Transdiagnostic models of eating disorders and therapeutic methods: The example of Fairburn’s cognitive behavior therapy and acceptance and commitment therapy

The present article aims to present a transdiagnostic approach to eating disorders (anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified) using the example of two relatively new types of therapy: Cognitive Behavior Therapy (CBT), based on Fairburn’s model, and Acceptance and Commitment Therapy (ACT). Theoretical frameworks, psychopathology, proposed change mechanisms, as well as objectives and selected therapeutic techniques are discussed for both approaches. Directions for further research comparing the efficacy of the two approaches, the factors that moderate their outcomes, and the possibilities of integrating the two models are also suggested.
