School shootings - colloquially referred to as school rampages - represent a rare but serious form of targeted violence in schools. This book first presents the causes discussed in current scientific research. In addition to perpetrator characteristics, emphasis is placed on the private and school environment, the influence of mass media, accessibility to weapons, and the consumption of violent media. Secondly, primary and secondary preventive measures are presented, such as profiling, threat assessments and the phenomenon of leaking. And thirdly, the focus is on aftercare in school shootings, the aim of which is to cope with experienced psychotraumatic stress. Emergency psychological acute aids, short-term to medium-term, trauma-focused, as well as longer-term intervention measures for children, adolescents and adults are explained in more detail. Practical excursions on prevention as well as aftercare complement the corresponding chapters.
