结直肠癌患者营养相关症状评估量表的编制及信效度检验

Development of the Nutrition Impact Symptom Scale for Colorectal Cancer Patients and its reliability and validity

目的编制结直肠癌患者营养相关症状评估量表。方法以不悦症状理论为指导,通过文献研究法、专家函询法、小样本预调查形成量表初稿。于2023年3—5月采用便利抽样法选取在江苏省肿瘤医院就诊的127例结直肠癌患者为研究对象进行量表的项目分析与信效度检验。结果最终形成的量表包括5个维度共17个条目。量表内容效度指数为0.83~1.00,平均内容效度指数为0.97,探索性因子分析提取5个公因子,累计方差贡献率为61.622%。量表总的Cronbach'sα系数为0.708,各维度的Cronbach'sα系数分别为0.762、0.642、0.625、0.510、0.644,量表的折半信度系数为0.824。结论结直肠癌患者营养相关症状量表编制过程科学,信效度良好,可用于评估结直肠癌患者营养相关症状体验。

Objective To develop the Nutrition Impact Symptom Scale for Colorectal Cancer Patients.Methods Guided by the theory of unpleasant symptoms,the initial draft of the scale was formed through literature research,expert consultation,and small sample pre-survey.From March to May 2023,convenience sampling was used to select 127 colorectal cancer patients who visited Jiangsu Cancer Hospital as the research subject for item analysis and reliability and validity testing of the scale.Results The final scale consisted of five dimensions and a total of 17 items.The content validity index of the scale was from 0.83 to 1.00,with an average content validity index of 0.97.Exploratory factor analysis extracted five common factors,and the cumulative variance contribution rate was 61.622%.The total Cronbach'sαcoefficient of the scale was 0.708,and the coefficients for each dimension were 0.762,0.642,0.625,0.510,and 0.644,respectively.The half reliability coefficient of the scale was 0.824.Conclusions The development process of the Nutrition Impact Symptom Scale for Colorectal Cancer Patients is scientific,with good reliability and validity,and can be used to evaluate the nutrition impact symptom of colorectal cancer patients.
