COVID-19: Risk perception, risk communication, and behavioral intentions

Area of Science:

• Psychology
• Public Health
• Behavioral Science

Background:

• Compliance with public health guidelines like mask-wearing is crucial for controlling pandemics.
• Understanding the severity and likelihood of health risks is key to compliance.
• Complex pandemic statistics can be misunderstood, hindering effective public response.

Purpose of the Study:

• To investigate how different formats of risk communication (numeric vs. gist) affect perceptions and behavioral intentions related to COVID-19.
• To examine the influence of age and political ideology on risk perception and compliance with protective measures.
• To assess the impact of government restrictions on engagement in risk-reduction and risk-seeking behaviors.

Main Methods:

• An online experiment was conducted with a U.S. sample.
• Participants were exposed to numeric (percentages) or gist (simplified comparisons) expressions of COVID-19 infection and mortality rates by age group.
• Data collected included perceived risk, trust, concern, behavioral intentions, and agreement with government responses.

Main Results:

• Gist-based risk communication increased mask-wearing willingness among younger participants.
• Government restrictions influenced willingness to engage in both risk-reduction and risk-seeking activities.
• Political ideology was the strongest predictor of differences; conservatives showed lower willingness for protective behaviors and policy support despite similar risk perceptions.

Conclusions:

• Simplified risk messages can be effective, particularly for specific behaviors like mask-wearing in younger demographics.
• Political ideology significantly moderates the relationship between risk perception and protective behavior, highlighting a critical challenge in public health communication.
• Future research should focus on tailoring risk communication strategies to address ideological differences and enhance compliance across diverse populations.
