Citizens' engagement in health risk communication and preventive behaviors: the mediating role of perceived shared responsibility in the COVID-19 pandemic.

Background: In times of a public health emergency such as COVID-19, a government-centric approach may not be sufficient to contain the epidemic and ensure citizens' compliance. This study proposes a theoretical model that integrates individual-oriented, social-oriented, and community-oriented factors to predict individuals' engagement in preventive behaviors and citizen health emergency communication (CHEC). Perceived shared responsibility, which results from the communal nature of the pandemic, is tested as a mediator in the relationships between different motivations and behaviors in the context of COVID-19.
