Prevalence and factors associated with bullying: differences between the roles of bullies and victims of bullying.

Abstract

To identify the differences between the prevalence and factors associated with involvement in bullying among schoolchildren from Recife, in the role of victim and perpetrator.This is an epidemiological, cross-sectional, analytical study, with a probabilistic cluster sample of 1402 students enrolled in high schools in Recife. Data analysis consisted of a descriptive analysis, followed by the application of Pearson's chi-squared test with statistical significance of 0.05 and 95% confidence interval. For the association analysis, multilevel modeling was used to control the cluster effect.It was observed that adolescents who feel different from other peers were associated with bullying, regardless of the role played. Being a victim was associated with being female, having low self-esteem, and using tranquilizers; being a transgressor was a protective factor. As for the role of perpetrator, being male, excessive alcohol consumption, having poor school performance, being a transgressor, and accepting peer violence were the associated variables; in turn, not defending their ideas when among friends showed to be a protective factor for bullying.The differences between the adolescents, whether in the role of victim or perpetrator, indicate that the advocacy and prevention actions should focus on these aspects, mainly in the school environment.
