Psychological debriefing

A single-session intervention, delivered soon after a traumatic event, in which people are encouraged to recount the event and express their emotional reactions. A Cochrane systematic review found no evidence that single-session individual debriefing prevents post-traumatic stress disorder, and some trials reported worse outcomes in the debriefed group. The finding is often cited as a caution against assuming that early emotional expression is protective for everyone.

    Level A Systematic review

    Supports the claim that single-session individual debriefing did not reduce distress or prevent PTSD, with one trial showing increased risk at one year. Trial quality was generally poor, and the review concerns one specific format.
