Multiple paraphilic diagnoses among sex offenders

The psychiatric literature suggests that paraphiliacs can be expected to participate in only one type of deviant sexual behavior. Using self-reports gathered with assured confidentiality from 561 nonincarcerated paraphiliacs, we discovered that most paraphiliacs have had significant experience with as many as ten different types of deviant sexual behavior without regard, in many cases, to gender, age, and familial relationship of the victim. The relevance of these findings to our understanding of paraphiliacs and their treatment is discussed.     

Male victims and post treatment risk assessment among adult male sex offenders

The use of actuarial instruments to predict sex offender recidivism has gained increasing credibility in recent years. This paper is one in a series examining the impact of dynamic inpatient group therapy upon the predictive influence of static risk factors on recidivism among adult sex offenders. Successful completion of the Phoenix Program (Alberta Hospital Edmonton) has been shown to ameliorate the influence of static risk factors on sexual offense recidivism. Many studies have reported that sex offenders who have male victims are more likely to re-offend than those who do not have male victims. A sample of N=513 convicted adult male sex offenders was examined regarding the relationship between the static risk factor of having male victims, subsequent re-offense, and treatment impact. Interestingly, ever having had a male victim did not significantly correlate with sex offense recidivism, for either treatment completers, non-completers, or the combined group. However, having exclusively male victims was correlated with sex offense recidivism, but only among non-completers of the program (r=.155; p=.017). Analysis of a subset of 422 child molesters yielded a similar result, in that having male victims exclusively was only associated with sex offense recidivism among treatment non-completers (r=.189, p=.009).     

Differential pharmacological treatment of paraphilias and sex offenders

This article gives an overview of current pharmacological treatment of paraphilias and sex offenders focusing on the situation in Germany. Information about selective serotonin reuptake inhibitors (SSRI) is followed by data about established antihormonal substances (cyproterone acetate/CPA, and medroxyprogesterone acetate/MPA), as well as a more detailed account on luteinizing hormone-releasing hormone agonists (LHRH agonists). The results of open, uncontrolled clinical studies with SSRIs (n = 16) and LHRH agonists (n = 11) in paraphilic outpatients confirm the positive effects of these substances. A survey about the use of CPA and LHRH agonists in forensic hospitals in Germany shows that half of the patients treated with any kind of (anti-) hormonal agents received an LHRH agonist. The authors present a protocol on side effects, contraindications, and monitoring of CPA and LHRH agonists and develop an algorithm for differential pharmacotherapy of paraphilias.     

Effectiveness of sex offender treatment for psychopathic sexual offenders

Meta-analyses have suggested that sexual offender treatment (SOT) completion is associated with lowered sexual recidivism rates for convicted sexual offenders. The paucity of properly designed studies allows for the alternative explanation of less recidivism among treated samples as reflecting that lower risk offenders disproportionately self-select into treatment. A test of the "self-selection explanation" can occur by investigating treatment effect on known high-risk offenders. Psychopathy correlates with increased sexual recidivism risk, such that an exploration of the SOT effect on psychopathic offenders could clarify the accuracy of the self-selection hypothesis. Additionally, the debated degree to which psychopaths are treatable might obtain clarification by a research review. This article examines empirical findings concerning the effectiveness of SOT for psychopathic sexual offenders. Ten studies were found to meet the minimal quality standards used, stemming from only four data sources. Shortcomings of existing research precluded clear conclusions, though trends in the data are delineated.     

Diagnostic and risk profiles among civilly committed sex offenders in Washington State

Since 1990, 17 states have passed legislation allowing for the civil commitment of a small number of sex offenders who are deemed at a particularly high risk for reoffense. Despite the very public and controversial nature of these laws, little is known about the individuals who are detained pursuant to them. The current article presents data on 190 civilly committed and detained sexually violent predators in Washington State. These sexual offenders suffer from a variety of mental illnesses. The modal offender is diagnosed with both an Axis I and an Axis II disorder. Furthermore, these offenders are at moderate to high risk for reoffense and present with a significant degree of psychopathy.     

Treatment of sex offenders with Depo-Provera

Medroxyprogesterone acetate (MPA) is capable of reducing male testosterone blood levels with a corresponding reduction in sexual interest and activity. An attempt to evaluate its effectiveness with court committed sexual offenders was made with eight subjects each serving as his own control by alternating Depo-Provera injections for 16 weeks with saline injections for a corresponding 16 weeks. This paper reports the results of this study and the conclusions that appear to be appropriate.     

