Abstract:
To assess the validity and reliability of a Persian translation of the SF-36 questionnaire (version 2) as a tool for use in the general population and outpatients, we carried out a cross-sectional study of the staff of Shiraz Medical School during November 2001. Response rate was 83.6%. Internal consistency for 8 scales using Cronbach's alpha was 0.87 (minimum recommended 0.85). Construct validity was acceptable as correlation between scales and some sociodemographic characteristics was significant. The correlation coefficient between 8 scales and related principal components was also acceptable. This translation is an appropriate tool for assessing health perceptions of the population.
