    The Rapid Risk Assessment for Sexual Offense Recidivism, abbreviated as the RRASOR (pronounced like the cutting tool), is an actuarial scale designed to assess different levels of sexual recidivism risk for convicted sexual offenders. The RRASOR’s predictive accuracy (as measured by the ROC) is regularly found to be equal to that of other. assessing the risk of all outcomes (sexual, violent, and any recidivism). The accuracy of structured professional judgment methods fell in between these two methods. Finally, the current thinking in the ield conirms the promise of third-generation risk assessment methods as research tells us more about the relationship between speciic dynamic File Size: KB.

Within the field of criminology and sexual offences, the most common definition of recidivism involves reconviction of the same crime, or same style of crime (e.g., sexual versus non-sexual, violent versus non-violent).
