The review defines school bullying as a form of aggression that involves a power imbalance, where the bully exercises influence over the victim, causing direct or indirect harm. It highlights the prevalence of bullying in various contexts, including schools, universities, and even online environments. The review also explores the factors contributing to bullying, such as family dynamics, communication issues, and social interactions. The review emphasizes the negative impacts of bullying on both victims and bullies, including psychological and physical health issues. It discusses the role of spectators, who can either support or enable the bullying behavior.

Finally, the review calls for more research and intervention programs to address bullying, particularly in educational settings. It suggests that understanding the complex relationships between the involved parties is crucial for effective prevention and intervention strategies.This theoretical review aims to compile aspects related to bullying, starting with an overview of the problem.
