A 2019 Cochrane Systematic Review found low-quality evidence suggesting potential benefit for some people, however, the studies performed had a high degree of uncertainty due to bias and the evidence is not strong enough to recommend multiple sessions of early psychological interventions for all people who are exposed to trauma. As of 2017 The American Psychological Association assessed psychological debriefing as No Research Support/Treatment is Potentially Harmful.
