Associations Between Insomnia, Post-Traumatic Stress Disorder, and Depression in Adolescents


  • A traumatic event that occurs in the adolescent years is associated with increased post-traumatic stress disorder (PTSD) symptoms, depressive symptoms, and insomnia symptoms over a 2-year period post-trauma.

Why this matters

  • Insomnia is highly associated with PTSD: people with insomnia are more likely to develop PTSD after a traumatic event, and insomnia is a common symptom of PTSD.

  • PTSD and depression are also highly correlated, and depression, insomnia, and PTSD can have a larger impact in the adolescent years.

  • The interaction between PTSD, insomnia, and depression over time is unknown in adolescents, and this information may improve treatment.
