Relationship dynamics, parenting style, economic situation, family structure, quality of interaction within a family and parental behaviour towards a child present both protective and risk factors in child's future development which significantly affect the child's behaviour. Disfunctional families live with domestic violence, mutual distrust, lack of comunication and emotional instability. When it comes to parental rules and expectations, children from disfunctional families are often denied the emotional support, security and consistency; they grow up without parental supervision, with unclear or undefined boundaries so the children do not develop mechanisms to cope with their emotions. Consequently, disfunctional patterns such as poor comunication, high conflict levels, emotional coldness or state of physical and emotional abuse can compromise child's social and emotional development and also affect their educational outcomes. For the purpose of this thesis, research was carried of cases dated from 01/01/2019 – 30/04/2024 with rulings of criminal sanctions at the Criminal Registry of the Municipal Court of Zadar and Zadar County Police Administration Office (N=52). The results of research indicate that the impact of the family on juvenile perpetrators of a criminal offence is more pronounced due to family structure and overly lenient or neglectful style of parenting and disfunctional behavioral patterns of family members. However, the fact should be noted that children are now entering into educational system at a younger age, which in turn contributes to a more prominent peer influence and environmental influence on child's development and behaviour.
