Everyone who experiences a traumatic event may not develop PTSD. However, there may be additional factors that increase the risk for PTSD following traumatic exposure.  Previous studies have identified a number of factors that increase risk for PTSD across the genders, including:

  • Pre-existing mental health problems (e.g., depression or anxiety disorder)
  • Severity of the event
  • Type of event
  • Extent to which the event involved injury
  • Less functional coping styles and low stress tolerance
  • Prior trauma exposure
  • Dissociation during the event
  • Additional life stressors
  • Quality of available social support
