The COVID-19 mitigation measures require a fundamental shift in human behavior. The present study assesses what factors influence Americans to comply with the stay at home and social distancing measures. It analyzes data from an online survey, conducted on April 3, 2020, of 570 participants from 35 states that have adopted such measures. The results show that while perceptual deterrence was not associated with compliance, people actually comply less when they fear the authorities. Further, two broad processes promote compliance. First, compliance depended on people’s capacity to obey the rules, opportunity to break the rules, and self-control. As such, compliance results from their own personal abilities and the context in which they live. Second, compliance depended on people’s intrinsic motivations, including substantive moral support and social norms. This paper discusses the implications of these findings for ensuring compliance to effectively mitigate the virus.

In response to the COVID-19 pandemic, the Dutch government has introduced an "intelligent lockdown" with stay at home and social distancing measures. The Dutch approach to mitigate the virus focuses less on repression and more on moral appeals and self-discipline. This study assessed what factors influence whether Dutch people comply with the measures. We analyzed data from an online survey (N = 568) conducted between April 7-14. The overall results showed that reported compliance was high. Analyzing what shaped such compliance, shows that the the Dutch approach has to some extent worked as hoped in practice. Repression did not play a significant role in compliance, while intrinsic (moral and social) motivations promoted compliance. Yet appeals on self-discipline did not work for everyone, and people who reported more impulsivity were more likely to violate the rules. In addition, compliance was lower for people who lacked the practical capacity to follow the measures and for those who have the opportunity to break the measures. Sustained compliance, therefore, relies on support to aid people to maintain social distancing and restrictions to reduce opportunities for unsafe gatherings. These findings suggest several important practical recommendations for combating the COVID-19 pandemic.

The COVID-19 pandemic has greatly influenced daily life all over the world. The present study assesses what factors influenced inhabitants of the United Kingdom to comply with lockdown and social distancing measures. It analyses data from an online survey, conducted on April 6-8, 2020, amongst a nationally representative sample of 555 participants who currently reside in the UK. The results show that compliance depended mostly on people's capacity to comply with the rules, and the normative obligation they feel to obey the law. As such, compliance was not associated with deterrence or obedience out of fear, but rather with people's practical abilities and intrinsic motivation to comply. The paper discusses policy implications for effective mitigation of the virus.

A crucial question in the governance of infectious disease outbreaks is how to ensure that people continue to adhere to mitigation measures for the longer duration. The present paper examines this question by means of a set of cross-sectional studies conducted in the United States during the COVID-19 pandemic, in May, June, and July of 2020. Using stratified samples that mimic the demographic characteristics of the U.S. population, it seeks to understand to what extent Americans continued to adhere to social distancing measures in the period after the first lockdown ended. Moreover, it seeks to uncover which variables sustained (or undermined) adherence across this period. For this purpose, we examined a broad range of factors, relating to people’s (1) knowledge and understanding of the mitigation measures, (2) perceptions of their costs and benefits, (3) perceptions of legitimacy and procedural justice, (4) personal factors, (5) social environment, and (6) practical circumstances. Our findings reveal that adherence was chiefly shaped by three major factors: respondents adhered more when they (a) had greater practical capacity to adhere, (b) morally agreed more with the measures, and (c) perceived the virus as a more severe health threat. Adherence was shaped to a lesser extent by impulsivity, knowledge of social distancing measures, opportunities for violating, personal costs, and descriptive social norms. The results also reveal, however, that adherence declined across this period, which was partly explained by changes in people’s moral alignment, threat perceptions, knowledge, and perceived social norms. These findings show that adherence originates from a broad range of factors that develop dynamically across time. Practically these insights help to improve pandemic governance, as well as contributing theoretically to the study of compliance and the way that rules come to shape behavior.
