Abstract

A laboratory study was conducted to explore whether user reviews, a common Web 2.0 feature on healthcare website, would have differential influence on younger and older adults' judgment of information credibility. We found that when credibility cues in user reviews were consistent with those in Website contents, older adults benefited more from this supplementary information than younger adults, which allowed older adults to make better credibility judgments. When credibility cues in user reviews were inconsistent with those in Website contents, older adults were less influenced by the user reviews. Results have important implications on how user reviews may facilitate credibility judgment of online health information by older adults.
