结直肠癌是乌拉圭的主要癌症死亡原因，但未能接受筛查的适龄人口不到一半。由于缺乏评估影响该人群筛查决策的心理社会因素的措施，相关研究受到了限制。为了填补这一空白，我们报道了基于健康素养模型的乌拉圭结直肠癌认知量表（Colorectal Cancer Literacy Scale-Uruguay Version）的研发和心理测量的验证。我们根据现有文献开发了一个项目库，征求了专家的意见，并与社区参与者和医疗保健提供者进行了焦点小组讨论。在修订后，我们对405名全国社区样本参与者进行了心理测量验证。通过探索因子分析，我们确定了四个因素，基于理论和实际原因将其合并为两个因素，即对癌症预防的态度和对癌症的态度、信念和情绪。鉴于其独特的焦点，我们单独考察了第三个因子，即对结直肠癌的认知。随后，我们使用剩余的样本参与者进行了根据拉希测量理论的验证性因子分析，以进一步评估量表的心理测量属性。最终得到的44个项目的量表表现出良好的模型拟合度，具有足够的EAP可靠性和良好的初始鉴别效度。在其他量表可用时，应进行进一步的标准关联效度分析。乌拉圭结直肠癌认知量表（Colorectal Cancer Literacy Scale-Uruguay Version）是一个基于理论的工具，可以揭示风险人群中的障碍和促进因素。论文对于理论、研究和实践的意义进行了讨论。版权所有 © 2023 Buki、Reich、Wang、Sanabia、Larrosa、Sologaistoa和Blanco。

Colorectal cancer is a leading cause of cancer death in Uruguay, yet less than half of the eligible population is up to date with screenings. Research is hampered because no measures exist to assess psychosocial factors that influence screening decisions in this population. To address this gap, we report on the development and psychometric validation of the Colorectal Cancer Literacy Scale-Uruguay Version, a scale based on the health literacy model. We developed an item pool based on the extant literature, obtained feedback from experts, and conducted focus groups with community participants and health care providers. After revision, we conducted a psychometric validation with a national community sample of 405 participants. Through an exploratory factor analysis, we identified four factors that were collapsed into two for theoretical and pragmatic reasons, representing (a) disposition toward cancer prevention and (b) attitudes, beliefs, and emotions about cancer. A third factor, knowledge about colorectal cancer, was examined separately given its distinct focus. Subsequently, we conducted a confirmatory factor analysis with the remaining sample participants using Rasch measurement theory for validation purposes and to further assess the scales' psychometric properties. The resulting 44-item scale presented a good model fit with adequate EAP reliabilities and good initial discriminant validity. Further criterion-related validity analyses should be performed when additional measures are available. The Colorectal Cancer Literacy Scale-Uruguay Version is a theoretically based measure that can bring to light barriers and facilitative factors in an underscreened population at risk. Implications for theory, research, and practice are discussed.Copyright © 2023 Buki, Reich, Wang, Sanabia, Larrosa, Sologaistoa and Blanco.
