Social Competence and Eating Disorders: Development and Validation of the Anorexia and Bulimia Problem Inventory

Incompetence at solving interpersonal problems is a possible antecedent of anorexic and bulimic behaviors in college-age women. A role-play measure of interpersonal competence, the Anorexia and Bulimia Problem Inventory (ABPI), was developed empirically and then was tested in two validation studies. ABPI scores for two samples of college women were compared: a subclinical sample [extremely high scores on the Eating Attitudes Test (EAT)] and a control sample (extremely low EAT scores). Groups differed as predicted. The second study replicated and extended these findings. The ABPI scores of clinical, subclinical, and control samples of college women differed significantly. Bulimic bingers, purgers, and laxative users were least competent on the ABPI. A lack of group differences on the Helping Situations Inventory supported the ABPI's discriminant validity. A correlation between the ABPI and Beck Depression Inventory supported the ABPI's convergent validity. ABPI competence appears to be related to certain subtypes of eating disorders.
