Validity and Reliability of the Korean Version of the Diabetes Acceptance and Action Scale (DAAS-K)

Abstract

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of the Diabetes Acceptance and Action Scale-Revised (DAAS-R) for Korean patients with type 2 diabetes. Methods: The survey was conducted from September 1, 2021, to September 30, 2021, through a survey institution for patients diagnosed with diabetes who understood the purpose of the study and voluntarily agreed to participate. A total of 231 individuals with type 2 diabetes participated in this study. After performing forward and backward translations of the original version of the Diabetes Acceptance and Action Scale-Revised (DAAS-R) into Korean, its constructive validity (confirmatory factor analysis), concurrent validity and reliability were assessed. Concurrent validity was confirmed through the correlation between acceptance and action, quality of life, diabetes self-stigma, and experiential avoidance. Results: Construct validity, measured using confirmatory factor analysis, showed a good fit. The DAAS-K was positively correlated with acceptance and action, quality of life, and negatively correlated with diabetes self-stigma and experiential avoidance. As for internal reliability, the Cronbach’s α of the DAAS-K was .95. Conclusion: The DAAS-K can be applied to assess diabetes acceptance and action in Korean patients with type 2 diabetes and to compare the levels of psychological flexibility of patients with diabetes internationally.
