The cognitive model of Eating Disorders (ED) highlights dysfunctional cognitive patterns common to the different subtypes. Body dissatisfaction, which can be defined as the negative and subjective evaluation of one's body shape, i.e., negative thoughts and emotions concerning one's body image and the origin of pathological behaviours with the aim of modifying one's weight and body shape, thus appears to be a central transdiagnostic concept in the ED. It is, moreover, described as a major factor in the development, maintenance and relapse of the various types of ED.

It is suggested that Acceptance and Commitment Therapy (ACT) may be beneficial in treating body dissatisfaction insofar as body image inflexibility appears to influence the relationship between body image appraisal and coping strategies. ACT, which aims to develop psychological flexibility, appeared to us as a promising tool to manage body dissatisfaction in ED.

The investigators therefore aim to evaluate the feasibility and acceptability of a psychological management group for body dissatisfaction (9 or 10 weekly group session), based on ACT therapy, in patients suffering from an ED.
