Book excerpt: For centuries, residential child and youth care systems worldwide have provided homes for vulnerable children and adolescents. The implementation of children's rights, especially the right of participation, is assessed as an important base for promoting the best interests of the child in an out-of-home care environment. Featuring contributions from distinguished international authors, this volume offers an in-depth understanding of crucial participation processes and underlying power structures when involving young people in decision-making about their care and everyday life in different out-of-home care institutions. Contributions cover a broad spectrum of current research findings concerning the participation of young people in foster families and residential living groups in Australia, Canada, Germany, Ireland, Italy, Portugal, Norway, Sweden, and Switzerland as well as cross-nationals perspective on children and young people’s participation in foster and residential care placements in Great Britain and France. The volume fills major gaps concerning the participation of young people in different out-of-home care and policy settings and will be required reading for policymakers, researchers, practitioners, scholars, and students interested in increasing opportunities for young people’s participation and creating better out-of-home care settings for vulnerable young people.
