Although 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.
In 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.
SF-36-U presented good to excellent test-retest reliability for all eight domains (ICC = 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.
SF-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.
虽然 Rand 简化 36 项（SF-36）问卷是一种在临床和研究环境中评估患者生活质量的常用工具，但在根据既定指南翻译成乌尔都语版本并测试其心理测量特性之前，尚未对此进行研究。本研究旨在翻译并评估腰椎神经根病患者的 SF-36 乌尔都语版本（SF-36-U）的心理测量特性。
在这项横断面研究中，108 例腰椎神经根病患者在基线时和 7 天后填写了 SF-36-U 问卷、乌尔都语版 Oswestry 残疾指数（ODI-U）和疼痛视觉模拟量表（VAS 疼痛）。评估了两种类型的可靠性，即内部一致性和重测信度，以及三种类型的有效性，即表面、内容和结构有效性。心理测量特性与先验假设相反进行评估，且 α 水平设定为 <0.05。
SF-36-U 在所有八个领域的重测信度均为良好至优秀（ICC=0.75-0.92）。所有领域的内部一致性也可接受（Cronbach's alpha=0.73-0.90）。表面和内容有效性被认为是良好的。Pearson 相关分析显示，SF-36-U 各领域与 ODI-U（r=0.43-0.54）、VAS 疼痛（r=0.32-0.49）及其自身各问题（r=0.37-0.88）之间存在中度至高度相关性，这表明结构有效性良好。
SF-36-U 显示出可接受的心理测量特性，可作为评估讲乌尔都语的腰椎神经根病患者健康相关生活质量的可靠且有效的问卷。
