The role of central and peripheral hormones in sexual and violent recidivism in sex offenders.

Hormonal factors are important in multifactorial theories of sexual offending. The relationship between hormones and aggression in nonhumans is well established, but the putative effect in humans is more complex, and the direction of the effect is usually unclear. In this study, a large sample (N = 771) of adult male sex offenders was assessed between 1982 and 1996. Gonadotrophic (follicle-stimulating hormone and luteinizing hormone) and androgen hormone (total and free testosterone; T) levels were assessed at Time 1, along with indicators of sex drive and hostility. Individuals were observed up to 20 years in the community, with an average time at risk of 10.9 years (SD 4.6). Gonadotrophic hormones correlated positively with self-reported hostility and were better predictors of recidivism than was T (area under the curve (AUC), 0.58-0.63). Self-reported hostility emerged as a partial mediator of this relationship between gonadotrophic hormones and recidivism. These results point to a potentially new area of investigation for hormones and sexual aggression.

The self-regulation model of sexual offending: Relationship to risk and need.

In the present study, we evaluated the validity and utility of the self-regulation model in a sample of 275 adult male sexual offenders treated within the Correctional Service of Canada (CSC). Individuals following different self-regulation pathways, as delineated in the SRM, were compared on offence characteristics, static and dynamic risk measures, and various treatment targets. Multivariate analyses revealed that, in general, offenders guided by approach-motivated goals exhibited more problematic offence characteristics as well as greater risk and treatment need than individuals guided by inhibitory goals. However, several other important distinctions were noted across offenders with different goals and strategies toward offending. These findings highlight the main importance of utilizing a comprehensive and multidimensional offence process model that emphasizes multiple routes to offending in sexual offender treatment. Implications of these findings for the effective assessment and rehabilitation of sexual offenders are discussed.

Therapist awareness and responsibility in working with sexual offenders.

The article aims to address the ethical implications of therapist reactions to sexual offender treatment and, in doing so, increase awareness and understanding of the interaction between the clinician and the challenges of working with sexual offenders. The effects of providing psychological services in general, and to sexual offenders specifically, are reviewed, including the impact on services provided. Practice implications are also discussed as the authors consider the negative effects (e.g., burnout) that therapists experience due to treatment quality and the ethical issues and responsibilities surrounding clinical reactions. Finally, the authors summarize research on self-care and practice recommendations for effectively and ethically working with sexual offenders.

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.

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.

Clerics who commit sexual offenses: offender, offense, and victim characteristics.

The aim of this investigation was to undertake an exploratory analysis of clerics who sexually offend and the circumstances related to these offenses. Thirty-three adult male religious leaders who had been charged with a sexual offense against a child or adolescent were included in the study. This study examined descriptive information about offenders, their victims, as well as characteristics of the crimes. Notable trends included the following: religious leaders tended to offend against boys living with both parents, the offense often took place at the clergy's residence, and the offense involved fondling the victim. The study also compared offenders with single versus multiple victims on crime variables and differences were noted with respect to victim access.

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.

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.

Changes in coping following treatment for child molesters.

Relapse prevention theory assumes that specific coping skills deficits contribute to sexual reoffending. Recent research suggests that the general coping style of sexual offenders is also ineffective. In this study changes were examined in specific and general coping deficits following a treatment program that incorporated specific skills training as well as modifying general styles. Treated incarcerated child molesters were compared to a group of incarcerated child molesters on a waiting list for treatment. Groups completed various measures aimed at identifying coping strategies used in specific high-risk situations and general coping styles. Compared to the waiting list group, treated child molesters identified more effective coping strategies in specific high-risk situations. Changes are noted in their general coping styles with an increase in the endorsement of task-focused strategies and social diversion strategies. No changes in their endorsement of ineffective strategies such as emotion-focused or distraction strategies occurred. Implications for treatment are discussed.

Child care providers who commit sexual offences: a description of offender, offence, and victim characteristics.

The aim of this investigation was to undertake an exploratory analysis of child care providers who sexually offend against children and adolescents and the circumstances related to these offences. Archival Violent Crime Linkage Analysis System (ViCLAS) reports were obtained from the Royal Canadian Mounted Police (RCMP), and demographic and criminal characteristics for the offender, as well as information about the victim and offence, were selected for analyses. A descriptive approach was used to analyze the qualitative reports for a group of 305 Canadian sexual offenders between 1995 and 2002. Adult male (N = 163) and female ( N = 14), along with juvenile male (N = 100) and female (N = 28) child care providers who were involved in a sexual offence against a child or adolescent are described. This article provides unique information about the crimes committed by child care providers in that it is focused on crime characteristics, rather than on personality or treatment variables. Furthermore, it represents a comprehensive examination of this type of offender by including understudied groups, namely juvenile and female offenders.

