Olweus's 1993 book, Bullying at School: What We Know and What We Can Do, has been translated into 20 languages. The success of the program led to a government-led initiative to implement the intervention (which would become known as the Olweus Bullying Prevention Program [OBPP]) throughout all Norwegian elementary and junior high schools.
The OBPP has been systematically evaluated in a number of large-scale studies in Norway that have included more than 30,000 students. The study found reductions in students' reports of being bullied and bullying others, as well as increases in students' expressions of empathy.
In addition to Norway and the U.S., the OBPP has been implemented in Iceland, Sweden, and Lithuania, and is being piloted in Mexico, Brazil, and Germany.
