| Abstract: | Background and aimsAlthough Rand Short Form 36-item (SF-36) questionnaire is a frequently used tool for evaluating a patient's quality of life in both clinical and research settings, but its translation into Urdu language and its psychometric properties has not been tested before, in accordance to the pre-established guidelines. This study aimed to translate and assess the psychometric properties of Urdu version of SF-36 (SF-36-U) in lumbar radiculopathy patients.MethodsIn this cross-sectional study, one hundred and eight patients of lumbar radiculopathy filled SF-36-U questionnaire, Urdu version of Oswestry Disability Index (ODI-U) and visual analogue scales for pain (VAS pain) at baseline and after 7 days. Two types of reliability i.e. internal consistency and test-retest reliability while three types of validity i.e. face, content, and construct validity were evaluated. Psychometric properties were assessed contrary to the a priori hypothesis and alpha level was kept at < 0.05.ResultsSF-36-U presented good to excellent test-retest reliability for all eight domains (ICC2,1 = 0.75–0.92). Internal consistency was also acceptable for all domains (Cronbach's alpha = 0.73–0.90). Face and content validity were found to be good. Pearson correlation revealed moderate to strong correlations of SF-36-U domains with ODI-U (r = 0.43–0.54), VAS pain (r = 0.32–0.49) and each of its own question (r = 0.37–0.88) which shows good construct validity.ConclusionSF-36-U revealed acceptable psychometric properties and is considered as a reliable and valid questionnaire for assessing the health-related quality of life in Urdu-speaking patients having lumbar radiculopathy. |
