This has generated the need for a systematic analysis of the factorsassociated with this type of behavior. To contextualize bias-based aggression and develop future interventionstrategies for young people, it is crucial to appraise published studies. This meta-analytic review aims to identifythe most commonly used theories to explain bias-based aggression, significant authors, countries, and institutions in this thematic field, as well as how they interrelate.Furthermore, it explores the most analyzed lines of research by researchers and discusses implications forpreventive interventions to address bias-based aggression. This review focuses on English-language literature andutilizes a systematic search strategy in Scopus, yielding 51 publications. Descriptive statistical and bibliometricanalyses were conducted using VOSviewer software. The results indicate a leadership role held by US researchersand institutions. Theories of mind and Social Ecological theories are found to be the most frequently employedtheoretical frameworks by authors. Schools are identified as ideal environments for addressing bias-basedaggression, whether dealing with aggressors, victims, or bystanders.
