The aim of this study was to examine the role of personal and family characteristics in emotional regulation of early adolescents. It was assumed that children's emotional regulation is determined by individual child's characteristics (dimensions of temperament and pubertal status) and family factors that include children's assessment of parental behavior of mothers and fathers (acceptance, rejection or control) and children's perceptions of conflict between parents (conflict properties, self-blame and perceived threat). The research included 562 children (280 girls and 282 boys) with an average age of 13 years. The results of this study show that significant predictors of emotional regulation of boys and girls are two dimensions of temperament - effortful-control and negative affectivity. Children who have a more pronounced effortful-control and are less prone to negative emotions better regulate their emotions. Family variables significantly contribute to the explanation of emotional regulation only in boys, where significant predictors of emotional regulation are maternal control and perception of father's rejection. Boys who perceive a higher degree of maternal control and father's rejection are less capable in regulating their emotions. PUBLICATION ABSTRACT
