Reliability of a Thai version of the SF-36 questionnaire has never been reported. The objective of this study was to determine the reliability of a Thai version of the SF-36 questionnaire in cardiac patients. We developed a Thai version of the SF-36 questionnaire and tested it in 212 cardiac patients. Reliability of the Thai version of the SF-36 questionnaire was assessed by internal consistency using Cronbach's Alpha statistic and inter-item correlation. We demonstrated that Cronbach's Alpha coefficient of every aspect of QOL exceeded 0.7, and all inter-item correlation exceeded 0.4. In conclusion, the Thai version of the SF-36 questionnaire is a valuable tool in assessing medical outcomes and medical research in Thai patients with cardiac disease. Whether it can be used in other diseases remains unknown.Mahidol UniversityMedicineReviewSCOPUS
