Abstract:
Objectives : The objective of this study is to develop a Japanese version of the Constitution in Chinese Medicine Questionnaire (CCMQ) in Chinese, which is comprised of 60 items with 9 sub-scales, and evaluate its reliability and validity. Methods : We conducted a survey of 130 participants in the Toyama area of Japan from Dec. 2005, to Feb. 2006. A test-retest method was used. Feasibility was evaluated by the response times to the questionnaire, and the response rates of the CCMQ items. Internal consistency within the sub-scales was assessed by Cronbach's α coefficient. Reproducibility was confirmed between the first and second occasions using weighted kappa and Spearman correlation. Lastly, criterion validity was evaluated by correlation between CCMQ and SF-36 sub-scales. Results : Response time was 8 minutes on average and its rate was nearly 100%. Internal consistency was achieved for each of the 9 sub-scales with a 0.65 to 0.79 α coefficient. Reproducibility ranged from 0.41 to 0.81 for the items, and from 0.79 to 0.88 for the sub-scales. Regarding the criterion validity, the “Gentleness type” sub-scale was positively correlated with SF-36 (0.46, P<0.001), while other 8 pathological constitutional types of the CCMQ were negatively correlated with SF-36 (-0.35 to -0.50, P<0.001) as expected. Conclusions : We developed a Japanese version of the CCMQ and found acceptable levels of reliability and validity using a survey of 130 subjects in Japan. This suggests that the CCMQ could be a useful tool in comparing the constitution profiles between Chinese and Japanese.
