Phallometric Nonresponding in Sexual Offenders

Factors related to phallometric nonresponding in sexual offenders were investigated. Scores on the Hare Psychopathy Checklist—Revised, the Crowne–Marlowe Social Desirability Scale, the Balanced Inventory of Desirable Responding, and the Multi-Phasic Sex Inventory were used as measures of psychological factors which may influence the level of responding obtained during presentations of audio and visual sexual stimuli. Phallometric measures employed were age/gender and female violence assessments. Significant differences were obtained between responders and nonresponders on several measures. Specifically, low responders to the female violence assessment had significantly higher scores on the Crowne–Marlowe Social Desirability Scale and the Impression Management subscale of the Balanced Inventory of Desirable Responding scale. Of special interest was the finding that approximately 75% of the participants failed to respond above 20% of full erection to either of the assessment methods.     

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.     

Phallometric Assessments Designed to Detect Arousal to Children: The Responses of Rapists and Child Molesters

The phallometric responses of child molesters and rapists were assessed using two assessments of sexual arousal to children. Groups responded to both audiotaped depictions of sexual activity with children and to a set of slides of nude adults and children. Analyses revealed that the audiotaped child sexual violence assessment was as effective as the slide assessment in discriminating child molesters from rapists. It was also found that rapists displayed some degree of deviant response to both stimulus sets.     

Identifying Schemas in Child Molesters,Rapists, and Violent Offenders

One focus of research concerning offending behavior has been the concept of the cognitive distortion, although the importance of the need for research into the underlying cognitive structures in offenders has been highlighted. This study examined schemas in child molesters, rapists, and violent offenders, predicting content differences in the offence-related schemas between these groups. In accordance with previous research, the prevalence of a “suspiciousness/hostility to women” schema in rapists was predicted. Twelve rapists, twelve child molesters, and twelve violent offenders incarcerated in a male maximum-security prison completed “Life Maps” (autobiographies) and the My Life questionnaire (R. E. Mann & C. R. Hollin, 2001), both designed to indicate the presence of schemas. A content analysis template containing nine schemas was constructed and applied to the Life Map data. Results showed a significant difference in the prevalence of schema type between the three groups. There was a prevalence of a “hostility/distrust of women” schema in the rapists. Analysis of the My Life questionnaire revealed a difference between violent offenders and rapists only. This study highlights the need for further research into schemas with sexual and violent offenders.     

Prediction of Recidivism in Extrafamilial Child Molesters Based on Court-Related Assessments

One hundred ninety-two convicted extrafamilial child molesters were followed for an average of 7.8 years after their conviction. The percentage of men who had committed a sexual, a violent, or any criminal offense by the 12th year was 15.1, 20.3, and 41.6, respectively. The sexual recidivists, compared with the nonrecidivists, demonstrated more problems with alcohol and showed greater sexual arousal to assaultive stimuli involving children than to mutually consenting stimuli with children. The violent recidivists, compared with the nonrecidivists, were more likely to have a history of violence in the families in which they were raised and were rated significantly more psychopathic on the Psychopathy Checklist—Revised (PCL-R). They also showed more sexual arousal to stimuli depicting mutually consenting sexual interactions with children than to adult stimuli. In terms of any criminal recidivism, recidivists were younger, had completed fewer years of school, and were raised in psychologically more harmful family environments compared with nonrecidivists. They also reported that, before 16 years of age, they were more likely to have been physically abused and were more likely to have been removed from their homes compared to those that did not recidivate. In addition, recidivists demonstrated more general hostility on the Buss–Durkee Hostility Inventory and were rated significantly more psychopathic on the PCL-R. The phallometric assessments revealed, that the criminal recidivists, compared to the nonrecidivists, showed more sexual arousal to stimuli depicting coercive sexual activity with children than consenting sexual activities with children. In addition, they showed more sexual arousal to scenes depicting adult rape then adult mutually consenting sex. Finally, the rcidivists also had more charges or convictions for violence and any criminal acts. The small number of significant differences between recidivists and nonrecidivists in the sexual and violent categories precluded an attempt to determine which combination of factors meaningfully predicted reoffending. However, for criminal recidivism, a stepwise discriminant function analysis to assess the combination of factors that most successfully distinguished between groups in terms of criminal recidivism was significant, with subjects' age, total number of criminal convictions, and pedophile assault index being retained for optimal prediction. The procedure correctly classified 70.6% of the original group, 82.8% of the nonrecidivists, and 52.6% of the recidivists. PCL-R Total Score alone was equally successful in a similar discriminant function.     

