The authors compared 55 bulimic subjects and 55 normal control subjects
using the Beck Depression Inventory, a new scale designed to detect
cognitive distortions (the Bulimia Cognitive Distortion Scale), and several
perceptual and attitudinal measures of body image. There were significant
differences between the bulimic and control groups on all measures except
estimates of face width. These findings are discussed in terms of a
multifactorial theory of the psychopathogenesis of bulimia.
