Validation of the Korean Version of Eating Disorder Examination

This study was attempted to investigate the validity and diagnostic efficiency of the Korean Version of Eating Disorder Examination(KEDE). The KEDE was administered to 106 female patients with eating disorders and 101 normal female college students by two raters who were proven to have a high inter-rater reliability. Discriminant validity was tested by ANOVA. Criterion related validity was tested by a regression analysis using the total score of the KEAT-26 as a criterion variable. Diagnostic efficiency was tested by ROC curve analysis. As the results, KEDE discriminated between eating disorders and normal females. That is, differences between total score of the KEDE and the subscale scores of ‘restraint’, ‘eating concern' and ‘weight concern' except ‘shape concern' of the KEDE were statistically significant. In criterion validation, subscales of the KEDE predicted 56% of variance in KEAT-26. ROC curve analysis showed 86.2% of diagnostic efficiency to discriminate the eating disorders group from the normal control group. These results indicate that the KEDE is a tool with high validity and diagnostic efficiency for the patients with eating disorders and related eating problems and also suggest that the KEDE may be an useful assessment tool to screen the patients with eating disorder and related eating problems on clinical and research purposes.
