The Effectiveness and Implementation of Psychological First Aid as a Therapeutic Intervention After Trauma: An Integrative Review.

Psychological First Aid (PFA) is known to be an initial early intervention following traumatic exposure, yet little is known about its optimal implementation and effectiveness. This review aims to examine the evidence for the effectiveness of PFA interventions and how PFA interventions have been designed, implemented, and experienced. MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, PsychINFO, Embase, Web of Science, PILOTS, and China National Knowledge Infrastructure (in Chinese) databases were searched.
