Outline of Final Research Achievements

The Japan Victimization Scale (JVS) has been devised to measure the bully victimization among Japanese students . We have confirmed its reliability and validity . This process has enabled researchers to quantify bullying experiences among the youth in an objective and scientifically sound manner.
we examined, using JVS, occurrence of bully victimization in pupils (n=5518; 10-15 years of age) and explored risk factors and preventative factors for such experiences. 　41% of the primary school students, and 29% of the junior high school students reported to have undergone bully victimization in the past few months. The reported rate of victimization among children was found to be 5-fold higher than that reported by their parents.The odds of being victimized were increased in association with bullying others and time spent for the internet, the level of depression and anxiety, whereas more friends and better school climates were associated with a decrease in the odds.
