Understanding Online Health Information Search in Older Adults: Assessing How Search Results Influence Decision-Making

What is this Study about?

This research study examines how online search result accuracy affects people's evaluation of medical treatments, focusing on older adults with potential digital literacy challenges. Using eye-tracking, screen logging, think-aloud protocols, and interviews, the study explores how search accuracy influences judgment. The goal is to optimize trustworthy health websites and create user-friendly interfaces, enhancing health information literacy among older adults. By analyzing attention patterns, thought processes, and search result interactions, researchers aim to understand how older adults make health-related judgments online. This will inform development of search engines better suited for older adults seeking health information.
