Social awareness of the consequences of interpersonal violence, particularly against children and young people, has grown enormously in recent years. Psychotraumatological research has made a significant contribution to this by clearly showing that unprocessed stressful life experiences in the form of chronic stress and affect dysregulation can cause a wide range of psychological and physical disorders. With a transdiagnostic approach and based on a new learning paradigm involving memory consolidation, this method offers psychotherapists an innovative and integrative conceptual framework and a cross-methodological treatment algorithm that takes these findings into account. The content of this second edition has been revised and new therapeutic methods have been included.
