Characteristics of Female Solo and Female Co-Offenders and Male Solo Sexual Offenders Against Children.

Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

Male and Female Single-Victim Sexual Homicide Offenders: Distinguishing the Types of Weapons Used in Killing Their Victims.

Most studies have focused on male sexual homicide offenders (SHOs) without testing whether sex differences exist. Accordingly, little is known about the distinctions between male and female SHOs, particularly with respect to their use of weapons in killing their victims. This study used a sample of 3,160 single-victim sexual homicide cases (3,009 male and 151 female offenders) from the U.S. Supplementary Homicide Reports database to explore sex differences in the types of murder weapons used by offenders in killing victims over the 37-year period 1976 to 2012. Findings indicated that significantly more male SHOs used personal weapons (43%) and more female SHOs used firearms (63%) in their offense commission. In general, female offenders predominantly used weapons that were physically less demanding (e.g., firearms and edged and other weapons; 89%). Different trends in the murder weapons used by male and female SHOs from different age groups were observed. Interestingly, findings showed that the type of weapon used by SHOs was in part influenced by the victims and their characteristics.

Adverse Childhood Experiences and Criminal Extremity: New Evidence for Sexual Homicide.

Adverse childhood experiences are associated with a wide range of behavioral, health, and psychiatric deficits and have recently been used to study the development of serious offending careers. Unfortunately, this research paradigm has largely ignored forensic populations. This study utilized the adverse childhood experiences framework to examine the associations between exposure to violence, victimization, and total adverse childhood experiences on sexual homicide using a sample of 616 incarcerated adult male sexual offenders from Canada 85 of whom committed sexual homicide. Epidemiological tables of odds revealed that a gradient of adverse childhood experiences was associated with sexual homicide, but that the most significant risks were for offenders who had the most extensive abuse histories. In adjusted models, exposure to violence, victimization, and total adverse childhood experiences increased the odds of sexual homicide by 334%, 249%, and 546%, respectively. These effects intensified in models adjusted for childhood enuresis, cruelty to animals, parental abandonment, deviant sexual behaviors, poor self-image, and sexual problems to 559%, 326%, and 849%, respectively. The adverse childhood experiences framework is a systematic way to organize the criminogenic developmental sequela in sexual homicide.

Sexual Murderers: Sex Offender, Murderer, or Both?

Sexual murderers perpetrate homicide and rape/sexual abuse, but it is unclear whether they should primarily be considered homicide offenders, sexual offenders, or both. Most studies have merged together different types of non-homicidal sex offenders (NHSOs), neglecting to consider the potential differences between the nonviolent and violent sex offenders. Here, we suggest it is important to isolate those violent sex offenders who inflict severe physical injuries that could potentially lead to a lethal outcome. Therefore, the aim of the current study is to compare different measures of the criminal career on three groups of sex offenders: NHSOs, violent NHSOs, and sexual homicide offenders (SHOs) using data from 616 incarcerated male sex offenders in a Federal penitentiary in Canada. Interestingly, the group of sex offenders with the worst criminal career profile was not the SHOs, but the violent NHSOs. Violent NHSOs had the greatest number of prior convictions and the most varied and versatile criminal career. Therefore, we suggest that based on their criminal career, SHOs should be considered more as murderers than sex offenders. However, to fully answer this question, future studies should include a group of non-sexual homicide offenders.

Sex Offenders of East Asian Heritage Resemble Other Canadian Sex Offenders

Although there is considerable research on Caucasian sexual offenders, there has been much less research on sex offenders of Asian heritage. The current study compared East Asian (e.g., Chinese, Japanese, and Korean) sex offenders in British Columbia (B.C.), Canada, and other B.C. sex offenders on items and total score of Static-99R. This study included all provincially sentenced adult male sexual offenders (n = 4580) supervised in the community by B. C. Corrections (including 122 East Asian sex offenders). Sexual, violent, any crime, and any recidivism (including technical violations) data were collected with an average follow-up 4.3 years. The total scores of Static-99R were similar between East Asian sex offenders and other ethnic groups (M = 2.0 vs. M = 2.4). East Asian offenders scored significantly lower than other ethnic offenders on several items measuring general criminality (e.g., prior non-sexual violence, prior sentencing dates, and any prior sex offenses). In contrast, Asian offenders appeared to be more paraphilic (e.g., any convictions for non-contact sex offenses). Lastly, Static-99R significantly predicts sexual, violent, and criminal among sex offenders of East Asian heritage.

