BACKGROUND
A patient-reported outcome (PRO) tool which reflects the outcomes of patients underwent total knee arthroplasty (TKA) are important to be "ceiling effect free" which commonly used PRO tools face. Forgotten joint score-12 (FJS-12) has been proved to reduce or even free from ceiling effect. FJS-12 has been translated to different languages. The objectives of this study are to validate FJS-12 in Traditional Chinese-Hong Kong language and look for the goodness of FJS-12 still exist in this language adapted FJS-12 version.
METHODS
FJS-12 was administered to 75 patients whose majority was obese underwent TKA between September 2019 and March 2020. Patients completed 3 sets of questionnaires (FJS-12, Oxford Knee Score (OKS), and Numeric Rating Scale (NRS)) twice, 2 weeks apart. Reliability, internal consistency, responsiveness, test-retest agreement and discriminant validity were evaluated.
RESULTS
Reliability of FJS-12 showed moderate to excellent internal consistency (Cronbach's α = 0.870). Test-retest reliability of FJS-12 was good (ICC = 0.769). Bland-Altman plot showed good test-retest agreement. Construct validity in terms of correlations between FJS-12 and OKS, and FJS-12 and NRS were moderate at baseline (Pearson's coefficient r = 0.598) and good at follow-up (r = 0.879). Smallest detectable change (Responsiveness) was higher than MIC. Floor effect was none observed, and ceiling effect was low. Discriminant validity was found to have no significance. BMI (obesity) did not affect FJS-12 outcomes.
CONCLUSIONS
The Traditional Chinese-Hong Kong version of FJS-12 showed good test-retest reliability, validity, responsiveness, BMI non-specific, with no floor and low ceiling effects for patients who underwent TKA. Sub-culture differences in individual PRO tools should be considered in certain ethnicities and languages.
背景
对于接受全膝关节置换术（TKA）的患者，一种能够避免“天花板效应”的患者报告结局（PRO）工具非常重要，而常用的 PRO 工具通常都存在这种效应。遗忘关节评分-12 （FJS-12）已被证明可降低甚至消除天花板效应。FJS-12 已被翻译成多种语言。本研究的目的是验证 FJS-12 在繁体中文-香港语中的有效性，并寻找该语言改编版本的 FJS-12 是否仍具有良好的效果。
方法
2019 年 9 月至 2020 年 3 月期间，75 名肥胖的 TKA 患者接受了 FJS-12 评估。患者在 2 周的时间内完成了 3 套问卷（FJS-12、牛津膝关节评分（OKS）和数字评分量表（NRS）），各两次。评估了 FJS-12 的可靠性、内部一致性、反应性、重测信度和判别有效性。
结果
FJS-12 的可靠性显示出中度至高度的内部一致性（Cronbach's α=0.870）。FJS-12 的重测信度良好（ICC=0.769）。Bland-Altman 图显示出良好的重测信度一致性。在基线时，FJS-12 与 OKS 和 FJS-12 与 NRS 之间的结构效度中等（Pearson 相关系数 r=0.598），而在随访时良好（r=0.879）。最小可检测变化（反应性）高于 MIC。未观察到地板效应，天花板效应较低。判别有效性无统计学意义。BMI（肥胖）不影响 FJS-12 的结果。
结论
繁体中文-香港语版的 FJS-12 显示出良好的重测信度、有效性、反应性、BMI 特异性，且不存在地板效应和天花板效应，适用于接受 TKA 的患者。在某些种族和语言中，应考虑个体 PRO 工具的亚文化差异。
