trauma exposure associated_with Post-Traumatic Stress Disorder

highlight the association between parental alcohol status, trauma exposure, and PTSD

one genetic factor accounting for heritable influences on trauma exposure and PTSD

test for common genetic influences on PTSD and AD in women after accounting for possible heritable influences on trauma exposure.

trauma exposure and PTSD were attributable to the same source of genetic variance

A trivariate genetic Cholesky decomposition was fitted to assess the degree of overlap in genetic and environmental influences between trauma exposure, PTSD and AD.

genetic and environmental influence on the three phenotypes in the trivariate analysis

the high genetic correlation we found between trauma exposure and PTSD has also been documented previously

tested this reduced model against a model in which a single factor accounted for genetic influences on trauma exposure and PTSD and found no significant change