Factors behind support for harsher punishments for common and uncommon offenders

PurposeThe purpose of this paper is to explore individual factors predicting support for harsher punishments for relatively common and uncommon serious offenders.Design/methodology/approachIn Study 1, 120 UK participants (60 males and 60 females; mean age =37.31 SD=16.74) completed a survey exploring the extent to which they supported harsher punishments (SHP) for first time and repeat fraud, sexual and violent offenders. In Study 2, 131 participants (70 Britons and 61 Singaporeans; 69 females and 62 males; mean age=31.57; SD=10.87) completed a similar survey exploring their support for life sentence without the possibility of parole (SLSWP) for rather uncommon repeat offenders (i.e. drug traffickers, human traffickers, serious sexual offenders).FindingsStudy 1 found that right-wing authoritarianism (RWA) was an SHP predictor for first time and repeat fraud, violent and sex offenders. Study 2 found that national identity (i.e. how British or Singaporean participants felt) played a similar role to Study 1’s RWA in being a positive SLSWP predictor for repeat human traffickers and drug traffickers of both sexes, as well as male sex offenders. In contrast to the hypothesis, however, participants’ locations did not appear to play a statistically significant role.Research limitations/implicationsThis survey-based research reveals a nuanced and quite consistent picture that could benefit from the inclusion of socio-economic factors and other cross-cultural comparisons.Practical implicationsThe key message from this study is to inform the public on the role that right-wing authoritarianism and national identity play in their SHP and SLSWP.Social implicationsIt is vital to increase the legislators’ and the public awareness of the role that national identity and RWA seem to play.Originality/valueThe paper offers insight into factors behind people’s punitive attitudes towards specific crimes regardless of geo-cultural location.

Working Alliance and Psychopathy: Linkages to Treatment Outcome in a Sample of Treated Sexual Offenders.

The present study examined the working alliance, as measured by the full-length Working Alliance Inventory (WAI), and its association with psychopathy, treatment completion, and recidivism in a sample of 111 incarcerated adult male sexual offenders. The men completed the WAI 3 months into their treatment program, while psychopathy was measured via file-based ratings of the Hare's Psychopathy Checklist-Revised (PCL-R), and outcome data were collected via the Canadian Police Information Centre. The majority (85%) of high PCL-R scoring men (PCL-R 25+) successfully completed their treatment program, and by and large, the men demonstrated strong working alliances with their primary therapists. The WAI scale components showed differential associations with the structural features of psychopathy. Specifically, the Affective facet was significantly associated with weaker Bond scores, while the Lifestyle facet was associated with lower Task scores; these results were upheld after controlling for scores on the other PCL-R facets. Strength of alliance, however, was not significantly associated with any recidivism outcomes, irrespective of controls for psychopathy. Implications for the treatment of offenders with high levels of psychopathic traits are discussed in light of extant findings and unique features of the therapeutic alliance.

The use of cyproterone acetate in a forensic psychiatric cohort of male sex offenders and its associations with sexual activity and sexual functioning.

