OBJECTIVE To compare the Eating Disorder Examination (EDE) with the self-report version (EDE-Q) in a population of adolescents with anorexia nervosa. METHOD Twenty-eight adolescent women meeting criteria for anorexia nervosa were assessed using both measures. The self-report version (EDE-Q) was given both before and (Time 1) after (Time 2) administration of the interview-based version (EDE). RESULTS The results comparing the EDE with the EDE-Q at Time 1 were consistent with previous studies. Specifically, high correlations were generated on each of the four subscales (Dietary Restraint, Eating Concern, Shape Concern, Weight Concern) where the EDE-Q consistently overestimated the EDE. However, significant differences between the two measures were found on all subscales except Dietary Restraint. Agreement was best for the Weight Concern subscale and worst for the Eating Concern subscales. Comparing the EDE with the EDE-Q at Time 2, agreement improved for all subscales whereas significant differences were found on only two of the four subscales (Eating Concern and Shape Concern). DISCUSSION Adolescents with anorexia nervosa report information on the EDE-Q as well as any of the other populations that have been studied. The results suggest that providing information to participants before they complete the self-report measure could improve scores on the EDE-Q.
