KiVa program is effective in reducing bullying

KiVa has been evaluated in a large randomized controlled trial including 117 intervention schools and 117 control schools. The program has been shown to reduce both self- and peer-reported bullying and victimization significantly1. It influences multiple form of victimization, including verbal, physical, and cyberbullying2. In addition, positive effects on school liking, academic motivation and achievement have been reported3. KiVa also reduces anxiety and depression and has a positive impact on students' perception of their peer climate4. A remarkable 98% of victims involved in discussions with the schools' KiVa teams felt that their situation improved5. Finally, Finnish data from more than 1000 schools that started the implementation of KiVa in fall 2009 showed that after the first year of implementation, both victimization and bullying had reduced significantly6. KiVa program won the European Crime Prevention Award in 2009.
