Prevalence and associated factors of post-traumatic stress disorder in Lebanon: A literature review.

Lebanon has been under continuous conflict for more than four decades, putting millions of Lebanese at a high risk for post-traumatic stress disorder (PTSD) and creating a complex collective trauma. This paper aimed to review all studies from Lebanon reporting on PTSD in order to describe the prevalence of PTSD and its associated risk factors among Lebanese adults. A search of the MEDLINE/PubMed database was conducted in February/March 2021 to identify research articles on PTSD in Lebanese adults. A total of 1064 articles were identified, out of which 11 articles (5875 participants) published between 2003 and 2020 were included. PTSD prevalence estimates were highly variable across the individual studies, ranging from 2 % to 98 %. Female sex, economic hardship, lower educational level, being unemployed, number of witnessed/experienced traumatic events, and presence of comorbid psychological disorders were associated with higher PTSD rates. In light of the increasing PTSD risk in the Lebanese population as a result of the recent Beirut blast and ongoing social and economic crises, further culturally competent research is needed to provide rigorous evidence on the prevalence, course, and severity of PTSD in Lebanon.
