Abstract
BACKGROUND/OBJECTIVES: This study examined the association between maternal anger, children's externalizing symptoms, and the moderating impact of maternal adverse childhood experiences (ACEs) in the context of intimate partner violence (IPV). The primary objective was to investigate whether maternal ACEs alter the link between maternal anger and children's externalizing symptoms, guided by theoretical frameworks such as the stress sensitization and stress steeling models. METHODS: A sample of 159 Portuguese mothers exposed to IPV participated in the study, completing a protocol of self-report measures. Measured variables included maternal anger, ACEs, children's externalizing symptoms, and IPV. RESULTS: Results indicate a significant moderation effect of ACEs on the association between maternal anger and externalizing symptoms at low levels of ACEs. Conversely, at moderate and high ACEs levels, no statistically significant association exists between maternal anger and children's externalizing symptoms. CONCLUSIONS: Clinical implications emphasize the importance of tailored parenting interventions to prevent externalizing symptoms in children, integrating diverse emotion regulation strategies while considering the impact of maternal ACEs.
