[The borderline personality (development) disorder during adolescence. Psychological assessment, treatment prerequisites, framework design, treatment phases].

Following a critical discussion on the term Borderline Personality Disorder during adolescence, assessment criteria are compiled that illustrate this disorder. In an overview of the psychodynamic literature it is clearly stated that already in the 1960s Borderline Disorders were described in childhood and adolescence without any development of valid criteria for these since then. Except for numerous case studies of these Borderline Disorders, there has been no research undertaken within psychodynamic psychotherapy on this disorder during childhood and adolescence to date. Specific disorder-related therapy approaches, whose effectiveness have been confirmed in therapy studies on Borderline Disorders in adults, have so far not been adapted to treating children and adolescents that have Borderline Disorders. These are portrayed as well as the treatment prerequisites and framework conditions that allow for a disorder-specific development oriented interactional psychotherapy of adolescents with Borderline Disorders. The interactional psychotherapy in its adolescence-adapted form is only gone into on the side. In conclusion there is an overview given of the various phases of the treatment.
