Statistical society of this research was comprised of boy students that study in Uremia high schools at first, second and third grades at 89-90 educational year (N=10286). Having utilized traumatic events screening inventory and SCL-90 R on 1000 people, 129 people were recognized as persons with trauma experience and score higher than 90 at SCL-90 R. Sixty people of them were selected randomly. Having conducting clinical interview, they were assigned randomly to three groups of cognitive processing holographic reprocessing and placebo.
