直觉饮食量表汉化及其应用于高血压伴肥胖患者的信效度研究

Localization of the Intuitive Eating Scale-2 and evaluation of its reliability and validity for Chinese obese patients with primary hypertension

目的汉化第2版英文版直觉饮食量表(IES-2),并在高血压伴肥胖患者中进行信效度评价。方法采用Brislin翻译模式对IES-2进行翻译和回译,通过专家组讨论和预调查,对量表进行跨文化调适;采用便利抽样方法选取杭州师范大学附属医院心内科高血压伴肥胖住院患者进行调查,评价中文版IES-2(IES-2-Chi)的信效度。结果共发放问卷225份,回收205份,有效回收率为91.11%。IES-2-Chi的Cronbach′sα系数为0.947,折半信度为0.850,重测信度为0.889。卡方自由度比(χ^(2)/df)为1.318,近似误差均方根为0.040,均方根残余指数为0.053,拟合优度指数为0.902,相对适合度指标为0.982,非规范拟合指数(TLI)为0.978,递增拟合指数为0.983,规范拟合指数为0.932。结论IES-2-Chi具有较好的信度和效度,可用于预测高血压伴肥胖患者的直觉饮食现状。

Objective To translate the Intuitive Eating Scale-2(IES-2)into Chinese,and evaluate its reliability and validity for Chinese obese patients with hypertension.Methods The scale was translated and back-translated using the Brislin translation mode,and cross-cultural adaptation of the scale was performed through an expert panel discussion and the pre-survey.The convenience sampling method was used to select hospitalized obese patients with hypertension in the Department of Cardiovascular of the Affiliated Hospital of Hangzhou Normal University to evaluate the reliability and validity of the Chinese version of IES-2(IES-2-Chi).Results A total of 225 questionnaires were distributed,and 205 were recovered,with an effective recovery rate of 91.11%.The Cronbach′sɑcoefficient of IES-2-Chi was 0.947,split-half reliability was 0.850,and test-retest reliability was 0.889.The confirmatory factor analysis results showed thatχ^(2)/df was 1.318,root mean square error of approximation(RMSEA)was 0.040,root of the mean square residual(RMR)was 0.053,goodness of fit index(GFI)was 0.902,comparative fit index(CFI)was 0.982,tucker-lewis index(TLI)was 0.978,incremental fit index(IFI)was 0.983,and normed fit index(NFI)was 0.932.Conclusion The IES-2-Chi has good reliability and validity,and can be used to predict intuitive eating status in obese patients with hypertension.
