Abstract

This study was attempted to investigate the reliability, factor analysis and norms of the Korean Version of Eating Disorder Examination Questionnaire(KEDE-Q). The KEDE-Q was administered to 306 female college students. Construct validity was tested by an exploratory factor analysis. Internal consistency was tested by Cronbach's α . The author also tried to make T score norms of the KEDE-Q using T score 70 as a cutoff point. By a factor analysis, 4 factors were extracted. Factor 1 was ‘weight and shape concern' which consisted of 11 items and explained 26.15% of variance, factor 2 was ‘restraint' which consisted of 5 items and explained 14.04% of variance,factor 3 was ‘eating concern’ which consisted of 5 items and explained 12.02% of variance and factor 4 was ‘shape and weight related body image’ which consisted of 2 items and explained 7.27% of variance. Cronbach's internal consistency was .92 for 'weight and shape concern’, .83 for ‘restraint’, .79 for ‘eating concern’, and .88 for ‘shape and weight related body image’. T score norms as a cutoff score were 53 for ‘weight and shape concern’, 16 for ‘restraint’, 10 for ‘eating concern’, and 9 for shape and weight related body image’. These results support that the KEDE-Q is a reliable and valid tool for evaluating the patients with eating disorder and related eating problems for the various purposes. The author also demonstrates T score norms of the KEDE-Q as a cutoff score of each subscale.
