This randomized controlled trial evaluated the effectiveness of the Renkli Adımlar (Colorful Steps) game- and drama-based school intervention in promoting empathy and reducing bullying perpetration and victimization among primary school children. Third- and fourth-grade students were allocated to an intervention or control group. The intervention consisted of eight weekly 40-minute sessions including educational games, creative drama, role-playing, storytelling, puppet activities, and collaborative learning. Empathy, bullying perpetration, and victimization were assessed before and immediately after the intervention using standardized instruments.
