The health-related QOL (HRQOL) has been used extensively in clinical and epidemiological research and health service studies. Especially, the Medical Outcome Study Short-form 36-Item Health Survey (SF-36) is a widely used health status measure. However, a Korean version has not been developed and tested yet. The purpose of this study was to develop a Korean version of the Short-form Health Survey (SF-36) for use in health related quality of life measurements for Korean elderly people. SF-36 data from 90 healthy elderly people using Social Education Service and 120 elderly patients using a day care service in Seoul, Korea, were examined. We translated SF-36 version 2.0 into Korean and assessed its reliability and validity. In the results, the content validity and discriminant validity were found to be satisfactory. Cronbach's alpha coefficients ranged from 0.9298 to 0.9383. The test-retest reliability coefficients ranged from 0.710 to 0.895. In addition, the utility was examined by testing the correlation between the health-related QOL and related factors (sex, age, motor function, ability of daily life) among the elderly people. The present findings suggested that the Korean version of SF-36 would be useful as a measure of the health related QOL in Korean elderly people.
