Abstract:
Objective:To investigate the reliability and validity of the Chinese Version of Dimensional Anhedonia Rating Scale (DARS).Methods:136 subjects who were diagnosed with depressive disorder and 30 healthy controls were selected to complete the Chinese version of DARS, Hamilton Depression Scale (HAMD 17), and Hospital Anxiety and Depression Scale (HADS). Cronbach’s alpha coefficient, test-retest reliability and confirmatory factor analysis were conducted. HADS and HAMD 17 were considered as the gold standard to investigate the criterion validity of the Chinese version of DARS. Results:The Cronbach’s α of the Chinese version of DARS was 0.97, the coefficient of the four domains ranged from 0.89 to 0.96. The intraclass correlation coefficient ( ICC) of test-retest reliability was 0.97， ICC of four domains ranged from 0.89 to 0.95 ( P<0.01)．The results of confirmation factor analysis of the Chinese version of DARS were as followed: χ 2/ df=2.02, GFI=0.88, RMSEA=0.08, CFI=0.96, and TLI=0.96. Validity: The total score and four domains of the Chinese version of DARS were significantly correlated with the seventh item of HAMD ( r=-0.38- -0.52, P<0.01) and all five items of HADS score ( r=-0.57- -0.75, P<0.01). There was significant difference between depression group and health control group. Conclusion:The Chinese version of DARS has good psychometric properties with adequate reliability and validity, and could be applied to assess the anhedonia of depression in China.