Predictors of desistance among sex offenders: The interaction of formal and informal social controls

Increasing attention is being given to the issue of desistance or cessation in adult criminal careers. We contribute to this research by considering how informal and formal social controls affect recidivism among 556 sex offenders placed on probation in 1992. We conduct an event history analysis of reoffense, based on the predictions of Sampson and Laub's and Gottfredson and Hirschi's control theories. We build on these perspectives by examining how informal social controls condition the effects of formal social controls generally and across offense types. We find less recidivism among offenders with stable job histories, particularly among those in court-ordered sex offender treatment. The results add both to theoretical formulations concerning desistance and recidivism and to policy formulations directed at growing prison populations.     

Residential location and mobility of registered sex offenders

Identifying the residential locations of registered sex offenders is a major concern for contemporary policy makers and communities. The present study seeks to identify whether registered sex offenders’ residential locations at time of arrest differ from their current addresses, if registrants move whether they tend to move to more or less socially disorganized neighborhoods, as well as what factors are associated with moving to more or less socially disorganized areas. Data are analyzed for 271 registrants on 11 measures of community social disorganization variables. Findings indicate that registrants already residing in socially disorganized areas were less likely to have a downward movement to more socially disorganized areas. Also, those who resided in less socially disorganized areas initially were more likely to have downward movement to socially disorganized areas.     

A psychometric comparison of internet and non-internet sex offenders from a community treatment sample

Abstract

This paper compares psychometric test assessments of 39 men convicted of internet sex offences with 39 convicted of contact offences against a specific victim. Higher rates of socially desirable responding were identified in the internet group, as well as higher rates of emotional loneliness and under assertiveness, although the latter two findings were not statistically significant. This group also achieved lower scores measuring external locus of control, which might reflect their generally higher levels of education and employment (identified from research carried out in tandem with this work). The internet group achieved lower scores on sexualized attitudes towards children, emotional congruence with children and empathy distortions with regard to victims of child abuse. Hence, although they exhibited the kinds of general personality problems exhibited by other sex offenders, they did not support attitudes that explicitly endorse or condone the sexual abuse of children. This paper presents some hypotheses about these results and identifies further research necessary to develop understanding about this new kind of sexually abusive behaviour.     

Risk assessment with adolescent sex offenders

The paper describes an evaluation of a risk assessment tool's effectiveness in distinguishing adolescent sexual offenders who had committed further sexual offences from those who had not. The sample consisted of 50 male adolescent sexual offenders referred to a forensic outpatient service within a healthcare setting. The adolescents within the sample were designated recidivists versus non-recidivists using two methods: clinican's judgement and Home Office records for reconvictions. The risk assessment achieved a moderate to high level of sensitivity and specificity in distinguishing the recidivists from non-recidivists using clinician's judgement of recidivism as outcome. However, the tool was unable to distinguish recidivists from non-recidivists. The risk assessment tool described has potential in the identification and modification of contextual and clinical risk factors, in informing professionals’ decision-making and in developing and implementing a comprehensive risk management plan.     

Female sex offenders: severe victims and victimizers

Although there is an extensive body of literature concerning male sexual offenders, there is a marked lack of articles describing sexual offenses committed by females. The authors present a review of the existing literature on this topic and describe five cases of female sexual offenders and four cases of female sexual abusers. Implications for the effective assessment and treatment of this unique population are discussed.     

Public perception of sex offender social policies and the impact on sex offenders

This study examines the public perception of sex offender policies and the perceived impact of sex offender policies on the sex offenders themselves. Specifically, this study explores how the community feels about the effectiveness of policies such as registration and community notification (Megan's Law), and housing restrictions in reducing sexual recidivism. Data are collected from 115 participants from a nationwide online community message board. Results suggest that although most individuals support Megan's Law, they do not feel the policy reduces recidivism. Furthermore, the majority of the participants also do not believe that housing restriction statutes are effective in reducing sexual recidivism. When questioned about the policy impact on sex offenders, the majority of respondents agree that as a consequence of Megan's Law, sex offenders are afraid for their safety; however, they do not believe that residence restrictions hinder sex offenders' employment opportunities. Findings from this study are discussed as they pertain to public policy and sex offender reintegration.     

