在日本，只有少数跨文化适应的、国际上使用的骨科患者自我评估结果评分可用。此外，膝关节骨关节炎(OA)的高发病率表明，需要对日本人群广泛使用的膝关节损伤和骨关节炎结果评分(KOOS)等有效的结果衡量标准。本研究的目的是提供一个跨文化适应和有效的Koos问卷，以便在涉及日本患者的国内和国际临床项目中进一步使用。日本Koos是根据标准的跨文化适应指南开发的。为了验证，Koos在58名被诊断为OA的患者身上进行了测试。信度检验采用组内相关系数(ICC)。内部一致性或同质性使用Cronbach‘s Alpha进行评估。结构效度通过量化日本OKS和SF-36问卷之间的相关系数来评估，翻译和预试阶段没有遇到重大困难。所有五个Koos分量表都表现出良好的重复性，ICC值大于0.85，与Cronbach‘s Alpha值在0.90左右有很高的内部一致性，Spearmann’s系数超过0.50，表明Koos分量表与OKS以及SF-36的大部分已建立的分量表具有良好的相关性。我们验证的日本KoOS是一个可靠和稳定的结果测量方法，为国内和国际专注于膝关节骨关节炎患者评估的临床项目提供了有价值的基础。
In Japan, only few cross-culturally adapted, internationally used orthopaedic patient self-assessed outcome scores are available. In addition, the high incidence of knee osteoarthritis (OA) suggests the need for validated outcome measures such as the widely used Knee Injury and Osteoarthritis Outcome Score (KOOS) for Japanese populations. The purpose of this study was to provide a cross-culturally adapted and validated KOOS questionnaire for further use in national and international clinical projects involving Japanese patients.The Japanese KOOS was developed according to the standard cross-cultural adaptation guidelines. For validation, the KOOS was tested on 58 patients diagnosed with OA. Reliability was tested using the intraclass correlation coefficient (ICC). Internal consistency or homogeneity was assessed using Cronbach's alpha. Construct validity was evaluated by quantifying the correlation between the KOOS and the Japanese OKS and SF-36 questionnaires with Spearmann's correlation coefficients.No major difficulties were encountered during the translation and pre-testing stages. All five KOOS subscales showed adequate reproducibility with ICC values greater than 0.85, high internal consistency with Cronbach's alpha values around 0.90, and high Spearmann's coefficients over 0.50 signifying good correlation between the KOOS subscales and the OKS as well as the majority of the established subscales of the SF-36. No floor and ceiling effects were observed for the five subscales.Our validated Japanese KOOS is a reliable and stable outcomes measure that provides a valuable basis for national and international clinical projects focusing on patient-based assessments in knee OA.
