摘要 目的开发综合营养认知、食欲及机体功能等评价进行营养风险筛查的量表，并进行信效度验证。 方法 在文献回顾、患者访谈及项目组讨论的基础上确定量表维度、形成条目池，经过德尔斐专家咨询形成原始量表。选取首都医科大学附属北京世纪坛医院104例肿瘤患者进行调查，检验量表的信效度。  结果 最终形成的肿瘤患者营养认知-食欲-功能（nutrition belief-appetite-function， BAF）评估量表包括营养认知、食欲和功能指标3个维度，共13个条目。项目分析时发现各条目和总分的相关系数均＞0.3，各条目的决断值均达到预设标准，故不考虑删除条目。本量表的分半信度为0.750，各维度的分半信度为0.590～0.847；量表的Cronbachs α系数为0.806，各维度的Cronbachs α系数为0.631～0.866，营养认知和功能维度的系数未达到理想状态；量表的重测信度为0.784，各维度的重测信度为0.588～0.721。量表效度分析方面，各维度与总量表间得分的相关系数为0.539～0.890，均有显著性；结构性因子分析提取2个公因子，累计方差贡献率为56.36%，删除2个条目后得到营养认知和食欲及功能相关的两个维度；量表总分及各维度得分均与NRS 2002的显著正相关。  结论 编制的肿瘤患者BAF评估量表具有较好的信效度，可有效评估肿瘤患者的营养风险。

Abstract：ObjectiveTo develop a nutritional risk screening scale of cancer patients containing assessments of nutrition belief, appetite, and physical function, and to test its reliability and validity. MethodsThe evaluation dimensions were determined on the basis of literature review, patients interview, and research group discussion, and then the items pool was formed. The initial scale was developed by Delphi expert advisory. A total of 104 cancer patients in Beijing Shijitan Hospital were selected as subjects. The reliability and validity of the scale were tested. ResultsThe final nutrition belief-appetite-function (BAF) scale included the following 3 dimensions: nutritional belief, appetite, and physical functions, and 13 items. In the item analysis, the correlation coefficients with the total points of the scale and the Critical ratio (CR) of every item met the preset standards, without deleting any items. The split-half reliability of the BAF scale was 0.750, from 0.590 to 0.847 of each dimension. The Cronbachs α coefficient of the BAF scale was 0.806, from 0.631 to 0.866 of each dimension. The retest reliability coefficient was 0.784, from 0.588 to 0.721 of each dimension. The correlation coefficients of each dimension with the total points of the scale were from 0.539 to 0.890, and all were significant. Exploratory factor analysis (EFA) extracted 2 factors, whose cumulative contribution of variance accounted for 56.36%, and 2 items were deleted. The total points of the scale and the points of each dimension were all positively correlated with Nutritional risk screening 2002 (NRS 2002). ConclusionThe BAF scale has good reliability and validity. The scale can be used as a screening tool for evaluating the nutritional risk of cancer patients.
