AbstractThe trauma response to extreme life events and/or the posttraumatic stress disorder (PTSD) were originally conceptualized as normal responses to overwhelming situations. In the last years there is increasing acceptance of the idea that exposure to a traumatic situation/stimulus may not be enough to explain the development of PTSD and the individual vulnerability factors plays an important role in understanding this condition.The study examines different approaches on psychological trauma (especially PTSD) in the literature in order to find more effective directions in trauma treatment.
