Objective: The current study examined prevalence of physical fighting and involvement in bullying behaviour among early adolescents and its association with depression. We were looking for possible gender differences as well. Methods: A cross-sectional, questionnaire study was performed on 800 adolescents between ages 11 and 14 in the area of Split, Solin and Kaštela. Physical fighting and involvement in bullying behaviour were assessed using questions from thr World Health Organization survey Health Behaviour in School-aged Children. Depression was measured using Children Depression Inventory. Results: Twenty four point two percent adolescent reported involvement in physical fighting and five point five percent reports involvement in bullyinh behaviour. Chi-square test indicates more male than female physical fighting and involvement in bullying behaviour. Adolescents who are frequently involved in physical fighting and bullying behaviour manifest higher levels of depressive simptoms than students who were never involved in physical fighting and bullying behaviour. Conclusion: Bullying is common among children, and in many cases lasts for years. We now recognized that physical fighting and involvement in bullying behaviour are at risk of developing depressive disorders. These findings may have potentially important clinical and preventive implications.
