KiVa is effective

Undenied scientific evidence of KiVa effectiveness


KiVa is developed by experts who have been studying the phenomenon of bullying and its mechanisms for decades. The team is led by PhD, Professor Christina Salmivalli and PhD, Special Researcher Elisa Poskiparta, both of University of Turku.

No other antibullying program has been studied as rigorously as KiVa, before and after the nationwide implementation. The program has been shown to reduce both self- and peer-reported bullying and victimization significantly.

Data from more than 1000 Finnish schools showed that after the first year of implementation, the program reduced all forms of bullying significantly. 98 % of the bullied students felt that their situation improved after the intervention. In addition, positive effects on school liking, academic motivation and achievement have been reported. KiVa also reduces anxiety and depression and has a positive impact on students’ perception of their peer climate.

Numerous studies show that KiVa is effective outside of Finland as well. The Netherlands, Estonia, Italy and Wales are among the regions, where research has been conducted about KiVa, adding to the positive findings about the program.

Reduction in both bullying and being bullied has been reported already after the first year of implementation. The graphic illustrates the reduction rates after 1st, 2nd, 3rd etc. year of implementation in all Finnish schools using the program.
