Problems of self regulation, e.g. emotional dysfunction, represent a core symptom of adult patients with traumatic childhood experiences. The study intends to evaluate the efficiency of a 14-week group therapy for adult survivors of relational trauma in childhood. Main interventions are psychoeducation about the sequelae of childhood trauma, teaching of skills for affect regulation and techniques for activating resources. The hypothesis is that the group therapy significantly improves the participant's capacity in emotion management and self-soothing.
