This article presents a study on the phenomenon of bullying from the perspectives of victims, perpetrators, and bystanders among students from grades 6 to 11 at an educational institution in Sincelejo, Sucre, Colombia, in 2012. The study used a non-experimental, cross-sectional design with a quantitative approach and a probability sample, employing the adapted CIMEI questionnaire (Avilés, 2003). The results indicate that students exhibit aggressive, verbal, physical, and psychological behaviors, causing distress, social isolation, and affecting the self-image of their peers. The findings contribute to the continuous improvement of the educational institution by providing tools for handling and addressing bullying, positively impacting the well-being of all students. The study also highlights the need for interventions to prevent and mitigate the negative consequences of bullying.This article presents a study on the phenomenon of bullying from the perspectives of victims, perpetrators, and bystanders among students from grades 6 to 11 at an educational institution in Sincelejo, Sucre, Colombia, in 2012.
