Body image assessment in anorexia nervosa patients and university students by means of video distortion: a reliability study.
It is well known that anorexia nervosa is characterized by a disturbed body image. The video distortion method is one of the many methods to systematically study the perceptual aspect of this body image. Using a distorted image of her own appearance, the subject is asked to reconstruct the 'exact' measures of her body and to indicate her ideal image. The reliability of this method has been assessed in a study involving 67 anorexic patients and 105 female university students. Test--retest results within the same session and over a one-week interval were sufficiently constant. Nonetheless, for both anorexics and controls, significant differences were found between estimates with a narrowed (thin) image initially and those with a widened (fat) image initially. Both groups underestimate their body measures and only significantly differ on estimates of their ideal image, with anorexics clearly less underestimating their ideal image than students.
