Central European Journal of Paediatrics, 16(1), 93-95.http://hdl.handle.net/10400.15/2841School bullying is responsible for a serious number of biopsychosocial effects for students directly involved (1) and represents one of the highly important variables that influence mental health at school age. In addition, bullying is also a complex behaviour that occurs within a social context that goes beyond the interaction between the bully and the victim. As many other participants are involved, it becomes more clear that we should study bullying as a social phenomenon (2), by analysing the potential roles that peers play when facing bullying behaviour.engbullyingbystander rolesempathymoral disengagementjournal articleDOI 10.5457/p2005-114.262
