A new version of The Knee Society Knee Scoring System(©) (KSS) has recently been developed. Before this scale can be used in non-English-speaking populations, it has to be translated and validated for a particular population.
QUESTIONS/PURPOSES: We evaluated the construct and content validity, the test-retest reliability, and the internal consistency of the Dutch version of the New Knee Society KSS.
A Dutch translation was performed using a forward-backward translation protocol. We tested the construct validity of the Dutch New KSS by comparing it with the Dutch versions of the WOMAC, Knee Injury and Osteoarthritis Outcome Score (KOOS), and SF-12 scores in 137 patients undergoing total knee arthroplasty (TKA). Content validity was assessed by comparing pre- and postoperative scores and by checking floor and ceiling effects. To evaluate test-retest reliability and consistency, 47 patients completed the questionnaire a second time with a mean of 8 days interval (range, 2-20 days) between tests.
Construct validity was demonstrated because the Dutch New KSS correlated well with the Dutch WOMAC (r = -0.751; p < 0.001), Dutch KOOS (r = -0.723; p < 0.001), and Dutch SF-12 (r = 0.569; p < 0.001). There was a significant difference between pre- and postoperative scores (p < 0.001) in line with the other scores. Test-retest reliability proved excellent with an intraclass correlation coefficient between 0.73 and 0.92 depending on the domain tested. Consistency as indicated by Cronbach's alpha ranging from 0.84 to 0.96 was good to excellent.
As demonstrated by the validation procedure, the Dutch New KSS is an excellent instrument to evaluate TKA outcome in Dutch-speaking patients.
最近开发了一种新版的膝关节协会膝关节评分系统（KSS）。在该量表用于非英语国家的人群之前，必须对特定人群进行翻译和验证。
问题/目的：我们评估了荷兰版新膝关节协会 KSS 的结构和内容效度、重测信度和内部一致性。
采用正向-反向翻译方案进行荷兰语翻译。我们通过将荷兰版新 KSS 与全膝关节置换术（TKA）患者的荷兰版 WOMAC、膝关节损伤和骨关节炎结局评分（KOOS）和 SF-12 评分进行比较，来测试其结构有效性。内容有效性通过比较术前和术后评分以及检查地板和天花板效应来评估。为了评估重测信度和一致性，47 名患者在两次测试之间平均间隔 8 天（范围为 2-20 天）的情况下完成了问卷第二次测试。
结构有效性得到了证明，因为荷兰版新 KSS 与荷兰版 WOMAC（r = -0.751；p < 0.001）、荷兰版 KOOS（r = -0.723；p < 0.001）和荷兰版 SF-12（r = 0.569；p < 0.001）相关良好。术前和术后评分之间存在显著差异（p < 0.001），与其他评分一致。重测信度根据所测试的域，表现出极好的组内相关系数（ICC）在 0.73 到 0.92 之间。一致性表现良好至极好，Cronbach's alpha 为 0.84 至 0.96。
通过验证程序证明，荷兰版新 KSS 是评估荷兰语患者 TKA 结果的优秀工具。
