脑卒中后康复信心测量问卷中文版信效度研究

Reliability and validity of Chinese version of the confidence after stroke measure questionnaire

目的评价脑卒中后康复信心测量问卷（the confidence after stroke measure，CaSM）中文版的信效度。方法将CaSM译成中文，对280名脑卒中患者进行调查，运用SPSS20．0和AMOS17．0软件进行统计分析。结果CaSM中文版量表总Cronbach’s α系数为0．974，3个维度的Cronbach’sα系数分别为0．941，0．954，0．908，Guttman分半信度为0．960，重测信度为0．891；条目一总分呈显著正相关（r=0．542～0．901，P〈O．05），I-CVI为0．830～1．000，S—CVI／UA为0．815，S-CVI／AVe为0．969。探索性因子分析共提取自我信心、积极态度、社交信心三个公因子，条目共同度为0．468—0．828，KMO值为0．938，累积方差贡献率为70．731％；验证性因子分析显示该量表模型拟合良好（χ^2／df=2．591，RMSEA=0．077，GFI=0．930，AGFI=0．902，TLI=0．927，IFI=0．943，NFI=0．911，CFI=0．943），标准化回归系数为0．48～0．90。效标关联显示中文版CaSM与脑卒中自我效能问卷（SSEQ）总分呈正相关（r=0．781，P〈0．01）。结论中文版CaSM信效度良好，可用于脑卒中患者对自身疾病康复信心水平的评估。

Objective To examine the reliability and validity of the Chinese version of the confidence after stroke measure（CaSM）. Methods The reliability and validity of the Chinese version of CaSM were tested among 280 stroke patients in Jinzhou city. All the data were analyzed by SPSS20. 0 and AMOS17.0. Results The Cronbach＇s α of the overall scale was 0.974, and that of subscales were 0.941, 0.954,0.908, the Guttman split-half coefficient was 0.960, the retest reliability was 0.891.All the entries-total scores were significantly positive related （r= 0.542-0.901 ,P〈0.05）, I-CVI were 0.830-1.000, S-CVI/UA was 0.815 and S-CVI/Ave was 0.969.Three-factors （self-confidence, positive attitude, social confidence）models were got by using exploratory factor analysis and the communalities of the items were 0.468-0.828.KMO was 0.938, explaining 70. 731% variance. Confirmatory factors analysis showed that the fit indices were χ^2/df= 2.5918, RMSEA = 0.077, GFI = 0.930, AGFI = 0.902, TLI = 0.927, IFI = 0.943, NFI = 0.911, CFI = 0.943, standardized regression coefficient were 0.48-0.90.The criterion-related validity between CaSM and SSEQ was positively related （r=0.781 ,P〈0.01）. Conclusions The Chinese version of the CaSM is a reliable and valid instrument which can be used to measure the level of confidence after stroke in China.
