![]() However, evidence is mixed, as additional reviews have been less conclusive. One recent meta-analysis showed that being a child of a Holocaust survivor was modestly associated with increased posttraumatic stress disorder (PTSD) symptoms and another meta-analysis of studies across any population or trauma-type identified a significant association between parental PTSD symptoms and child PTSD symptoms. Researchers have evaluated intergenerational trauma through two main paths: (1) the path from parental trauma exposure to child psychopathology and (2) the path from parental trauma-related symptoms to child psychopathology. Many studies to date have focused on the descendants of Holocaust survivors, whereas smaller bodies of literature have included other populations and traumatic events, focusing primarily on the transmission of trauma-related symptoms from the first (G1) to the second (G2) generation. Epidemiological studies provide some evidence for intergenerational trauma. This results in subsequent generations experiencing the psychological effects of a traumatic event without exposure to it, such as increased risk of developing trauma- and stressor-related disorders. Intergenerational trauma is the process by which the psychological impact of a traumatic event is transmitted from one generation to the next.
