Network Re-Composition Under Constraint: Asymmetric Social Pathways Linking Functional Limitation to Mental Health

• In Event: Social Connections and Health

Abstract

While aging is often characterized by strategic social optimization, functional limitation imposes a structural re-composition of social life that challenges older adults’ agency. By utilizing three waves of NSHAP data and interventional mediation analysis with marginal structural models, this study adjudicates between competing pathways linking functional limitation to depressive symptoms and anxiety among older adults. We differentiate between the normative resilience of interpersonal network characteristics (size, contact frequency, kin composition, density) and the structural vulnerability of community engagement (religious involvement, volunteering, organizational participation). Our findings reveal an asymmetry in mediation: while interpersonal networks remain structurally intact, they fail to buffer the psychological toll of limitation. Instead, the deleterious effects of functional limitation are primarily transmitted through the erosion of community engagement, which serves as a critical conduit for social agency and identity. This evidence challenges the applicability of Socioemotional Selectivity Theory and the community engagement compensation model in late life, suggesting that these adaptive strategies are inadequate when confronted with people’s declining physical functioning. Overall, adjusting for time-varying confounding, functional limitation affects mental health primarily through direct pathways, with modest indirect effects through community engagement rather than personal networks. This pattern highlights an important distinction between the resilience of close social ties and the vulnerability of formal social participation in the context of functional decline. This study emphasizes the importance of maintaining formal social participation as a pillar of psychological resilience in late life.
