Bullying is one of our major public health problems today. Every stroke, slur or act of exclusion is a violation of children’s fundamental rights. All adults must act in the best interests of the child and ensure that every young person has their rights met. The development and dissemination of research-based knowledge about bullying is vital in the quest for a world where no child is subjected to bullying. The focus of the World Anti-Bullying Forum is that the best available knowledge about how bullying among children can be prevented is shared among practitioners, policymakers and researchers.
