title: Diabetes-related distress and physical and psychological health in chinese type 2 diabetic patients.
abstract: OBJECTIVE
  To validate a Chinese version of the Diabetes Distress Scale (CDDS).
  
  
  METHODS
  The CDDS was derived using forward-backward translation and administered in 189 Chinese type 2 diabetic patients with evaluation of its psychometric properties.
  
  
  RESULTS
  On the basis of principal-component analysis, three factors of the 15-item version of the CDDS (CDDS-15) accounted for 63% of the variance. The correlation coefficient between the original 17-item and 15-item scales was 0.99. The Cronbach α for internal consistency was 0.90, and the test-retest reliability coefficient was 0.74. The CDDS-15 score was significantly associated with glycemic control, obesity, depressive symptoms, and quality of life.
  
  
  CONCLUSIONS
  The CDDS-15 is a valid and reliable instrument to assess diabetes-related distress.
