Post traumatic symptoms were evaluated with the Impact of Events Scale (IES) before CISD and again six weeks later and were compared to those of controls and a group who had rece ived a brief psychoeducational intervention, who were evaluated within the same time frame. Compared with controls, significant effects for the CISD condition and a brief psychoeducational intervention were observed on the intrusions and total scales of t he IES. CISD is effective in the short - term in reducing post - traumatic stress symptomatology, notably intrusive memories, following a critical incident. However CISD is no more effective than a brief psychoeducational intervention. CISD does not increa se post traumatic stress symptomatology.enThis is an electronic version of an article published in Humphries, C. & Carr, A. : The short term effectiveness of critical incident stress debriefing.
