“…The Stable-2007 coding manual consists of decision rules used to combine the Static-99R and Stable-2007. The reported AUCs for sexual recidivism in the original study (The Dynamic Supervision Project) of Static-99 was .74, Stable-2007 was .67, and the combination of Static-99 and Stable-2007 produced an overall increase in predictive validity which was found to be .76 (Hanson, Helmus, & Harris, 2015). The ICC of Stable-2007 is .79 on the total score (Fernandez et al, 2014).…”

The predictive validity of risk assessment instruments for persons who have committed sexual offenses has improved tremendously in the last four decades, but the progress has been limited to Western offender populations. The aim of this study was to examine the predictive validity of Static-99R, Stable-2007, Sexual Violence Risk-20, Version 2 (SVR-20 v2), Psychopathy Checklist—Revised (PCL-R), and Level of Service/Case Management Inventory (LS/CMI) in predicting recidivism of persons convicted on sexual offenses in Singapore. Retrospective data of 134 such persons were used to code the various instruments. Receiver operating characteristic analyses revealed that combined Static-99R/Stable-2007 new standardized risk ratings, SVR-20 v2 total scores and risk ratings, PCL-R total scores, as well as LS/CMI total scores and risk ratings predicted sexual recidivism. All the aforementioned instruments’ total scores and risk ratings (if applicable) predicted any recidivism. However, risk profiles of this sample differed significantly from the normative Western samples.

“…Static-99R and Static-2002R were developed on, and primarily intended for, individuals who are currently (or recently) serving a sentence for a sex offense. Two of the samples had not previously been used for STATIC norms (Hanson, Lunetta, Phenix, Neeley, & Epperson, 2014;Lehmann, Hanson, et al, 2013) and one was substantially updated (Hanson, Helmus, & Harris, 2015). For additional information, refer to Helmus (2009) and the original studies.…”

What Sexual Recidivism Rates Are Associated With Static-99R and Static-2002R Scores?

Empirical actuarial risk tools are routinely used to assess the recidivism risk of adult sexual offenders. Compared with other forms of risk assessment, one advantage of actuarial risk tools is that they provide recidivism rate estimates. Previous research, however, suggests that there is considerable variability in the recidivism rates associated with the most commonly used sexual offender risk assessment tools (Static-99/R, Static-2002/R). The current study examined the extent to which the variability in the recidivism rates across 21 Static-99R studies (N = 8,805) corresponded to the normative groups proposed by the STATIC development group (routine, treatment, high risk/high need). We found strong evidence that routine (i.e., complete) samples were, on average, less likely to reoffend with a sexual offense than offenders in the high-risk/high-need samples (i.e., those explicitly preselected on risk-relevant variables external to STATIC scales). The differences between routine/complete and high-risk/high-need samples, however, were only consistently observed for offenders with low or moderate scores; for offenders with high STATIC scores, the 5-year sexual recidivism rates for these two groups were not meaningfully different. There was only limited evidence to support treatment samples as a distinct sample type; consequently, the use of separate normative tables for treatment samples is not recommended. The current results reinforce the value of regularly updating the norms for empirical actuarial risk tools. Options are discussed on how STATIC scores could be used to inform recidivism rates estimates in applied assessments.

“…Etiological theories of risk for sexual offending also distinguish between more enduring psychological vulnerabilities, and risk states in which those vulnerabilities may have been RISK-RELATED CHANGE ON PAROLE triggered by contextual factors (Beech & Ward, 2004) This acute-stable distinction is reflected in some newer assessment tools (e.g., Stable-2007 andAcute-2007;Hanson, Harris, Scott, & Helmus, 2007;Hanson, Helmus, & Harris, (2015).…”

Few studies have examined change after treatment completion, despite the potential for such investigations to enhance our understanding of how a rehabilitative intervention leads to reduced recidivism. Newer statistical tools make it possible to describe and analyze patterns of change over multiple measurements, even with missing measurements and variable measurement intervals. The current study provides an example of the application of growth curve modeling in the context of assessing change in dynamic risk factors. We examined patterns of change in the community, following two samples of high-risk men for up to 12 months on parole; one had completed intensive psychological treatment, and the other completed no programs or briefer programs in prison. As expected, intensive program completers entered the community with higher protective factors and lower stable and acute dynamic factors, and showed less variability on acute risk factors, as did all of those with better initial scores. However, the two samples improved at a similar rate over the course of parole. Those with initially poorer scores changed less on parole except for protective factors; those with stronger initial protective scores showed less change.