Visual Reaction Time and Plethysmography as Measures of Sexual Interest in Child Molesters

It is important to determine the sexual interests of those accused of child molestation. Visual reaction time and plethysmography are two means of measuring sexual interest with some objectivity, but there has been no direct comparison of these methodologies. The reliability and validity of visual reaction time and plethysmography were evaluated in groups of individuals with sexual interest in children of various ages and genders. Results showed that both methods of assessment had a high reliability and validity. Visual reaction time has the added advantages that it can be used without nude slides and is a briefer assessment.     

Childhood Attachments,Sexual Abuse,and Their Relationship to Adult Coping in Child Molesters

The present study examined the parent–child attachments, typical coping styles, and childhood sexual abuse among 30 child molesters, 24 nonsexual offenders, and 29 nonoffenders. The results indicated that all subjects reported greater security in their attachments to their mothers than to their fathers and the insecure patterns of childhood attachments were related to ineffective adult coping. The only difference observed in characteristic coping showed that child molesters were more likely to engage in emotion focused strategies. Child molesters reported having experienced high levels of childhood sexual abuse and these experiences appear to have been more distressing to them than to other subjects. The results are discussed in terms of their implications for theory and treatment.     

Trait Empathy and Criminal Versatility in Sexual Offenders

Associations between trait empathy and criminal versatility were examined in a sample of 88 incarcerated adult sexual offenders (29 extrafamilial child molesters, 26 intrafamilial child molesters, and 33 rapists). Considerable criminal versatility was observed, with 60% of the whole sample and 88% of recidivist offenders having previous convictions for nonsexual offenses. Regression analyses showed significant associations between trait empathy and nonsexual offense convictions, but not between trait empathy and sexual offense convictions. More specifically, greater involvement in violent offending (e.g., assault, robbery) was associated with lower levels of empathic concern and higher levels of fantasy. Greater involvement in miscellaneous (e.g., traffic, drug, public order) offending was associated with lower levels of empathic concern. We argue that insufficient theoretical and empirical attention has historically been given to criminal versatility among sexual offenders, especially among child molesters. In particular, we suggest that developments in empathy training for sexual offenders may benefit from distinguishing needs of criminally versatile and non-versatile sexual offenders. More knowledge about trait empathy in sexual offenders, and about situational factors that may override otherwise normal empathic responsiveness, is needed.     

The Criminal Histories and Later Offending of Child Pornography Offenders

The likelihood that child pornography offenders will later commit a contact sexual offense is unknown. In the present study, we identified a sample of 201 adult male child pornography offenders using police databases and examined their charges or convictions after the index child pornography offense(s). We also examined their criminal records to identify potential predictors of later offenses: 56% of the sample had a prior criminal record, 24% had prior contact sexual offenses, and 15% had prior child pornography offenses. One-third were concurrently charged with other crimes at the time they were charged for child pornography offenses. The average time at risk was 2.5 years; 17% of the sample offended again in some way during this time, and 4% committed a new contact sexual offense. Child pornography offenders with prior criminal records were significantly more likely to offend again in any way during the follow-up period. Child pornography offenders who had committed a prior or concurrent contact sexual offense were the most likely to offend again, either generally or sexually.     

Psychopathy, Sexual Deviance, and Recidivism Among Sex Offenders

The relationships between psychopathy, sex offender type, sexual deviance, and recidivism were examined in 156 federally incarcerated sex offenders in a 10-year follow-up study. The rapists and mixed offenders demonstrated higher psychopathy scores than did the child molesters and incest offenders (total scores and Factor 2 scores on the Psychopathy Checklist--Revised [PCL-R]; R. D. Hare, 2003). Factor 1 scores were approximately the same in all groups. The PCL-R was a weak predictor of sexual recidivism but consistently predicted nonsexual violent recidivism and general recidivism (mainly via Factor 2). Sexual deviance measured by a structured rating scheme predicted sexual recidivism. Sexual deviance, so rated, was a stronger predictor of sexual recidivism than psychopathy but the two interacted significantly suggesting that psychopathy could potentiate sexual recidivism. Although psychopathy was a strong positive predictor of general nonsexual recidivism, sexual deviance was inversely related, and no interaction was observed between psychopathy, sexual deviance, and nonsexual recidivism.     

