摘要:Bullying is a stressful phenomenon with many effects on the mental and social health of a child. This study examined the association of bullying and stress in children and adolescents. The participants were 574 students from the 5th and 6th grades of the primary school and from the three grades of junior high school. The Olweus Bully Victim Questionnaire was used as a measurement of bullying and the Adolescent Stress Questionnaire (ASQ) and Stress in Children (SiC) were used as a measurement of stress in junior high school and primary school children respectively. 26.3% of children reported being victims of bullying, 7.8% reported engaging in bullying behaviour and 34.7% had been both victims of bullying and had engaged in bullying behavior. 31.2% had no role in the phenomenon. Verbal bullying was the most frequent form of bullying (22%) followed by hidden manipulation of social relationships to hurt or socially exclude the victim (19%). Bullying frequency was the most potent determinant of victims’ stress. Higher distress in bullies was associated with a higher frequency of bullying behavior and more stopping behaviors by adults especially if bullies reported less social support or had many adult-type responsibilities in their lives. Stress management programs to reduce bullying should be the central axis of intervention as stress not only constitutes a mediating factor in bullying but it is also associated with the phenomenon.
