The purpose of the present study was to assess body perception in eating di
sorders and its meaning in therapy. A total of 44 patients, 25 bulimia nerv
osa and 19 anorexia nervosa, admitted at a specialized in-patient treatment
center participated in the present study. Body size estimation procedures
(video-distortion and image-marking techniques) and self-report questionnai
res were used for the assessment. No significant differences were found in
actual body size estimation between the two eating disorder groups. either
before or after therapy. It emerged after therapy that the outcome was not
related to body size estimation. These findings suggest that there is no ev
idence for a serious impairment of body perception (size estimation) in eat
ing-disordered patients, but rather for a disturbance in the emotional aspe
ct of body image, as expressed in negative body attitudes, Body size percep
tion does not appear to be a predictor of treatment outcome in eating disor
