Researchers at Columbia University and the New York Psychiatric Institute found that while traumatic experiences during combat were predictive of full-blown Post-Traumatic Stress Disorder less than 32% of these veterans actually developed the disorder. Even with the most severe exposures, 30% did not develop PTSD.
The data suggested that for PTSD to develop some combination of other factors needed to be present. These included:
- A mental disorder other than PTSD, predating the combat experience.
- Age - younger soldiers were more susceptible.
- A history of having been physically abused as children.
- Having physically harmed civilians or prisoners of war.
