Abstract
Despite the extensive body of evidence documenting how pandemic-related stressors (e.g., disruptions in daily routine) impact individuals' mental health, research examining family mechanisms through which stressors impact parental stress remains insufficient. The present study aims to address this gap by exploring a moderated mediation model that predicts parental stress resulting from the accumulation of pandemic-related stressors. Specifically, we hypothesized a second-stage moderated mediation model in which family resilience beliefs moderated the second-stage indirect paths through family relationships and marital satisfaction, resulting in conditional indirect effects. Study data were collected from American parents (n = 1386). There was no evidence that family relationships and marital satisfaction mediated the association between stressor pile-up and parent stress. In addition, family resilience beliefs did not significantly impact how marital satisfaction or family relationships affect parental stress. However, marital satisfaction mediated the relationship between stressor pile-up and parental stress across all levels of family resilience beliefs. The findings of this study carry significant implications for post-pandemic family interventions, suggesting the incorporation of resilience belief training and stress management strategies to improve intrafamilial communication.
