Abstract
Health information is increasingly conveyed to patients in digital formats, such as through health websites, patient portals, and electronic health records. However, for people to be able to process information effectively, information must be presented in a suitable format. This study examines the effectiveness of different strategies for tailoring the mode of presentation (i.e., using textual, visual, and/or audio-visual formats) on information processing outcomes among different audiences (i.e., lower vs. higher health literates; younger [25-45 years] vs. older adults [?65 years]). In an online experiment participants viewed either a customized, personalized, or non-tailored (mismatched) website based on individual preferences for presentation mode. We analysed a 3 (condition) × 2 (health literacy level) × 2 (age group) between-subjects design, examining effects on: time spent online, attention, perceived relevance, website involvement, website satisfaction, and information recall. Results (N = 490) showed that mode tailoring, by both customization and personalisation, is more effective than no tailoring. However, contingent on the outcome variable (i.e., attention, website satisfaction, information recall), or health literacy level, and age group, different tailoring strategies show different effects. Designers of digital health information should strategically consider employing personalized information modes or to have people to customize their own information materials.

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
