Intergenerational Trauma Transmission

How adverse childhood experiences pass from parent to child through parenting behaviors

The Transmission Mechanism

Intergenerational trauma transmission operates through a specific causal pathway: parents who experienced childhood adversities develop altered stress responses and coping mechanisms that manifest in their parenting behaviors. These negative parenting practices then create adverse childhood experiences for their own children, perpetuating the cycle. Understanding this mechanism is critical for intervention design—breaking the cycle requires targeting parenting behaviors, not just treating trauma symptoms.

Maternal History of Childhood Adversities and Later Negative Parenting

This systematic review synthesizes evidence establishing the causal pathway from maternal adverse childhood experiences (ACEs) to negative parenting practices. Mothers with histories of childhood maltreatment, neglect, or household dysfunction show significantly elevated rates of harsh discipline, emotional unavailability, and inconsistent parenting. The review identifies parenting behavior as the primary mediator of intergenerational trauma transmission—providing a clear intervention target for breaking cycles of family violence.
