PTSD risk factors

While it's impossible to predict who will develop PTSD in response to trauma, there are certain risk factors that increase your vulnerability. Many risk factors revolve around the nature of the traumatic event itself. Traumatic events are more likely to cause PTSD when they involve a severe threat to your life or personal safety: the more extreme and prolonged the threat, the greater the risk of developing PTSD in response. Intentional, human-inflicted harm—such as rape, assault, and torture— also tends to be more traumatic than “acts of God,” or more impersonal accidents and disasters. The extent to which the traumatic event was unexpected, uncontrollable, and inescapable also plays a role.

Other risk factors for PTSD include:

• Previous traumatic experiences, especially in early life.

• Family history of PTSD or depression.

• History of physical or sexual abuse.

• History of substance abuse.

• History of depression, anxiety, or another mental illness.
