Abstract
OBJECTIVES
The Eating Disorder Examination Questionnaire, version 6.0 (EDE-Q version 6.0) and the Clinical Impairment Assessment Questionnaire (CIA) measure attitudes and behavioral features of eating disorders and impairments secondary to eating disorders, respectively. The aims of this study were to examine the reliability and the validity of the Korean versions of the EDE-Q version 6.0 and the CIA.
METHODS
Four hundred nineteen participants (370 female university students and 49 women with eating disorders) completed the EDE-Q version 6.0, the CIA, the Body Shape Questionnaire (BSQ) and the Weight Concern Scale (WCS).
RESULTS
Excellent internal consistencies were obtained for the EDE-Q version 6.0 (Cronbach's α=0.92) and the CIA (Cronbach's α=0.91). Exploratory factor analysis of CIA extracted the 3 factors of personal, social, and cognitive impairments, as the original CIA had. The EDE-Q version 6.0 and the CIA were well correlated with the BSQ and the WCS, in respect to their contextually concordant variables. Patients with eating disorders had higher scores both in the EDE-Q 6.0 and the CIA than university women had, supporting good discriminant validity.
CONCLUSIONS
The EDE-Q version 6.0 and the Korean versions of the CIA had adequate reliability and validity. These data will help clinicians and researchers to use the EDE-Q and the CIA in diagnosis, prevention and intervention of eating disorders in Korea.
