Intergenerational trauma

Intergenerational trauma is the transmission of psychological distress and its effects across generations, through family relationships, social conditions, and sometimes biological pathways.

Attachment theory: A psychological framework explaining how early relationships with caregivers shape expectations, emotion regulation, and later relationships. Caregiving shaped by trauma can influence how safety and distress are handled in the next generation.
Holocaust survivor families: Families whose members include survivors of the Nazi genocide and its aftermath. Studies of these families helped establish clinical interest in trauma across generations.
Rachel Yehuda: A psychiatrist and neuroscientist known for research on trauma, PTSD, and Holocaust survivor families. Her studies have examined stress biology in survivors and their offspring.
Trauma-informed care: An approach to services that recognizes trauma's prevalence and seeks to avoid retraumatization while supporting safety and choice. It can guide services addressing family effects without reducing people to inherited trauma.
Nature versus nurture: A longstanding debate about the relative contributions of inherited biology and environmental experience to human traits. Intergenerational effects may involve both inherited biology and environments shared across generations.
Social learning theory: A theory that people learn behaviors and expectations by observing others and the consequences they experience. Children may acquire threat responses and coping patterns by observing traumatized family members.
Transgenerational trauma: A term for psychological and social effects of trauma that persist across generations. This closely related term appears in clinical and historical accounts of inherited effects.
Nicolas Abraham: A Hungarian-French psychoanalyst whose work explored how unspoken family histories affect later generations. His psychoanalytic ideas helped frame transmission through secrets and family narratives.
Family therapy: Psychotherapy that works with relationships and interaction patterns among family members. It can address communication and coping patterns maintained across generations.
Gene–environment interaction: The process by which genetic variation and environmental exposures jointly influence a trait or outcome. It offers a framework for studying why trauma exposure affects people differently.
