Family relationships and parents’ behavior towards their children are factors that significantly influence the development of a child’s personality and their behavior modeling. Parenting styles are often seen as having an impact on their child’s social functioning. Having this in mind, this paper presents the results of research on key aspects of the influence that parenting styles have on the development of social competences and anti-social behavior in children. Standardized instruments (SSBS-2 and VS scale) were used in the research, and the sample included a total number of 705 students and 44 head-class teachers2. The research was conducted in primary schools on the territory of Kosovo and Metohija (Serbia). The results obtained indicated a correlation between parenting styles and students’ social competences and anti-social behavior, with a mother’s detached attitude standing out as a negative predictor of children’s social functioning.
