Objectives: The study aimed to examine whether dissociation and attitudes towards change were associated with the psychopathology in patients with eating disorders (EDs) at 1-year follow-up.
Method: The study included 110 females with anorexia nervosa and bulimia nervosa (48 and 62 respectively). At the beginning of the study and 1 year later, they were assessed by means of the following questionnaires: Dissociative Experiences Scale, Attitudes Towards Change (ACTA), State-Trait Anxiety Inventory, Rosenberg Self-Esteem Scale, Beck Depression Inventory, Eating Attitude Test, Bulimic Investigatory Test Edinburgh and Body Shape Questionnaire (BSQ).
Results: No statistically significant differences were found between both diagnostic groups regarding dissociation scores. The ACTA at baseline, specifically for patients in the contemplation stage, mediate the effect of dissociation on the psychopathological outcome.
Discussion: These findings suggest that dissociation might be a transdiagnostic feature related to the EDs outcome. The psychotherapeutic framework must take it into account, particularly in patients in the contemplation stage.
