The Impact of Trust and Risk Perception on the Acceptance of Measures to Reduce COVID-19 Cases.

The SARS-CoV-2 virus that causes COVID-19 has had a large impact on the lives of many people worldwide. At the peak of confirmed COVID-19 cases during the first wave in Switzerland (March-April 2020), we conducted a survey in the German-speaking part of the country (N = 1,585). The results suggest that the implemented measures are accepted. The survey participants are more concerned that other family members could catch the virus compared with themselves, and they are worried about its economic impact. The results suggest that how trust is measured is crucial because general trust and social trust have opposite effects on the participants' risk perceptions. People with high general trust perceive less risks associated with COVID-19 compared with people who have low general trust, and people with high social trust perceive more risks compared with people who have low social trust. The results further indicate that perceived risks are important drivers for the acceptance of the government's implemented measures to control COVID-19 and for more precautionary behavior (i.e., contact with fewer people and more hygienic behavior). Theoretical and practical implications of these findings are discussed.
