A method for the assessment of body image disturbance in patients with eating disorders.

This paper describes a new method for assessing body image disturbances in eating disordered patients. Fifteen bulimic, 25 anorexic, and 24 normal controls served as subjects. All subjects were matched for age and height, and bulimics and controls were matched for weight as well. All subjects completed the Perceived Body Image Scale (PBIS), which required subjects to report on how they see themselves when they look in the mirror, how they think they look, and how they feel themselves to be, reflecting the perceptual, cognitive, and affective aspects of body image, respectively. Subjects also selected their ideal. An objective rating was made. Objective ratings had a high correlation with the subject's weight. Results showed that both eating disorder groups demonstrated more apparent body image disturbance than controls, and that the bulimics showed significantly greater body image dissatisfaction than anorexics or controls. The potential use of the PBIS as a research and clinical instrument is discussed.

Adolescents with bulimic and nonbulimic eating disorders.

Twenty-eight adolescents with eating disorders were analyzed in a study that included a retrospective examination of their hospital records and a letter to their family doctor and the patient. These 28 patients were dieting to lose weight, with nine reporting episodes of overeating and vomiting. The clinical characteristics of the bulimic patients versus the nonbulimic are contrasted. Bulimic patients tended to be older and ill for longer. They had a higher weight score, vomited more, and used laxatives and diet medications more frequently. They threatened suicide more often than nonbulimics and many had been overweight previously. Poor outcome was positively associated with bulimia, longer duration of illness, and older age of presentation, but not with a lower weight during the illness. However, with the exception of the presence of vomiting and being less likely to feel fat, these differences in clinical characteristics between bulimic and nonbulimic groups did not approach the level of statistical significance.