Victim Empathy,Social Self-Esteem,and Psychopathy in Rapists

The purpose of the present study was to compare the responses of 27 incarcerated rapists and 27 incarcerated nonsexual offenders using the Rapist Empathy Measure (targeting victim specific empathy deficits) and to examine the relationship between empathy with self-esteem and psychopathy for both groups. The Social Self-Esteem Inventory was used as a measure of perceived social competence and the Psychopathy Checklist-Revised (PCL-R; Hare, 1991) was used as a measure of psychopathy. All participants completed the two self-report questionnaires on empathy and self-esteem; in addition, the rapists were required to complete an extra section of the empathy measure that assessed their empathic responses to their own victims. Demographic information and psychopathy scores were obtained by reviewing institutional files. When psychopathy scores were not available, subjects participated in a semi-structured interview and were scored on the Psychopathy Checklist-Revised by the researcher. Rapists demonstrated more empathy than the nonsexual offenders toward women in general and the same degree of empathy as the nonsexual offenders toward a woman who had been a victim of a sexual assault by another male. Of particular importance were the within-group comparisons across victim type for the rapists which revealed significant empathy deficits toward their own victim(s). Interestingly, no differences were found between the rapists and nonsexual offenders in terms of self-esteem and psychopathy, and neither self-esteem nor psychopathy significantly predicted empathy for either group. It was concluded from the present study that rapists may suppress empathy primarily toward their own victim rather than suffer from a generalized empathy deficit. It is suggested that empathy deficits in rapists might better be construed as cognitive distortions specific to their victims and should be addressed in that manner in treatment.     

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. Two 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-offcounterparts.     

Comparison of Perpetration Characteristics Between Male Juvenile and Adult Sexual Offenders: Preliminary Results

This study investigated the characteristics of the sexual abuse perpetrated by 16 juvenile (JSO) and 19 adult sexual offenders (ASO). Data were collected from a randomly selected group of males who received psychotherapy services at a community agency. The results revealed significant differences between the JSOs and the ASOs on the number of committed offenses, length of sexual relationships maintained with victims, quality of these relationships, nature of the sexual acts committed, and presence of force during abuse incidents. The results show similarities and differences in the sexual abuse characteristics perpetrated by juveniles and adults.     

Background,Offence Characteristics,and Criminal Outcomes of Aboriginal Youth Who Sexually Offend: A Closer Look at Aboriginal Youth Intervention Needs

Canada's Aboriginal peoples face a number of social and health issues. Research shows that Aboriginal youths are over-represented in the criminal justice system and youth forensic psychiatric programmes. Within the literature on sex offending youth, there appears to be no published data available to inform clinicians working with adjudicated Aboriginal youth. Therefore, the present study examines the background, offence characteristics, and criminal outcomes of Aboriginal (n = 102) and non-Aboriginal (n = 257) youths who engaged in sexual offending behaviour and were ordered to attend a sexual offender treatment programme in British Columbia between 1985 and 2004. Overall, Aboriginal youths were more likely than non-Aboriginal youths to have background histories of fetal alcohol spectrum disorders (FASD), substance abuse, childhood victimization, academic difficulties, and instability in the living environment. Both Aboriginal and non-Aboriginal youths had a tendency to target children under 12-years-old, females, and non-strangers. Aboriginal youths were more likely than non-Aboriginal youths to use substances at the time of their sexual index offence. Outcome data revealed that Aboriginal youths were more likely than their non-Aboriginal counterparts to recidivate sexually, violently, and non-violently during the 10-year follow-up period. Furthermore, the time between discharge and commission of all types of re-offences was significantly shorter for Aboriginal youths than for non-Aboriginal youths. Implications of these findings are discussed with regards to the needs of Aboriginal youth and intervention.     

