This study examined the relation between posttraumatic stress disorder (PTSD) severity and aggression (verbal, psychological, and physical aggression) in a longitudinal dataset. Participants were 175 males in PTSD residential treatment who were assessed at pre-treatment, post-treatment, and at 4-month follow-up. Post-treatment PTSD severity predicted aggression at post-treatment and 4-month follow-up, adjusting for age, pre-treatment PTSD severity, and pre-treatment aggression. When examining the relation between aggression and specific PTSD symptom clusters, post-treatment Reexperiencing, Avoidance/Numbing and Hyperarousal symptoms predicted aggression at posttreatment and 4-month follow-up. These results support the hypothesis that post-treatment PTSD severity may be an important marker of post-treatment aggression risk and may offer unique information important to clinicians and patients focused on the development and maintenance of adaptive, non-aggressive relationships after intensive PTSD treatment.
