The Effectiveness of "Bullying Control" Training on Bullying of Female Students

Bullying is one of the most common forms of violence in schools during adolescence. The aim of this study was to determine the effectiveness of "bullying control" training on bullying of female students.

The method of the present study was quasi-experimental with pre-test, post-test and follow-up with control group. The statistical population of this study included 320 high school students of Saadat School (District 1 of education in Qazvin province) in the academic year 2020-2021. Among them, 34 students were purposefully selected by considering the bullying scale score and inclusion and exclusion criteria and 17 people were divided into 2 groups by simple random method of lottery. The research instruments included a demographic questionnaire and the “Illinois Bullying Scale”. The content validity of the instruments was measured by qualitative method and the reliability by internal consistency method by calculating Cronbachchr('39')s alpha coefficient. Data were collected after performing 8 sessions of 90 minutes of training for the intervention group. Data were analyzed in SPSS .24. 

The interactive effect of time and group on bullying (F=36.08, P=0.001, η2=0.530), victimization (F=15.93, P=0.001, η2=0.332) and fighting (F=19.05, P=0.001, η2=0.331) were significant at the level of 0.01.

Bullying control training is effective in reducing bullying, fighting and victimization of students. Therefore, it is recommended to apply the present education to other students in other schools and districts to reduce bullying and its consequences.
