摘要
目的:基于经典测量理论(CTT)和项目反应理论(IRT)对经济毒性量表(COST-PROM)在心力衰竭患者中应用的综合条目评价。方法:方便抽样选取2023年7月—10月在湖北省2家三甲医院的206例心衰病人进行调查,使用CTT的相关系数、变异度、因子分析及Cronbach'sα系数及IRT中区分度、难度和信息量进行条目评价。结果:COST-PROM条目内容效度指数为1.000;CTT结果显示条目与总量表得分的相关系数为0.823~0.958;变异度为1.228~1.388;因子分析所有条目均≥0.5;总量表Cronbach'sα系数为0.973。11个条目均满足4种统计学方法;IRT结果显示11个条目区分度在2.77~11.554之间;各难度系数为-0.902~1.615;平均信息量均>1.455。结论:量表所有条目性能较高具有较好代表性,是有效评估心衰患者经济毒性的评估工具。
Objective:To comprehensive scores for financial toxicity based on the patient-reported outcome measure(COST-PROM)in heart failure patients based on classical test theory(CTT)and item response theory(IRT)and to square an assessment tool for economic toxicity in heart failure patients.Methods:A sample of 206 patients with heart failure in two tertiary hospitals in Hubei Province from July to October 2023 was selected for the survey,and the entries were evaluated using the correlation coefficient method of CTT,the method of variability,the factor analysis method,and the Cronbach'sαcoefficients and the differentiation,difficulty,and informativeness of the IRT.Results:The content validity index for COST-PROM entries was 1.000;CTT results showed correlation coefficients between entries and total scale scores ranging from 0.823 to 0.958;coefficients of variation ranging from 1.228 to 1.388;factor analyses with all entries≥0.5;and total scale Cronbach'sαcoefficient of 0.973.All 11 entries satisfied all 4 statistical methods;IRT results showed that the 11 entries discriminated between 2.77 and 11.554;the respective difficulty coefficients ranged between-0.902 and 1.615;and the mean information content was>1.455 for all of them.Conclusion:The high performance and representativeness of all items in the scale make it a valid assessment tool for evaluating economic toxicity in heart failure patients.
