How effective are multiple session early psychological interventions for the prevention of post-traumatic stress disorder (PTSD)?
The methodological quality of many of the studies included was poor. Many studies did not provide full details of the method of allocation and some bias was considered possible from the descriptions in 7 studies. Many studies did not provide full details of the method of randomisation, and therefore concealment was unclear or inadequate in 8 studies.
The prevention of long term psychological distress following traumatic events is a major concern. Systematic reviews have suggested individual psychological debriefing is not an effective intervention for preventing PTSD. Recently, other forms of preventive intervention have been developed: counselling, cognitive behavioural therapy, memory structuring interventions, critical incident stress debriefing and collaborative care interventions.
