Chronic victims of school bullying The aim of the study is an overview of knowledge about chronic victimization by school bullying, which affects approximately 5-15% of pupils. It focuses on its specific risks in the psychosocial (impaired self-esteem and relationships with others), health (especially anxiety disorders, depression, emotional dysregulation, PTSD and borderline symptoms) and academic domains (reduced school achievement and adaptability). It also addresses its biological and individual environmental predictors. Particularly at risk for chronic victimization are students who are both excessively anxious and aggressive. The phenomenon of the ,Healthy Context Paradox' refers to that school -based interventions will reduce overall victimization rates, but often do not eliminate chronic victimization, and the situation of persistent victims may in turn worsen. The study presents the existing knowledge of intervention tailored to individual situation of chronically bullied students.
