Pornography use and sexual aggression: the impact of frequency and type of pornography use on recidivism among sexual offenders

In this study, we examined the unique contribution of pornography consumption to the longitudinal prediction of criminal recidivism in a sample of 341 child molesters. We specifically tested the hypothesis, based on predictions informed by the confluence model of sexual aggression that pornography will be a risk factor for recidivism only for those individuals classified as relatively high risk for re-offending. Pornography use (frequency and type) was assessed through self-report and recidivism was measured using data from a national database from the Royal Canadian Mounted Police. Indices of recidivism, which were assessed up to 15 years after release, included an overall criminal recidivism index, as well as subcategories focusing on violent (including sexual) recidivism and sexual recidivism alone. Results for both frequency and type of pornography use were generally consistent with our predictions. Most importantly, after controlling for general and specific risk factors for sexual aggression, pornography added significantly to the prediction of recidivism. Statistical interactions indicated that frequency of pornography use was primarily a risk factor for higher-risk offenders, when compared with lower-risk offenders, and that content of pornography (i.e., pornography containing deviant content) was a risk factor for all groups. The importance of conceptualizing particular risk factors (e.g., pornography), within the context of other individual characteristics is discussed.

The importance of individual differences in pornography use: theoretical perspectives and implications for treating sexual offenders.

This article reviews the extant literature regarding pornographys influence on antisocial attitudes, sexual arousal, and sexually aggressive behavior in both noncriminal and criminal samples. The article concludes that when examined in the context of multiple, interacting factors, the findings are highly consistent across experimental and nonexperimental studies and across differing populations in showing that pornography use can be a risk factor for sexually aggressive outcomes, principally for men who are high on other risk factors and who use pornography frequently. Finally, this article presents theoretical implications based on these findings, as well as some clinical implications relevant to the assessment and treatment of sexual offenders.

Problematic Hypersexuality: A Review of Conceptualization and Diagnosis

There has been considerable debate regarding the conceptualization and diagnosis of individuals exhibiting problematic hypersexuality. Various terms such as sexual addiction, sexual compulsivity, and sexual impulsivity have been applied based predominantly on the perceived psychopathological mechanisms guiding the behavior. Unfortunately, such descriptive diversity has inhibited adequate conceptualization and current diagnostic practices, which in turn, have negatively impacted treatment design. This paper critically reviews the extant literature regarding the conceptualization and diagnosis of problematic hypersexuality. Additionally, this review highlights the utility of a relatively new conceptualization of problematic hypersexuality, the Sexual Desire Disorders model, which accounts for many of the limitations inherent in previous explanatory models. Finally, diagnostic, conceptual, and treatment implications are discussed.

Are the cognitive distortions of child molesters in need of treatment

Abstract This paper challenges accepted notions about the importance of cognitive distortions expressed by child molesters. First, we consider the role of excuse-making in a healthy life, and as a result question whether it is in the best interests of our clients to challenge their distortions. We examine the literature on eyewitness reports and the reconstructive nature of memory to call into question the value of requiring child molesters’ reports of their offence to match the victims account. Next we show that the evidence does not demonstrate convincingly that cognitive distortions are criminogenic. Furthermore, the responses of child molesters to measures of cognitive distortions indicate that they simply endorse less disagreement with the items than do others. However, we note that some of these distortions, while not criminogenic, may nevertheless interfere with the acquisition of skills for important treatment targets (e.g. relationships). We offer suggestions for the most effective way to elicit and change these distortions.

Comparing indicators of sexual sadism as predictors of recidivism among adult male sexual offenders.

OBJECTIVE In this longitudinal study, the predictive validity of a psychiatric diagnosis of sexual sadism was compared with three behavioral indicators of sadism: index sexual offense violence, sexual intrusiveness, and phallometrically assessed sexual arousal to depictions of sexual or nonsexual violence. METHOD Five hundred and eighty six adult male sexual offenders were assessed between 1982 and 1992, and these offenders were followed for up to 20-years postrelease via official criminal records. Assessment information included the Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnosis, offense characteristics, phallometric assessment results, and an actuarial risk measure (the Sex Offender Risk Appraisal Guide). RESULTS Predictive validity was demonstrated in univariate analyses for the behavioral indicators of sexual sadism (area under the curve [AUCs] from .58 to .62) but not psychiatric diagnosis (AUC = .54). Cox regression analyses revealed that phallometrically assessed sexual arousal to violence was still significantly associated with violent (including sexual) recidivism after actuarially estimated risk to reoffend was controlled. A psychiatric diagnosis of sexual sadism, in contrast, was unrelated to recidivism. CONCLUSIONS The results support the use of more behaviorally operationalized indicators of sexual sadism, especially phallometric assessment of sexual arousal, and suggest the DSM criteria for sexual sadism require further work.

