Identity Impairment and the Eating Disorders: Content and Organization of the Self-Concept in Women with Anorexia Nervosa and Bulimia Nervosa

Objective: The cognitive model of the self-concept was used to test the theoretical proposition that disturbances in overall identity development are a core vulnerability that lead to formation of a fat body weight self-definition and eating disorder symptomatology. Method: Structural properties of the self-concept, availability in memory of a fat body weight self-schema, and eating disordered attitudes and behaviours were measured in women with anorexia nervosa (AN) (n¼26), bulimia nervosa (BN) (n¼53) and controls (n¼32). Results: Women with (AN) and (BN) had fewer positive andmore negative and highly interrelated self-schemas compared to controls, and women with BN showed information processing evidence of a fat self-schema available in memory. These self-concept properties predicted eating disordered attitudes and behaviour. Discussion: Disturbances in the overall collection of identities— an impoverished self—is an important contributor to eating disorder symptomatology. The development of new positive selves may be an important factor in recovery.
