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 a 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.
