The purpose of this study is to analyze of the practice of health promotion on adult through Trantheoretical Model. The Transthoretical Model is an integrative model, that key constructs form other theories are integrated. The model also includes a series of independent variables, the Self Efficacy and the Decisional Balance. The variables of the Self Efficacy are 5 items, and the Decisional Balance are 10 items. To assess of the validity, the Rating Scale of IRT(Item Response Theory) were used. This study was analyzed in 6 facets(gender, age, scholastic ability, offspring, income and items) by using Facets program(Linacre. 2000) for the goodness-of-fit. As a result of IRT, the Self Efficacy and the Decisional Balance in Trantheoretical Model cannot be used the sum of items. In the Self Efficacy, all facets are significant difference except the gender, and all the facets groups don't have significant goodness-of fit index. In Decisional Balance, all facets are significant difference except the gender and the income. The elementary school ability and the more 4 offsprings have significant goodness-of fit index. This IRT study showed the more detail conclusion for Transthoretical Model.
