Understanding the Intergenerational Cycle of Trauma and Violence: Maternal Adverse Childhood Experiences and Parent-to-Child Aggression Risk

Adverse childhood experiences (ACEs), such as exposure to maltreatment and household dysfunction, are major risk factors for physical and mental health problems across the lifespan. While the relationship between ACEs and health outcomes is well established, what effects ACEs might have on parent-to-child aggression are less known. The negative consequences of ACEs on parental aggression can be even more pronounced with multiple exposures to different patterns of ACEs. This study examined the association between patterns of maternal ACEs and subsequent parent-child aggression risk. A diverse sample of young women (N = 329; mean age = 26.3 years) was recruited at a large, urban university medical center. Participants completed self-report measures of the ACEs Questionnaire and the Adult-Adolescent Parenting Inventory-2. Latent class analysis was used to identify classes of women with similar patterns of exposure to ACEs and to examine the associations between ACEs classes and parent-to-child aggression risk. Three latent classes, characterized by distinct patterns of maternal ACEs, were identified: Low ACEs (63% of the sample), High Parental Separation/Divorce (20%), and High/Multiple ACEs classes (17%). Women in the High/Multiple ACEs class were more likely to report higher levels of parent-to-child aggression risk (i.e., inappropriate expectations, belief in corporal punishment, lack of empathy) than those in the other classes (Wald(2) = 8.63, p = .013). Preventive interventions targeting parental attitudes and behaviors among young women exposed to ACEs may decrease the risk for further perpetuation of aggression in the next generations.
