TEMPERAMENT IN EATING DISORDERS

This study examined dimensional personality and temperamental characte ristics in women with eating disorders. Clinical symptoms, personality , and temperament were examined in 30 women with anorexia nervosa (AN) , 32 women with bulimia nervosa with no history of anorexia nervosa (B N), and 20 women with comorbid anorexia and bulimia nervosa (AB). Temp erament differed markedly across the groups on the Tridimensional Pers onality Questionnaire (TPQ) with AN women showing greater reward depen dence, BN women scoring higher on novelty seeking subscales, and AB wo men showing high harm avoidance. The TPQ subscales also displayed high er classification accuracy than other personality and symptom measures . Temperamental features are distinct across eating disorder subtypes. Temperament could reflect differential vulnerabilities for the develo pment of specific eating disorder symptom clusters. (C) 1995 by John W iley and Sons, Inc.
