Abstract:

目的分析中文版经济毒性综合评分量表的信度和效度。方法对118例癌症患者采用面对面问卷调查，间隔2周后采用同一量表选取部分患者复测，利用SPSS 16.0软件统计分析量表的内外部信度、内容和结构效度。Cronbach's α系数评价量表内部一致性，Pearson相关系数作为重测信度系数评价外在信度，采用内容效度指数方法定量评价内容效度，用探索性因子分析量表的结构效度。结果量表的Cronbach's α系数为0.889，重测结果的Pearson相关系数为0.77~0.98，差异均有统计学意义（P<0.05）。中文版COST量表内容效度指数为0.82，各条目的内容效度指数为0.83~1.00；探索性因子分析提取2个公因子，其累积贡献率为68.04%，各条目在相应因子上的因子载荷均>0.60。结论中文版经济毒性综合评分量表具有较好的信度和效度，可应用于癌症人群研究。

English Abstract:

Objective To evaluate the reliability and validity of the Chinese version on comprehensive scores for financial toxicity (COST), based on the patient-reported outcome measures. Methods 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. Results 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. Conclusion The Chinese version of COST scale showed high reliability and good validity, thus can be applied to assess the financial situation in cancer patients.
