摘要：Research background and hypothesis. Research shows that significant numbers of children at school become victims of aggression which manifests as bullying or harassment (Zaborskis, Vareikienė, 2008). Bullying at school is associated with many long-term harmful physical, mental and social consequences for all involved in this process: for aggressors, victims and those who are forced to watch bullying (Širvinskienė et al., 2008). In Lithuania, the number of children who are bullied and children who bully is far greater than in other European countries: approximately a third of 11–15 year-old Lithuanian schoolchildren become frequent victims of bullying (Zaborskis et al., 2005). Bullying is defined as conscious threatening harassment or physical actions against a child who is unable to defend himself/herself repeatedly by one child or a group of children (Širvinskienė et al., 2008). This phenomenon involves a wide range of behaviours – from physical attacks to nicknaming and verbal abuse, from ignorance to frightening looks, from individual attacks to group actions or anonymous messages (Zaborskis, Vareikienė, 2008). Research aim was to determine the relationship between self-confidence and bullying among Kaunas City athletes and non-athletes adolescents. The object of the research was the relationship between self-confidence and bullying of adolescents. Research methods. The research was conducted from September, 2011 to December, 2011.
