中文版逃避与限制性饮食障碍量表在炎症性肠病患者中的信效度检验

Chinese version of the Nine-Item Avoidant/Restrictive Food Intake Disorder Scale in patients with inflammatory bowel disease: a test of reliability and validity

    摘要
  • 摘要:
    目的  检验中文版逃避与限制性饮食障碍量表(NIAS)在炎症性肠病患者中的信度和效度。
    方法  采用便利抽样的方法, 选取江苏省2所三甲医院炎症性肠病诊疗中心304例患者作为研究对象，采用一般资料调查表、NIAS、与食物相关的生活满意度量表(SWFL)对患者进行调查。对量表进行项目分析(区分度分析法、相关系数法)、总量表及分量表的信度分析(Cronbach's α系数)。采用探索性因子分析、验证性因子分析、效标关联度、聚合效度和区分效度检验量表的效度。
    结果  中文版NIAS共9个条目，包括挑食、食欲、恐惧3个维度; 验证性因素分析显示3因子模型拟合指数良好χ2/df=2.340, 近似误差均方根(RMSEA)=0.078, 标准化残差均方根(SRMR)=0.046, 增值拟合指数(IFI)=0.969, 比较拟合指数(CFI)=0.969, 规范拟合指数(NFI)=0.948, 拟合优度指数(GFI)=0.951, 非规范拟合指数(TLI)=0.951; 中文版NIAS总分和效标量表SWFL相关系数为-0.353, 具有较强的关联性; 量表各维度的聚合效度CR值为0.821~0.855, AVE分别为0.606(食欲)、0.621(挑食)、0.664(恐惧)。中文版NIAS总的Cronbach's α系数为0.82, 挑食、食欲、恐惧维度的Cronbach's α系数分别为0.87、0.71、0.92, 说明中文版NIAS具有较好的内部一致性和稳定性。
    结论  中文版NIAS具有良好的信效度，可用于评估炎症性肠病(IBD)患者的逃避与限制性饮食障碍行为。

     

    Abstract:
    Objective  To test the reliability and validity of the Chinese version of the Nine-Item Avoidant/Restrictive Food Intake Disorder Scale (NIAS) in patients with inflammatory bowel disease (IBD).
    Methods  Based on convenience sampling method, 304 patients from the Treatment Center for Inflammatory Bowel Disease of two Grade Ⅲ Level hospitals A in Jiangsu Province were selected as the research objects, and they were investigated by a general information questionnaire, NIAS, and the Satisfaction with Food-Related Life (SWFL). Item analysis (discrimination analysis, correlation coefficient) and reliability analysis of the total scale and subscales (Cronbach's α coefficient) were performed. Exploratory factor analysis, confirmatory factor analysis, criterion-related validity, convergent validity, and discriminant validity were used to test the validity of the scale.
    Results  The Chinese version of NIAS contained 9 items, including 3 subscales of picky eating, appetite and fear; the confirmatory factor analysis indicated a good construct validity in 3-factor modelχ2/df=2.340, root mean square error of approximation (RMSEA)=0.078, standardized root mean square residual (SRMR)=0.046, incremental fit index (IFI)=0.969, comparative fit index (CFI)=0.969, normed fit index (NFI)=0.948, goodness of fit index (GFI)=0.951, the Tucker-Lewis index (TLI)=0.951; the correlation coefficient between the total score of the Chinese version of NIAS and the SWFL scale was -0.353, indicating a strong correlation; the aggregated validity CR values for each dimension of the scale were 0.821 to 0.855, and the AVE values were 0.606 for appetite, 0.621 for picky eating, and 0.664 for fear. The total Cronbach's α coefficient of the Chinese version of the NIAS scale was 0.82, and the Cronbach's α coefficients for dimensions of picky eating, appetite and fear were 0.87, 0.71 and 0.92 respectively, indicating the Chinese version of the NIAS scale had good internal consistency and stability.
    Conclusion  The Chinese version of the NIAS scale has good reliability and validity, and can be used to evaluate avoidant and restrictive food intake disorder behaviors in IBD patients.
