Cultural issues in using the SF-36 Health Survey in Asia: results from Taiwan.
BACKGROUND
The feasibility of using the SF-36 in non-Western cultures is important for researchers seeking to understand cultural influences upon health status perceptions. This paper reports on the performance of the Taiwan version of the SF-36, including the implications of cultural influences.


METHODS
A total of 1191 volunteered subjects from the general population answered the translated SF-36 Taiwan version, which was developed following IQOLA project protocols.


RESULTS
Results from tests of scaling assumptions and reliability generally were satisfactory. Convergent validity, as assessed by comparing the SF-36 to a mental health oriented inventory, was acceptable. Results of principal components analysis were similar to US results for many scales. However, differences were seen for the Vitality scale which was a stronger measure of mental health than physical health in Taiwan. Results are compared to those from other Asian studies and the U.S.


CONCLUSIONS
The results raise important questions regarding cultural influences in international studies of health status assessment. Further research into the conceptualization and components of mental health in Asian countries is warranted.
