Sexual predators and prey: a comparative study of the hunting behavior of rapists and child molesters

Although there has been an increase in research on sex offenders' modus operandi, geographic decision making, and hunting behavior, most studies still tend to emphasize criminal motivation while overlooking the role of situational and environmental factors. Studies of mixed samples of rapists and child molesters typically neglect to conduct comparative analyses. Consequently, the full nature of their distinction is not clear. This is particularly problematic for the understanding of crossover or polymorphous sex offenders, who target victims from various age groups. Using a sample of 216 incarcerated sexual offenders, hunting behavior patterns were identified and tested to establish which hunting behavior patterns were associated with each type of offender. Relationships between modus operandi, geographic decision making, and hunting behavior were also examined. Three types of offender were identified: (a) manipulative; (b) opportunist; and (c) coercive. The manipulative offender is typically a child molester. The coercive offender is typically a rapist. The opportunist offender includes both rapists and child molesters. These findings emphasize the relevance of polymorphous, crossover, or versatile sex offenders and suggest new ways of conceptualizing sex offenders and their study.     

A critique of current child molester subcategories: a proposal for an alternative approach

This paper examines the utility of previous attempts to subcategorize child molesters. We argue that research based on these categorizations has resulted in confusion due to differences across studies concerning which offenders belong in each group. For example, there are no agreed-upon guidelines for identifying a child molester as an incest offender or as a ‘stranger’ offender. We examine research findings associated with previous attempts to subcategorize child molesters as well as the literature on modus operandi. From this, we conclude that current attempts to subcategorize child molesters are flawed. We propose that distinguishing child molesters according to new criteria – that is, whether or not they have been previously associated with their victim – should result in more productive research and provide a better guide for treatment and postdischarge supervision. In our terminology, nonaffiliative child molesters are those offenders who are truly strangers to their victims whereas affiliative child molesters are characterized by an established caregiving relationship with the child for some period prior to the offense. These men, unlike nonaffiliative offenders, engage in a protracted grooming process before offending. Finally, we outline research, treatment, and risk-management strategies relevant to each of our subcategories.     

Sexual fantasy in paedophile offenders: Can any model explain satisfactorily new findings from a study of Internet and contact sexual offenders?

Purpose. There is widespread acceptance that sexual fantasy plays a role in sexual offences but little clarity as the nature of this relationship. This paper seeks to understand better the role of fantasy in offending behaviour through the study of sexual fantasy in Internet child pornography offenders when compared with contact offenders. Differences in the patterns of sexual fantasy associated with the different offender types are explored in order to understand how fantasy content is associated with contact offences with children and desisting from such direct acting out. Methods. Participants were all convicted of child sexual offences and recruited with the help of the probation and prison services. Out of these, 16 were Internet‐only offenders, 25 were contact offenders with no history of Internet offending and 10 were offenders with a mixed contact and Internet offending history. A variety of self‐completion questionnaires including fantasy were completed on an individual basis together with a detailed interview. Results. The most common sexual fantasies were typical adult‐male heterosexual fantasies though a variety of child‐oriented and other fantasies were also common. Contact offenders reported fewer girl‐oriented sexual fantasies although the groups did not differ in terms of terms of boy‐oriented fantasies. There was evidence that confrontational fantasies were commoner among contact offenders than Internet offenders. There are relationships between early sexual experiences and fantasy but peer sexual contacts seemed to be important rather than sexual abuse. Conclusion. Generally, the contact offenders seem to have less sexual fantasy pertinent to their offending than did Internet offenders. Fantasy deficit may be involved in contact offending against children.     

The impact of pre-treatment responsivity and treatment participation on violent recidivism in a violent offender sample

This study assessed whether pre-treatment responsivity (psychopathy, motivation to attend treatment, denial and minimisation of offending behaviour, and feelings of guilt or shame) predicted violent recidivism and/or moderated the effectiveness of a violence intervention programme. Participants were 114 male violent offenders who were referred to a structured violent offender group treatment programme; 84 offenders commenced the programme. Results showed that treatment completion did not have a significant main effect on recidivism but that psychopathy scores moderated the effects of treatment. Offenders with high scores on the Psychopathy Checklist: Screening Version (PCL:SV) who were rated as having good engagement with treatment, or who completed treatment, had similar violent recidivism rates compared to offenders with low PCL:SV scores. In contrast, offenders with high PCL:SV scores who dropped out of treatment or were poorly engaged had significantly higher rates of violent recidivism. These findings indicate that treatment effectiveness could be enhanced, and greater reductions in recidivism achieved, if programmes find ways to engage and maintain psychopathic offenders in treatment.     

