1. The survivor of the life-threatening event
2. The onlooker, there but not being subjected to the trauma
3. The person who heard about the horrible situation and then arrived to see it for himself/herself. He/she then imagines how it must have happened. (includes firemen, policemen, ambulance men, relatives etc.)
4. The person who has only heard about what happened, imagines what occurred. And many more.
For Single Event Traumas:
Two or Three sessions are required mostly
For Multiple Event Traumas:
such as: combat, sexual abuse; domestic violence; etc.
each traumatic event can be dealt with separately over separate sessions but, depending on the way the involuntary recall represents, can also be dealt with in one session.
