Background: Colorectal cancer is an important public health problem worldwide. Although progress in screening and treatment has considerably improved the prognosis in the developed world, in developing countries colorectal cancer mortality rate remains relatively high. Colorectal cancer screening literacy is an important initial step in overcoming this problem. Development of a validated assessment instrument is therefore important for implementation of appropriate health education programs to facilitate early detection. Objectives: This study focused on generation and validation of a colorectal cancer screening literacy scale for Thai people in northeastern Thailand. Methods: This methodological study was carried out in two phases: (1) literature reviews and semi-structured interviews were used to select items, then the content and face validity were checked; and (2) a confirmatory factor analysis (CFA) was conducted to test construct validity and reliability. A self-administered questionnaire was used to collect data from Thai people aged 50- 65 in June 2017. Results: For the total of 400 participants who responded (response rate 100 %), the age ranged from 50 to 65 years old (mean = 57.3, SD = 4.616). The colorectal cancer screening literacy scale was designed to include 6 domains and it was shown to have good internal consistency, and CFA demonstrated the model to fit data adequately (Chi-squared/degree of freedom = 1.079, p = 0.061, CFI = 1.00, GFI = 0.93, AGFI = 0.91, RMSEA = 0.014 and SRMR = 0.036). The final version of its, consisting of 57 items across the 6 domains covering key aspects of colorectal cancer screening literacy, demonstrated good psychometric properties for this population. Conclusions: Use of the colorectal cancer screening literacy scale in Thai people could lead to improved educational programs for optimizing colorectal cancer screening.
结直肠癌是全球一个重要的公共卫生问题。尽管筛查和治疗方面的进展已显著改善了发达国家的预后，但在发展中国家，结直肠癌死亡率仍然相对较高。结直肠癌筛查知识是克服这一问题的重要第一步。因此，开发一种经过验证的评估工具对于实施适当的健康教育计划以促进早期发现至关重要。目的：本研究聚焦于为泰国东北部人群生成并验证一种结直肠癌筛查知识量表。方法：本方法学研究分两个阶段进行：（1）通过文献综述和半结构化访谈来选择条目，然后检查内容效度和表面效度；（2）进行验证性因子分析（CFA）以检验结构效度和信度。2017年6月，采用自填式问卷从50 - 65岁的泰国人群中收集数据。结果：在总共400名做出回应的参与者中（回应率100%），年龄范围为50至65岁（均值 = 57.3，标准差 = 4.616）。结直肠癌筛查知识量表设计为包含6个领域，显示出良好的内部一致性，CFA表明模型与数据拟合良好（卡方/自由度 = 1.079，p = 0.061，CFI = 1.00，GFI = 0.93，AGFI = 0.91，RMSEA = 0.014，SRMR = 0.036）。其最终版本由涵盖结直肠癌筛查知识关键方面的6个领域中的57个条目组成，对该人群显示出良好的心理测量学特性。结论：在泰国人群中使用结直肠癌筛查知识量表可能会改进优化结直肠癌筛查的教育计划。
