Abstract

|
|
Objective : The aim of this study was to examine the psychometric features of the Korean version of the Eating Disorder Diagnostic Scale-the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (K-EDDS DSM-5).
Methods : A total of 72 patients diagnosed with eating disorders participated in the study. The diagnosis was based on the Korean version of the Eating Disorder Examination (KEDE) interview. All participants completed the K-EDDS and the Eating Disorder Examination Questionnaire version 6.0 (EDE-Q 6.0) for this study. The psychometric features of the K-EDDS were examined using exploratory factor analysis, convergent validity of agreement between the K-EDDS and the KEDE, and internal consistency.
Results : The exploratory factor analysis initially extracted 6-factor structures which were reconstructed into 4 factors of body dissatisfaction, binge behavior, binge frequency, and compensatory behavior based on appropriateness of the items. The internal consistency of the K-EDDS was fairly acceptable (Cronbach's alpha=0.72). The diagnostic agreement between the K-EDDS and the KEDE was high (98.61%). The 4 factors of the K-EDDS showed significant correlation with the 4 subscales of the EDE-Q 6.0.
Conclusion : Our data suggests that the K-EDDS is a reliable and valid tool for the diagnosis of eating disorders based on the DSM-5.
