Experiences of violence, sexual abuse, accidents, disasters or deaths of close relatives or friends, and other extreme situations can lead to trauma-related disorders. Since 2018, the World Health Organization has distinguished four such disorders in its classification list: "classic" and complex post-traumatic stress disorder, as well as prolonged grief disorder and adjustment disorder. These long-term effects are described in detail in the book. In recent years, a variety of interventions have been developed to effectively treat these disorders. This book is a translation of the original German 5th edition Traumafolgestörungen by Andreas Maercker, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. This new edition was largely redesigned due to the groundbreaking innovations in which the editor played a decisive role at international level. The new features include the chapters on: · Complex post-traumatic stress disorder · Childhood violence and its consequences · Low threshold and innovative interventions · Methods of cognitive behavioral therapy · Psychodynamic approaches The handbook on psychological trauma-related disorders. .
