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 pro-vide 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 3 857 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 vol-ume,and factor load of each item,the nutrition literacy scale for cancer survivors was developed,consisting of 4 dimen-sions and 21 items.The total Cronbach's α coefficient of the scale was 0.83,and the results of the second-order confirm-atory factor analysis also indicated a good model fit(x2/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 lit-eracy scale for cancer survivors exhibits good reliability and validity,making it suitable for assessing the nutritional litera-cy level of cancer survivors and related research.
