This article presents the problem of bullying from the perspectives of victims, perpetrators, and bystanders among students in grades 6 to 11 at an educational institution in Sincelejo, Colombia, in 2012. A cross-sectional descriptive study with a quantitative approach was used, employing a probability sample and the CIMEI questionnaire (Avilés, 2003), adapted from a study by the Ombudsman (2000) in Colombia. The study found that students exhibit aggressive, verbal, physical, and psychological behaviors that cause distress, social isolation, and affect self-image. The research contributes to the continuous improvement of the institution by providing tools for managing and addressing bullying, impacting the well-being of all students. The findings indicate that victims experience social exclusion, verbal abuse, and physical aggression, while perpetrators engage in isolation and verbal bullying. Bystanders often remain passive, not intervening or even participating in the aggression. The study highlights the prevalence of bullying, emphasizing the need for interventions to prevent its negative effects on students' psychological and social development. The results show that bullying is a significant issue in schools, affecting students regardless of socioeconomic status, cultural diversity, or educational level. The study underscores the importance of addressing bullying from a psychosocial perspective, considering individual, family, school, and peer factors that contribute to the phenomenon. The research concludes that bullying is a serious problem in schools, requiring comprehensive strategies to mitigate its impact on students' well-being.This article presents the problem of bullying from the perspectives of victims, perpetrators, and bystanders among students in grades 6 to 11 at an educational institution in Sincelejo, Colombia, in 2012.
