Incorporation of Change into Risk Assessments Using the Violence Risk Scale-Sexual Offense version

Mark Olver


This preconference workshop session will feature the use of the Violence Risk Scale-Sexual Offender version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003, 2017) to assess risk and evaluate change. The session will feature the interpretation of VRS-SO data within the context of risk assessment, treatment planning, and the assessment of change, including report writing and adjustments of risk appraisals based on updated normative data available for the tool. The session will serve as a useful refresher for those who currently use the VRS-SO or for those who may be interested in learning more about its use in risk assessment and range of applications, based on the available data.
