Effects of childhood inter-parent conflict on reactive aggression in emerging adulthood: the role of parental warmth, and emotional dysregulation

While previous research suggests that interparental conflict (IPC) influences aggression, the mechanisms through which it occurs remain underexplored. This study examines the relationship between childhood exposure to IPC and reactive aggression in emerging adulthood, with a focus on the mediating roles of parental warmth and emotional dysregulation. Data were collected from 152 participants aged 18 to 29, using a combination of well-validated instruments to measure IPC, emotional dysregulation, reactive aggression, and perceived parental warmth from mothers and fathers. Results indicate maternal warmth emerged as a key mediator, especially for females, whereas emotional dysregulation played a stronger mediating role among Chinese participants. Paternal warmth and emotional dysregulation did not significantly mediate the relationship. These findings underscore the protective role of maternal emotional support in mitigating the adverse effects of IPC on aggression, with notable variations across gender and cultural contexts. The study highlights the importance of interventions targeting maternal warmth and emotional regulation, particularly in cultures where emotional suppression is prevalent, to reduce the long-term impact of IPC on aggressive behavior.
