Adolescence is a period of great change in relationships with parents and peers. A traditional, simple view was that relationships with peers became more influential, and relationships with parents less so, through adolescence. This has some truth in it; the young person becomes increasingly independent from parents, spending more time in peer groups through the teenage years. However the picture is inevitably complex, varying in different cultural settings and historical periods. ‘Relationship changes—parents and peers’ looks at the change in relationship with parents, including emotional closeness, trust, disclosure, conflict, autonomy, and control. It then goes on to consider peer group relationships: friendships, popularity issues, peer influence, and bullying.
