Intergenerational transmission of traumatization: Theoretical framework and implications for prevention

Area of Science:

• Psychology
• Developmental Psychology
• Psychiatry

Background:

• Intergenerational transmission of traumatization (ITT) links parental trauma to offspring emotional and behavioral issues.
• While fetal exposure is a factor, PTSD-influenced parent-child interactions are a significant contributor to ITT.
• Existing models often overlook the role of parent-child dynamics in ITT.

Purpose of the Study:

• To introduce the Perinatal Interactional Model of ITT.
• To highlight the role of PTSD-driven parent-child interactions in ITT.
• To emphasize the potential for early psychosocial interventions to disrupt ITT.

Main Methods:

• Conceptual model development.
• Literature review on ITT, PTSD, and parent-child interactions.
• Analysis of social learning and regulatory capacity in offspring.

Main Results:

• The Perinatal Interactional Model posits that PTSD negatively affects parent-child interactions.
• These suboptimal interactions undermine child regulatory capacity and increase distress.
• This pathway largely explains poor social-emotional outcomes in offspring of parents with PTSD.

Conclusions:

• Parent-child interactions are a critical, modifiable pathway in ITT.
• Early psychosocial interventions during pregnancy can disrupt the intergenerational cycle of trauma.
• Targeting interactional patterns offers a promising avenue for preventing adverse outcomes in at-risk children.
