Improving Risk Assessments for Sex Offenders: A Comparison of Three Actuarial Scales

  title={Improving Risk Assessments for Sex Offenders: A Comparison of Three Actuarial Scales},
  author={R. Karl Hanson and David Thornton},
  journal={Law and Human Behavior},
The study compared the predictive accuracy of three sex offender risk-assessment measures: the RRASOR (Hanson, 1997), Thornton's SACJ-Min (Grubin, 1998), and a new scale, Static-99, created by combining the items from the RRASOR and SACJ-Min. Predictive accuracy was tested using four diverse datasets drawn from Canada and the United Kingdom (total n = 1301). The RRASOR and the SACJ-Min showed roughly equivalent predictive accuracy, and the combination of the two scales was more accurate than… 
A multisite comparison of actuarial risk instruments for sex offenders.
Survival analyses revealed that those offenders high in both psychopathy and sexual deviance were an especially high-risk group, and predictive accuracy was higher for child molesters than for rapists.
Actuarial Assessment of Risk for Reoffense Among Adult Sex Offenders
This study extended previous research comparing a set of widely employed actuarial risk assessment schemes as well as a new instrument, the Static-2002, in a sample of 468 sex offenders followed for
Comparing Sex Offender Risk Classification Using the Static-99 and LSI-R Assessment Instruments
Objective: This study compares sex offender risk classification using two popular actuarial risk assessment instruments—the Static-99 and the Level of Service Inventory–Revised (LSI-R). Despite their
Actuarial Assessment of Sex Offender Recidivism Risk: A Cross-Validation of the RRASOR and the Static-99 in Sweden
Although particularly the Static-99 proved moderately robust as an actuarial measure of recidivism risk among sexual offenders in Sweden, both procedures may need further evaluation, for example, with sex offender subpopulations differing ethnically or with respect to offense characteristics.
Predictive Validity of the SVR-20 and Static-99 in a Dutch Sample of Treated Sex Offenders
The SVR-20 final risk judgment was a significantly better predictor of sexual recidivism than the Static-99 risk category.
Prediction of the risk of male sexual reoffending in Australia
Abstract This paper reports the findings of a retrospective study designed, primarily, to investigate the predictive accuracy of the Rapid Risk Assessment for Sexual Offence Recidivism (RRASOR); the
Comparing Sex Offender Risk Assessment Measures on a UK Sample
Forensic practitioners may be better served if risk measures assess specific subcategories of sexual offenders, particularly those with child victims who obtained significantly higher scores on the RRASOR.
The assessment of dynamic risk and recidivism in a sample of special needs sexual offenders
Abstract The predictive validity of four risk assessment instruments: the RRASOR, SVR-20, RM2000-V and the ARMIDILO-Stable and -Acute dynamic client subscales were assessed on a sample of 88
Actuarial risk assessment and recidivism in a sample of UK intellectually disabled sexual offenders
Abstract This study examines the effectiveness of three risk assessment instruments: Static-99, Risk Matrix 2000 (RM2000) and the Rapid Risk of Sex Offender Recidivism (RRASOR), in predicting sexual
Development of Vermont Assessment of Sex Offender Risk-2 (VASOR-2) Reoffense Risk Scale
The findings show the VASOR-2 is well calibrated with observed recidivism rates for all but the highest risk sex offenders, and the instrument showed good interrater reliability.


Actuarial Prediction of Sexual Recidivism
An actuarial approach to predicting sexual recidivism among known sex offenders is illustrated with a reanalysis of follow-up data of rapists and child molesters. One hundred seventy-eight sex
Predicting relapse: a meta-analysis of sexual offender recidivism studies.
The results suggest that applied risk assessments of sexual offenders should consider separately the offender's risk for sexual and nonsexual recidivism.
Violent recidivism: assessing predictive validity.
Until very recently, there has been little evidence of the ability of either clinicians or actuarial instruments to predict violent behavior. Moreover, a confusing variety of measures have been
Cross-Validation and Extension of the Violence Risk Appraisal Guide for Child Molesters and Rapists
Survition analyses showed that child molesters exhibited higher risk of sexual recidivism than rapists or offenders against both children and adults, whereas the opposite was true for violent recidivist, andportional hazards event history analyses supported the use of the VRAG for the prediction of violentRecidivism among sex offenders.
Meta-analytic techniques were used to determine which predictor domains and actuarial assessment instruments were the best predictors of adult offender recidivism. One hundred and thirty-one studies

Recidivism and readmission data were gathered over an average 46-month follow-up period on 54 rapists released from a maximum-security psychiatric hospital. The failure rates for subsequent

The aim of this study was to vefify whether static factors (criminal history, age, relationship status) and dynamic factors (deviance index based on phallometric data, score of psychometric testing)
Recidivism of Sexual Offenders: A Re-Appraisal
Few are likely to deny the relevance of the recidivism rates of sexual offenders in considering appropriate penal policy in relation to sexual offences. However, one should recognise from the outset

Past behavior alone appears to be a better long-term predictor of future behavior than clinical judgments and may also be a a better indicator than cross-validated actuarial techniques.

Evaluation of emotional congruence in men-homosexual and heterosexual pedophiles showed that only the homosexual pedophiles' scores indicated a preference for interacting with children on the child's level, while the incest offenders seemed to prefer to elevate their victims to adult status rather than fixating on theChild role themselves.
