The aim of this research was to analyze the role of children's perception of mother's and father's parental behavior and emotional competence in explaining child aggressive behavior. The research included 203 children (111 girls and 92 boys) with an average age of 12 years. Children reported mother's and father's parental behavior by filling Parental Acceptance-Rejection Questionnaire- Child Version (Rohner, 2005), children emotional competence was assessed by Emotional Competence Questionnaire (Takšić, 2002), and aggression by Aggression Scale for Children and Adolescents (Vulić-Prtorić i Bartolić, 2006). Results show that mother's and father's parental behavior were significantly correlated with child aggressive behavior, in a way that percieved parental warmth-affection minimize aggressive behavior while perceived parental aggression, neglect and undifferentiated rejection increase aggressive behavior. Regulation and control emotion, as a measure of emotional competence, was also significantly correlated with child aggression. Children with higher level of emotional competence will show less aggressive behavior. The results confirmed a significant contribution of parental behaviour variables in explaining the variance in child aggressiveness. Along with regulation and control emotion, these variables explain 25,3% variance of aggressive behavior. Father's aggressive behavior was only significant predictor for children aggressiveness.
