摘　　要：目的检验中文版老年人营养量表（NUFFE—CHI）的信效度，为老年人营养不良筛查方法提供参考。方法将老年人营养量表译成中文版，在辽宁医学院附属第一医院对60周岁及以上的208例老年住院患者进行问卷调查，应用SPSS17．0和AMOS17．0软件对所得数据进行信效度分析。结果量表的Cronbachd系数为0．74，各条目组内相关系数（ICC）为0．84-0．96，量表ICC为0．96。条目相关性分析结果显示所有条目得分与总分均有显著相关性。条目水平的内容效度指数（I-CVl）为0．60～1．00，量表水平的内容效度指数全体一致性（S－CVI／UA）为0．87，平均量表水平的内容效度指数（S－CVI／AVe）为0．96。经探索性因子分析得到五因子模型，各条目共同度为0．460～0．793，累积解释方差64．80％的变异。对模型进行验证性因子分析得到拟合优度指数（GFI）、比较拟合指数（CFI）、增值拟合指数（IVI）≥0．900，近似误差均方根（RMSEA）〈0．08，回归系数为0．12～0．82。量表最佳临界点为13分，≥13分表示营养不良，该点灵敏度为59．6％，特异度为91．5％，受试者工作特征曲线下面积为0．823。结论NUFFE－CHI信效度良好，可用于筛查具有营养不良或营养不良风险的老年住院患者。Objective The study aimed to test the reliability and validity of the Chinese version of Nutritional Form for the Elderly （NUFFE-CHI） to provide tools for elderly malnutrition screening. Methods The Nutrition Form for the Elderly was translated into Chinese and the research was carried out among 208 old patients ≥60 years old in the First Hospital Affiliated to Liaoning Medical University in Jinzhou. The reliability and validity were analyzed by SPSS 17.0 and AMOS 17.0 software. Results The Cronbach＇s α coefficient was 0.74,the intra-elass correlation coefficients （ICC） of each item were 0.84-0.96 and the scale ICC was 0.96. Item-to-total correlation analysis showed that all of the item-to-total correlations were statistically significant. The item content validity index （I-CVI） were 0.60-1.00, the scale content validity index S-CVI/UA was 0.93 and S-CVI/Ave was 0.93. Five common factors from exploratory factor analysis explained 64.80% of the total variance, and the communalities of the items were 0.460-0.793. Confirmatory factor analysis showed the goodness of fit index （GFI）, the comparative fit index （CFI） and the incremental fit index （IFI） were all ≥ 0.900,the mean root square error approximation （RMSEA）〈0.08,the NUFFE-CHI five-factor model regression coefficients were 0.12-0.82. The best critical point was 13, I〉 13 indicated malnutrition, the sensitivity was 59.6%, the specificity was 91.5%, and area under the curve was 0.823. Conclusions NUFFE-CHI is a reliable and valid instrument which could be used for elderly malnutrition screening in elderly patients.
