Many people learn about smoking cessation through information on the Internet. Whether people with severe mental illnesses, who have very high rates of smoking, are able to use currently available websites about smoking cessation is unknown. The study reported here assessed whether four smoking cessation websites met usability guidelines and whether they were usable by smokers with severe mental illnesses. Four websites that appeared first on a Google search and represented an array of sponsors were selected. First, five experts rated the websites on adequacy of content in six areas and usability in 20 areas. Second, 16 smokers with severe mental illnesses performed two search tasks on the websites with researchers observing their searches and interviewing them regarding usability. One of the websites was rated by experts as acceptable for content and usability, but most of the participants were unable to navigate this website. The only website that was navigable received poor content ratings by experts. Four easily accessible websites did not meet the needs of smokers with severe mental illnesses. Although the Internet is a promising strategy to provide education about treatments, website developers must attend to the needs and capacities of multiple user groups.
许多人通过互联网上的信息了解戒烟。目前尚不清楚患有严重精神疾病、吸烟率非常高的人是否能够使用现有的戒烟网站。本报告研究评估了四个戒烟网站是否符合可用性指南，以及患有严重精神疾病的吸烟者是否能够使用这些网站。选择了在谷歌搜索中排名靠前且代表各种赞助商的四个网站。首先，五名专家根据六个方面的内容充足性和二十个方面的可用性对网站进行了评分。其次，16 名患有严重精神疾病的吸烟者在网站上执行了两个搜索任务，研究人员观察他们的搜索并就可用性对他们进行了采访。一名专家认为其中一个网站在内容和可用性方面是可以接受的，但大多数参与者无法浏览该网站。唯一可浏览的网站获得了专家较差的内容评级。四个易于访问的网站无法满足患有严重精神疾病的吸烟者的需求。尽管互联网是提供治疗教育的有前途的策略，但网站开发人员必须关注多个用户群体的需求和能力。
