This is a statistical study on the Reliability and Validity of the Revised Questionnaire for the Sasang Constitution Classification(QSCCⅡ+).
To analyze the reliability, we gathered the results of the QSCCⅡ+ of 266 people. Each person took the questionnaire three times, and the interval of the examinations were about one year. With the results, we used stratified analysis to check up the consistency rate of three examinations, and analyzed the tendency of agreement by crosstabs to get the kappa value. For the validity, we gathered the results of the QSCCⅡ+ of 587 people who were Taeumin, Soyangin, Soeumin. They took the questionnaire once, and SCM specialists strictly examined to diagnose their Sasang constitutions. We compare their results of the QSCCⅡ+ to the diagnostic result of their Sasang constitutions, and analyzed by crosstabs to get the rate of accuracy of the the QSCCⅡ+, and the kappa value for the measure of agreements.
3. Results and Conclusions
The expected rate to get the same results was 54.5% in Soyangin, 68.1% in Taeumin, 65.7% in Soeumin, and kappa value was 0.311~0.414, which means the reliability of the QSCCⅡ+ is analytically significant. The accuracy of the results of QSCCⅡ+, compared to the diagnosis of the SCM specialists, was 58.4%, but increased up to 60.8%, and validity also became moderately good(K=0.412) by age limitation. Because in the 70's results of the QSCCⅡ+ isn't likely to agree to the diagnosis of the SCM specialists.
