The role of genes and environment on trauma exposure and posttraumatic stress disorder symptoms: a review of twin studies.

Clinical psychology review - 1 Feb 2010

Afifi Tracie O, Asmundson Gordon J G, Taylor Steven, Jang Kerry L

Abstract excerpt

Behavioral-genetic (twin) methods are important tools for understanding the etiology of trauma exposure and posttraumatic stress disorder (PTSD). The purpose of the present article is to synthesize the results obtained from twin studies and outline important avenues for further investigation. Twin research to date suggests that: (1) exposure to assaultive trauma is moderately heritable whereas exposure to...
