This report focuses on knowledge about preventing bullying perpetration, because of the link between perpetration and later offending. Bullying is a serious problem. The prevalence of bullying varies according to its definition, the sample, the time period enquired about, etc. According to the DFE (2018), 17% of young people aged 10-15 in England were bullied in a way that made them frightened or upset, in the previous 12 months. Most anti-bullying programmes include several intervention components that are implemented across the school system, targeting the individuals involved in bullying, the peer group, teachers, school staff, parents and the wider community. The most widely used programmes are the Olweus Bullying Prevention programme (OBPP) from Norway, KiVa from Finland, ViSC from Austria and NoTrap! from Italy (Gaffney et al., 2019b). In general, anti-bullying interventions reduce bullying. The observed effect size of 0.153 corresponds to an approximate 19% reduction in bullying.
