Abstract

Objective: To develop a screening tool for the identification of bulimia in ambulatory practice.

Design: Administration of a 112-item questionnaire about eating and weight-control practices to women with known bulimia and to healthy control patients. Questions were compared with DSM-III-R criteria of bulimia as a “gold standard.”

Setting: Self-help group for eating disorders and hospital-based primary care practice.

Subjects: Thirty of 42 women with known bulimia met DSM-III-R criteria for current bulimia, and 124 of 130 control patients met the criterion of no history of an eating disorder.

Main results: Thirteen individual questions discriminated between bulimic subjects and control subjects with a sensitivity and specificity of >75%. When these questions were entered into a stepwise logistic model, two questions were independently significant. A “no” response to the question “Are you satisfied with your eating patterns?” or a “yes” response to “Do you ever eat in secret?” had a sensitivity of 1.00 and a specificity of 0.90 for bulimia. The positive predictive value, based on a 5% prevalence, was 0.36.

Conclusions: A set of two questions may be as effective as a more extensive questionnaire in identifying women with eating disorders, and could be easily incorporated into the routine medical history obtained from all women.
