The schoolbullying is a neologism which designates " a long-term violence, physical or psychological, perpetrated by one or more attackers (bully) against a victim (bullied) in a relationship of domination "(C. Blaya). This term is primarily used to describe repeated harassment behavior in schools. This phenomenon concerns one child out of seven in schools. Difficult to detect, it can have more or less serious psychological impacts (medium or long-term effects), such as dropout or anxious school refusal, loss of self esteem, major depressive disorder, suicide, eating disorders and leakage to substance abuse or alcohol. Its therapeutic follow-up is multidisciplinary and difficult. The aim of this paper is to draw the attention of health professionals to these new phenomena of violence in order to detect them as early as possible and thus provide optimal care.
