The aim of this research was to study relational violence between peers from a psychosocial perspective, by analyzing family variables (family functioning and communication), social variables (social reputation –both perceived and ideal– and attitude towards institutional authority), and individual variables (psychological distress and suicide ideation) in adolescent students. The sample consisted of 8,115 adolescents aged 11 to 16 years from the State of Nuevo León, Mexico. We performed a forward stepwise multiple regression analysis, the results of which showed that the most important factor in the prediction of violent relational behavior at school is the nonconformist self-perception, followed by psychological distress. Finally, these results and their implications are discussed.
