The Viewing Reaction Time as a Diagnostic Tool of Pedohebephilia in the Dunkelfeld

Diagnosing pedohebephilia is fraught with obstacles given the tabooed nature of this sexual preference. The viewing reaction time effect (VRT) provides a non-intrusive indirect measure of sexual interest in minors. In forensic populations, the ability of the difference between the latencies while viewing child and adult sexual stimuli (VRT index) to discern child sexual offenders from a range of control groups has been ascertained meta-analytically. Given that the effect has been studied almost exclusively in forensic samples, its dependence or independence on prior overt (deviant) sexual behavior remains unclear. The present study sought to examine the relationship of prior sexual and non-sexual behaviors with the VRT in a sample of 282 self-referring, help-seeking men with and without pedohebephilia with and without a history of prior child sexual offenses (CSO) or a use of child sexual abuse materials (CSAM) recruited outside a forensic context. We found that (1) the clinical diagnosis of pedohebephilia but not prior CSO or CSAM showed a significant association with the VRT index; (2) the discriminatory ability of the VRT index did not differ significantly between samples with and without a history of prior overt sexual behavior with children; (3) the VRT index correlated positively with a behavioral marker of pedohebephilia in a subsample of individuals with prior judicially detected or undetected overt sexual behavior with children; and (4) in the same subsample, the VRT index correlated positively with markers of sexual interests in minors or hypersexuality but not of antisociality. Equivalence testing failed to refute a potential effect of prior sexual behavior on the VRT index. Our study showed that the VRT may provide an unintrusive diagnostic tool for pedohebephilia. The effect of prior overt sexual behavior with children needs further examination.

A Review of Childhood Sexual Abuse Perpetration Prevention Programs

PURPOSE OF REVIEW

The present review examines existing childhood sexual abuse prevention programs that are focused on providing services to individuals who are at risk of perpetration. We describe several perpetrator-oriented prevention programs with evaluation data as well as avenues for future development and research.

RECENT FINDINGS

Perpetration prevention programs can be divided into anonymous and non-anonymous programs. Anonymous programs include those that provide support via helplines and those that provide self-guided digital interventions. Non-anonymous programs provide traditional psychotherapy. There are several prevention programs with limited evaluation data, but no research to date has aggregated these findings and provided a comprehensive assessment of perpetration prevention. There is insufficient evidence to determine whether perpetration prevention programs are effective. More rigorous evaluations of secondary prevention programs are needed. Despite this, early data suggests that perpetration prevention programs are promising.

Pedophile, Child Lover, or Minor-Attracted Person? Attitudes Toward Labels Among People Who are Sexually Attracted to Children

The primary label for people who are sexually attracted to children ("pedophile") is conflated with sexual offending behavior and tainted with stigma. In the present pre-registered mixed-method study, we therefore investigated attitudes and preferences regarding "pedophile/hebephile" and other labels among 286 people who report a stronger or equally strong sexual attraction to prepubescent and pubescent children than to adults. Overall, quantitative data showed acceptance of "pedophile/hebephile" as well as a range of alternative labels in a personal (Labeling Oneself) and a professional context (Being Labeled by Others). "Minor-attracted person" and "pedophile/hebephile" received generally higher support than other terms and appeared to be least divisive across three major online fora. Qualitative data revealed four themes: "Contested self-labels," "Person-first language and pathologizing sexuality/identity," "Stigma and shame," and "Reclaiming the pedophile label." Our results allow deeper insight into reasons for adopting certain labels over others, as well as difficulties of finding a non-stigmatizing label. We discuss limitations of the study and practical implications for clinical and research contexts.

Romantic and Sexual Relationships with Adult Partners Among Pedohebephilic Men

This study examined reasons for romantic and sexual relationships with adult partners among men with pedohebephilic preferences (N = 125). We also explored whether age sexual orientation impacted reasons for engaging in sex with adult partners. Pedohebephilic men endorsed both non-sexual and sexual reasons for engaging in adult-partnered relationships. The top reasons for sexual relationships with adult partners were pleasure, love and commitment, physical desirability, experience seeking, and practicality. The top reasons for romantic relationships with adult partners were to gain companionship, love toward romantic partner, to escape loneliness, to engage in sexual activities, and it seemed natural. The exclusivity of attraction to children was found to be significantly related to some of the factors. These findings support differential reasons for pedophilic men engaging in adult-partnered relationships. Professionals should seek to understand the nature of their clients' relationships and age sexual orientation to determine whether such factors are relevant. Professionals can then support clients in their search for meaningful relationships.

A map of desire: multidimensional scaling of men's sexual interest in male and female children and adults

BACKGROUND

Men sexually interested in children of a specific combination of maturity and sex tend to show some lesser interest in other categories of persons. Patterns of men's sexual interest across erotic targets' categories of maturity and sex have both clinical and basic scientific implications.

METHOD

We examined the structure of men's sexual interest in adult, pubescent, and prepubescent males and females using multidimensional scaling (MDS) across four datasets, using three large samples and three indicators of sexual interest: phallometric response to erotic stimuli, sexual offense history, and self-reported sexual attraction. The samples were highly enriched for men sexually interested in children and men accused of sexual offenses.

RESULTS

Results supported a two-dimensional MDS solution, with one dimension representing erotic targets' biological sex and the other dimension representing their sexual maturity. The dimension of sexual maturity placed adults and prepubescent children on opposite ends, and pubescent children intermediate. Differences between men's sexual interest in adults and prepubescent children of the same sex were similar in magnitude to the differences between their sexual interest in adult men and women. Sexual interest in adult men was no more associated with sexual interest in boys than sexual interest in adult women was associated with sexual interest in girls.

