Effects of Social Media Comments on Attitude toward Vaccines: The Roles of Perceived Public Consensus and Perceived Vaccine Efficacy
Journal of Health Communication.
Abstract: This study investigated if and how exposure to Facebook comments about vaccines influences one’s attitude toward the vaccines. In this investigation, comments were examined in light of their effect on attitude toward vaccines through perceived distribution of public opinion on vaccines, and perceived vaccine efficacy was tested as a factor moderating relative effects of comments on perception of public opinion distributions. Results from an experimental study (N = 271) showed that exposure to a greater number of comments in a thread expressing (un)favorable opinions on the flu vaccine led to (un)favorable attitude toward the flu vaccine through a change in perceived distribution of public opinions on the vaccination. The indirect effect of comments on attitude toward the flu vaccine through perceived public opinion distributions was greater among participants with lower levels of perceived vaccine efficacy, while the direct effect of comments on attitude was not significant.
