The relationship between shyness and aggression: The multiple mediation of peer victimization and security and the moderation of parent-child attachment

Many people empirically believe that shyness, as a withdrawn personality trait, is not correlated or is negatively correlated with aggression, however, previous studies have found that shy individuals show higher levels of aggression. According to the social fitness model, shy children are more likely to be excluded from the outside world and to exist in an internal state of unease. From this perspective, the present study investigated the effects of shyness on aggression by considering peer victimization and security and by finding moderating factors (parent-child attachment) to improve this phenomenon. The sample consisted of 689 children. Questionnaires were utilized to investigate the mediating mechanism of shyness on aggression from the perspective of peer victimization and security in children and the possible moderating effect of parent-child attachment. The results showed that shyness not only directly predicts aggression but also can influence aggression through the multiple mediating effects of peer victimization and security. In addition, we found that mother-child attachment moderated the relationship between shyness and peer victimization and between shyness and security. Father-child attachment moderated the relationship between security and aggression and between shyness and aggression.
