Impact of Information Exposure on Perceived Risk, Efficacy, and Preventative Behaviors at the Beginning of the COVID-19 Pandemic in the United States.

This online survey took place on March 7, 2020 at the beginning of the COVID-19 outbreak in the United States. Participants (n = 698) completed an online survey in which they were asked to reflect on their mediated and interpersonal information consumption, in addition to reporting on risk perceptions, general efficacy perceptions, and preventative behaviors specific to COVID-19 in the past seven days. Participant age and chronic condition status were controlled for in all analyses. Time spent consuming news, social media, and health website information was not related to risk perceptions. Time spent on health websites predicted time spent having interpersonal conversations about COVID-19, as well as general efficacy levels. Following the Extended Parallel Process Model, perceived severity, perceived susceptibility, and general perceived efficacy predicted preventative behaviors. The vast majority of participants did report taking preventative action against COVID-19, most commonly in the form of hand washing, with many enacting stronger preventative behaviors that had yet to be recommended for the general population. Overall, mediated and interpersonal information exposure had minimal effects on perceived risk and perceived general efficacy, which in turn predicted 27.5% of the variance in preventative behavior. Efficacy was the most powerful among these predictors, and health websites, specifically governmental websites, appeared to be underutilized resources with the potential to promote efficacy during outbreaks. Further research is needed to understand causation in these relationships and to assist in successful message transmission.
