The purpose of this study was to describe the process used to translate the Malay version of the ODQ and to test The Malay version in terms of test-retest reliability and validity among Malay low back pain (LBP) volunteers. The questionnaire was translated and back-translated following WHO recommendation. The Malay version was tested for 60 patients with low back pain. Test-retest with a two-day interval was performed. Internal consistency was assessed by Cronbach’s alpha. Construct validity was assessed with correlation between the ODQ and the SF-36. Test-retest with a two-day interval was performed. Internal consistency and reliability of the Malay version of the ODQ was assessed by Cronbach’s alpha and reached 0.821. Intraclass correlation coefficient was 0.821. Test-retest correlation reliability was 0.803. The ODQ was inversely correlated with the physical functioning scale of SF-36 and with mental scales of the SF-36. The reliability and construct validity of the Malay version of the Oswestry Disability Questionnaire were acceptable for assessing functional status of Malay speaking patients with low back pain.
