The role of source and the factors audiences rely on in evaluating credibility of health information

In the wake of public relations crises of credibility such as FEMA's staged press conference in response to the California wildfires, source credibility merits increased scholarly and practitioner scrutiny in order to maximize the effectiveness of the information practitioners release, particularly when the objective is to promote action vital to public health and well-being. Through a random national telephone survey (n = 400), this research analyzes how the source itself moderates credibility as well as the criteria important to audience evaluations of credibility. Results indicate practitioners are perceived as credible sources of health information and that audiences take a rather mindful route in their evaluations of source credibility.
