Do married and/or cohabiting individuals fare better during the COVID-19 pandemic? Satisfaction with life and depression among adult twins in the United States.

Due to social distancing measures implemented to mitigate the COVID-19 pandemic, individuals are spending more time isolated at home with limited physical social interactions. The current study investigated whether marriage and/or cohabitation is associated with satisfaction with life and depression among 732 adult same-sex twin pairs (monozygotic and dizygotic) in the US using online survey data. Twin analysis showed that married and/or cohabiting individuals were more satisfied with life and less depressed than those not married and/or cohabiting. The association between marriage and/or cohabiting and satisfaction with life was not confounded by between-family factors, whereas that between depression was mediated by familial factors. These findings suggest that being in a close relationship may mitigate some of the adverse consequences of the COVID-19 pandemic. Close relationships may be an essential source of support as individuals rely on their intimate partners when faced with the uncertainty and stress of the pandemic.
