EQUIVALENCE OF BODY-IMAGE DISTURBANCES IN ANOREXIA AND BULIMIA-NERVOSA

A silhouette method, the Body Image Assessment, was used to measure self-evaluation of current and ideal body size in three groups: Ss with with anorexia nervosa (n = 37), Ss with bulimia nervosa (n = 59), and normal control Ss (n = 95). Current and ideal body size measures were contrasted across the three groups using body mass index as a covariate to control for the Ss actual body size. Both eating disorder groups judged current body size to be larger and ideal body size to be thinner relative to control Ss. When actual body size was not statistically controlled, Ss with anorexia nervosa judged current body size to be thinner than did control Ss and Ss with bulimia nervosa. These data illustrate the importance of controlling For actual body size when investigating the self-evaluation of body size.
