Abstract
The purpose of this research was to clarify the invariability of factor structure of QOL index. We examined gender and age differences in the factorial structure of QOL index using simultaneous factor analysis, constrained all parameters equally, with two representative samples of elderly community residents. The subjects were the elderly above 65 years old living at A town (1,152) and K village (942) in Okayama prefecture. The result showed that the model containing 9 items loading on three first - order factor and one second-order factor was found to fit gender and age datas adequately, GF1 being above 0.9 and RMSEA below 0.05. Given these results, QOL index is multidementional on the Level of first-order factor and on the second-order, a unidementional interpretation is more appropriate
