Family stress model and parenting in infancy: Social support and parenting self-efficacy as resilience factors

According to the family stress model (FSM), economic stressors undermine optimal child development through negative impacts on parent psychological well-being and family relationships, which in turn disrupt positive parenting. However, few studies have examined the role of interparental conflict among these pathways and the resilience factors that buffer the FSM processes. Understanding risk and resilience is especially relevant for families in Flint, MI, for whom poverty resulting from structural racism and chronic disinvestment has coincided with public health crises. Using 199 families from low socioeconomic backgrounds in an ongoing parenting intervention in Flint, this study examined whether parent psychological distress and interparental conflict mediated the association between economic pressure at baseline (around birth) and cognitive stimulation at 9 months, and whether parenting self-efficacy and social support moderated the sequential mediation. Data were collected through parent interviews at both time points. We found that the negative association between economic pressure at baseline and cognitive stimulation at 9 months was sequentially mediated by parent psychological distress and interparental conflict. Furthermore, this negative sequential mediation was reduced and became nonsignificant when parents reported higher levels of parenting self-efficacy and social support. These findings suggest that improving interparental relationships in addition to parent mental health may promote positive parenting in at-risk two-parent families and that strength-based interventions are needed to reinforce parenting self-efficacy and facilitate parents' social networks and connections with the community to foster positive parenting. Programs should address these issues during infancy to build a strong foundation for long-term healthy development. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
