弗雷曼特尔膝关节感知问卷的汉化及信效度检验

Reliability and validity of the Chinese version of Fremantle Knee Awareness Questionnaire

目的汉化弗雷曼特尔膝关节感知问卷,并在膝关节骨关节炎患者中检验其信度和效度。方法对英文版弗雷曼特尔膝关节感知问卷进行翻译、回译、跨文化调试、预调查访谈,确定中文版弗雷曼特尔膝关节感知问卷。采用便利抽样法,选取2017年6月—2020年12月安徽医科大学附属六安医院骨科收治的200例膝关节骨关节炎患者进行调查,以检验中文版弗雷曼特尔膝关节感知问卷的信效度。采用临界比值法进行条目筛选;采用内容效度指数、探索性因子分析和验证性因子分析检验问卷的效度;采用Cronbach'sα系数、分半信度系数、重测信度系数检验问卷的信度。结果中文版弗雷曼特尔膝关节感知问卷经最大方差正交旋转法共提取出2个公因子,累计方差贡献率为83.541%,包括9个条目。总问卷的Cronbach'sα系数为0.905,各维度的Cronbach'sα系数分别为0.913、0.905,总问卷的分半信度系数为0.903,总问卷的重测信度系数为0.923;平均量表水平的内容效度指数为0.906,条目水平的内容效度指数为0.885~1.000。验证性因子分析结果显示,整体模型拟合良好。结论中文版弗雷曼特尔膝关节感知问卷具有良好的信度和效度,可用于评估我国膝关节骨关节炎患者的膝关节感知觉受损症状。

Objective To translate the Fremantle Knee Awareness Questionnaire(FreKAQ)into Chinese,and test its reliability and validity in patients with knee osteoarthritis.Methods The English version of FreKAQ was translated,back translated,cross-cultural debugging,and pre survey interviews to determine the Chinese version of FreKAQ.From June 2017 to December 2020,a total of 200 patients with knee osteoarthritis admitted to the Department of Orthopedics of Lu'an Hospital of Anhui Medical University were selected by convenience sampling for investigation to test the reliability and validity of the Chinese version of FreKAQ.The critical ratio method was used to screen items,and the validity of the questionnaire was tested by content validity index,exploratory factor analysis and confirmatory factor analysis.Cronbach'sαcoefficient,split half reliability coefficient and retest reliability coefficient were used to test the reliability of the questionnaire.Results Two common factors were extracted from the Chinese version of FreKAQ by the maximum variance orthogonal rotation method,and the cumulative variance contribution rate was 83.541%,including nine items.Cronbach'sαcoefficient of the total questionnaire was 0.905,Cronbach'sαcoefficients of each dimension were 0.913 and 0.905 respectively,the split half reliability coefficient of the total questionnaire was 0.903,and the retest reliability coefficient of the total questionnaire was 0.923.The content validity index of the average scale level was 0.906,and the content validity index of the item level was 0.885 to 1.000.The confirmatory factor analysis showed that the overall model fitted well.Conclusions The Chinese version of FreKAQ has good reliability and validity,which can be used to assess the symptoms of knee awareness impairment in Chinese patients with knee osteoarthritis.
