The association between PTSD and suicide warrants further investigation in large population-based studies. This study recently published in the Journal of Affective Disorders investigated whether a PTSD diagnosis predicted death by suicide in a large, nationwide cohort of people living in Sweden. The findings showed that PTSD was associated with increased suicide rates, with individuals diagnosed with PTSD twice as likely to die by suicide than those without PTSD. The findings point to the need to determine the effectiveness of interventions for people with PTSD with respect to suicide-related outcomes.
