Background: eHealth-literate consumers, consumers able to navigate and filter credible information on the Internet, are an important cornerstone of sustainable health systems in the 21^st century. Various checklists and tools for consumers to assess the quality of health information on the Internet have been proposed, but most fail to take into account the unique properties of a networked digital environment. Method: A new educational model and tool for assessing information on the Internet has been designed and pilot tested with consumers. The new proposed model replaces the “traditional” static questionnaire/checklist/ rating approach with a dynamic, process-oriented approach, which emphasizes three steps consumers should follow when navigating the Internet. FA4CT (or FACCCCT) is an acronym for these three steps: 1) Find Answers and Compare [information from different sources], 2) Check Credibility [of sources, if conflicting information is provided], 3) Check Trustworthiness (Reputation) [of sources, if conflicting information is provided]. In contrast to existing tools, the unit of evaluation is a “fact” (i.e. a health claim), rather than a webpage or website. Results: Formative evaluations and user testing suggest that the FA4CT model is a reliable, valid, and usable approach for consumers. Conclusion: The algorithm can be taught and used in educational interventions (“Internet schools” for consumers), but can also be a foundation for more sophisticated tools or portals, which automate the evaluation according to the FA4CT algorithm.