Denial predicts recidivism for some sexual offenders.

This study examined whether there were variables that moderated the relationship between denial and recidivism among adult male sexual offenders. The first study (N = 489) found that the relationship with sexual recidivism was moderated by risk (as measured by the Rapid Risk Assessment for Sexual Offense Recidivism) but not by psychopathy (as measured by the Psychopathy Checklist-Revised). Contrary to expectations, denial was associated with increased sexual recidivism among the low-risk offenders and with decreased recidivism among the high-risk offenders. Post hoc analyses suggested that the risk item most responsible for the interaction was "relationship to victims". For incest offenders, denial was associated with increased sexual recidivism, but denial was not associated with increased recidivism for offenders with unrelated victims. These interactions were substantially replicated in two independent samples (N = 490 and N = 73). The results suggest that denial merits further consideration for researchers as well as those involved in applied risk assessment of sexual offenders.

Vicarious traumatization: the impact on therapists who work with sexual offenders.

This article reviews the descriptive and empirical literature examining vicarious traumatization in therapists treating sexual offenders. Vicarious traumatization in sexual offender therapists is described, including an examination of the relationships between vicarious traumatization and client, therapist, and setting and therapy characteristics. Special attention is given to those unique factors that contribute to the development of vicarious traumatization in this group, as well as consideration of why therapists treating offenders or victims may differ in their experience and development of vicarious traumatization. Evidence from the research reviewed suggests that sexual offender therapists do experience symptoms of vicarious traumatization. Factors most strongly associated with the development of vicarious traumatization in sexual offender therapists include professional experience, treatment setting, and coping strategies employed by the therapists. Implications and recommendations for professionals and policymakers are discussed.

Incarceration and recidivism among sexual offenders.

The relationship between incarceration and recidivism was investigated in a sample of 627 adult male sexual offenders. Incarceration for the index offense was unrelated to sexual or violent recidivism. This was the case whether incarceration was examined as a dichotomous variable (incarceration vs. community sentence) or as a continuous variable (length of incarceration). Risk for sexual recidivism was assessed with a modified version of the Rapid Risk Assessment for Sexual Offense Recidivism. There was no evidence that the relationship between incarceration and recidivism was confounded or moderated by risk or that length of incarceration and recidivism were non-linearly associated. Sentencing sexual offenders to terms of incarceration appears to have little, if any, impact on sexual and violent recidivism following release.

The utility of the diagnosis of pedophilia: a comparison of various classification procedures.

This study examined the utility of the diagnosis of pedophilia in a sample of extra-familial child molesters assessed at a university teaching hospital between 1982 and 1992. Pedophilia was defined in one of four ways: (1) DSM diagnosis made by a psychiatrist; (2) deviant phallometric profile; (3) DSM diagnosis and a deviant phallometric profile; and, (4) high scores based on the Screening Scale for Pedophilic Interest (Seto & Lalumière, 2001). Demographic data, psychological tests, and offence history were obtained and group differences were analyzed along with the ability of certain variables to contribute uniquely to the classification of pedophilia. Results indicated that few significant differences existed on psychological measures between pedophilic and nonpedophilic extra-familial child molesters regardless of the classification system employed. Finally, results indicated that the procedures used to define pedophilia were not significantly related to one another. Results are discussed in terms of the utility of the diagnosis of pedophilia.

Long-term follow-up of exhibitionists: psychological, phallometric, and offense characteristics.

Exhibitionism has historically been viewed as more of a nuisance than a serious criminal justice matter. Research has demonstrated that the number of exhibitionists who are detected re-offending is a significant under-representation of the number who actually re-offend. The objective of this study was to extend a previous study conducted on exhibitionists, while attempting to solve the limitations described in that study. Two hundred eight exhibitionists were assessed at a university teaching hospital between 1983 and 1996. Archival data were derived from police and medical files. Results indicated that, over a mean follow-up period of 13.24 years, 23.6, 31.3, and 38.9 percent of exhibitionists were charged with or convicted of sexual, violent, or criminal offenses, respectively. Undoubtedly, this is an under-representation of the true rate, as we have no way of knowing how many exhibitionists re-offended and did not get caught. Nevertheless, in the present investigation, sexual recidivists compared with non-recidivists were less educated, scored higher on the Michigan Alcohol Screening Test (MAST), the Psychopathy Checklist, Revised (PCL-R), and the Pedophile Index. Violent recidivists were also less educated and scored higher on the MAST, PCL-R, and the Pedophile Index, and had accumulated a greater number of prior violent or criminal charges and/or convictions. Criminal recidivists were less educated; scored higher on the MAST, Buss-Durkee Hostility Inventory (BDHI), PCL-R, and Pedophile Index; and had accumulated a greater number of prior sexual, violent, and criminal offenses. Finally, the hands-on sexual recidivists accumulated a greater number of prior violent and criminal charges and or convictions than did the hands-off sexual recidivists.

