| Abstract: | This study examined the predictive validity of the HCR–20 (Historical, Clinical, and Risk Management) violence risk assessment scheme and the Psychopathy Checklist: Screening Version (PCL:SV). Files of 193 civilly committed patients were coded. Patients were followed up in the community for an average of 626 days. Receiver operating characteristic analyses with the HCR–20 yielded strong associations with violence (areas under curve AUCs?=?.76–.80). Persons scoring above the HCR–20 median were 6 to 13 times more likely to be violent than those scoring below the median. PCL:SV AUCs were more variable (.68–.79). Regression analyses revealed that the HCR–20 added incremental validity to the PCL:SV and that only HCR–20 subscales predicted violence. Implications for risk assessment research, and the clinical assessment and management of violence, are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
