PFA is the immediate support to a person who has experienced a traumatic event or crisis by promoting safety and connectedness immediately after an event. The Systematic Review of Psychological First Aid study found that it can reduce immediate distress and prevent longer-term conditions (Bisson & Lewis, 2009).  For example, the U.S. army’s Battlemind training, and mental health post-deployment briefing, reported fewer symptoms of post-traumatic stress and depression symptoms (Adler et al., 2009; Hallman & Pischke, 2012)*. A study found that as little as 1-hour intervention can have a measurable impact over time, especially when conducted in small groups (Thomas et al., 2019).
