This study aimed to validate the SF-12v2 in Iran. Methods A random sample of the general population aged 18 years and over living in Tehran Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses EFA and CFA . Results In all 3685 individuals were studied 1887male and 1798 female . Internal consistency for both summary measures was satisfactory. Cronbach s a for the Physical Component Summary PCS-12 was 0.87 and for the Mental Component Summary MCS-12 it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status P 0.05 . Furthermore as hypothesized the physical functioning role physical bodily pain and general health subscales correlated higher with the PCS-12 while the vitality social functioning role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure physical and mental health that jointly accounted for 59.9 of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure physical and mental health . Conclusion Although the findings could not be generalized to the Iranian population overall the findings suggest that the SF-12v2 .
