Bulimia: an empirical analysis of psychodynamic theory.

This study examined two aspects of psychodynamic theory concerning bulimia nervosa, that bulimic patients ascribe to a traditionally feminine sex-role and that bulimic women have difficulty differentiating emotional from visceral sensations. 18 bulimic and 18 control women were administered the Bem Sex-role Inventory and the Eating Disorder Inventory. Contrary to dynamic theory, bulimic women were not more likely classified as traditionally feminine than control subjects; however, significantly more controls than bulimic women were classified as androgynous. Analysis of scores on the Eating Disorder Inventory's Interoceptive Awareness scale indicated a significant difference between bulimic persons and controls, providing strong support for the hypothesis that bulimic women have a difficult time differentiating emotional from visceral sensations.
