Where Should We Intervene, 20 Years Later? Case–Control and Prospective Cohort Designs Provide Similar Answers
In 2000, this journal published an influential case–control study identifying dynamic risk factors for sexual recidivism (Hanson & Harris, 2000). In 2017, updated recidivism information for the same sample was obtained with an average follow-up of 20 years. The current study compared the risk factors that differentiated between sexual recidivists and nonrecidivists between the two research designs: original case–control and updated prospective co…
How public registries obscure sexual recidivism risk: Evidence from state administrative data
Acute-2007 and STABLE-2007 predict recidivism for men adjudicated for child sexual exploitation material offending
OBJECTIVE: Risk assessment is essential to effective correctional practice. For individuals with contact sexual offenses, many risk tools are available. There are fewer options, however, for individuals whose sexual offending exclusively involves child sexual exploitation materials (CSEM; legally referred to in Canada and the United States as child pornography). HYPOTHESES: The present study examined the predictive validity of the ACUTE-2007 and …
Does Reassessment Improve Prediction? A Prospective Study of the Sexual Offender Treatment Intervention and Progress Scale (Sotips)
This prospective study examined the predictive validity of the Sex Offender Treatment Intervention and Progress Scale (SOTIPS; McGrath et al., 2012), a sexual recidivism risk/need tool designed to identify dynamic (changeable) risk factors relevant to supervision and treatment. The SOTIPS risk tool was scored by probation officers at two sites ( n = 565) for three time points: near the start of community supervision, at 6 months, and then at 12 m…
Updated 5-year and new 10-year sexual recidivism rate norms for Static-99R with routine/complete samples
The current study provides empirical evidence to estimate 5- and 10-year sexual recidivism rates based on Static-99R total scores. Evaluators who are especially concerned about long-term sexual recidivism risk (e.g., civil commitment) can report the expected sexual recidivism risk based on the new 10-year norms and the extrapolated sexual recidivism rates for follow-up periods of 11 to 20 years.

Online Child Pornography Offenders are Different: A Meta-analysis of the Characteristics of Online and Offline Sex Offenders Against Children
Attitudes Supportive of Sexual Offending Predict Recidivism: A Meta-Analysis
Attitudes supportive of sexual offending figure prominently in theories of sexual offending, as well as in contemporary assessment and treatment practices with sex offenders. Based on 46 samples ( n = 13,782), this meta-analysis found that attitudes supportive of sexual offending had a small, yet reasonably consistent, relationship with sexual recidivism (Cohen’s d = .22). To the extent that differences were observed, attitudes predicted recidivi…
Assessing Risk for Sexual Recidivism: Some Proposals on the Nature of Psychologically Meaningful Risk Factors
Risk assessment and treatment for sexual offenders should focus on individual characteristics associated with recidivism risk. Although it is possible to conduct risk assessments based purely on empirical correlates, the most useful evaluations also explain the source of the risk. In this review, the authors propose that the basic requirements for a psychologically meaningful risk factor are (a) a plausible rationale that the factor is a cause of…

The Principles of Effective Correctional Treatment Also Apply To Sexual Offenders: A Meta-Analysis
The effectiveness of treatment for sexual offenders remains controversial, even though it is widely agreed that certain forms of human service interventions reduce the recidivism rates of general offenders. The current review examined whether the principles associated with effective treatments for general offenders (risk-need-responsivity; RNR) also apply to sexual offender treatment. Based on a meta-analysis of 23 recidivism outcome studies meet…

Where Should We Intervene?: Dynamic Predictors of Sexual Offense Recidivism
Effective intervention with sexual offenders requires the targeting of appropriate risk factors. In this study, information on dynamic (changeable) risk factors was collected through interviews with community supervision officers and file reviews of 208 sexual offense recidivists and 201 nonrecidivists. The recidivists were generally considered to have poor social supports, attitudes tolerant of sexual assault, antisocial lifestyles, poor self-ma…
Improving risk assessments for sex offenders: A comparison of three actuarial scales.
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 combin…
