Screening improves the early diagnosis rate of colorectal cancer (CRC) and effectively reduces its mortality. The four-factor CRC screening belief scale is conducive to understanding the psychometric properties of screening beliefs, but no Chinese version of this scale is available. The purpose of this study was to test the psychometric properties of a Chinese version of the four-factor CRC screening belief scale in patients with cancer and their relatives.
The four-factor CRC screening belief scale was translated into Chinese based on Brislin's model. A panel review ensured the cultural adaptation and content validity of the scale. The scale was then administered to a convenience sample of 425 Chinese people recruited from July 2019 to June 2021.
Exploratory factor analysis identified the factor structure for the Chinese version of the four-factor CRC screening belief scale, including perceived barriers, perceived benefits, self-efficacy, and optimism. Confirmatory factor analysis showed that the model fits well. The scale-level content validity index was 1.0. The correlation between the Chinese version of the four-factor CRC screening belief scale and the CRC health belief model scale was statistically significant ( = 0.831, < 0.01). McDonald's omega coefficients for the entire scale were 0.939 and 0.774-0.948 for the four subscales. The translated scale had test-retest reliability of 0.719 and split-half reliability of 0.646.
The Chinese version of the four-factor CRC screening belief scale showed adequate reliability and validity. The translation and validation of psychosocial assessment tools for CRC screening across languages, cultures, and countries will contribute to further international research collaborations and the improvement of the prospects for the prevention and care of CRC.
筛查可提高结直肠癌（CRC）的早期诊断率并有效降低其死亡率。四因素CRC筛查信念量表有助于了解筛查信念的心理测量特性，但尚无该量表的中文版。本研究旨在测试中文版四因素CRC筛查信念量表在癌症患者及其亲属中的心理测量特性。
基于布里斯林模型将四因素CRC筛查信念量表翻译成中文。专家小组审查确保了该量表的文化适应性和内容效度。然后将该量表施用于2019年7月至2021年6月招募的425名中国人的便利样本。
探索性因素分析确定了中文版四因素CRC筛查信念量表的因素结构，包括感知障碍、感知益处、自我效能和乐观主义。验证性因素分析表明模型拟合良好。量表水平的内容效度指数为1.0。中文版四因素CRC筛查信念量表与CRC健康信念模型量表之间的相关性具有统计学意义（= 0.831，<0.01）。整个量表的麦克唐纳ω系数为0.939，四个子量表的系数为0.774 - 0.948。翻译后的量表重测信度为0.719，分半信度为0.646。
中文版四因素CRC筛查信念量表显示出足够的信度和效度。跨语言、文化和国家对CRC筛查的社会心理评估工具进行翻译和验证，将有助于进一步开展国际研究合作，并改善CRC预防和护理的前景。
