abstract="Prior research has found substantial heterogeneity in the course of key post-deployment outcomes, such as PTSD. The current paper employs growth mixture modeling to identify differential trajectories of change in the course of post-combat aggression. A Brigade Combat Team completed surveys within 72h of return from an Iraq deployment, 4 months later, and at 12 months after return. Based on model fit indices, analyses yielded four latent aggression trajectories: &quot;low-stable&quot;, &quot;delayed&quot;, &quot;recovery&quot;, and &quot;chronic&quot;. In addition, most individuals aligned with a &quot;low-stable&quot; trajectory indicative of minimal aggression in the first year following return from a combat deployment. A conditional model showed that lower posttraumatic stress and lower combat exposure characterized individuals aligned with the &quot;low-stable&quot; aggression trajectory relative to individuals aligned with &quot;chronic&quot; and &quot;delayed&quot; aggression trajectories. Implications for targeted intervention and future research are discussed.<br><br>Published by Elsevier Ireland Ltd.<p /> <p>Language: en</p>",
