Bulimia nervosa: sex role attitude, sex role behavior, and sex role related locus of control in bulimarexic women.

Thirty-four women with bulimia nervosa and 34 women without bulimarexic symptoms (but matched for age, weight, deviance from ideal weight, and educational status) were compared as to how liberated their attitude towards the woman's role in society (= their sex role attitude, SRA) and their actual own behavior as females (= their sex role behavior, SRB) were. The degree to which their general attitude towards sex role and their own sex role behavior differed from each other was also investigated. Experimental and control group were also compared concerning their sex role related locus of control (SRLC). SRA and SRB were significantly less liberated in the bulimarexic group than in the control group. In addition, the bulimarexic group showed a wide gap between their general attitude (SRA) and actual behavior (SRB) as to the degree of liberation. No such discrepancy was found in the control subjects. The sex related locus of control data showed that bulimarexic women had significantly higher external and fatalistic control, and lower internal control than the comparison subjects.
