Version 1 of the HCR-20 made a great impact on the field when it was published in 1994. Version 2, published in 1997, has been officially translated into 16 languages (and counting) and is used throughout the world. According to recent reviews, it is among the most researched and most effective violence risk assessment tools available, having been the focus of evaluations in more than a dozen countries. Version 3 of the HCR-20 is now available. It retains the features that made Version 2 so popular and successful and incorporates cutting-edge developments in practice, including case formulation and scenario planning methods.
