自主功能指数量表的汉化及信效度检验

Chinese version of autonomic function index and its reliability and validity test

目的:汉化自主功能指数量表(IAF)并在糖尿病病人中应用进行信效度检验。方法:通过Brislin模式对IAF进行跨文化调试,并在442例糖尿病病人中进行信效度检验。结果:中文版IAF量表包括3个维度,共15个条目,各维度与量表总分之间的相关系数为0.487~0.722。量表条目水平的内容效度指数为0.830~1.000,量表水平的内容效度指数为0.978。探索性因子分析共提取3个公因子,累积方差贡献率为66.073%;验证性因子分析中,χ^(2)/ν=2.448,近似误差均方根为0.079,其他指标均达到标准,模型适配度良好。量表的总Cronbach'sα系数为0.888,各维度Cronbach'sα系数为0.789~0.914。量表重测信度为0.839,各维度重测信度为0.737~0.922。量表折半信度为0.751,各维度折半信度为0.726~0.893。结论:中文版IAF量表信效度良好,可作为糖尿病病人自主性功能的评估工具。

Objective:To test the reliability and validity of the Chinese Index of Autonomous Functioning(IAF)and its application in diabetes patients.Methods:IAF was cross-cultural debugged by Brislin model,and its reliability and validity were tested in 442 diabetes patients.Results:There are 3 dimensions and 15 items in the Chinese version of IAF scale,and the correlation coefficient between each dimension and the total score of the scale was 0.487‐0.722.The I‐CVI of the scale was 0.830‐1.000,and the S‐CVI was 0.978.Three common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 66.073%;In the confirmatory factor analysis,χ^(2)/ν=2.448,RMSEA=0.079,and other indicators reached the expression,indicating that the model has a good adaptability.For the total scale,the Cronbach'sαcoefficient was 0.888,Cronbach'sαcoefficient was 0.789‐0.914.The test‐retest reliability of the scale was 0.839,and the test‐retest reliability of each dimension was 0.737‐0.922.The half reliability of the scale was 0.751,and the half reliability of each dimension was 0.726‐0.893.Conclusion:The Chinese version of IAF scale has good reliability and validity,and can be used as a tool to evaluate the autonomic function of patients with diabetes.
