Reconsidering Risk Pathways PTSD Predictors After Major Trauma in New Zealand and beyond

Abstract

The study’s identification of younger age, Glasgow Coma Scale (GCS) < 15, and vehicle-related trauma as robust predictors of PTSD adds depth to the global understanding of trauma outcomes. The association with younger age is consistent with international literature indicating that adolescents and young adults may be particularly vulnerable due to less mature coping resources and heightened emotional reactivity [2]. Likewise, the strong link with vehicle-related trauma reinforces the evidence that sudden, life-threatening accidents constitute a distinct psychological burden compared with other mechanisms of injury. Perhaps most intriguing is the finding that reduced consciousness at presentation (GCS <15) increased PTSD risk, a result that challenges earlier theories suggesting traumatic brain injury may shield against traumatic memory encoding. Instead, the evidence supports emerging perspectives that comorbid mild-to-moderate TBI can worsen psychiatric sequelae, a topic that merits more extensive neuropsychological and neurobiological investigation.
