Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators.

In the field of critical bullying studies, norms and normality have been used to explain bullying in a manner that challenges the mainstream conceptualising of bullying. This study concentrates in a more detailed way on how normality and not-normality are connected to bullying and how the students define not-normality as a reason for bullying. I…

Associations between social norms and bullying bystander behaviours have been studied extensively over the years, but the mechanisms by which subjective norms influence bystander behaviours remain unclear.

Participants were 340 third through eighth graders and 66…

This study investigates possible individual and class correlates of defending and passive bystanding behavior in bullying, in a sample of 1,825 Italian primary school (mean age = 10 years 1 month) and middle school (mean age = 13 years 2 months) students. The findings of a series of multilevel regression models show that both individual (e.g.,…
