Objective:The most common crisis intervention used with German rescue workers is Critical Incident Stress Management (CISM).
RESULTS regarding its effectiveness are inconsistent. A negative reinforcement of avoidance, due to premature termination of strong emotions during the Critical Incident Stress Debriefing (CISD), may explain this. The effectiveness of the CISD after terror attacks in Germany has not yet been investigated.
METHODS: All emergency responders deployed at the terror attack on Breitscheidplatz in Berlin were invited to take part in the study; 37 of the N = 55 participants had voluntarily participated in CISD; 18 had not.
RESULTS: Participants with CISD showed lower quality of life in psychological health and higher depressive symptomatology. Of these, females had lower quality of life in social relationships, whereas males showed more posttraumatic stress symptoms. Emergency responders from non-governmental organizations had higher phobic anxiety. Emergency medical technicians showed more somatic and depressive symptoms.
CONCLUSION: There is no conclusive explanation for why rescue workers with CISD score worse on certain measures. It is possible that CISD has a harmful influence due to negative reinforcement, or that there was a selection effect. Further research differentiating occupational group, sex, and type of event is necessary.
