Background Several attempts have been made to accurately diagnose the Sasnag Constitution. One of these attempts is to use a questionnaire. Questionnaire for the Sasang Constitution Classification(QSCC) has been revised several times and now used as QSCC II+. This study was designed to improve the accuracy of the revised Questionnaire for the Sasang Constitution Classification(QSCC II+). Method 1,054 people were gathered for this study and analyzed to check discrimination ability of current discriminant function of QSCC II+. They were outpatients who visited the hospital and the constitution was confirmed by the specialist of Sasang Constitutional Medicine. Results Accuracy of QSCC II+ at Soeumin was improved from 74.9% to 79.3%, and there were no significant difference at Soyangin and Taeumin. Conclusion New discriminant function was constructed through discriminant analysis. And the accuracy of QSCC II+ was generally improved, especially in Soeumin.

1. Objectives This is a statistical study on the Reliability and Validity of the Revised Questionnaire for the Sasang Constitution classification(QSCC II +). 2. Methods To analyze the reliability; we gathered the results of the QSCC II + 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 QSCC II + 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 QSCC II + to the diagnostic result of their Sasang constitutions, and analyzed by crosstabs to get the rate of accuracy of the QSCC II +, 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 $0.311{\sim}0.414$, which means the reliability of the QSCC II + is analytically significant. The accuracy of the results of QSCC II +, 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 QSCC II + isn't likely to agree to the diagnosis of the SCM specialists.

The purpose of this study is to examine validity to Soeum scales by QSCC II. For this study, the objects are 336 patients who were made a diagnosis of Soeumin and 422 patients of other constitutions in Oriental Medicine & Western Medicine Cooperative Health Examination Center KyungHee University Medical Center. A systematic analysis has been made and the results are as follows. 1. We made a frequency analysis in 758 examinees' questions and concluded that 35 questions, among which 30 questions were existing and 5 were new, had statistical significance in making a diagnosis of Soeumin by more than 10% in comparison with answer frequency of other constitutions. 2. Because confidence coefficient of 0.8011 revised Soeum scales(35) rises up as compared with that of 0.6319 existing Soeum scales(51), I think revised Soeum scales reflect trait of Soeumin well and it is liable to shorten question time by controling questions. 3. Soeumin's discrimination probability in Soeumin was 55.4% by QSCCII, but that rises up to 64.3% by discriminant function made by revised Soeum scales. So there is statistical significance in discriminant function. 4. When questions in QSCCII are divided into body-spirit(體形氣像), looks-attitude(容貌詞氣), temper- talent(性質才幹), continuous mind(恒心), avarice(心慾), physiological symptoms(生理的 證) and pathological symptoms(病理的 證), response frequency and constitution discrimination probability falls in questions about avarice and pathological symptoms.

Purpose : The purpose of this study is to get higher discriminability of the QSCCII on Taeumin. Methods : I analysed each item response rates on QSCCII of those who had been tested and diagnosed as Taeumin, Soeumin, Soyangin respectively by frequency analysis and reviewed Taeum scale of the current QSCCII by reliabiliry analysis and discriminant analysis. Results : 1. From the 758 results of QSCCII of those who were examined by professors, I made a revised Taeum scale which is consists of 17 items including 14 existing Taeum scale items and 3 new items from the other scales. 2. Reliability of revised Taeum scale is 0.5983, higher than that of existing Taeum scale, 0.5922. This means that revised Taeum scale reflects Taeumin's character more reliably than the existing one. 3. Hit-ratio of revised QSCCII on Taeumin is 60.3%, 2% lower than that of existing QSCCII.

By means of the statistical data which has been collected with newly revised QSCC made use of the outpatient group examined at Kyung-Hee Medical Center and an open ordinary person group, the author proceeded statistical analysis for the validation study of the revised questionnaire itself. First, check the accurate discrimination rate by performing discriminant analysis on the statistical data of the patient group. And next, sought T-score by applying the norms gained in process of standadization of the open ordinary person group to the Sasang scale score of the outpatient group and investigated the distinctive feature between the subpopulations which was devided in the process of multivarite cluster analysis. The result was summarized as follows ; 1. The validity of the questionnaire was established through the fact that the accurate discrimination rate the ratio between predicted group and actual group was figured out 70.08%. 2. At the profile analysis the response to the relevant scale showed notable upward tendency in each constitutional group and therefore it seems to be pertinent in the field of constitutional discrimination. 3. In the observation of the power of expression through the profile analysis of each constitutional group the Soyang group demonstrated the most remarkable outcome, the Soeum group was the most inferior and the Taieum group revealed a sort of dual property. 4. What is called the group of seceder out of three subpopulation of each constitutional group distinguished definitely from the contrasted groups at the point of the distinctive profile feature and the content is like following description. (1) The seceder group of Soyang-in showed considerably passive disposition differently from general character of ordinary Soyang group and an appearance attracting the attention is that they demonstrated comparatively higher response at Soeum scale (2) The seceder group of Taieum-in gained low scores in general that informed the passive disposition of the group and the other way of the general property of Taieum group which showed accompanied ascension in Taiyang-Taieum scales they demonstrated sharply declined score at Taiyang scale (3) The seceder group of Soeum-in demonstrated distinctive property similar to the profile feature of Soyang group and it notifies that the passive property of Soeum group was diluted for the most part. According to the above result, the validity of newly revised questionnaire has been proven successfully and the property of seceder groups could be noticed to some degree through the profile analysis on the course of this study. The result of this study is expected to use as a research materials to produce next edition of the questionnaire and it is regarded that further inquisition about the difference between the seceder group and the contrasted group is required for the promotion of the questionnaire as it refered several times in the contents of the main discourse.
