A complex systems perspective on compliance with behavioral measures during the COVID-19 pandemic in the Netherlands: How psychological networks can inform interventions.
Health care agencies around the world recommended behavioral measures regarding hygiene and physical distancing to manage the COVID-19 pandemic. The current research sheds light on the interplay of psychological factors related to compliance and well-being during the pandemic. We do so by presenting a complex psychological network based on a large-scale survey (N = 6093). In total, participants were invited five times to complete this survey over a period of approximately 10 weeks (April 23th – June 30th 2020). The third and fifth wave included interventions aimed at influencing the psychological networks. We found that 1) compliance and well-being during the pandemic seemed connected through negative emotions and therefore were related factors and 2) trust in authorities influenced support for behavioral measures, which is in turn associated with compliance during the COVID-19 pandemic. Furthermore, the network structure was used to design multiple interventions, aimed at psychological variables varying in their relative importance for the network. The interventions significantly affected the variables the intervention was aimed at as well as other variables in the networks. The effects of interventions on variables related to the aim of the interventions were partially explained by the network structure. The results suggest that the network structure can be an important source of information for designing effective interventions aimed at influencing the public’s psychological systems in relation to pandemics.
