Clinical features of eating disorders and individual psychological functioning.

Relationships between the clinical features of eating disorders and individual psychological functioning were investigated in a population of 114 eating-disordered females, which consisted of 63 bulimics, 9 anorexics, 7 bulimic anorexics, 23 with eating disorders not otherwise specified, and 12 with indications of an eating disorder, but without sufficient data for further differential diagnosis. No significant differences in psychological functioning were found when diagnosis was used to classify the subjects into groups, but significant differences did emerge when subjects were classified by specific clinical features. Among the clinical features associated with greater psychopathology were: low body weight, frequent weight fluctuations, amenorrhea of longer duration, purging via laxatives, frequent exercising, and more frequent binges of longer duration.