Examining the Criminal History and Future Offending of Child Pornography Offenders: An Extended Prospective Follow-up Study

We examined police occurrence and criminal records data for a sample of 201 registered male child pornography offenders originally reported by Seto and Eke (Sex Abus J Res Treat 17:201–210, 2005), extending the average follow-up time for this sample to 5.9 years. In addition, we obtained the same data for another 340 offenders, increasing our full sample to 541 men, with a total average follow-up of 4.1 years. In the extended follow-up of the original sample, 34% of offenders had new charges for any type of reoffense, with 6% charged with a contact sexual offense against a child and an additional 3% charged with historical contact sex offenses (i.e., previously undetected offenses). For the full sample, there was a 32% any recidivism rate; 4% of offenders were charged with new contact sex offences, an additional 2% of offenders were charged with historical contact sex offenses and 7% of offenders were charged with a new child pornography offense. Predictors of new violent (including sexual contact) offending were prior offense history, including violent history, and younger offender age. Approximately a quarter of the sample was sanctioned for a failure on conditional release; in half of these failures, the offenders were in contact with children or used the internet, often to access pornography again.     

Cross-Validation and Extension of the Violence Risk Appraisal Guide for Child Molesters and Rapists

A cross-validation of the Violence Risk Appraisal Guide was performed on a sample of 159 child molesters and rapists followed for an average of 10 years at risk The performance of the instrument was also examined on a 10-yr followup of 288 sex offenders that included both those in the original construction sample for the VRAG and the validation sample. The instrument performed as well as it had in construction for predicting violent recidivism in both the cross-validation and extended followup samples, and moderately well in the prediction of sexual recidivism. Survival analyses showed that child molesters exhibited higher risk of sexual recidivism than rapists or offenders against both children and adults, whereas the opposite was true for violent recidivism. As predicted, psychopathy and phallometrically determined sexual deviance exhibited a multiplicative interaction effect on sexual recidivism. Proportional hazards event history analyses supported the use of the VRAG for the prediction of violent recidivism among sex offenders.     

Animal cruelty and firesetting as behavioral markers of fearlessness and disinhibition: putting two-thirds of Macdonald’s triad to work

The purpose of this study was to determine whether animal cruelty and firesetting can serve as markers of fearlessness and disinhibition, respectively. File data gathered on 496 male sex offenders were analyzed in an effort to test two hypotheses, a countervailing hypothesis and a narrowness hypothesis. Results pertaining to the countervailing hypothesis revealed that animal cruelty correlated significantly better with fearlessness than with disinhibition and firesetting correlated significantly better with disinhibition than with fearlessness. A multiple regression analysis controlling for age at time of discharge, participant race, and offender category (pure rapist and pure child molester) also confirmed this hypothesis. Corroborating the narrowness hypothesis, animal cruelty and firesetting failed to predict violent offending after controlling for fearlessness and disinhibition, respectively. These results suggest that animal cruelty may serve as a marker for fearlessness and callous–unemotional traits, whereas firesetting may serve as a marker for disinhibition and low self-control.     

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.     

Predictors of sex offender treatment dropout: psychopathy,sex offender risk,and responsivity implications

Abstract

We examined sex offender treatment dropout predictors, in particular, the relationship of psychopathy and sex offender risk to treatment dropout in a sample of 154 federally incarcerated sex offenders treated in a high intensity sex offender treatment program. Demographic, criminal history, mental health and treatment-related data as well as data on risk assessment measures including the Static 99, Violence Risk Scale – Sexual Offender version (VRS-SO), and Psychopathy Checklist – Revised (PCL-R) were collected. Logistic regression and discriminant function analyses were used to identify predictors that made significant and unique contributions to dropout among all the variables under study. The Emotional facet of Factor 1 of the PCL-R and never being married were found to be the most salient predictors of treatment dropout and correctly identified about 70% of the cases. The implications of the findings for managing treatment dropout and for the treatment of psychopathic offenders are discussed.     

