Body-weight self-schema: Determinant of mood and behavior in women with an eating disorder

The schema approach to self-concept was used to investigate the association between body-weight self-conception and self-esteem, negative affect states, and disordered eating behavior in women with anorexia nervosa (n = 26) or bulimia nervosa (n = 53) using experience sampling methodology. We predicted that self-esteem would be lower and unpleasant affect and disordered eating behaviors would be higher when the body-weight self-schema was activated in working memory compared to when non-weight-related self-schemas were activated. Participants recorded the currently activated self-schema, self-esteem, affect, and behavior in response to an alarm-watch signal 5 times daily for 5 days. Activation of the body-weight self-schema was associated with lower self-esteem and higher negative affect, but not higher levels of disordered eating behavior. Low self-esteem and negative affect, however, were associated with disordered eating behavior. Findings have important implications for treatment of eating disorders.
