Bullying involvement and the transition to high school: A brief report

School transitions are common educational experiences for children and adolescents and many of them worry about being bullied during this type of major life-changing point. In a sample of 701 Canadians assessed yearly from grade 5 (age 10) to grade 12 (age 18), we examined heterogeneous patterns of bullying involvement while statistically accounting for the transition into high school. Gender differences were also examined. Results indicated that on average, bullying victimization declined over time with a significant drop noted between grade 8 and grade 9 (the transition into high school), with few differences between girls and boys. Bullying perpetration also declined for most students (no gender differences), with a notable drop found at the transition into high school. However, for a subset of adolescents, the transition into high school was accompanied by an increase in bullying perpetration. These varied experiences highlight the need to model heterogeneity when examining the impact of school transitions on bullying, a neglected focus of inquiry to date. Our results suggest that moving into high school is beneficial for most adolescents involved in bullying, but not for all.
