The Violence Risk Scale-Sexual Offender version (VRS-SO) is a rating scale designed to assess risk and predict sexual recidivism, to measure and link treatment changes to sexual recidivism, and to inform the delivery of sexual offender treatment. The VRS-SO comprises 7 static and 17 dynamic items empirically or conceptually linked to sexual recidivism. Dynamic items with higher ratings identify treatment targets linked to sexual offending. A modified stages of change model assesses the offender's treatment readiness and change. File-based VRS-SO ratings were completed on 321 sex offenders followed up an average of 10 years post-release. VRS-SO scores predicted sexual and nonsexual violent recidivism post-release and demonstrated acceptable interrater reliability and concurrent validity. A factor analysis of the dynamic items generated 3 factors labeled Sexual Deviance, Criminality, and Treatment Responsivity, all of which predicted sexual recidivism and were differentially associated with different sex offender types. The dynamic items together made incremental contributions to sexual recidivism prediction after static risk was controlled for. Positive changes in the dynamic items, measured at pre- and posttreatment, were significantly related to reductions in sexual recidivism after risk and follow-up time were controlled for, suggesting that dynamic items are indeed dynamic or changeable in nature.

There is some evidence that testosterone-lowering medications (TLM) may be an effective treatment for men convicted of sexual offenses by attenuating paraphilic sexual fantasies and behaviors and reducing the recidivism risk. To date, however, only little is known about the effects of TLM stopping on risk-relevant aspects. Therefore, the current study aimed at examining the recidivism risk as measured by Stable-2007 as well as official records of reoffenses in 29 men having stopped TLM treatment as compared to 37 men with ongoing TLM treatment.

It is crucial to assess the predictive validity of traditional risk factors in individuals engaged in online child exploitation. This study examines recidivism rates and risk factors among individuals involved in online child sexual exploitation, analyzing data from a sample of 228 adult males who had committed sexual and nonsexual offenses at their index crime.

It is common for forensic evaluators to use assessment instruments in risk assessment evaluations. This study examines whether different evaluators use instrument results the same way when coming to conclusions about risk for sexual recidivism in Sexually Violent Predator (SVP) evaluations. Three evaluators who each used both the Static-99R and Psychopathy Checklist-Revised in more than 60 SVP evaluations (Total = 338) provided data for the study.

Despite increases in online child sexual exploitation (OCSE) internationally, no study has examined risk factors for re-offending among females who perpetrate OCSE, resulting in limited knowledge regarding the idiosyncratic needs of this cohort. This study explored factors predictive of further police contact among 116 females known to police for OCSE offenses in Victoria, Australia. Four binary regressions were run for each of Any, Violent, and Non-Violent re-offending, with one regression each focusing on characteristics related to offending history, index offending, co-offending, and victimization.
