摘　　要：目的膳食营养问题是影响我国癌症幸存者预后及生存质量的一个重要因素,目前的膳食评估方法因涉及内容繁多,在流行病学调查研究应用中存在诸多局限性,本研究拟编制适用于我国癌症幸存者的营养素养测评量表,为快速评估癌症幸存者存在的营养问题提供科学、适宜的工具。方法2022年1月—2023年3月,通过文献回顾、专家咨询、预调查等形成初始量表。2023年3—7月基于课题组前期建立的癌症幸存者队列,招募了3857名癌症幸存者进行调查,采用多维项目反应理论模型对量表条目进行筛选,并对筛选条目的结构效度进行验证。结果基于各条目的区分度、难度、信息量、因子负荷等信息,筛选形成包括4个维度、21个条目的癌症幸存者营养素养量表。量表的总Cronbach'sα系数为0.83,二阶验证性因子分析结果亦显示模型拟合较好(χ^(2)/df=1.769,TLI=0.986,CFI=0.988,RMSEA=0.026)。营养素养水平与癌症幸存者的生命质量相关。结论构建的癌症幸存者营养素养量表具有较好的信效度,可用于评估癌症幸存者营养素养水平及相关研究。Objective Dietary nutrition is a crucial factor affecting the prognosis and quality of life of cancer survivors in China.Current dietary assessment methods have limitations in epidemiological research due to their extensive content.Therefore,this study aims to develop a nutritional literacy assessment scale suitable for cancer survivors in China and provide a scientific and appropriate tool for assessing their nutritional issues rapidly.Methods From January 2022 to March 2023,an initial scale was formed through the literature review,expert consultation,and preliminary surveys.From March to July 2023,a total of 3857 cancer survivors were recruited based on the previously established cancer survivor cohort by the research group.The multidimensional item response theory(MIRT)model was used to select scale items,and the structural validity of the selected items was verified.Results Based on the discrimination,difficulty,information volume,and factor load of each item,the nutrition literacy scale for cancer survivors was developed,consisting of 4 dimensions and 21 items.The total Cronbach'sαcoefficient of the scale was 0.83,and the results of the second-order confirmatory factor analysis also indicated a good model fit(χ^(2)/df=1.769,TLI=0.986,CFI=0.988,RMSEA=0.026).The level of nutrition literacy was significantly correlated with cancer survivors'quality of life.Conclusion The nutrition literacy scale for cancer survivors exhibits good reliability and validity,making it suitable for assessing the nutritional literacy level of cancer survivors and related research.
