The study approaches delinquency prevention as the process of increasing the amount of social support measures applied by parents and other members of adolescent social network. The main research question of the meta-analysis is: how can optimization of social support enhance the process of delinquency prevention? The results of the research emphasize that reasonable number of today's families fail to provide children with support necessary for successful socialization, formation of behaviour models and value systems. Delinquent children tend to live in less cohesive, structurally unfavourable families, where the balance of support and control is disturbed. Their parents utilize more direct means of control (homework checking, direct intervention, punishments, scolding), while supportive relations are underutilized.
