Clinical and personality correlates of body size overestimation in anorexia nervosa and bulimia nervosa

Abstract

A video camera technique was used to assess perceived actual and ideal size in patients with a restricting type of anorexia nervosa (n = 17), bulimia nervosa patients with previous anorexia (n = 23), bulimia nervosa patients with no previous anorexia (n = 24), phobic controls (n = 18), and normals (n = 33). Bulimic patients with previous anorexia demonstrated a significantly greater tendency to overestimate their actual body size (p <.05) than subjects in the restricting anorexic or control groups. Previously anorexic bulimics also demonstrated more overall clinical and personality disturbance than any of the other groups (p <.01). Body size overestimation and dissatisfaction were strongly associated with the duration and severity of the eating disturbance in previously anorexic bulimics but there were no clear relationships between clinical or personality disturbances and body size distortions in the restricting anorexic or never-anorexic bulimic groups. Results are discussed with respect to the importance of refining diagnostic criteria for subtypes of anorexia and bulimia nervosa. Multitrait-multimethod methodologies are recommended for purposes of elucidating “body image disturbance” and its importance in the etiology and maintenance of eating disorders.
