Adolescence is a period of change. An existential change that is a change in the sense of who one is, a change in one’s identity. It may be a catastrophic crisis in identity, so that there is an uncertainty about being a person at all. Adolescence is a process of learning a new identity without knowing clearly where one will get that new identity from. The authors reflect on these issues that nowadays increasingly involve schools, social stakeholders and mental health services when a treatment response is needed for problematic adolescents and their families. They provide examples of functioning of both the staff and adolescents group as they interact daily in a therapeutic community.
