摘　　要：目的评价老年人营养量表中文版（NUFFE-CHI）的信效度,为老年人提供营养不良筛查工具。方法2013年4—7月,在锦州市凌河区、太和区及古塔区各社区设立问卷调查点,选择锦州市≥60周岁的社区老年人701例为研究对象。将老年人营养量表（NUFFE）翻译成中文,得到NUFFE-CHI,对社区老年人进行问卷调查。采用SPSS 17.0与AMOS 17.0软件进行数据处理,计算NUFFE-CHI的信效度指标。结果 NUFFE-CHI内部一致性Cronbach＇sα系数为0.65,分半信度为0.67,重测信度为0.80（P〈0.001）。NUFFE-CHI各条目得分均与总分呈正相关（P〈0.05）,内容效度指数（CVI）为0.827。经探索性因素分析得到6个公因子,累计解释了57.65%的方差;NUFFE-CHI各条目共同度为0.397～0.668;验证性因素分析结果显示,NUFFE-CHI六因素模型的拟合优度指数（GFI）、调整拟合优度指数（AGFI）均≥0.900,近似误差均方根（RMSEA）〈0.05;NUFFE-CHI未标准化六因素模型回归系数为0.46～8.85,标准化六因素模型回归系数为0.22～0.75。结论 NUFFE-CHI具有较好的信效度,可以作为一种营养不良筛查工具应用于中国社区老年人群。Objective To evaluate the reliability and validity of Nutritional Form for the Elderly（Chinese version）（NUFFE-CHI） to provide tools for elderly malnutrition screening.Methods NUFFE-CHI was used to carry out a questionnaire in 701 community elderly（≥60 years old） in 3 communities in Jinzhou from April to July 2013.The indicators of reliability and validity of NUFFE-CHI were calculated.Results The internal consistency Cronbach＇s α of NUFFE-CHI was 0.65,split-half reliability was 0.67 and test-retest reliability was 0.80（P〈0.001）.Item-to-total correlation analysis shows that each item scores was positively correlated with total score（P〈0.05）,the content validity index（CVI） was 0.827.Six common factors from exploratory factor analysis explained cumulatively 57.65% of variance;the communalities of items of NUFFE-CHI were 0.397-0.668.By confirmatory factor analysis,the goodness of fit index（GFI）,adjusted goodness of fit index（AGFI） of NUFFE-CHI 6-factor model were both≥0.900,root mean square error approximation（RMSEA）〈0.05;NUFFE-CHI nonstandardized 6-factor model regression coefficients were 0.46-8.85,the standardized were 0.22-0.75.Conclusion NUFFE-CHI is of good reliability and validity,which can be used as a tool for elderly malnutrition screening in community elderly population.
