What Constitutes Trauma
The person must have directly
experienced the event, witnessed it, or
learned about it indirectly; the event must
have been life-threatening, involved
serious injury, or threatened physical
integrity; and it must have triggered an
intense emotional response of fear, horror,
or helplessness.
