Validity and reliability of the Chinese version of the Diabetes Distress Scale in type 2 diabetes patients in community settings / 中国实用护理杂志

ABSTRACT

Objective@#To verify the validity and reliability of the Chinese version of the Diabetes Distress Scale(CDDS) in community type 2 diabetes patients.@*Methods@#The reliability and validity of the CDDS was tested among 250 patients with type 2 diabetes.@*Results@#The CDDS included four subscales emotional burden subscale, physician-related distress subscale, regimen-related distress subscale, and diabetes-related interpersonal distress. Four factors were extracted by exploratory factor analysis and could explain 78.89% of the total variance. The Cronbach α coefficient of the CDDS was 0.94, the Cronbach α coefficient of four factors was 0.90-0.93; the test-retest reliability was 0.74, the test-retest reliability was 0.54-0.79. The scores of CDDS correlated with the scores of DSAS-2 and HbA1c (r value was 0.42, 0.20, P<0.01).@*Conclusions@#The CDDS has acceptable reliability and validity, which can be used to evaluate distress among patients with type 2 diabetes in community settings.
