The study was performed to determine the reliability and validity of the ‘Qi Blood Yin Yang Deficiency Questionnaire (Qi Blood Yin Yang DQ)’ for the 100 subjects with chronic fatigue. After 100 subjects respond to the ‘Qi Blood Yin Yang DQ’, Korean medical doctor classified the subjects into 4 groups such as Qi deficiency group, Blood deficiency group, Yin deficiency group and Yang deficiency group. 100 subjects were retested in the same way after 3 weeks. The reliability and the validity of the questionnaire were inspected. Internal consistency of the ‘Qi Blood Yin Yang DQ’ was excellent (Cronbach alpha 0.916). Test-retest reliability was good (intra-class correlation coefficient 0.699). Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The ‘Qi Blood Yin Yang DQ’ consisted of 4 factors. The factor 1, 2, 3 and 4 showed ‘Qi deficiency’, ‘Yin deficiency’, ‘Yang deficiency’ and ‘Blood deficiency’ respectively. The ‘Qi Blood Yin Yang DQ’ restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.
