Issues that tend to put people at higher risk for developing PTSD include increased duration of a traumatic event, higher number of traumatic events endured, higher severity of the trauma experienced, having an emotional condition prior to the event, or having little social support in the form of family or friends. In addition to those risk factors, children and adolescents, females, minority groups and people with learning disabilities or violence in the home seem to have a greater risk of developing PTSD after a traumatic event.
