Abstract
The ability to share and obtain health information on social media (SM) places higher burden on individuals to evaluate the believability of such health messages given the growing nature of misinformation circulating on SM. Message features (i.e., format, veracity), message source, and an individual’s health literacy all play significant roles in how a person evaluates health messages on SM. This study assesses how message features and SM users’ health literacy predict assessment of message believability and time spent looking at simulated Facebook messages. SM users (N = 53) participated in a mixed methods experimental study, using eye-tracking technology, to measure relative time and message believability. Measures included individual health literacy, message format (narrative/non-narrative), and information veracity (evidence-based/non-evidence-based). Results showed individuals with adequate health literacy rated evidence-based posts as more believable than non-evidence-based posts. Additionally, individuals with limited health literacy spent more relative time on the source compared to individuals with adequate health literacy. Public health and health communication efforts should focus on addressing myths and misinformation found on SM. Additionally, the source of message may be equally important when evaluating messages on SM, and strategies should identify reliable sources to prevent limited health literate individuals from falling prey to misinformation.Keywords