BackgroundCyproterone acetate (CPA) is a steroidal anti-androgenic medication used in the field of psychiatry for the treatment of paraphilic disorders, hypersexuality, and inappropriate sexual behaviour which may be present in patients with disorders such as mild and major neurocognitive disorders. In the forensic psychiatric population, it is prescribed for these indications especially for patients with a history of committing a sexual offence or who are at moderate to high risk of recidivism.ObjectivesTo investigate the use of CPA in a forensic psychiatric cohort of male sex offenders and its associations with sexual activity and sexual functioning.MethodsSeventy-six forensic psychiatric patients from Weskoppies Hospital in Pretoria, South Africa, participated in the study which measured their sexual functioning. A specifically designed questionnaire was used to capture relevant background information. The use of CPA was studied. The Changes in Sexual Functioning Questionnaire, Male Clinical Version (CSFQ-M-C) was used to measure sexual functioning of participants. The CSFQ-M-C scores, and those of all its subscales, of participants on CPA were compared to those not on the drug. Relevant statistical analyses were performed.ResultsThirteen out of the 76 participants were being treated with CPA (17.11%). In total, 53.85% of the participants on CPA and 65.08% not on CPA had scores indicating the presence of sexual dysfunction. The total CSFQ-M-C scores for participants on CPA (mean = 40.54; median = 42) were not statistically significantly lower than those not on the drug (mean = 41.22; median = 41). More notable is that the use of CPA in this population was associated with lower levels of desire, frequency of and pleasure from sexual activity. There was an association between having intellectual disability and being treated with CPA.ConclusionThat all the participants were being treated with psychotropic medication could account for the high percentage of sexual dysfunction in any or all areas of sexual functioning and contribute to the small difference in CSFQ-M-C scores between the two groups. Only a tentative conclusion can be made that CPA may be more effective in decreasing levels of desire, frequency and pleasure related to sexual activity than other areas of sexual functioning. The indication for the use of CPA in this population should be assessed clinically according to patient circumstances and risk assessment.

Sexual offender treatment for reducing recidivism among convicted sex offenders: a systematic review and meta‐analysis

Sexual offender treatment for reducing recidivism among convicted sex offenders: a systematic review and meta‐analysis

The Voices of Young Sexual Offenders in Norway: A Qualitative Study

Adolescents commit around 20 - 30 percent of all sexual offences and attempts have been made in the literature to distinguish between types of young sexual offenders. This study describes the understanding of nine Norwegian young male sexual offenders regarding sexual offences committed by them during adolescence, their childhood experiences and their suggestions on how to prevent juvenile sexual offending. The participants were interviewed with individual, semi-structured interviews and the rich data were analyzed with systematic text condensation. The young offenders’ understanding of mutuality in the relationship with their minor victim contributed to the sexual offence. Moreover, moral immaturity, learning difficulties or being a refugee, exposure to child pornography, impulsivity and high sexual arousal were described as having impacted on their offending. Findings suggest the need for further studies to understand the risk factors for juvenile sexual offending. Better knowledge about the legal framework of a sexual relationship and consequences of sexual abuse for both offenders and victims were highlighted to be the most important measure to prevent sexual abuse by juveniles in general.

Resolve: a community-based forensic learning disability service specialising in supporting male sex offenders – our model, approach and evidence base for effective intervention

Purpose The purpose of this paper is to examine a model of effective forensic practice with positive interventions for men with learning disabilities who have committed serious sexual offences. It outlines the theoretical and philosophical frameworks which have informed the model of care and support in a community-based setting and the evidence base for the efficacy of the approach. Design/methodology/approach This approach to a community-based forensic learning disability service is informed by systemic practice and underpinned by models of human occupation (Keilhofner, 2008) which informs occupational therapy and total attachment (Harbottle et al., 2014). This is a whole systems model for developing compassionate and participatory practice based on attachment theory and approaches to professional parenting drawn from foster care settings and prevention frameworks for adult safeguarding. It uses Klinean Thinking Environments (1999) to give practical communication to the model. Findings The attachment model which underpins both the support for staff and the framework for scaffolding the care and support provided for service users is building calm, consistent and respectful relationships. This enables workers and service users to feel accepted through the availability of support; to feel a sense of belonging and inclusion in which skills and confidence can flourish helping all to feel more effective. This is evidenced by the stability of the service user group and the staff team. Research limitations/implications The model of whole system care and support care outlined in this paper can help to provide a therapeutic environment in which men who have committed sexual offences can develop effective skills within a safe, supportive and effectively managed setting. This is on-going research but there is evidence of service users and staff in this model of practice, feeling scaffolded, able to enjoy and achieve progress and personal development. Practical implications This model appears to promote stable, sustained, supportive relationships. Placement breakdown has been minimal indicating that the disruption rate is low and therefore therapeutic interventions are likely to take place and be effective. This is a hopeful and positive approach which enables individuals to flourish in a safe environment. Social implications The social implications of this model are positive for creating a stable workforce in an industry plagued with rapid turn over of staff to the detriment of the quality of life for service users. It creates stability and confidence for the residents allowing them to begin to relax and thereafter achieve more positive relationships. Originality/value This paper examines the application of theoretical frameworks drawn from other disciplines and fuses them into a therapeutic approach to support this service user group. It is a model that can have great portability to other settings but it is its application in forensic services that is new and which is growing its evidence base for its effectiveness.

