Abstract

Physical injuries and psychological disorders following a road traffic accident (RTAs) are a serious public health problem. The objective of this work was to conduct a systematic review and update of studies on the prevalence and predictive variables of post-traumatic stress disorder (PTSD) after RTAs. A systematic search was performed in databases including Medline, PsycINFO, Scopus and Elsevier, of articles published between January 2015 and August 2019, following PRISMA guidelines. Initial search showed a total of 1062 articles, and 28 met inclusion criteria. The available literature is heterogeneous in regards to aims and methodology. Prevalence rates ranged from 2,39 % to 62%. The most robust predictors of PTSD include: Female gender, perceived threat to life, lack of social support, persistent physical problems and previous emotional problems. The importance of early detection to prevent psychological sequelae is highlighted.
