The book conveys the fundamentals of a new integrative trauma therapy specifically developed for adults with childhood traumas. However, the method is also highly suitable for trauma therapy in general and can be applied to trauma synthesis and processing for Type I trauma as well. The application of IRRT for Type I traumas is theoretically justified in this book and illustrated with examples. It can be integrated into both behavioral therapy contexts and depth psychological settings. The method "Imagery Rescripting and Reprocessing" is based on imagination and cognitive restructuring, incorporating elements of in-sensu exposure and imaginative resource-oriented work with traumatized individuals. The book presents practical elements of therapy. The case studies demonstrate the working methods of the method's founder, Prof. Mervin Smucker. Work materials and templates are useful additions for the practical application of IRRT.
