Key Takeaways

From the Authors As published in the article
  1. Many demographic, clinical, and trauma-related factors have been linked to PTSD in youth, but whether these factors meaningfully improve prognosis beyond diagnostic status at initial clinical evaluation remains unclear.
  2. In a large prospective cohort of trauma-exposed youth, PTSD at the initial evaluation and at a 1-month follow-up strongly predicted later PTSD. Youth positive at both visits were most likely to have PTSD over 2 years of follow-up, while those without PTSD at both visits rarely developed it later. Other baseline factors added little prognostic value.
  3. For trauma-referred youth, reassessment of PTSD 1 month after the initial evaluation may help guide follow-up and treatment decisions. Youth negative at both assessments appear to be at low risk and may need only routine monitoring, whereas those with PTSD at either assessment, particularly both, may benefit from closer follow-up or trauma-focused treatment.
Extended Takeaways
  1. After the early posttrauma period, PTSD rates changed little: prevalence fell from 25.9% at baseline to 13.3% at 6 months, then remained between 9.6% and 13.0% through 24 months, suggesting that persistent symptoms by 6 months may mark a more chronic course.
  2. Among youth without PTSD at both baseline and 1 month, subsequent PTSD was uncommon at 2.6–4.2%, supporting a lower-intensity follow-up strategy when repeated early assessments are both negative.
  3. Comorbid anxiety/depressive disorders and current psychiatric care identified higher-risk youth even after accounting for initial PTSD, with OR =2.15, 95% CI, 1.55–2.99 and OR =1.72, 95% CI, 1.29–2.28, respectively; disruptive behavior/substance use was not a significant signal in this model.
  4. Intentional trauma remained a stronger longitudinal predictor than unintentional or witnessed intentional trauma, with OR =2.53, 95% CI, 1.77–3.61; trauma occurring 12 or more months before baseline also carried higher odds of later PTSD (OR =1.91, 95% CI, 1.05–3.46), so remote trauma does not imply low current risk.
  5. Perceived social support was protective only for ages 8–17 years (OR =0.58, 95% CI, 0.39–0.88) and not for ages 18–20 years (OR =0.80, 95% CI, 0.52–1.23), which may justify more active family, school, and peer support assessment in children and adolescents.
  6. Older age and female sex were associated with later PTSD independent of initial status, with OR =1.78, 95% CI, 1.31–2.41 for ages 13–17 years, OR =2.71, 95% CI, 1.65–4.46 for ages 18–20 years, and OR =1.78, 95% CI, 1.31–2.41 for female sex, while race and ethnicity were not significant.
