DyRiAS-(dynamic system for the analysis of risk)-Workplace Violence assesses the behavior of individuals with regard to the risk they present of committing a serious act of workplace violence. The focus lies solely on individuals who maintain a direct or indirect connection to the company in question and who have drawn attention to themselves by threatening violence, stalking or communicating violent fantasies. It provides risk assessment in cases of threats, notorious trouble-making, stalking, and other threatening behavior at the workplace. Dyrias requires practitioners to answer 32 “yes” or “no” questions about the individual. The tool then outputs a score on a scale from one to five, from harmless to dangerous. According to the reference list of the provider, it is used in several cantons in Switzerland.
