Interpersonal risk communication matters more than media risk communication in its impact on individuals’ trust and preventive behaviors during COVID-19

A cross-sectional survey study from 1496 respondents was conducted to investigate how interpersonal risk communication and media risk communication foster individuals' interpersonal trust and trust in scientists during the ongoing COVID-19 pandemic. Findings reveal that interpersonal risk communication is significantly related to interpersonal trust and trust in scientists, but have no direct association with preventive behaviors. Media risk communication is significantly associated with preventive behaviors and increases individuals’ trust in scientists while having no effect on interpersonal trust. Preventive behaviors are significantly influenced by both interpersonal trust and trust in scientists. In addition, trust mediated the association between risk communication and preventive behaviors.
