This study evaluated associations between pre-deployment neurocognitive performance and post-deployment posttraumatic stress disorder PTSD symptoms in a sample of deployed active duty Army Soldiers. As pan of a larger longitudinal study. each participant compelled baseline measures of memory. executive attention, and response inhibition. and baseline and post-deployment self-report measures of PTSD symptom severity. Data were subjected to multiple regression analyses that examined associations between baseline neurocognitive performances and longitudinal PTSD symptom outcome. Results revealed that pre-trauma immediate recall of visual information was associated with post-deployment PTSD symptom severity. even after controlling for pre-deployment PTSD symptom levels. combat intensity, age. gender. and test-retest interval. There was also an interaction between pre-deployment PTSD symptom severity and pre-deployment immediate visual recall and verbal learning, indicating that neurocognitive performances were more strongly and negatively associated with residualized post-deployment PTSD symptoms. These findings highlight the potential role of pre-trauma neurocognitive functioning in moderating the effects of trauma exposure on PTSD symptoms.
