脑卒中病人转移量表的汉化及信效度检验

Chineseization and reliability and validity test of the Bed⁃wheelchair Transfer Tasks Assessment Form for stroke patients

目的:汉化脑卒中病人转移量表(BTAF),并检验其信效度。方法:遵循Brislin模型对量表进行翻译,经过两轮德尔菲专家函询形成中文版BTAF量表,选择安徽省2所三级甲等医院的200例脑卒中病人,采用中文版BTAF量表进行评估,检验其信度和效度。结果:中文版BTAF量表经过因子分析最大化方差正交旋转法,共提取4个因子(准备动作、起始动作、穿脱鞋动作、转移动作)及25个条目,累计方差贡献率为74.377%,总量表的Cronbach'sα系数为0.937,总量表的折半信度为0.921;重测信度为0.908。条目水平的内容效度指数(I⁃CVI)为0.905~1.000,量表水平的内容效度指数(S⁃CVI/Ave)为0.937。验证性因子分析结果显示,25个条目对应的载荷值为0.652~0.981(P<0.01),最终模型的拟合指标:χ2/df=1.624,近似误差均方根(RMSEA)=0.062,均方根残差(RMR)=0.034,拟合优度指数(GFI)=0.822,规范拟合指数(NFI)=0.901,比较拟合指数(CFI)=0.922,增值拟合指数(IFI)=0.924,提示模型拟合效果理想。结论:中文版BTAF量表的信效度良好,可用于评价我国脑卒中病人独立完成转移的能力,为分析脑卒中病人转移障碍的影响因素、通过量表评估制定预防及干预措施提供参考依据。

Objective:To translate the Bed⁃wheelchair Transfer Tasks Assessment Form(BTAF)into Chinese and to test its reliability and validity.Methods:The scale was translated according to the Brislin model,and the Chinese version of the BTAF scale was formed after two rounds of Delphi expert correspondence.A total of 200 stroke patients from 2 tertiary grade A hospitals in Anhui province were investigated by the Chinese version of BTAF in order to test its reliability and validity.Results:Through the factor analysis to maximize variance orthogonal rotation method,a total of 4 factors(preparation action,starting action,putting on and taking off shoes,and transfer action)and 25 items were extracted from the Chinese version of BTAF.The cumulative contribution rate was 74.377%,the Cronbach's alpha coefficient of the total scale was 0.937,the split⁃half reliability of the total scale was 0.921,and the test⁃retest reliability was 0.908.The item⁃level content validity index(I⁃CVI)was 0.905⁃1.000,and the scale⁃level content validity index(S⁃CVI)/Ave was 0.937.The confirmatory factor analysis results showed that the corresponding loading values of 25 items were 0.652⁃0.981(P<0.01).The fitting index of the final model:χ2/df=1.624;root mean square error of approximation(RMSEA)=0.062;mean square Root Residual(RMR)=0.034;Goodness of Fit Index(GFI)=0.822;Normative Fit Index(NFI)=0.901;Comparative Fit Index(CFI)=0.922;Incremental Fit Index(IFI)=0.924,which indicated that the model fitting effect was ideal.Conclusions:The Chinese version of BTAF has good reliability and validity,which can be used to evaluate the independent transfer ability of stroke patients in China.It also can provide the reference for analyzing the influencing factors of transfer burden and conduct prediction and intervention measures by scales.
