Intergenerational transmission of war-related trauma assessed 40 years after exposure.

The offspring of war veterans showed increased psychological suffering as a function of their fathers' war exposure intensity, but not of their fathers' lifetime PTSD. These results could be used to suggest that mental health support for veterans' offspring should consider the war exposure intensity of their fathers, and not just psychopathology. This could spare offspring's suffering if this mental health support could be delivered early on, after veterans return from war.