The Impact of Types and Extent of Trauma on Depressive Affect Among Male Juvenile Sexual Offenders.

High levels of depression have been found among incarcerated youth, which suggests that mental health problems are associated with delinquent behavior and are part of a constellation of risk factors that contribute to youth entering the juvenile justice system. In this project, we investigated trauma and mental health issues among male youth in residential treatment, and addressed the following questions: (a) Does childhood trauma predict current depression for male juvenile sexual offenders? (b) If so, do different types of traumas predict depressive affect better than others? and, (c) Does extent of trauma exposure predict depression? Data on incarcerated male juvenile sexual offenders were analyzed ( n = 379). Multiple regressions of various types of traumas and cumulative trauma and depression were conducted. Emotional abuse was the strongest predictor of depressive affect for this sample, and multiple exposures to trauma were the second strongest predictor.

“It must be great being a female pedophile!”: The nature of public perceptions about female teacher sex offenders

Although female sex offenders have received increased scholarly attention in recent years, and have also gained widespread media attention, minimal research has focused specifically on public perceptions of their behavior. This study explores the nature of public perceptions of a group of offenders on which the media often focus—female teachers who assault adolescent male students—by examining reader comments posted on five Huffington Post articles published from November 2010 to November 2013. Using a thematic coding methodology to analyze over 900 online comments, we found that most comments recognize a current double standard in the sentencing process for female teacher sex offenders compared to their male counterparts. Comments also rely on traditional sexual scripts and/or gender role expectations to either acknowledge or deny a victim’s presence. Contrary to existing research that examined public perceptions and found that more punitive attitudes were expressed toward male sex offenders, these results suggest that the public believes in equality in sentencing for all sex offenders, regardless of gender. These results also confirm prior studies that find that the public perceives adolescent male victims of rape by older women “lucky.”

Comparison of arousal and preference assessment outcomes for sex offenders with intellectual disabilities.

We compared outcomes of arousal and preference assessments for five adult male alleged sexual offenders with intellectual disabilities. Arousal assessments involved the use of the penile plethysmograph to measure changes in penile circumference to both deviant (males and females under the age of 18) and nondeviant (males and females over the age of 18) video clips. Paired-stimulus preference assessments were arranged to present still images from the video clips used in the arousal assessments. Results showed correspondence between the assessments for four out of the five participants. Implications are discussed for the use of preference assessment methodology as a less intrusive assessment approach for sexual offender assessments.

Relations Between Self-Reported Adverse Events in Childhood and Hypersexuality in Adult Male Sexual Offenders.

Hypersexuality, or extreme normophilic sexual urges and behaviors, is a controversial construct that was recently considered as a candidate disorder for the DSM-5 and was rejected. It was also rejected for inclusion in Section III (Conditions for Further Study). Nonetheless, it has been found to be an important predictor of recidivism among sex offenders, and it continues to be discussed widely in the literature. In the present study, we investigated the developmental roots of this construct in a sample of 529 adult male sexual offenders, who were administered the Multidimensional Assessment of Sex and Aggression. Physical, psychological, and sexual abuse experiences were estimated using several scales of early development. Psychological abuse in childhood and adolescence, especially by a father, was found to be the most prominent predictor of subsequent hypersexual thoughts and behaviors. The accumulation of abuse types, however, was also associated with a monotonic increase in the latent trait of hypersexuality. The consequences of these results for conceptualizations of the construct are discussed.

Parental and perinatal risk factors for sexual offending in men: a nationwide case-control study.

