Following a research on 179 cases assessed in the last 8 years the author discusses the efficacy of an introductory familiar meeting in order to involve into treatment non requiring teen agers, which means nearly all the teen agers that come in contact with a psychotherapist. After describing nine kinds of non- cooperative teen agers and two cooperative ones, the guidelines and the taking charge techniques are dealt with, from the first contact to the first/second family meeting: safety of the meeting, emotional implications, authority of the therapist, psychological explanations, sharing of personal stories, rebuilding of membership.
Keywords: Forced charge, to oppose the parents’ delegation, safety area, to accompany the teen ager, to invent a new definition of the problem.
