ABSTRACT
BACKGROUND: Social distancing and mass quarantines were implemented worldwide in response to the current COVID-19 pandemic. Prior research has shown that such measures bear negative consequences for population mental health and well-being. Conversely, a growing body of evidence suggests that feeling positively identified with a group is associated with physical and mental health benefits. AIMS: This study tested whether national identification could promote wellbeing and physical health during the COVID-19 pandemic. METHOD: We used survey data conducted among 67 countries (N = 46,450). RESULTS: Mixed-model analyses revealed that national identity was associated with wellbeing - despite adjustment on social belonging, COVID-19 perceived risk, exposure and ideology. This effect did not extend to physical health. CONCLUSIONS: These results suggest that the mere feeling of belonging to a national group may have mental health benefits. We discuss the implications of our findings within the social cure framework and their relevance for population mental health under COVID-19.