Prior studies suggest parental and perinatal risk factors are associated with later offending. It remains uncertain, however, if such risk factors are similarly related to sexual offending. We linked socio-demographic, family relations, and perinatal (obtained at birth) data from the nationwide Swedish registers from 1973 to 2009 with information on criminal convictions of cases and control subjects. Male sex offenders (n = 13 773) were matched 1:5 on birth year and county of birth in Sweden to male controls without sexual or non-sexual violent convictions. To examine risk-factor specificity for sexual offending, we also compared male violent, non-sexual offenders (n = 135 953) to controls without sexual or non-sexual violent convictions. Predictors included parental (young maternal or paternal age at son's birth, educational attainment, violent crime, psychiatric disorder, substance misuse, suicide attempt) and perinatal (number of older brothers, low Apgar score, low birth weight, being small for gestational age, congenital malformations, small head size) variables. Conditional logistic regression models found consistent patterns of statistically significant, small to moderate independent associations of parental risk factors with sons' sexual offending and non-sexual violent offending. For perinatal risk factors, patterns varied more; small for gestational age and small head size exhibited similar risk effects for both offence types whereas a higher number of older biological brothers and any congenital malformation were small, independent risk factors only for non-sexual violence. This nationwide study suggests substantial commonalities in parental and perinatal risk factors for the onset of sexual and non-sexual violent offending.

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.

Treatment Experiences of Child Sexual Offenders in Norway: A Qualitative Study

ABSTRACTThis article is an attempt at gaining a better understanding of treatment of adults who have committed sexual offenses against children. In this study we aimed to explore what people who have committed sexual offenses against children find useful in therapy. The study was approached using qualitative methodology, and information was collected through semistructured interviews. Four male child sexual offenders were recruited from the Institute of Clinical Sexology and Therapy in Oslo, Norway. The informants were interviewed with a focus on what factors they found useful in therapy. Through an explorative, thematic analysis, five main themes were found. These themes include: “Why I started going to therapy,” “Why did I do it?” “Therapy as life,” “Previous and current relationships with others,” and “I lived in a fantasy world where everything was okay.” Based on this study and other earlier studies and theories it appears that the previously mentioned themes recur as important contributory factors in the treatment of child sexual offenders.

Age Diversity Among Victims of Hebephilic Sexual Offenders.

Hebephilia refers to sexual interest in pubescent children who are beginning to show early signs of sexual development but are sexually immature. The present study examined the relationship between hebephilia and victim age choice in a sample of 2,238 adult male sexual offenders. On average, offenders were 39 years old at the time of their assessments, and approximately half (48%) were referred by probation or parole offices. Assessment data included self-report, sexual arousal measured by volumetric phallometry, and victims' ages. Results suggested that, similar to pedophilia, hebephilia had a medium sized association with a greater number of victims under age 11 and a small sized association with a greater number of victims ages 11 to 14. Unlike pedophilia, a small positive association was consistently found between hebephilia and a greater number of victims ages 15 or 16. Furthermore, a small positive association was observed between victim age polymorphism and hebephilia and pedophilia. The present results suggested that hebephilia was associated with a greater number of victims age 14 or younger and had similar victim age correlates to pedophiles.

Factors Predicting Desistance From Reoffending: A Validation Study of the SAPROF in Sexual Offenders.

The present study aims at validating the German version of the Structured Assessment of PROtective Factors (SAPROF) for violence risk in a representative sample of incarcerated adult male sexual offenders. Sexual offenders ( n = 450) were rated retrospectively with the SAPROF using the database of the Federal Evaluation Centre for Violent and Sexual Offenders (FECVSO) in the Austrian Prison System. Interrater reliability and predictive validity of the SAPROF scores concerning desistance from recidivism were calculated. Concurrent and incremental validity were tested using the combination of the SAPROF and the Sexual Violence Risk-20 (SVR-20). Interrater reliability was moderate to excellent, and predictive accuracy for various types of recidivism was rather small to moderate. There was a clear negative relationship between the SAPROF and the SVR-20 risk factors. Whereas the SAPROF revealed itself as a significant predictor for various recidivism categories, it did not add any predictive value beyond the SVR-20. Although the SAPROF itself can predict desistance from recidivism, it seems to contribute to the risk assessment in convicted sexual offenders only to a limited extent, once customary risk assessment tools have been applied. Implications for clinical use and further studies are discussed.
