The book addresses the relationship between trauma therapy and systemic therapy. It connects current and fundamental concepts of trauma therapy with axioms of systemic therapy. Systemic methods and techniques are varied and further developed for trauma therapy. The second part deals with systemic trauma therapy for children, adolescents, and their reference systems. Based on aspects of child development and trauma specificity, a systemic concept for therapeutic practice is developed. It presents trauma diagnostic tools, describes therapy strategies, and derives interventions for traumatized systems.
