AbstractChildren in armed conflict are frequently deprived of basic needs, psychologically supportive environments, educational and vocational opportunities, and other resources that promote positive psychosocial development and mental health. This article describes the mental health challenges faced by conflict-affected children and youth, the interventions designed to prevent or ameliorate the psychosocial impact of conflict-related experiences, and a case example of the challenges and opportunities related to addressing the mental health needs of Rohingya children and youth.
