There is increasing interest in young people's participation in the design and delivery of health services. But young people's views are not consistently sought or acknowledged, and they are still often marginalised in healthcare encounters. Drawing on original research and a diverse range of practice examples, Brady explores the potential for inclusive and diverse approaches to young people's participation in health services from the perspectives of young people, health professionals and other practitioners. She presents a practical new framework, embedded in children's rights, that shows how young people's participation can be integrated into services in ways that are meaningful, effective and sustainable.
