Assessment of validity and reliability of Chinese version of tools in measuring yangsheng

Objective To assess the reliability and validity of Chinese version of tools in measuring yangsheng. Methods Chinese version of tools in measuring yangsheng was administered to 706 elderly citizens and evaluated for the reliability and validity. Results The fittingness of the both exiting model were unidentified. A model of six factors and twenty-six items was determined using exploratory factor analysis. The fitness of such model was perfect (RMSEA=0.050, AGFI=0.871, GFI=0.902, NFI=0.903, CFI=0.953) and all the construct reliability were more than 0.6 while the average variance extracted were higher than 0.5 except the diet yangsheng factor. The Cronbach's α of Chinese version of tools in measuring yangsheng was 0.918 and Cronbach's α of factors were all above 0.7. Conclusion The Chinese version of tools in measuring yangsheng appears to have good validity and reliability to estimate the Yangsheng of elderly citizens in China.
