Individual psychoanalytical psychodrama with adolescents who present with borderline personality issues shows the fundamental role of the technique of the double. This mode of intervention helps the patient accept the setting and is suitable for cases involving acting out, the dominance of experiencing over thinking, and multiple types of anxiety. Play shared with a co-therapist embodying the double eventually helps to define a safer psychic and corporal space.
