Abstrakt: This study examined the association between suicidal ideation and posttraumatic stress disorder (PTSD) symptom trajectories in a nationally representative sample of United States Reserve Component soldiers. PTSD symptoms related to a traumatic event during the most recent deployment were assessed in four annual waves in 2010-2013 among 682 Reserve Component soldiers. Latent Growth Mixture Modeling (LGMM) was used to examine the longitudinal trajectories of PTSD symptoms. The association between the PTSD trajectories and suicidal ideation at waves 2 to 4 was examined in logistic regression analyses. Four trajectories were identified: resilience (73.0%), recovery (11.7%), late onset (11.6%) and chronic (3.6%). Pairwise comparisons demonstrated significant differences between trajectories in risk of suicidal ideation. Among the chronic trajectory group, 50.9% reported suicidal ideation (25.8% late onset group; 11.3% recovery group; 4.0% resilience group). After controlling for baseline characteristics, the late onset and chronic trajectory groups were more likely to have suicidal ideation than the resilience and recovery trajectories, respectively. Findings suggest the late onset and chronic trajectories of PTSD symptoms are associated with higher risk of suicidal ideation. They support the importance of follow-up assessment of suicide risk even among individuals with low PTSD symptoms at homecoming.
