The Social Cure Properties of Groups Across Cultures: Groups Provide More Support but Have Stronger Norms and Are Less Curative in Relationally Immobile Societies

We investigate whether the social cure properties of groups vary across cultures, testing hypotheses that the associations between multiple group memberships (MGM) and depressive symptoms will (a) be mediated by social support and uncomfortable normative pressures, and (b) vary systematically with sample-level relational mobility. Analyses of data from a survey (N = 5,174) conducted within k = 29 samples show that MGM is negatively associated with depressive symptoms, an association fully mediated by social support and uncomfortable normative pressures. In line with our theorizing, in samples with higher levels of relational mobility constraints, the association between MGM and depressive symptoms is weaker, the associations between MGM and social support and between MGM and normative pressures are stronger, and the association between social support and depressive symptoms weaker. The indirect link between MGM and depressive symptoms via social support is significant at both low and high levels of relational mobility constraints.
