Sexual offender recidivism risk: what we know and what we need to know.
ABSTRACT If all sexual offenders are dangerous, why bother assessing their risk to reoffend? Follow-up studies, however, typically find sexual recidivism rates of 10%-15% after five years, 20% after 10 years, and 30%-40% after 20 years. The observed rates underestimate the actual rates because not all offences are detected; however, the available research does not support the popular notion that sexual offenders inevitably reoffend. Some sexual offenders are more dangerous than others. Much is known about the static, historical factors associated with increased recidivism risk (e.g., prior offences, age, and relationship to victims). Less is known about the offender characteristics that need to change in order to reduce that risk. There has been considerable research in recent years demonstrating that structured risk assessments are more accurate than unstructured clinical assessments. Nevertheless, the limitations of actuarial risk assessments are sufficient that experts have yet to reach consensus on the best methods for combining risk factors into an overall evaluation.

ABSTRACT: Despite an extensive research literature on sexual offending, much of current sexual offender policy within the United States runs counter to such literature, and instead, is based on common, pervasive myths about sexual offenders. Not surprisingly, recent studies on sex offender policy effectiveness suggest that current approaches are both costly and largely ineffective. In this paper, we suggest that a longstanding socio-cultural climate of sex-negativity fuels common fears and misconceptions about sexual offending and about policy related to treatment and supervision. We present a positive sexuality model and consider how the effectiveness of dealing with sexual offending issues could be improved through using a positive sexuality approach to guide policy.Critical Criminology 01/2015; DOI:10.1007/s10612-015-9270-y

ABSTRACT: Many studies have validated the psychometric properties of the Static-99, the most widely used measure of sexual offender recidivism risk. However much of this research relied on instrument coding completed by well-trained researchers. This study is the first to examine the interrater reliability (IRR) of the Static-99 between practitioners in the field and researchers. Using archival data from a sample of 1,973 formerly incarcerated sex offenders, field raters' scores on the Static-99 were compared with those of researchers. Overall, clinicians and researchers had excellent IRR on Static-99 total scores, with IRR coefficients ranging from "substantial" to "outstanding" for the individual 10 items of the scale. The most common causes of discrepancies were coding manual errors, followed by item subjectivity, inaccurate item scoring, and calculation errors. These results offer important data with regard to the frequency and perceived nature of scoring errors.International Journal of Offender Therapy and Comparative Criminology 07/2013; 58(11).
