A systematic review of socio-ecological factors contributing to risk and protection of the mental health of refugee children and adolescents

In the past decade, millions of children and adolescents have been forced to flee from protracted or newly erupted violent conflicts. Forcibly displaced children are particularly vulnerable for developing mental health problems. However, a timely and systematic review of the current evidence is lacking. We conducted a systematic review of factors contributing to the mental health of refugee children across different socio-ecological levels (individual, family, community, sociocultural). We systematically searched the databases Medline, PsycINFO, Web of Science, and Cochrane for English studies published in peer-reviewed journals between August 2010 and May 2020. Of the 2413 identified studies, 63 were included in the analyses. Only 24 studies were considered to be of high quality. Pre-migration individual (risk: exposure to war-related trauma, female gender) and post-migration family factors (risk: parental mental health problems and impaired parenting, protective: family cohesion) currently have the best evidence base. Post-migration community (protective: school connectedness, support by peers) and sociocultural factors (risk: discrimination and acculturative stress, protective: integrative acculturation) have gained some support in high-income settings. Prevention and intervention approaches should integrate factors across different socio-ecological levels. More longitudinal studies and research in low- and middle-income countries are needed to advance our knowledge on causal mechanisms behind factors contributing to refugee youth's mental health.
