Stressful life events or conditions lead to increasing emotional instability in children and adolescents. In particular, the situation of young refugees requires new concepts. The book summarizes current stress and trauma research and reports on the living conditions of unaccompanied minors. In addition to other therapeutic concepts, it presents the newly developed START procedure, which is used internationally for initial stabilization. This resilience-promoting and culturally integrative short intervention is sought after in clinics and practices, in youth services, and in school psychological services.
