<![CDATA[Aggressive behavior among adolescents is a global psychosocial problem that continues to increase and poses serious implications for mental health, educational outcomes, and social stability. Previous studies have demonstrated that adolescent aggression is influenced by a complex interaction between internal and external factors; however, empirical findings remain fragmented and have not been systematically integrated. This study aims to identify the most salient internal factors and to analyze external factors that function as predictors of aggressive behavior in adolescents. This study employed a Systematic Literature Review (SLR) approach guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. Literature searches were conducted in November 2025 across four major databases—Scopus, PubMed, ScienceDirect, and Google Scholar—covering articles published between 2015 and 2025. Of the 2,637 articles initially identified, 27 empirical studies met the inclusion criteria and were included in the final analysis. The findings indicate that adolescent aggression is significantly associated with internal factors such as low self-control, poor emotion regulation, and low self-esteem, as well as external factors including maladaptive parenting practices, exposure to violence, peer influence, and digital media addiction. These results highlight the importance of integrative and context-sensitive intervention approaches in addressing aggressive behavior among adolescents.]]>
