To evaluate the reliability and validity of the Chinese version on comprehensive scores for financial toxicity (COST), based on the patient-reported outcome measures. A total of 118 cancer patients were face-to-face interviewed by well-trained investigators. Cronbach's α and Pearson correlation coefficient were used to evaluate reliability. Content validity index (CVI) and exploratory factor analysis (EFA) were used to evaluate the content validity and construct validity, respectively. The Cronbach's α coefficient appeared as 0.889 for the whole questionnaire, with the results of test-retest were between 0.77 and 0.98. Scale-content validity index (S-CVI) appeared as 0.82, with item-content validity index (I-CVI) between 0.83 and 1.00. Two components were extracted from the Exploratory factor analysis, with cumulative rate as 68.04% and loading>0.60 on every item. The Chinese version of COST scale showed high reliability and good validity, thus can be applied to assess the financial situation in cancer patients.
基于患者报告结局指标，评估中文版癌症经济毒性综合评分（COST）的信度和效度。共有118名癌症患者接受了训练有素的调查人员的面对面访谈。采用Cronbach's α系数和Pearson相关系数评估信度，分别采用内容效度指数（CVI）和探索性因子分析（EFA）评估内容效度和结构效度。整个问卷的Cronbach's α系数为0.889，重测结果在0.77至0.98之间。量表内容效度指数（S-CVI）为0.82，条目内容效度指数（I-CVI）在0.83至1.00之间。探索性因子分析提取出两个成分，累积贡献率为68.04%，各条目载荷>0.60。中文版COST量表具有较高的信度和良好的效度，可用于评估癌症患者的经济状况。
