Post-traumatic stress disorder, depression, and anxiety in adult Syrian refugees: What do we know?

In total, 15 eligible studies provided cross-sectional data for 8176 adult Syrian refugees resettled in 10 countries, with significant variation in assessment and sampling methods. Combined, these studies indicate prevalence rates of 43.0% (range: 23.4-83.4%) for post-traumatic stress, 40.9% (range: 20-44.1%) for depression, and 26.6% (range: 19.30-31.8%) for anxiety morbidity in adult Syrian refugees. Larger and more rigorous surveys reported similar prevalence rates to studies with less rigorous designs, but vast heterogeneity in prevalence of morbidity persisted among all. Conclusions: Syrian refugees could be over 10 times more likely to develop post-traumatic stress and other disorders than the general population. Although there are limitations when comparing studies with different research methodologies, the results of this study suggest increased focus on adequate mental health support is necessary.
