The necessity to have a precise time and a limited place where the group processes could take place, is a fundamental requirement for the survival of the group. This is to say that a stable setting with clear limited space must to be respected and offered to the group and to the therapeuthic couple’s mind. The group allows some important dynamic movements for the adolescent, allowing the displacement of the infantile unsolved dependence conflicts in regard to their parents on the group of peers. This permits the working-through of the object-relationships in function with the relationships connected with actual experiences and unsolved conflicts with parental figures. The experience permits, thanks to the peers’ presence, the re-elaboration and a way towards a groupal and individual identity.
