Peer violence is a serious social issue in today's society and it preoccupies attention of many experts. Researches dealing with this problem are trying to discover factors that contribute to peer violence but they are also trying to discover factors which can prevent it or at least decrease its prevalence. The aim of this paper is to explore the relationship between emotional intelligence and peer violence. For this purpose, on the sample of 158 Primary School students in Višnjevac, we applied Questionnaire about Peer Violence in School (UNŠD), Questionnaire about Peer Violence in School- form for teachers (UNDŠ-N), Emotional Intelligence Test (ATTEI) and Emotional Regulation and Control Questionnaire (ERIK). We predicted a negative relationship between emotional intelligence and peer violence. Also, we predicted for emotional intelligence to be better predictor of peer violence than some demographic variables. Both hypothesis were partially supported. We found the relationship between emotional intelligence measured by ATTEI and being a perpetrator of peer violence (which was measured with UNDŠ and UNDŠ- N) but we didn’t find the relationship between emotional intelligence measured by ATTEI and being a victim of peer violence. Moreover, we found a positive correlation between emotional intelligence measured by ERIK and being a perpetrator and a victim of peer violence (UNDŠ) but we didn’t found the relationship with results on UNDŠ-N. We found for emotional intelligence to be a best predictor for being a perpetrator and being a victim of peer violence. On the other hand, we found that demographic variable-gender, was a best predictor for results on UNDŠ form for teachers.
