Aim 1: To examine the effects of the training program on PTSD and neurocognitive symptoms in Veterans. PTSD symptoms will be measured using the Clinician Administered PTSD Scale (CAPS) interview and neurocognitive functioning will be assessed with Delis Kaplan Executive Functioning System subtests. Individuals completing COGENT are hypothesized to show a) greater reduction in PTSD re-experiencing symptoms and b) improved neurocognitive performance relative to those in ST over time. Exploratory aims will also examine changes in PTSD diagnostic status across groups.
