Combat exposure severity as a moderator of genetic and environmental liability to post-traumatic stress disorder

4 Sept 2013

Abstract excerpt

BACKGROUND: Twin studies of veterans and adults suggest that approximately 30-46% of the variance in post-traumatic stress disorder (PTSD) is attributable to genetic factors. The remaining variance is attributable to the non-shared environment, which, by definition, includes combat exposure. This study used a gene by measured environment twin design to determine whether the effects of genetic and environmental...
