1. The purpose of study The problem lies in the Sasang-constitutional-medicine is a subjectiveness of diagnosis that can be varied by every donor. Questionnare for the Sasang Constitution Classification II(QSCCII) was invented to solve this problem. This study was conducted for two purpose. The one is re-value the QSCCII. The other is to make a basis to upgrade QSCCII. 2. The method of study QSCCII was administered to 537 patients at Kyung Hee Oriental Medicine Hospital. Data was collected during 19 months from september 2000 to march 2002. For the purpose of this study, the collected data was analyzed by crosstabs, variation analysis and discrimination analysis. The analyzing program was SPSS 8.0 for Windows. And using this program I made the judgmental equation to re-value the QSCCII. 3. The result of study 1) not applied intensifying value The diagnostic discrimination abilities of the QSCCII is 61.5% about Taeyangin, 57.7% about Soyangin, 67.2% about Taeumin, 68.8% about Soemin. And its average is 65.0%. 2) applied intensifying value The diagnostic discrimination abilities of the QSCCII is 76.9% about Taeyangin, 59.9% about Soyangin, 68.9% about Taeumin, 71.2% about Soemin. And its average is 67.3%. 3) I propose a new diagnostic possibility with a different discriminant analysis and increase 42.3% of diagnostic discrimination ability considering 25% of accident diagnostic discrimination ability. 4) Development and complement of Taeyangin and Soyangin questions is needed to increase the accuracy of diagnosis.
