The United Nations have described the outbreak of the coronavirus disease 2019 (COVID-19) as the worst global crisis since the second world war. Behavioral protective measures, such as good hand hygiene and social distancing, may strongly affect infection and fatality rates worldwide. In two studies (total N = 962), we aimed to identify central predictors of acceptance and adoption of protective measures, including sociodemographic variables, risk perception, and trust. We found that men and younger participants show lower acceptance and adoption of protective measures, suggesting that it is crucial to develop targeted health messages for these groups. Moreover, trust in politics and trust in science emerged as important predictors for the acceptance and adoption of protective measures. These results show that maintaining and ideally strengthening trust in politics and trust in science might be central for overcoming the COVID-19 pandemic.

We discuss factors that contribute to the development of trust and derive implications for effective health communication during COVID-19.
In the current psychological debate, low replicability of psychological findings is a central topic. While the discussion about the replication crisis has a huge impact on psychological research, we know less about how it impacts public trust in psychology. In this article, we examine whether low replicability damages public trust and how this damage can be repaired. Studies 1–3 provide correlational and experimental evidence that low replicability reduces public trust in psychology. Additionally, Studies 3–5 evaluate the effectiveness of commonly used trust-repair strategies such as information about increased transparency (Study 3), explanations for low replicability (Study 4), or recovered replicability (Study 5). We found no evidence that these strategies significantly repair trust. However, it remains possible that they have small but potentially meaningful effects, which could be detected with larger samples. Overall, our studies highlight the importance of replicability for public trust in psychology.
In three studies (N = 1,055), we investigated the determinants and consequences of the perception of infection risks during the early and later outbreak of COVID-19 in Germany. Individuals’ perceived COVID-19 infection risk was reasonably in line with experts’ assessment but changed over time. The probability of the rare event of getting severely sick and hospitalized was overestimated. Overestimation increased in the exponential growth phase of the pandemic and later on decreased again, showing an inverse U-shaped pattern. Individuals showed biases in their risk perception concerning overconfidence and the underestimation of exponential growth of infection cases in the early phase of the pandemic. Forecasts were more accurate after the growth curve had flattened. Risk perceptions increased with perceived dread and tended to increase with perceived control over infection, the evaluation of scientific and own knowledge about the pandemic. Approval for the introduction of stricter governmental measures and acceptance of future vaccination measures was mainly influenced by rational utilitarian factors of risk perception (probabilities and utilities of outcomes). These rational influences were mediated by dread, but dread had an additional potentially irrational effect. Adherence to governmental recommendations was mainly driven by dread and positive expected long-term consequences of the measures. To a smaller degree, adherence increased with perceived personal consequences of infection and decreased with negative expected short-term consequences of these measures. Implications for theory development are discussed and recommendations to handle virus outbreaks are derived.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
