The role of the family is crucial for the development of juveniles, their behaviour and norm-following, and plays a key role in shaping their values and behaviour patterns. While a whole-family upbringing is important, several other factors are also determinants of rule-following behaviour, such as the level of family cohesion, the level of aggression that may be present in the family, and the degree of parental involvement. Parenting style also shapes children’s behaviour and influences the likelihood of offending, with loving, supportive and understanding families being more likely to promote appropriate and compliant behaviour. While positive parental involvement, support, and directive parenting are associated with lower offending rates, neglectful, strict, or overly permissive parenting styles can increase the risk of subsequent offending. Supporting families to provide a stable environment for their children is key, including encouraging positive behaviours or providing resources for families experiencing difficulties.
