Parental Adverse Childhood Experiences and Intergenerational Family Functioning

Adverse childhood experiences (ACEs), including abuse, neglect, and household dysfunction, are common exposures that may continue to influence relational functioning into adulthood. In the United States, 63.9% of adults report at least one ACE and 17.3% report four or more, underscoring the relevance of childhood adversity to contemporary family life (Swedo et al., 2023). Research suggests that parental ACE histories are associated with later difficulties in adult attachment, emotion regulation, couple functioning, parenting, and some child mental health outcomes, although these associations are generally modest and vary across domains (Racine et al., 2025; Sirparanta et al., 2025). Examining these interconnected relational pathways may help clarify how childhood adversity influences family functioning across generations without assuming that such patterns are inevitable.

Scope and Prevalence of Parental Adverse Childhood Experiences

ACEs are common across populations, making their potential influence on later family functioning relevant beyond narrowly defined clinical groups. Internationally, a meta-analysis of 206 studies involving more than half a million adults found that approximately 60% reported at least one ACE, demonstrating that childhood adversity is not limited to a single national or cultural context (Madigan et al., 2023). These prevalence estimates are important because many adults with ACE histories later occupy roles as romantic partners and parents, creating multiple possible pathways through which earlier adversity may intersect with contemporary family relationships.

Effects on Family Relationships and Functioning

One pathway through which ACEs may influence family life is their association with adult attachment and emotion regulation. Adults reporting greater childhood adversity may experience more difficulty regulating emotion and greater attachment insecurity, although these relationships vary across attachment patterns and cannot establish causality (Snyder et al., 2024). These vulnerabilities may extend into romantic relationships. A meta-analysis found a modest association between childhood emotional maltreatment and poorer romantic relationship well-being, while dyadic research suggests that one partner’s maltreatment history is also associated with slightly lower relationship satisfaction and greater psychological distress in the other partner (Cao et al., 2022; Vaillancourt-Morel et al., 2024). Importantly, these effects were generally small, indicating that childhood adversity is one of many influences on adult couple functioning rather than a deterministic predictor of relational difficulty.

Couple distress and difficulties with emotional regulation may also intersect with coparenting, parental emotional availability, and the broader family climate experienced by children. Reviews of parental ACE research have linked caregivers’ childhood adversity with lower emotional availability, more problematic discipline practices, and greater risk for child internalizing and externalizing symptoms, with parental depression, anxiety, and dissociation identified as possible mediating processes (Cooke et al., 2021; Rowell & Neal-Barnett, 2022). At the same time, intergenerational effects appear neither uniform nor inevitable. Racine et al. (2025) found small associations between parental ACEs and child mental health problems but no significant association with several developmental outcomes. Similarly, Sirparanta et al. (2025) reported only a weak association between parental childhood maltreatment and offspring attachment insecurity and no significant association with attachment disorganization. Together, these findings suggest that parental adversity may shape family functioning through multiple relational pathways while leaving substantial room for resilience, protective relationships, and contextual influences.

ACE exposure and its family effects also occur within cultural and socioeconomic contexts. International research indicates that childhood adversity occurs across national settings, although prevalence varies across populations (Madigan et al., 2023). Within the United States, higher cumulative ACE exposure has been reported among some racial and ethnic minority groups and adults facing educational or employment disadvantage, patterns that may reflect broader structural stressors rather than family characteristics alone (Swedo et al., 2023). Families with ACE histories may also experience limited social support and socioeconomic strain, factors that can further influence family functioning and access to care (Lyu et al., 2023).

Proposed Solutions

Because parental ACEs may affect several levels of family functioning, interventions may be most useful when they address both individual and relational processes. Trauma-informed care may help parents examine how earlier experiences relate to present emotion regulation, attachment expectations, and stress responses, processes associated with ACE exposure (Snyder et al., 2024). Parenting-focused interventions also show measurable benefit. In a meta-analysis of 12 studies involving 709 families, group interventions for parents with ACE histories produced small but significant improvements in parenting outcomes and parental mental health (Lyu et al., 2023). These findings support approaches that strengthen emotional awareness, regulation, and responsive parenting.

Couple and family-level approaches may address relational pathways that parenting interventions alone do not target. Childhood maltreatment has been associated with modest reductions in romantic relationship well-being and small partner effects on relationship satisfaction and psychological distress (Cao et al., 2022; Vaillancourt-Morel et al., 2024). Interventions that strengthen emotional responsiveness, communication, conflict regulation, and mutual understanding may therefore be relevant for some couples with significant adversity histories. Family-oriented treatment may also help caregivers examine how partner dynamics affect coparenting and the emotional climate experienced by children.

Prevention efforts may also reduce risk before difficulties become entrenched within the family system. Because parental ACE exposure is associated with child health, behavioral, and relational outcomes, early identification in primary care, prenatal care, and family services may help connect caregivers with appropriate mental health and parenting supports (Arnold et al., 2023). Broader supports are also relevant because socioeconomic strain, limited social support, and barriers to treatment can shape family functioning and access to care (Lyu et al., 2023). Effective prevention may therefore require both clinical services and practical supports that reduce current stressors and strengthen family resilience.

Conclusion

Parental adverse childhood experiences are relevant to family psychology because their effects may extend beyond individual well-being into couple relationships, parenting, and child adjustment. Current evidence suggests that these associations are generally modest and vary across outcomes, indicating increased risk rather than inevitable intergenerational transmission (Racine et al., 2025; Sirparanta et al., 2025). Interventions that strengthen emotional regulation, parenting capacity, couple functioning, and access to supportive resources may help families reduce relational stress and reinforce protective processes. Addressing both past adversity and present family context therefore offers a broader framework for supporting healthier functioning across generations.
