ObjectiveTo描述消费者在互联网上搜索健康信息时所使用的检索和评价技术。设计定性研究，使用焦点小组，自然观察消费者在可用性实验室搜索万维网，并进行深入访谈。参与者共有21名互联网用户参加了三个焦点小组会议。17名参与者被给予了一系列的健康问题，并观察到在可用性实验室设置，同时从网络上检索健康信息，这是随后的深入interviews.Setting Heidelberg，德国.Results虽然他们的搜索技术往往是次优，互联网用户成功地找到了健康信息回答问题，平均5分42秒（中位数4分18秒）每个问题。焦点小组的参与者说，在评估网站的可信度时，他们主要关注的是来源、专业设计、科学或官方风格、语言和易用性。然而，在观察性研究中，没有参与者查看网站的任何“关于我们”部分、声明或披露声明。在搜索后的采访中，它出现了很少有参与者注意到并记住他们检索信息从哪些网站。结论需要进一步的观察性研究，以设计和评估教育和技术创新，引导消费者在网络上的高质量的健康信息。
Objectives To describe techniques for retrieval and appraisal used by consumers when they search for health information on the internet.Design Qualitative study using focus groups, naturalistic observation of consumers searching the world wide web in a usability laboratory, and in-depth interviews.Participants A total of 21 users of the internet participated in three focus group sessions. 17 participants were given a series of health questions and observed in a usability laboratory setting while retrieving health information from the web; this was followed by in-depth interviews.Setting Heidelberg, Germany.Results Although their search technique was often suboptimal, internet users successfully found health information to answer questions in an average of 5 minutes 42 seconds (median 4 minutes 18 seconds) per question. Participants in focus groups said that when assessing the credibility of a website they primarily looked for the source, a professional design, a scientific or official touch, language, and ease of use. However, in the observational study, no participants checked any "about us" sections of websites, disclaimers, or disclosure statements. In the post-search interviews, it emerged that very few participants had noticed and remembered which websites they had retrieved information from.Conclusions Further observational studies are needed to design and evaluate educational and technological innovations for guiding consumers to high quality health information on the web.
