Evidence-Based Design Principles for Web Sites Advancing eHealth Literacy

摘要

This paper reports on a study on practical design principles for Web sites aiming at the support of personal Web-based health literacy among the general population, especially adults. The principles cover the construction, presentation and management of content relating such health literacy topics as healthy food intake and the value of exercising for different groups of population. The key proposition of this study is that the design of eHealth literacy information on the Web is a special case of e-learning with respect to content delivery and focus groups. We also see adults as the members of eHealth focus groups for which we need a learner-centered approach to delivering materials. Therefore, we study seven principles in some detail with the help of a user story and following published evidence gathered by experiments relating e-learning of adults: (1) multimedia enhanced content delivery of textual information, (2) contiguity or immediate vicinity, (3) modality, (4) redundancy, (5) coherence or lean presentation, (6) personalization, and (7) segmenting.
