Giving psychological therapy to everyone involved in a traumatic event could be a waste of time. Researchers from the University Hospital of Wales in Cardiff carried out a review of 11 studies with a total of 941 participants for the prestigious Cochrane database. The study looked at the effectiveness of several sessions of therapy given to all people exposed to a traumatic event, regardless of their symptoms. The study found that the interventions had had no effect and, in some cases, had actually made things worse. The researchers pointed out that psychological therapies could still be effective for people with actual PTSD symptoms; something they intend to research next.