Sexual coping,general coping and cognitive distortions in incarcerated rapists and child molesters

Abstract

Sexual coping, general coping and cognitive distortions were investigated in 25 rapists, 36 child molesters and 25 violent offenders. Rapists did not report more support for rape-supportive distortions than the violent offender comparison group. Child molesters scored higher than the other groups on the measure of molestation-supportive distortions, although mean scores were at the low end of the scale. Consistent with previous research, all offender groups reported ineffective coping styles and child molesters reported using more emotion-oriented coping than the non-sexual offenders. Child molesters but not rapists scored higher than violent offenders on deviant aspects of sexual coping, although mean scores were at the low end of the sub-scales. Evaluation of these comparisons was aided by effect sizes. The effect sizes reveal that there may indeed be differences between rapists and the comparison group with respect to cognitive distortions and sexual coping. Modest correlations were found between deviant sexual coping and cognitive distortions. The findings are interpreted in terms of etiological development and the sexual offence process.     

Psychopathy versus psychopathies in classifying criminal offenders

Purpose. Psychopathy has been shown to be related to the onset, frequency, and course of antisocial behaviour in criminal offenders. The purpose of the present study was to use cluster analysis to explore the existence of subtypes of criminal offenders in male inmates, based on the two empirically validated dimensions of psychopathy and several other dimensions previously proposed for differentiating offender groups. Methods. Two hundred male inmates participated in the study. Scores on the two dimensions of the Psychopathy Checklist–Revised ( Hare, 1991 ), the Interpersonal Measure of Psychopathy ( Kosson, Steuerwald, Forth, & Kirkhart, 1997 ), DSM‐IV diagnoses for alcohol and drug abuse/dependence, and anxiety were standardized and were included in two different types of cluster analyses. Both Ward's hierarchical method and K‐means non‐hierarchical method revealed the presence of four subtypes of criminal offenders in the sample. The four‐cluster solution was replicated when the sample was split in half and identical cluster analyses were performed on the two subsamples. Results. Two types of cluster analyses identified four subtypes of criminal offenders in two samples of jail inmates. Two of the clusters resembled primary and secondary psychopaths described in the literature, the third group exhibited some antisocial and psychopathic features, and the fourth group was non‐psychopathic. Conclusions. Findings suggest that considering the individual contributions of the two dimensions of psychopathy in lieu of the construct as a whole may prove useful in identifying relatively homogeneous groups of criminal offenders.     

Deceptive behaviour and instrumental violence among psychopathic and non-psychopathic violent forensic psychiatric patients

Deceptive behaviour and instrumental violence are well-known psychopathic features and as such play important roles in the assessment of psychopathy. This study examined first, the nature of the violence committed by offenders that have been admitted to forensic psychiatric care and whether scores on the Psychopathy Checklist: Screening Version (PCL:SV), Part 1, were associated with the instrumentality of violence. Second, we examined the proneness of offenders to re-frame the instrumentality in their past violent crimes, and whether this was associated with scores on the PCL:SV. The results show that the PCL:SV, Part 1 (interpersonal/affective features), was positively related to the officially coded instrumentality of the violent crimes. As expected, this association disappeared when the instrumentality was self-reported. However, the majority of the patients tended to exaggerate the reactivity of their violent crimes when it was self-reported, indicating that most offenders, independently of level of psychopathy, used deception when questioned about the characteristics of their past violent crimes. The reasons for, and implications of, the use of deception are discussed.     

Sexual fantasies and sensation seeking among psychopathic sexual offenders

Abstract

This study investigated the relationship between psychopathy, sensation seeking behavior and sexual fantasies in a sample of 199 participants from a maximum security forensic hospital. Psychopathy, measured by the Psychopathy Checklist – Revised (PCL-R), and several sensation seeking and sexual fantasy measures were utilized. Results indicated that, in agreement with previous research, sexually deviant psychopaths are more likely to offend against adults than children. Likewise, psychopaths showed some tendency to score significantly higher on sexual sensation seeking measures than nonpsychopathic sexual offenders. Furthermore, a relationship between psychopathy and overall sexual fantasies existed but there were not specific patterns among psychopaths and nonpsychopaths with regard to specific categories of sexual fantasies.     