Juvenile female sexual offenders: Clinical characteristics and treatment issues

The phenomenon of juvenile female sexual offending was explored through the study of 67 youths who had been referred for either community-based or residential treatment following a documented history of sexual perpetration. These youths were compared to a group of 70 juvenile male sexual offenders across three parameters: developmental and psychiatric characteristics, history of maltreatment, and sexual perpetration characteristics. Relative to the juvenile males, the histories of the studied females reflected even more extensive and pervasive childhood maltreatment, with many of the youths exposed to the modeling of interpersonal aggression by females as well as males. The majority of these juvenile female sexual offenders demonstrated repetitive patterns of sexual offending with multiple victims, suggesting psychosexual disturbances equivalent in severity to the comparison group of males. The authors discuss typological impressions of this clinical population and their special treatment needs.     

Perceived parental deviance,parent-child bonding,child abuse,and child sexual aggression

Structural equation modeling was used to test a theoretical model of the etiology of deviant sexual aggression by adolescents. The subjects were 117 juvenile male sexual offenders who had been referred from either criminal justice or social service agencies to a clinic that treated offenders. The tested theoretical model included several family factors: perceived parental deviance, child physical and sexual abuse history, and children's bonding to their parents. The model as a whole fit the data well. Results indicated that physical abuse by the father and sexual abuse by males increased sexual aggression by adolescents. Also, children's bonding to their mother was found to decrease their sexual aggression. These results are explainable from a social learning perspective and from a parent-child attachment, or social control, perspective, but the alternative perspectives of evolutionary psychology are also considered. Directions for future research are suggested.     

Investigation, science, and research partner to solve elderly woman's shocking homicide

As the investigation and prosecution of sexual homicide cases becomes increasing complex, law enforcement agencies are utilizing alternative avenues of investigative assistance. In 2004, the Oakland County, Michigan Sheriff's Office was faced with the horrific sexual assault and murder of an elderly woman. Although familiar with violent crime, this extremely violent and unusual case motivated the police to enlist the help of forensic scientists and FBI violent crime researchers to assist their investigation. This partnership led to the successful investigation and prosecution of the offender and serves as a model for law enforcement agencies willing to consider using additional available resources in order to successfully resolve unusual and extraordinarily violent sexual crimes.     

Childhood Attachment,Childhood Sexual Abuse,and Onset of Masturbation Among Adult Sexual Offenders

Written autobiographies of 48 incarcerated adult male sexual offenders (22 rapists, 13 intrafamilial child molesters, and 13 extrafamilial child molesters) were used to generate retrospective self-report measures of their childhood maternal and paternal attachment, childhood sexual abuse experiences, and onset of masturbation. Contrary to expectation, the offenders as a combined group more often reported secure than they did insecure childhood maternal and paternal attachment. There were no differences between the three offender subgroups with respect to maternal attachment; however the rapists and the intrafamilial child molesters were more likely to report insecure paternal attachment than were the extrafamilial child molesters. There were no differences between these offender subgroups in the frequency with which childhood sexual abuse was reported. However, offenders with insecure paternal attachment were more likely to report having been sexually abused than were those with secure paternal attachment. Sexually abused offenders in turn reported earlier onset of masturbation than did those who were not sexually abused. These results are consistent with contemporary attachment models linking insecure childhood attachment to childhood sexual abuse, and with traditional conditioning models linking childhood sexual abuse, early masturbation, and sexual offending.     

Therapeutic Engagement Styles of Child Sexual Offenders in a Group Treatment Program: A Grounded Theory Study

It is widely observed that child sexual offenders typically exhibit considerable reluctance to self-disclose at a level that reflects the full reality of their offending. Their successful engagement in relapse prevention-based programs is therefore problematic. This paper describes a study involving men undertaking a prototypical group treatment program, facing the challenge of revealing to others the details of their offense process. A procedure was developed to access their covert responses at the time of this encounter. From a grounded theory analysis, participants were found to employ various strategies to manage situations where self-disclosure was required. Four distinct disclosure management styles emerged: exploratory, oppositional, evasive, and placatory; the latter three of which appear unfavorable to effective engagement in treatment. As well as suggesting ways of influencing disclosure management style, analysis indicated that it might be possible to predict these different orientations during routine assessment.