Long-Term Predictive Validity of the Risk Matrix 2000 A Comparison With the Static-99 and the Sex Offender Risk Appraisal Guide

The purpose of this study is to examine the predictive accuracy of the Risk Matrix 2000 on an independent sample of 351 sexual offenders, followed in the community for an average duration of 11.4 years (range 0-20 years, SD = 4.4 years). For comparison purposes, this study also examines the predictive accuracy of two other risk assessment instruments, specifically modified versions of the Static-99 and the Sex Offender Risk Appraisal Guide (SORAG). Results indicate that the Risk Matrix 2000 demonstrates convergent validity by correlating with the other risk assessment instruments. Moreover, the Risk Matrix 2000 is predictive of recidivism above chance levels, exhibiting medium to large effect sizes, although in general, the other two instruments, particularly the SORAG, are superior. Results also indicate differences in predictive validity when comparing 2-year, 5-year, and variable follow-up periods. Finally, a cumulative meta-analysis compares and integrates current findings with those obtained from the accumulation of previous studies, and new cumulative estimates are provided.

Factors associated with recidivism among intrafamilial child molesters.

Abstract This study examined factors that could potentially differentiate between sexual, violent and criminal recidivist and non-recidivist incest offenders (n=295). The objective of the study was to extend a previous study conducted on incest offenders by increasing the sample size, adding seven years to the follow-up and attempting to address some of the limitations identified in the previous study. Results indicated, that by the end of the 19th year (mean=10.78), 9.8%, 20% and 27.5% of incest offenders were charged or convicted of a sexual, violent or criminal offence, respectively. This study identified a number of predictor variables demonstrating either moderate or strong associations with recidivism (i.e. Cohens effect size), some of which are changeable and, thus, should be considered important treatment targets for this type of offender. Specifically, sexual recidivists had higher psychopathy scores than non-recidivists. Violent recidivists were younger, demonstrated more problems with alcoholism, were more hostile, had higher psychopathy scores and had more previous criminal charges and/or convictions than non-recidivists. Finally, criminal recidivists were younger, demonstrated more problems with alcoholism, were more hostile, had higher psychopathy scores and had more previous violent and criminal charges and/or convictions than non-recidivists.

A multisite examination of sexual violence risk and therapeutic change.

OBJECTIVE We conducted a prospective multisite examination of sexual offender risk and treatment change on a large federal Canadian sample of 676 treated sex offenders followed up for an average of 6.31 years post release. METHOD The present study featured the clinical application of a risk assessment and treatment planning tool, the Violence Risk Scale-Sexual Offender version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003). The VRS-SO was rated pre- and posttreatment by sex offender treatment providers on the sample of men who were attending institutionally based sex offender programs across the 5 regions of the Correctional Service of Canada. The Static-99 (Hanson & Thornton, 1999) was also rated as part of routine services, and the Static-99R was used for substantive analyses. RESULTS The VRS-SO dynamic factors and the Static-99R demonstrated significant predictive accuracy for sexual, violent, and general recidivism (area under the curve = .65 to .78). Significant pre-post changes on the VRS-SO dynamic factors were observed, ranging from small to moderate in magnitude (d = 0.22 to 0.62) across low, moderate, and high intensity programs. The change scores, in turn, were associated with decreases in the 3 recidivism outcomes; the majority of relationships examined attained significance after partialing out of pretreatment scores. Cox regression survival analyses, controlling for pretreatment risk, further demonstrated change scores to have associations with postrelease recidivism outcomes to varying degrees. CONCLUSIONS The results are consistent with the dynamic nature of sexual violence risk and suggest that risk-relevant changes associated with participation in sexual offender treatment are linked to reductions in sexual offender recidivism.

Hypersexuality and Recidivism among Sexual Offenders

Hypersexuality is a dimensional indicator of sexual interest and behavior and typically includes the frequency, intensity, and time consumed by sexual activity. Hypersexuality has been identified as a psychologically meaningful risk factor for sexual offending. In fact, a relatively high proportion of sexual offenders report hypersexual behavior and this construct seems to be associated with re-offending in these men. The purpose of the present longitudinal investigation was to examine the rate of an objective, behavioral indicator of hypersexuality (Total Sexual Outlet) among 586 adult male sexual offenders and to determine the predictive utility of Total Sexual Outlet utilizing one of the longest follow-up periods used with sexual offenders (up to 20 years). Results indicated that approximately 12% of men met the clinical criterion for hypersexuality and that the presence of this construct was significantly associated with long-term sexual and violent recidivism. Results are discussed in terms of the importance of hypersexuality as an empirically supported risk factor and treatment target among sexual offenders.

A Description of Sexual Offending Committed by Canadian Teachers.

The aim of this investigation was to describe teachers who sexually offend against youth and the circumstances related to these offenses. Archival Violent Crime Linkage Analysis System reports were obtained from the Royal Canadian Mounted Police, and demographic and criminal characteristics for the offender, as well as information about the victim and offense, were selected for analyses. A descriptive approach was used to analyze the qualitative reports for a group of 113 Canadian sexual offenders between 1995 and 2002. The results provide a description of adult male teachers who offended within their position of trust as well as offense and victim characteristics.
