This study examined the effectiveness of Critical Incident Stress Debriefings (CISD). The purpose of this study was to determine if people who received CISD reported fewer symptoms of psychological distress when compared to people who did not participate in CISD. After screening 92 articles, a meta-analysis was conducted on five studies that were selected because they used the Mitchell model, employed outcome measures, and had a comparison or control group. As hypothesized, participants who were debriefed had a significant positive effect size. A second hypothesis, comparing Emergency Services professionals to primary victims could not be tested due to the lack of relevant studies.
