New developments in the mental health of refugee children and adolescents.

The increase in refugees globally since 2010 and the arrival of many into Europe since 2015, around 50% of whom are under 18 years, have been the stimulus to greater investigation and publications regarding their mental health. This clinical review summarises selected themes in the field as described in the published literature since 2016. The themes include refugee statistics, premigration and postmigration experiences, psychopathology focusing on parent-child relationships, unaccompanied refugee minors and associations between resettlement, acculturation and mental health. Some important reviews and studies are discussed that address service and treatment provision. While there has been a recent increase in research in this field, more is needed into the course of psychopathology, protective factors and the promotion of integration into resettlement countries, as well as models of service delivery and treatment effectiveness. © Author(s) (or their employer(s)) 2019.
