Self-control and beliefs surrounding others' cooperation predict own health-protective behaviors and support for COVID-19 government regulations: Evidence from two European countries

In the current pandemic, both self-regulated health-protective behavior and government-imposed regulations are needed for successful outbreak mitigation. Going forward, researchers and decision-makers must therefore understand the factors contributing to individuals' engagement in health-protective behavior, and their support for government regulations. Integrating knowledge from the literatures on self-control and cooperation, we explore an informed selection of potential predictors of individuals' health-protective behaviors as well as their support for government regulations during the COVID-19 pandemic. Aiming for a conceptual replication in two European countries, we collected data in Switzerland (N = 352) and the UK before (N = 212) and during lockdown (n = 132) and conducted supervised machine learning for variable selection, followed by OLS regression, cross-sectionally and, in the UK sample, across time. Results showed that personal importance of outbreak mitigation and beliefs surrounding others' cooperation are associated with both health-protective behavior and support for government regulations. Further, Swiss participants high in trait self-control engaged in health-protective behavior more often. Interestingly, perceived risk, age, and political orientation consistently displayed nonsignificant weak to zero associations with both health-protective behavior and support. Together, these findings highlight the contribution of self-control theories in explaining COVID-19-relevant outcomes, and underscore the importance of contextualizing self-control within the cooperative social context.

Climate policy support as a tool to control others' (but not own) environmental behavior?

Drastic reductions in greenhouse gas emissions are necessary to successfully mitigate climate change. Individual environmental behavior is central to this change. Given that environmental behavior necessitates 1) effortful individual self-control and 2) cooperation by others, public policy may constitute an attractive instrument for regulating one's own as well as others' environmental behavior. Framing climate change mitigation as a cooperative self-control problem, we explore the incremental predictive power of self-control and beliefs surrounding others' cooperation beyond established predictors of policy support in study 1 using machine-learning (N = 610). In study 2, we systematically test and confirm the effects of self-control and beliefs surrounding others' cooperation (N = 270). Both studies showed that personal importance of climate change mitigation and perceived insufficiency of others' environmental behavior predict policy support, while there was no strong evidence for a negative association between own-self control success and policy support. These results emerge beyond the effects of established predictors, such as environmental attitudes and beliefs, risk perception (study 1), and social norms (study 2). Results are discussed in terms of leveraging policy as a behavioral enactment constraint to control others' but not own environmental behavior.
