摘要
[目的]试应用新KSS评分系统并分析其应用性、反应性、信度和效度。[方法]2011年推出的new-KSS评分系统,包括全膝关节置换术前和术后的客观膝关节指标、症状、满意度、预期和各组运动时的功能等维度。作者将其翻译成中文,并对拟在本院行初次全膝关节置换的膝关节骨性关节炎连续患者在3个时间点进行评分(预约时,手术前1 d和术后3个月)。通过条目选择情况、量表完成率和天花板/地板效应分析系统的应用性。通过分析预约时和术前1 d时的2次评分的组间相关系数分析系统的重复性信度。通过分析术前1 d和术后3个月时2次评分间的Cohens d系数,分析系统的反应性。通过分析术前1 d时系统各维度评分与SF-36健康量表各维度评分间的相关性,分析系统的结构效度。[结果]52患者(68侧膝关节)参加了研究,43侧膝关节预约时完成评分量表,完成率63.23%。有14个选项在多次评分中被选择次数为0,没有观察到天花板/地板效应。术前2次评分间各维度组间相关系数0.82~0.96,具有较好的重复性信度。术前、术后2次评分各维度Cohens d系数0.83~1.56,具有较好的反应性。运动维度和满意度维度与SF-36的多数维度相关,客观、症状和预期维度与SF-36部分维度相关,系统有较好的结构效度。[结论]中文版的new-KSS评分系统具有较好的重复性、反应性和效度,但其在国内的应用性稍差。
[Objective] To test a new Knee Society scoring （KSS） system, and to analyze its feasibility, responsive- ness, reliability, and validity. [Methods] This new KSS scoring system was released in 2011 and contained objective knee in- dices, symptom, satisfaction, expectation, and knee function during various activities before and after total knee arthroplasty （TKA） . The scoring system was translated from English into Chinese and used to score consecutive patients with knee osteoar- thrifts, who planned to receive TKA for the first time in our hospital, at three time points （surgery appointment, 1 day before surgery, and 3 months after surgery） . Feasibility was evaluated by answers to items, the completion rate of the questionnaire, and ceiling and floor effects. Reproducibility was evaluated by the correlation coefficient between scores at surgery appointment and one day before surgery. Responsiveness was evaluated by Cohen＇s d coefficient between scores at one day before surgery and 3 months after surgery. Construct validity was evaluated by the correlation coefficient between scores in each domain of the new KSS scoring system and 36-item short-form health survey （SF-36） questionnaire at one day before surgery. IRe- suits] Fifty-two patients with 68 knees were enrolled in this study. Forty-three knees completed the questionnaire at surgery appointment, yielding a completion rate of 63.23%. Fourteen options were never chosen in any scoring event. Neither ceiling nor floor effects were observed. The between-group correlation coefficient for the score in each domain between two scoring events before surgery ranged between 0.82 and 0.96, showing a good reproducibility. The Cohen＇s d coefficient for the score in each do- main between scoring events before and after surgery ranged between 0.83 and 1.56, indicating a good responsiveness. The ac- tivity and satisfaction domains of the new KSS scoring system were correlated with the majority of domains of SF-36, while the objective, symptom, and expectation domains were correlated with some domains of SF-36, suggesting a good construct validity.[ Conclusions ] The Chinese version of the new KSS scor- ing system has satisfactory reproducibility, responsiveness, and validity. However, its feasibility is limited in China.
