationships. IPT examines how disputes, role transitions, grief, and skill deficits are managed and influence functioning.

Anorexia Nervosa
CBT applied to AN typically focuses on cognitions relating to fear, control, low self-esteem, body-image distortion, and perfectionism, with behavioral targets including decreasing caloric restriction, decreasing physical activity, and reducing avoidance. Two studies of patients receiving CBT while underweight failed to show evidence that CBT improved body mass index (BMI) or weight or was superior to other treatment strategies at the end of treatment or at follow-up.3,4