Attachment styles and violence in child molesters

Abstract

It has been suggested that sexual offenders lack the capacity to engage in or to maintain intimate relationships and that their attachment styles are insecure. The present study tested some of the implications of this theory with a group of incest offenders, nonfamilial child molesters, nonsex offenders, and nonoffenders recruited from the local community. Subjects completed a self-report questionnaire detailing their characteristic relationship style, and the level of violence employed by all sexual offenders was obtained from institutional files. Nonfamilial child molesters were five times more likely to report a fearful avoidant relationship style than a secure style compared to the community group. When they rated the degree to which they considered themselves to be fearful avoidant, the ratings of the nonfamilial child molesters were significantly higher than the ratings of community subjects and incest offenders. Incest offenders did not differ from community controls or from nonsex offender controls. Of the pooled group of child molesters, dismissively avoidant offenders employed higher levels of aggression in their offences than did secure or fearful avoidant offenders. These results are discussed in the light of current theory, and suggestions for future research and treatment initiatives are offered.     

An assessment for attitudes consistent with sexual offending for use with offenders with intellectual disabilities

Background . Over the past 10 years, the focus of assessment and treatment for sex offenders has changed from the assessment of skills and deviant sexual preferences to the assessment and treatment of cognitions that might be considered to encourage or justify inappropriate sexual behaviour. There have been a few assessment measures of deviant sexual cognitions developed for adults in mainstream sex offender populations but none in less able populations. The present study describes an assessment questionnaire consisting of 7 scales for cognitions associated with rape, voyeurism, exhibitionism, dating abuse, stalking, homosexual assault and offences against children, designed to be used by sex offenders with intellectual disabilities. Method . Four groups of subjects were employed in this study – sex offenders, non‐sexual offenders, non‐offenders all with mild intellectual disabilities or borderline intelligence and a further group of normal men. All subjects completed the questionnaire and 86 subjects provided reliability data. Results . Each item was subjected to 3 tests of reliability. Retained items were required to achieve an item‐to‐total correlation of at least 0.4. Of the 7 scales, 5 achieved an internal consistency coefficient of 0.8 or greater. All scales successfully discriminated between groups even when the normal controls were eliminated because their scores were so low. Conclusions . It is possible to develop scales to assess cognitions related to types of offences which discriminate between sex offenders and other groups with intellectual disabilities. The final scales have robust statistical properties and can be used for clinical and research purposes. Some caution was noted in the use of attitudinal assessments for sex offenders.     

Psychopathy and deception detection using indirect measures

Purpose. The goal of the current study was to examine psychopathy and indirect measures of deception detection. Methods. Undergraduate students (N=444) viewed video clips of adult male offenders telling true and false stories about crimes. For each story, participants rated indirect measures of deception (thinking hard, nervousness, emotional arousal, and attempting to control behaviour) and credibility. Participants also chose the story they believed to be true and rated the confidence in their decision. Offenders were rated on the psychopathy checklist – revised. Results. Consistent with past research, deception detection accuracy was at chance level and unrelated to confidence. Ratings on indirect measures by undergraduates did not distinguish true and false statements in offenders. Psychopathic offenders were less successful at deception than non‐psychopathic offenders. Psychopathic traits were associated with lower perceived credibility during deception and ratings of thinking harder while lying. Conclusions. The results suggest that indirect measures of deception detection may be less useful in offender samples. Further, the findings are consistent with the general inability of psychopathic offenders to demonstrate superior deception skills in empirical studies. Indirect measures of deception uniquely related to psychopathic traits offer new insight into the relationship between psychopathy and deception.     