A 14- to 24-year longitudinal study of a comprehensive sexual health model treatment program for adolescent sex offenders: predictors of successful completion and subsequent criminal recidivism

The study determines the effectiveness of a sexuality-positive adolescent sexual offender treatment program and examines subsequent criminal recidivism in the three outcome groups (completed, withdrawn, referred). The sample consists of 122 adolescent males and their families (491 individuals). Of the demographic variables, only living situation was significant, such that patients living with parents were more likely to graduate. None of the behavioral variables were found to be significant. Of the treatment variables, length of time in the program and participation in the Family Journey Seminar were included in the final model. When they were included in the model, no other treatment variable were significantly related to probability of graduation. There were no arrests or convictions for sex-related crimes in the population of participants that successfully completed the program. This group was also less likely than the other groups to be arrested (p = 0.014) or convicted (p = 0.004) across all crime categories.     

Do sex offenders minimize psychiatric symptoms?

With increasing frequency, forensic psychiatrists are called upon to evaluate sex offenders for the courts and criminal justice system. While many clinicians have observed that denial of paraphilia is common in sex offenders, few studies have examined whether this population has severe psychopathology other than paraphilia. Similarly, little is known about whether sex offenders minimize or deny symptoms of psychopathology when undergoing psychiatric evaluations. To study these questions, the authors administered the Minnesota Multiphasic Personality Inventory (MMPI) to 36 sex offenders, comparing the degree to which they minimized or denied psychopathology, dividing subjects among two dimensions: (a) whether they admitted to, or denied, paraphilia, and (b) whether or not they faced legal charges for sex offense. Results indicated that, first, patients who denied paraphilia were significantly more likely to minimize psychopathology than were those who admitted to paraphilia (P less than 0.05); second, patients who faced no legal charges showed significantly more psychopathology than did those who faced charges (P less than 0.05); and third, the most frequent forms of psychopathology were antisocial attitudes, depressive features, somatization, and thought disorder. These findings suggest that many sex offenders may experience, and deny, widespread and severe psychiatric symptoms in addition to their sexual disorders.     

The significance of offending behavior for predicting sexual recidivism among sex offenders of various age groups

Based on a sample of 682 male sex offenders, this study investigated variables of the offending behavior for predicting sexual recidivism in different age groups. The sex offenders were allocated into four age groups. For each group, those characteristics of offending behavior showing a significant bivariate correlation with sexual recidivism were extracted. Using logistic regression, we then analyzed their incremental validity above and beyond a previously developed Crime Scene Behavior Risk (CBR)-Score, which measures the risk of sexual recidivism without taking into account the offenders' age (Dahle, Biedermann, Gallasch-Nemitz, & Janka, 2010). Age-specific offending behavior variables with incremental validity were combined with the general CBR-Score into age-specific scores and examined for their predictive accuracy. We also analyzed the extent in which these age-specific scores showed incremental validity above and beyond the Static-99 (Hanson & Thornton, 1999). For three of the four age groups, age-specific Crime Scene Behavior Risk-Scores could be determined which were incrementally valid above and beyond the Static-99. Predictive accuracy varied between AUC=.74 and AUC=.90 (r=.28 to r=.49) depending on age group. The results are discussed within context of recent findings on the latent dimensions of actuarial risk assessment variables.     

Isolation and normlessness: attitudinal comparisons of adolescent sex offenders, juvenile offenders, and nondelinquents

The authors explored attitudinal differences among adolescent male sex offenders, juvenile delinquents, and nondelinquent youth based on three variables drawn from integrated delinquency theory: conventional attitudes, normlessness, and social isolation. Consistent with previous juvenile delinquency studies, the results indicate no differences among the three groups on conventional attitudes. With respect to normlessness, both the sex offenders and juvenile delinquent groups demonstrated more school normlessness than did nondelinquent youths, and adolescent sex offenders showed greater peer normlessness than did either nondelinquent youths or juvenile delinquents. Examination of perceived social isolation among the three groups indicates that sex offenders consistently perceived themselves as more isolated than other youths with their families, in their school, and among their peers. These results suggest that interpersonal factors, in addition to a lack of social controls and normlessness, are associated with sexually inappropriate behavior.     

Application of the clinical polygraph examination to the assessment,treatment and monitoring of sex offenders

Abstract

Post Conviction Clinical Polygraph Examination Testing (Lie Detector Testing) offers significant opportunities for assessing, treating and monitoring sex offenders. This article briefly reviews the historical development of polygraph techniques including the physiological measures employed, the administration of the polygraph and the interpretation of data collected. Criticisms of polygraphy are explored and information concerning the scientific acceptability of these procedures is given. The current influence of polygraphy in sex offender work is reviewed. Evidence is given of the utility of polygraphy in reducing denial, improving treatment outcomes and more effectively supervising sex offenders on probation or license. Cost benefit considerations are examined, as well as the need for further controlled research and future regulation of the polygraph, if it is to be introduced in Britain. Planned UK Trials are described.
