Reliability and validity of the Chinese version of rumination response scale in depressed patients
Objective To examine the reliability and validity of the Chinese version of the Rumina- tion Response Scale（RRS--C） in Depressed patients. Methods A sample of 212 depressed patients was tested. The RRS--C＇s coefficient of Cronbaeh＇s a, mean inter--item correlation coefficient and score-- factor correlation coefficient were examined. Using confirmatory factor analysis,the three--factor Model was tested. Results The Cronbaeh＇s a coefficient of the RRS--C was 0.88. The Cronbaeh＇s a coefficients of 3 factors were among 0.67~0.84. The mean inter--item correlation coefficient of the RRS--C was 0.26. The intra--class correlation coefficients of RRS--C＇s three factors ranged from 0.71~0.94. The intra--class correlation coefficients of the 3 factors ranged from 0.29~0.32. The CFI= 0. 913, GFI= 0. 905, X2 /v~2, RSMEA= 0. 072, and all of them met the criteria standards for adequacy of fit. Conclusions The Chinese Version of Rumination Response Scale was of good reliability and validity in depression patients, which serves as an excellent measuring tool for assessing rumination in Chinese depression patients.
