The authors give a report about their experiences of five years on group talk psychotherapy with adolescents. The indication to take part in this method which is integrated in a multidimensional therapeutic concept, consists in psychosocial disturbances with crises. Mainly adolescents of 14-18 years of age are taken care of in the groups. Meetings take place once a week and last about 90 minutes each. We have to deal with open groups, e.g. the duration of participation is different depending on the patient's problems. New member to the group are admitted continuously, in most cases after clinical preparation. A rapid integration of new patients is possible through members who have already been in the therapeutic process for a certain time. In this paper the importance of the behaviour of the therapeutist is discussed too. Here more activity is necessary than in groups of adults.
