Static and dynamic predictors of forensic mental health decision-making.

Abstract

In Canada, individuals found not criminally responsible on account of mental disorder (NCR) fall under the supervision of a jurisdictional review board (RB) per the Criminal Code. Limited research has examined whether RB decisions balance the needs of public safety with social reintegration as intended by federal legislation. To fill this gap, the present study determined whether forensic decisional outcomes in one provincial RB system accounted for information relevant to violence risk. Study instruments included the Level of Service/Case Management Inventory (LS/CMI), Historical Clinical Risk Management-20 Version 3, and the Revised Violence Risk Appraisal Guide. A retrospective longitudinal design was employed to examine an NCR cohort (N = 109) that entered the RB system between 2005 and 2010 and their respective RB hearings (N = 327) until 2015. Results indicated that risk-relevant information was supplied to the RB by forensic professionals; however, key criminogenic risk and need factors as defined by the LS/CMI were absent in clinical reports. RB decisions were still strongly predicted by empirically supported risk factors linked to violent recidivism. Higher release likelihoods corresponded to a proportionally greater reliance on dynamic risk factors to enact dispositions. Forensic risk instruments are central aspects of correctional rehabilitation, and the results demonstrated their relevance to forensic tribunals. It is recommended that information from a forensic risk instrument be routinely delivered to RBs to support evidence-based decision-making.
