Bullying in adolescents: role, type of violence and determinants

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Objective To determine the prevalence of bullying and its determinants among adolescents attending school.

Method An analytical cross-sectional study was conducted with a sample of adolescents, who were selected using a multistage probability sampling, from 20 public educational institutions in a Colombian city, in which a simple and multivariate binomial regression was carried out.

Results A total of 500 adolescents participated from which 50.4% were women and 53.2% in their middle adolescence. Verbal violence prevailed in 66.5%, followed by physical violence in 32.0% and social bullying in 30.6%. 69.5% of the adolescents have been witnesses, 35.8% victims, and 14.2% aggressors. 80.5% of the aggressors were victims of bullying. In the multivariate analysis, an association was found between being a victim and having disabilities (PR:2.4; CI: 1.6-3.7), verbal aggression in the home (PR: 1.7; CI: 1.2-2.3) and drug abuse (PR: 1.7; CI 1.1-2.8). Being an aggressor was also associated with being a victim (PR: 7.2; CI 3.6-14.3) and alcohol abuse (PR: 2.2; CI: 1.3-3.8).

Conclusion The frequency of bullying observed and the associated determinants demonstrate the persistence of this problem in adolescents and the need to develop a culture of appropriate and inclusive coexistence that goes beyond the school setting.
