We want to empower young people (16–24) to respond to cyberbullying with practical, safe steps and to become peer multipliers who can improve online culture in their schools, youth groups and communities. Objectives : Cyberbullying literacy & action readiness: Participants can identify key forms of cyberbullying and role-play at least three safe response options (self-protection, peer support, reporting/help-seeking) using scenario-based tasks. Bystander confidence: Participants show a positive shift in self-efficacy about intervening safely as bystanders without escalating harm. Youth-led prevention outputs: Participants produce at least 8 short videos, 12 photo-story posts, and a jointly agreed “Bystander Toolkit” to support prevention and help-seeking. Peer education multiplication: Each national team co-creates and tests a 45–60 minute peer-to-peer micro-workshop outline ready to deliver at home after the exchange.
