Currently, increasing numbers of psychotherapeutic concepts are being developed and evaluated for those adolescents who already in their adolescence fulfil the diagnostic criteria for a borderline personality disorder. The aim in this regard is to treat this group of patients adequately as early as possible. It has proven possible using the psychoanalytic-interactional method (PIM-A) and working in-house with adolescent patients with a borderline personality disorder or with structural disorders to demonstrate in an initial randomised controlled therapy study in an inpatient setting that this represents an effective treatment option (cf. Salzer, Cropp, Jaeger, Masuhr & Streeck-Fischer, 2013; Salzer, Cropp & Streeck-Fischer, 2014).
The intention is within the context of the feasibility study to adapt the inpatient treatment concept using the psychoanalytic-interactional method (PIM-A) to date for adolescents with a borderline personality disorder (cf. Streeck-Fischer, Cropp, Streeck and Salzer, 2016) to the outpatient setting and to implement it accordingly.
N=10 adolescents with a borderline personality disorder are to receive outpatient, manualised depth-psychology based long-term therapy under the German Regulation on the Conducting of Psychotherapy with up to 60 sessions over 12 months. N=10 adolescents with a borderline personality disorder are to be observed under treatment as usual over the period of 12 months and to subsequently receive therapy. Conduct a standardised diagnosis on the basis of DSM-5, as well as record the symptomatology in external and self-evaluation.
