The combination of analytic individual and group-psychotherapy is indicated for patients suffering from borderline-personality-disorder, due to their lack of experience of triangulation and their tendency to split objects into absolutely good or bad partial objects. If the patient develops a negative image of the one therapist, the other is represented as good enough to work through the negative relationship. The precondition for this practice is that both therapists exchange their conflicting feelings owing to their different countertransference, in order to integrate the splitted partial objects.