Hostility and recidivism in sexual offenders.

In this study, we examined the association of hostility, as measured by the Buss-Durkee Hostility Inventory (BDHI), with offence characteristics and recidivism in 656 adult male sexual offenders. Hostility was significantly associated with having prior violent charges, the use of violence in the index sexual offence, sexual recidivism, and violent recidivism. After controlling for risk level, as measured by a modified version of the Rapid Risk Assessment for Sexual Offence Recidivism (RRASOR-mod), the significant association between hostility and sexual and violent recidivism remained. When examined by type of offender, hostility was significantly associated with recidivism in intrafamilial and extrafamilial child molesters, but not in rapists or mixed offenders. Given the predictive value of hostility independent of the RRASOR-mod, the present findings confirm and encourage treatment efforts directed toward the management of hostility and anger in sexual offenders.

A comparison of incest offenders based on victim age.

The purpose of the present study was to compare incest offenders (IOs) whose victims include infants or toddlers to IOs with adolescent victims on several variables commonly examined in the sexual offender literature. Participants were 48 men whose youngest victim was less than 6 years of age (younger-victim incest offenders; YVs); and 71 men whose youngest victim was 12 to 16 years of age (older-victim incest offenders (OVs). In general, YVs showed more emotional disturbance and pathology than OVs. Compared with OVs, YVs had a greater history of substance abuse and more current problems with alcohol. In addition, YVs reported significantly poorer sexual functioning and were significantly more psychiatrically disturbed. YVs were also more likely to have a male victim, to have victimized a nephew/niece or grandson/granddaughter, and to have denied their offense(s). It was evident that both the YVs and OVs demonstrated clinically significant difficulty with normal sexual functioning and exhibited deviant sexual arousal.

Biological fathers and stepfathers who molest their daughters: psychological, phallometric, and criminal features.

A sample (N=143) of men who sexually abused their biological daughters or their step/adopted daughters were examined on a comprehensive array of demographic and historical information, offense characteristics, psychological and phallometric measures, and recidivism. Biological fathers were significantly less sexually aroused by children than were the stepfathers. On all the remaining variables, however, no statistically significant differences were found. Overall, biological and stepfathers in the present study appear to be much more similar than different from one another.

Prediction of recidivism in exhibitionists: psychological, phallometric, and offense factors.

Exhibitionists have traditionally been regarded as nuisance offenders. However, empirical studies show that some offenders can be highly recidivistic and can escalate to incidents of Hands-on sexual assault. The objective of this study was to investigate predictors of recidivism in exhibitionists and clarify the differences between Hands-on and Hands-off sexual recidivists. The hundred and twenty-one exhibitionists were assessed at a university teaching hospital between 1983 and 1996. Archival data came from medical files and police files. The Psychopathy Checklist-Revised (PCL-R) was assessed retrospectively. Results indicated that over a mean follow-up period of 6.84 years, 11.7, 16.8, and 32.7% of exhibitionists were charged with or convicted of sexual, violent, or criminal offenses, respectively. Sexual reoffending recidivists were less educated, and had more prior sexual and criminal offenses. Violent, recidivists were also less educated, had lower Derogatis Sexual Functioning Inventory (DSFI) scores, higher PCL-R Totals, and more prior sexual, violent, and criminal offenses. Criminal recidivists were younger, less educated, had lower DSFI scores, higher PCL-R scores, higher Pedophile Indices, and more prior sexual, violent, and criminal offenses. Hands-on sexual recidivists demonstrated higher PCL-R ratings, higher Pedophile and Rape indices, and more prior sexual, violent, and criminal offenses than did Hands-off counterparts.

A comparison of modified versions of the Static-99 and the Sex Offender Risk Appraisal Guide.

The predictive validity of 2 risk assessment instruments for sex offenders, modified versions of the Static-99 and the Sex Offender Risk Appraisal Guide, was examined and compared in a sample of 258 adult male sex offenders. In addition, the independent contributions to the prediction of recidivism made by each instrument and by various phallometric indices were explored. Both instruments demonstrated moderate levels of predictive accuracy for sexual and violent (including sexual) recidivism. They were not significantly different in terms of their predictive accuracy for sexual or violent recidivism, nor did they contribute independently to the prediction of sexual or violent recidivism. Of the phallometric indices examined, only the pedophile index added significantly to the prediction of sexual recidivism, but not violent recidivism, above the Static-99 alone.
