Examining the associations of eHealth literacy (eHL) with obtaining health knowledge from websites would help to clarify the causal pathway between eHL and health knowledge. This study aimed to compare the results obtained from Internet users with high or low eHL in accessing a reputable cancer website to obtain colorectal cancer (CRC) knowledge. A total of 105 participants with high eHL and 103 participants with low eHL accessed a reputable CRC website managed by the National Cancer Center and responded to Internet-based surveys before and after accessing a website in 2012. Twelve responses to knowledge statements regarding CRC were selected based on item response theory, and the differences in correct responses of pre- and post-surveys by each eHL group were compared. Two statements showed a significant increase in correct responses in the high eHL group only: "Red meat intake is a risk factor" = 0.002), and "Obesity is a risk factor" = 0.029), whereas only one response did so in the low eHL group: "Bloody stools are a symptom" = 0.004). Low eHL Internet users appeared less capable of obtaining knowledge of CRC by accessing information from a reputable cancer website than high eHL Internet users.
考察电子健康素养（eHL）与从网站获取健康知识之间的关联，有助于阐明 eHL 与健康知识之间的因果关系。本研究旨在比较在访问信誉良好的癌症网站获取结直肠癌（CRC）知识时，具有高或低 eHL 的互联网用户所获得的结果。2012 年，共有 105 名 eHL 较高的参与者和 103 名 eHL 较低的参与者访问了由国家癌症中心管理的信誉良好的 CRC 网站，并在访问网站前后通过基于互联网的调查做出了回应。根据项目反应理论，选择了 12 个与 CRC 相关的知识陈述的回答，比较了每组 eHL 的前后调查中正确回答的差异。只有两个陈述在高 eHL 组中显示出正确回答的显著增加：“摄入红肉是一个危险因素”（=0.002）和“肥胖是一个危险因素”（=0.029），而只有一个陈述在低 eHL 组中显示出正确回答的增加：“血便为症状之一”（=0.004）。低 eHL 互联网用户似乎比高 eHL 互联网用户更难以通过访问信誉良好的癌症网站获取 CRC 知识。
