Abstract

Objective: The goals of this study were to evaluate how well the Eating Disorder Inventory (EDI) predicted specific eating disorders as identified by the Survey of Eating Disorders (SED), and to identify the most predictive EDI scales. An additional goal was to evaluate the EDI as a screening instrument for eating disorders among a large nonclinical group of women. Method: The community-based study sample consisted of 1245 Norwegian women between age 18 and 50 years (mean 23). Subjects filled out the EDI and the SED. Results: The strongest predictors of SED-defined eating disorders were the EDI scales bulimia (BN) and drive of thinness (DT) and body mass index (BMI). When we classified women with an EDI sum score of 40 or higher as having an eating disorder (ED), the sensitivity was 38% and the specificity was 90%, compared to the SED diagnosis of ED. Discussion: Our findings suggest modest agreement between the EDI and the SED, and modest sensitivity and specificity of the EDI. While these instruments, perhaps with some modification, may be adequate for use in selected research applications, they should probably be supplemented with additional information in a clinical or treatment setting.
