互联网可能是传播结直肠癌(CRC)筛查信息的关键渠道。然而，除了写作风格以外，很少有研究系统地研究与互联网上癌症信息阅读困难有关的因素。在本次研究中，我们评估了19个CRC网站的阅读难度，并使用烟雾可读性公式和材料适宜性评估工具对选定网站中包含CRC筛查或预防信息的页面进行了评估，平均雾霾阅读等级为12.8。SAM的结果指出了这些网站的共同问题，包括(1)缺乏对关键思想的审查；(2)对关键信息的插图使用不足；(3)拥挤的布局和冗长的线条；(4)字体小，缺乏突出关键内容的提示；以及(5)缺乏互动功能。许多提供CRC信息的网站对于普通美国成年人来说可能太难了，对于识字有限的成年人来说也太难了。互联网可以支持学习的独特功能没有得到利用。互联网可以成为教育个人了解《儿童权利公约》的有力工具，但困难内容的障碍必须与访问障碍一起解决。
The Internet could be a key channel for disseminating information about colorectal cancer (CRC) screening. Little research, however, has systematically examined factors other than writing style related to the reading difficulty of cancer information on the Internet. In the present study we assessed the reading difficulty of 19 CRC Web sites.We assessed pages within selected sites containing information on CRC screening or prevention using the SMOG readability formula and Suitability Assessment of Materials instrument.The average SMOG reading grade level was 12.8. The SAM results indicated common problems with the sites, including (1) lack of review of key ideas; (2) insufficient use of illustrations for key messages; (3) crowded layout and long line lengths; (4) small type size and lack of cues to highlight key content; and (5) lack of interactive features.Many Web sites providing CRC information may be too difficult for the average American adult and much too difficult for adults with limited literacy. The unique features of the Internet that could support learning are not being utilized. The Internet could be a powerful tool for educating individuals about CRC, but the barrier of difficult content must be addressed along with access barriers.
