Child Advocacy Centres (CACs), also known as Child & Youth Advocacy Centres (CYACs), Children’s Houses, and Barnahus, are a child-focused trauma-informed approach to improving the multidisciplinary response to abuse and violence in the lives of children and youth. Contemporary and Innovative Practices in Child and Youth Advocacy Centre Models brings an international perspective to contemporary and innovative CAC practices around the world. It provides a range of perspectives offering valuable insights, suggestions, and advice to stimulate ideas for establishing, growing and modifying a CAC model and multi-agency collaboration in order to build capacity to respond to the incredibly diverse types of cases, children, youth and families that come through a CAC’s doors. As authors explore diverse sociolegal, demographic and cultural contexts within different service environments, they draw attention to successes but are also honest about challenges, barriers, and potential pitfalls.
