Cancer patients often experience severe financial distress due to the high cost of their treatment, and strategies are needed to objectively measure this financial distress. The COmprehensive Score for financial Toxicity-Functional Assessment of Chronic Illness Therapy (COST-FACIT) is one instrument used to measure such financial distress. This study aimed to translate the COST-FACIT (Version 2) [COST-FACIT-v2] instrument into traditional Chinese (COST-FACIT-v2 [TC]) and evaluate its psychometric properties.
The Functional Assessment of Chronic Illness Therapy (FACIT) translation method was adopted. The translated version was reviewed by an expert panel and by 20 cancer patients for content validity and face validity, respectively, and 640 cancer patients, recruited from three oncology departments, completed the translated scale. Its reliability was evaluated in terms of internal consistency and test-retest reliability. Confirmatory factor analysis has been used to evaluate the one- and two-factor structures of the instrument reported in the literature. The convergent validity was examined by the correlation with health-related quality of life (HRQoL) and psychological distress. Known-group validity was examined by the difference in the COST-FACIT-v2 (TC) total mean score between groups with different income levels and frequency of health care service use.
The COST-FACIT-v2 (TC) showed good content and face validity and demonstrated high internal consistency (Cronbach's alpha, 0.86) and acceptable test-retest reliability (intraclass correlation coefficient, 0.71). Confirmatory factor analysis showed that the one- and two-factor structures of the instrument that have been reported in the literature could not be satisfactorily fitted to the data. Psychological distress correlated significantly with the COST-FACIT-v2 (TC) score (r = 0.47; p < 0.001). HRQOL showed a weak to moderate negative correlation with the COST-FACIT-v2 (TC) score (r = - 0.23 to - 0.46; p < 0.001). Significant differences were seen among the COST-FACIT-v2 (TC) scores obtained in groups of different income level and frequency of health care service use.
The COST-FACIT-v2 (TC) showed some desirable psychometric properties to support its validity and reliability for assessing cancer patients' level of financial toxicity.
癌症患者由于治疗费用高昂，经常面临严重的经济困境，因此需要策略来客观衡量这种经济困境。综合财务毒性功能评估慢性疾病治疗量表（COST-FACIT）是一种用于衡量这种财务困境的工具。本研究旨在将 COST-FACIT（第 2 版）[COST-FACIT-v2]量表翻译成繁体中文（COST-FACIT-v2[TC]），并评估其心理测量特性。
采用功能评估慢性疾病治疗量表（FACIT）的翻译方法。经专家小组和 20 名癌症患者对翻译版本进行内容有效性和表面有效性评估，然后招募了来自三个肿瘤科的 640 名癌症患者完成了翻译量表。从内部一致性和重测信度方面评估其可靠性。采用验证性因子分析评估文献中报道的仪器的单因素和双因素结构。通过与健康相关的生活质量（HRQoL）和心理困扰的相关性来检验其收敛效度。通过不同收入水平和医疗服务使用频率组之间的 COST-FACIT-v2（TC）总分差异来检验其已知组有效性。
COST-FACIT-v2（TC）显示出良好的内容和表面有效性，具有较高的内部一致性（Cronbach's alpha，0.86）和可接受的重测信度（组内相关系数，0.71）。验证性因子分析表明，文献中报道的仪器的单因素和双因素结构不能令人满意地拟合数据。心理困扰与 COST-FACIT-v2（TC）评分显著相关（r=0.47;p<0.001）。HRQoL 与 COST-FACIT-v2（TC）评分呈弱至中度负相关（r=-0.23 至-0.46;p<0.001）。在不同收入水平和医疗服务使用频率组之间，COST-FACIT-v2（TC）评分存在显著差异。
COST-FACIT-v2（TC）具有一些理想的心理测量特性，可支持其有效性和可靠性，用于评估癌症患者的财务毒性水平。
