Abstract
The coronavirus (COVID-19) pandemic has caused an international public health and economic crisis. Despite the COVID-19 vaccine rollout in many countries from late 2020, non-pharmaceutical interventions are still required to minimize the spread of the virus. However, notable variation in voluntary compliance with these interventions has been reported. This study investigated various individual differences associated with intentions to comply with COVID-19 restrictions during a sustained (112 day) lockdown in Melbourne (Australia) in late 2020. Participants (N = 363) completed an online survey where they responded to various socio-demographic, health and psychological questions. Participants also responded to a series of vignettes that assessed their intended behaviour in specific situations and their knowledge of the current COVID-19 restrictions. Overall, it was found that greater levels of organization predicted greater intentions to comply with the COVID-19 restrictions, while higher socio-economic status, sociability and anxiety predicted lower compliance intentions. Further, individuals previously diagnosed with COVID-19 reported lower intentions to comply with the COVID-19 restrictions. The strongest predictor of compliance intentions, however, was a greater knowledge of the current restrictions. These findings highlight that public health orders around COVID-19 restrictions should be presented in a clear and uncomplicated manner and should target specific groups to increase compliance.
