Validity and Reliability of a Korean Diabetes Eating Problem Survey-Revised.

PURPOSE: This study was to translate the Diabetes Eating Problem Survey-Revised (DEPS-R), originally developed for adolescents with type 1 diabetes mellitus, into Korean, and to determine its factor structure while testing its validity and reliability among Korean adolescents with type 1 diabetes.

METHODS

The participants were recruited from the Diabetes Center of a university hospital or type 1 diabetes camp. A total of 205 Korean adolescents aged 13-18 years diagnosed with type 1 diabetes completed a self-reported questionnaire. After the DEPS-R was translated into Korean (KDEPS-R), confirmatory factor analyses were performed and the criterion and convergent validity were tested.

RESULTS

This four-factor model was validated using a confirmatory factor analysis. The sensitivity and specificity of the KDEPS-R based on the Korean version of the Eating Attitudes Test-26 (KEAT-26) as the criterion for eating disorders were .52 and .81, respectively. The KDEPS-R scores significantly correlated with the glycated hemoglobin levels and the Korean versions of the Beck Depression Inventory-II and KEAT-26 scores, indicating convergent validity. The Cronbach α for the total score was .85.

CONCLUSION

The KDEPS-R is a reliable and culturally validated tool for evaluating diabetic eating disorders in Korean adolescents with type 1 diabetes. The KDEPS-R can help investigate related prevalence rates and test the effectiveness of intervention programs for Korean adolescents with type 1 diabetes.