Crossover and stability of victim type in child molesters

Purpose. This study examined the degree to which child sex offenders demonstrated crossover in victim choice, as defined by age, gender, and relationship to the offender. It also aimed to explore the direction of the shift in victim type with repeated offending within each of the three domains and to identify variables predictive of crossover behaviour. Method. The sample comprised 128 adult male child sexual offenders. All had offended against multiple victims and were attending a community‐based assessment and treatment service for sexual offenders at the time of data collection. Variables were gathered, coded, and de‐identified from a manual search through clinical casenotes, from client assessment reports as well as from supplementary information consisting of sentencing remarks or other professional reports. Results. More than half of the sample (63.3%, N = 81) demonstrated crossover in victim type across at least one domain. Crossover was 48.0% (N = 59) in the age domain, 22.0% (N = 28) in the gender domain, and 25.8% (N = 33) in the relationship to victim domain. Crossover offending was associated with number of victims but unrelated to frequency of offending or to recidivism risk as assessed by a standard risk assessment instrument. Transitional matrices showed general stability in victim type across offences within the gender and relationship domains, but lower stability within the age domain. Conclusions. Crossover offending behaviour was found to be frequent in the age domain, but the high frequency of crossover in this domain may be artifactual. Crossover offending was less frequent in the gender and relationship domains, but should be taken into account in risk assessment. Victim type shows stability across multiple offences in the gender and relationship to victim domains. Analysis of victim type across multiple offences should be replicated under conditions where disclosure of offending is maximized.     

The violent female perpetrator and her victim

The aim of the present study was to examine the relationship between violent female offenders and their victims as well as the putative differences in the motives and specific psychological factors among three groups of female offenders: women who have victimised someone closely related to them, those who have victimised an acquaintance and lastly women who have victimised a stranger. More than half (N=61) of all violent female offenders hospitalised or incarcerated in Finland during the year of study were interviewed and assessed by Structured Clinical Interview II for DSM-IV (SCID-II) and Hare's Psychopathy Checklist-Revised (PCL-R). In 34% of the cases the victims were persons close to the offender, in 41% the victims were acquaintances and in 25% strangers. The victims in homicide offences were more often both male and closer to the perpetrator than in assault offences. Although motives were related to interpersonal problems, self-defence and long-term physical or psychological abuse were reported by only a few women, even for the small proportion of women whose victims were intimate partners. The most frequent reason for offences stemmed from confrontational situations in connection with alcohol use. Women who victimised acquaintances and strangers were also more likely to have a history of criminality and substance abuse than women who victimised those in close personal relationships. The latter were also more likely to have an antisocial personality disorder (PD) and psychopathic characteristics. There were, however, no significant differences found between those who had experienced physical or psychological abuse in childhood or adulthood and those who had no adverse experiences. These findings suggest that the violent behaviour by females leads more often to the death of the victim, when the victim is closely related to the perpetrator. The commonly-held view that violent female offending occurs primarily as a consequence of precipitation by the victim was not supported.     

The role of cognitive distortions in paedophilic offending: Internet and contact offenders compared

Abstract

Cognitive distortions are held to contribute to sexual offending against children in a number of theoretical explanations of such crimes. However, not only is there little or no direct evidence in support of the centrality of cognitive distortions in offending but recent research has questioned whether the concept has explanatory power. Cognitive distortions are variously seen as necessary for the offender to offend against children, as post-offending justifications for the offence, or as reflecting distorted patterns in the offender's upbringing. This paper explores the role of cognitive distortions in sex offending by comparing the distortions of contact sex offenders against children with Internet child pornography offenders without contact offences against children. A new cognitive distortions questionnaire was developed which was suitable for administration to Internet offenders who had no contact offences against children as well as being suitable for contact offenders. It was found that some cognitive distortions are frequently agreed with by sex offenders against children whereas others were seldom or never agreed with. Little support was found for earlier typological approaches to the cognitive schema of sex offenders against children. Contrary to the expectation that contact offenders would have more cognitive distortions, it was found that Internet offenders had more cognitive distortions that children are sexual beings. Furthermore, there were no differences in cognitive distortions justifying the offence. However, offenders with a previous history of offending were more likely to admit to cognitive distortions which justify their offending. It is accepted that cognitive distortions are readily recognized in interviews with sex offenders against children. Nevertheless, it is argued that there is a need for new research to stimulate a new understanding of the nature and role of cognitive distortions in sex offending.
