We verified the reproducibility of constitution by IGM and the agreement rate between sasang constitution by QSCCII and constitution by IGM. We analyzed the results of 64 subject who were judged as identical sasang constitution by repeated QSCC II. First, we compared the two results of constitutions by IGM hat peformed by one O.M.D(Oriental Medicine Doctor) at an interval of one year. Second, we examined hypothesis established by one O.M.D, that is about relation of constitutions by IGM and QSCCII, such as I type-Taeeumin, II type-Soyangin and III type-Soeumin in constitutions. There were no statistical significances in reproducibility of constitution by IGM. Although there was a tendency of relevance of sasang constitution by QSCC II with constitution by IGM, there was no statistical significance. Hypothesis that is established by clinical experiences must be verified by an effective statistical method. And there is a necessity to complement the method including mechanical measurements about constitution classification which are performed by a diagnosis relying on individual intuition.
