It has become increasingly recognized in recent years that emergency patients and those affected by accidents need not only medical care but also psychological support. However, staff in emergency services and fire departments are still uncertain about how to provide psychological first aid correctly. This is the central theme of the book, which illustrates the psychological situation of an accident patient and appropriate responses across nine chapters. The differences between the situations of directly and indirectly affected individuals are carefully presented, and the specific needs of certain patient groups, such as children, the elderly, foreigners, and the dying, are addressed. A dedicated chapter focuses on the stress situations faced by the helpers themselves. Following a concise and clear scientific section that discusses aspects such as behavior and knowledge, intuition and reason, or the practical relevance of psychological first aid, the authors provide helpers with a summary of established "golden rules" and a self-training program.