CONCLUSIONS

Erotic targets' sexual maturity and biological sex play important roles in men's preferences, which are predictive of sexual offending. The magnitude of men's preferences for prepubescent children v. adults of their preferred sex is large.

Meta-Analyses of Fraternal and Sororal Birth Order Effects in Homosexual Pedophiles, Hebephiles, and Teleiophiles

This study investigated the relations between numbers of older brothers, numbers of older sisters, and the odds of homosexuality in later-born males, including males who are most attracted sexually to prepubescent or early pubescent children (pedohebephiles) and males who are most attracted sexually to adults (teleiophiles). The authors meta-analyzed data from 24 samples of homosexual and heterosexual men, originally reported in 18 studies, and totaling 18,213 subjects. The results confirmed that older brothers increase the odds of same-sex preference in pedohebephiles as they do in teleiophiles. They also replicated the recent finding that older sisters have a similar but weaker statistical association with the odds of homosexuality. These findings have two theoretical implications. First, the findings for older brothers and older sisters indicate some commonality in the factors that influence sexual preference in teleiophiles and those that influence sexual preference in pedohebephiles. Second, the finding for older sisters confirms a prediction stemming from the hypothesis that male fetuses stimulate maternal antibodies that increase the odds of homosexuality in later-born males. Such immunization could result from miscarried as well as full-term fetuses, and number of older sisters should correlate with number of male fetuses miscarried before gestation of the subject.

Independent Component Analysis of Resting-State Functional Magnetic Resonance Imaging in Pedophiles

INTRODUCTION

Neuroimaging and other studies have changed the common view that pedophilia is a result of childhood sexual abuse and instead is a neurologic phenomenon with prenatal origins. Previous research has identified differences in the structural connectivity of the brain in pedophilia.

AIM

To identify analogous differences in functional connectivity.

METHODS

Functional magnetic resonance images were recorded from three groups of participants while they were at rest: pedophilic men with a history of sexual offenses against children (n = 37) and two control groups: non-pedophilic men who committed non-sexual offenses (n = 28) and non-pedophilic men with no criminal history (n = 39).

MAIN OUTCOME MEASURE

Functional magnetic resonance imaging data were subjected to independent component analysis to identify known functional networks of the brain, and groups were compared to identify differences in connectivity with those networks (or "components").

RESULTS

The pedophilic group demonstrated wide-ranging increases in functional connectivity with the default mode network compared with controls and regional differences (increases and decreases) with the frontoparietal network. Of these brain regions (total = 23), 20 have been identified by meta-analytic studies to respond to sexually relevant stimuli. Conversely, of the brain areas known to be those that respond to sexual stimuli, nearly all emerged in the present data as significantly different in pedophiles.

CONCLUSION

This study confirms the presence of significant differences in the functional connectivity of the brain in pedophilia consistent with previously reported differences in structural connectivity. The connectivity differences detected here and elsewhere are opposite in direction from those associated with anti-sociality, arguing against anti-sociality and for pedophilia as the source of the neuroanatomic differences detected.

Evidence of Construct Validity in the Assessment of Hebephilia

Hebephilia refers to a persistent intense sexual interest in pubescent children. Although not as widely studied as pedophilia, studies of hebephilia have indicated convergence in self-report and sexual arousal. The present study expanded on previous work by examining convergent and divergent validity across indicators of hebephilia that included self-report, sexual behavior, and sexual arousal in a sample of 2238 men who had sexually offended. We included men who denied such interest and specifically examined the overlap between hebephilia and pedophilia and examined pedohebephilia (i.e., sexual interests in both prepubescent and pubescent children). Results indicated that there was considerable convergence across indicators of hebephilia. The results suggested poor divergent validity between hebephilia and pedophilia, as there was substantial overlap between the two constructs across analyses. Finally, a distinct pattern of sexual arousal was found in offenders with pedohebephilia. The results of the present study were discussed with a focus on implications for the assessment of sexual interest in children and the conceptualization of pedohebephilia.

Stability of Self-Reported Arousal to Sexual Fantasies Involving Children in a Clinical Sample of Pedophiles and Hebephiles

In forensic research, there is a controversial discussion concerning the changeability or stability of pedophilia. Seto (2012) conceptualized pedophilia as a sexual age orientation characterized by an early onset, correlations with sexual and romantic behavior, and stability over time. However, empirical data are sparse and are mostly based on samples of detected offenders. The present study examined self-reported arousal to sexual fantasies involving children in a clinical sample of pedo-/hebephiles. In Study 1, retrospective self-reports on the age of onset and duration of sexual interest in minors were examined. In Study 2, the stability and variability of self-reported arousal to sexual fantasies involving children were evaluated prospectively. Non-prosecuted self-identifying pedo-/hebephilic men seeking professional help were recruited within the Berlin Prevention Project Dunkelfeld. Between 2005 and 2013, 494 participants completed the intake assessment. Self-reported data were collected via questionnaire focusing on sexual arousal to fantasies during masturbation involving prepubescent and/or early pubescent minors. Subsequent assessments of sexual arousal were obtained for 121 of the participants. The average time between the first and last assessment was approximately 29 months. Spearman's correlation coefficients examined the between-group rank-order and Wilcoxon signed-rank tests examined the within-individual mean-level stability. The majority of subjects reported an early onset of their pedo-/hebephilic sexual arousal. The rank-order stability was medium to high. Over the investigated period, the majority of subjects showed no or only minimal decrease or increase of self-reported sexual arousal. These results suggested that sexual arousal to fantasies involving prepubescent and/or early pubescent children is stable. Furthermore, the results support the conceptualization of pedo-/hebephilia as a sexual age orientation in men.
