Abstract

Purpose: The primary aim of this study was to translate a self-reported questionnaire (KOOS) from English to Urdu and then to see its internal consistency, agreement, test-retest reliability, and validity among primary OA knee patients.

Methodology: First, KOOS questionnaire was translated from English language to Urdu through standardized cross-cultural protocol. This translated version of KOOS was administered to 111 radiographically diagnosed primary OA knee patients at two times with 48-hour interval in-between. Cronbach's alpha, floor and ceiling effect, intraclass correlation coefficient (ICC), absolute agreement %, and Spearman correlation were used to fulfill our objectives.

Results: Average time to administer this questionnaire was 20 minutes. There was good internal consistency with Cronbach's alpha ranging from 0.7246 to 0.9139. The absolute agreement of each item between two tests ranged from 81.08% to 98.20%. Test-retest reliability was excellent ("r" ranged from 0.9673 to 0.9782). There was no ceiling effect; however less than 4% floor effect was seen in two subscales. There was significant difference that existed between different X-ray grades in all subscales meaning good content validity for disease prognosis.

Conclusion: The present results show that KOOS Urdu version is a reliable and valid measure for primary OA knee patients.

印度原发性膝骨关节炎患者乌尔都语版oos的跨文化验证。
目的:本研究的主要目的是将一份自我报告问卷(oos)从英语翻译成乌尔都语,然后观察其在原发性OA膝关节患者中的内部一致性、一致性、重测信度和效度。方法:首先,通过标准化的跨文化协议将oos问卷从英语翻译成乌尔都语。对111名经放射学诊断为原发性OA膝关节患者进行了两次翻译版oos,每次间隔48小时。Cronbach’s alpha、下限和上限效应、类内相关系数(ICC)、绝对一致性%和Spearman相关来实现我们的目标。结果:填写问卷的平均时间为20分钟。内部一致性较好,Cronbach's alpha在0.7246 ~ 0.9139之间。两种测试结果的绝对一致性在81.08% ~ 98.20%之间。重测信度极好(“r”为0.9673 ~ 0.9782)。没有天花板效应;然而,两个分量表的底效应不足4%。不同x线分级在所有亚量表上均存在显著差异,说明对疾病预后的内容效度较好。结论:KOOS乌尔都语版本是一种可靠、有效的测量原发性OA膝关节患者的方法。
