Results Psychometric analysis supported the reliability and validity of the C-ADS and three subscales：sense of self-control, psychological impact of diabetes,belief and attitude toward personal effort. These three factors explained 76.44% of the variance. The findings also demonstrated a high factor loading indicating good construct validity of the ADS. The criterion validity was acceptable. The Cronbach＇s c~ coefficient was 0.731 and the test-retest reliability was 0.926. Conclusion The C- ADS is a reliable and valid measure for patients＇ stress and psychosocial burden among Chinese people with type 2 diabetes.
