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.
What is already known on this topic
What is already known on this topic Little is known about how consumers retrieve and assess the quality of health information on the internet
Qualitative data are needed to design educational and technological innovations to guide consumers to high quality health information
What this study adds
What this study adds Users of the internet explore only the first few links on general search engines when seeking health information
Consumers say that when assessing the credibility of a site they primarily look for the source, a professional design, and a variety of other criteria
In practice, internet users do not check the “about us” sections of websites, try to find out who authors or owners of the site are, or read disclaimers or disclosure statements
Very few internet users later remember from which websites they retrieved information or who stood behind the sites
