What is the influence of parents, siblings, school, friends and the media?

In addition to the parent-child relationship, we also investigate the relationships between siblings. For many people, these relationships last the longest in their lifetime and their impact on child development is considerable. Peers and classmates, particularly those who become friends, also exert a significant influence on the development of children and young people. Furthermore, we look at the influence of a child's social status among its classmates and the impact of social media, which form such an important part of the lives of contemporary young people.
