Romeo & Juliet Laws: Investigating UK Public Perceptions of Young Consensual Sex and the Effects of Age Gaps and Perpetrator and Respondent Gender

Public perception of regulated sexual behavior is a crucial factor in considering policy, particularly when UK sexual consent laws could criminalize the many young people who are increasingly engaging in underage sex. In contrast, other countries have progressively implemented consent age-spans to respect sexual autonomy while simultaneously protecting young people from sexual exploitation. This study investigated UK perceptions of consensual underage sex between similar-aged adolescents, with predominant focus on age-spans, as an adaptive alternative to dropping consent age. An online experimental survey of members of the UK public (n = 336) manipulated age-gaps, perpetrator gender, and respondent gender. Supporting the hypothesis, results showed more support (i.e., reduced condemnation of the situation, perpetrator, and victim) was given for sex with age gaps of up to 2 years than those larger. Gender differences were present only for age gaps of 3 and 4 years, where harsher situation and perpetrator judgments were elicited when the perpetrator was male. To our knowledge, this is the first UK-based study investigating perceptions of similar-aged consensual underage sex, and therefore forms a baseline for future research. Results are discussed in terms of acceptability of behavior and present important evidence for policymakers to consider reviewing UK consent laws in line with international legislation.

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.

Hypothalamic volume in pedophilia with or without child sexual offense

The hypothalamus regulates sexual behavior and is simultaneously associated with aggression and violence. Consequently, this brain region is relevant in research of pedophilia and child sexual offenses (CSO). The distinction between these two phenomena is of great importance and was the object of consideration of this study. We analyzed exclusively men, including 73 pedophilic offenders who committed CSO, an equal number of people with pedophilia but without such offenses, and 133 non-pedophilic, non-offending subjects who formed the control group. All data were collected in a multicenter in vivo study and analyzed using a semi-automated segmentation algorithm for 3-Tesla magnetic resonance images. Men with pedophilia who committed CSO on average had a 47 mm3 smaller hypothalamus per side than people without committed CSO. This effect was driven by both the group of non-offending people with pedophilia and the control group. By contrast, the exploratory comparison of pedophilic persons without CSO with the control group showed no significant difference. The present study demonstrates a deviant hypothalamic structure as a neurobiological correlate of CSO in pedophiles, but not in people with pedophilia who have not committed CSO. Thus, it strengthens the argument to distinguish between sexual offending and paraphilic sexual preferences.

Understanding Pedophilia: A Theoretical Framework on the Development of Sexual Penchants

Pedophilia is a significant public health problem. Despite its cost to society, little effort has been directed toward understanding idiographic differences in the development and maintenance of pedophilia. Extant literature emphasizes biological underpinnings and predictors of re-offense. In this article, we posit that pedophilic penchants in males originate due to language, cognition, emotions, and emotion regulation. Adverse childhood experiences, such as emotional and sexual abuse, are posited as a major contributor to the etiology of pedophilia. However, not all individuals attracted to minors present with similar childhood adversities. The development of pedophilia, in the absence of such direct training (childhood adversities), is difficult to comprehend. Relational frame theory, a comprehensive account of human language and cognition, aids in deciphering the idiographic underpinnings of pedophilia. The role of maladaptive emotion regulation in maintaining pedophilia is also described. This article presents examples of how relational frames are established and activated in distressing contexts. Finally, implications for future research are discussed.

What can the eyes tell us about atypical sexual preferences as a function of sex and age? Linking eye movements with child-related chronophilias

Visual attention plays a central role in current theories of sexual information processing and is key to informing the use of eye-tracking techniques in the study of typical sexual preferences and more recently, in the study of atypical preferences such as pedophilia (prepubescent children) and hebephilia (pubescent children). The aim of this theoretical-empirical review is to connect the concepts of a visual attention-based model of sexual arousal processing with eye movements as indicators of atypical sexual interests, to substantiate the use of eye-tracking as a useful indirect measure of sexual preferences according to sex and age of the stimuli. Implications for research are discussed in terms of recognizing the value, scope and limitations of eye-tracking in the study of pedophilia and other chronophilias in males and females, and the generation of new hypotheses using this type of indirect measure of human sexual response.

Qualitative Analysis of Minor Attracted Persons' Subjective Experience: Implications for Treatment

Treatment for Minor Attracted Persons is inadequate and difficult to access. This qualitative study examined community-based MAPs' responses to narrative questions about their experiences and what they want society to understand, using an iterative thematic analysis. Notable responses from the participants included: 1) sexual attraction does not equal action; 2) minor attraction is immutable; 3) stigma leads to psychological burden; 4) therapy should aim to reduce distress, not change sexual feelings; and 5) sexual behavior can be controlled and remain within legal parameters. Further understanding of MAPs' experiences is key for developing more efficacious treatment modalities to help them live meaningful lives without endangering children.

Stigmatisation of People with Deviant Sexual Interest: A Comparative Study

Background: Pedophilia is a deviant sexual interest subject to more public stigma and punitive attitudes than others. Pedophilia has received a disproportionate amount of scholarly attention in comparison to other deviant sexual interests. To address this, the present study offers a comparison of the public stigma and punitive attitudes associated with pedophilia, fetishism, and hypersexuality. Methods: Recruited in Australia, one-hundred and twelve individuals participated in an anonymous online survey. Stigmatising and punitive attitudes toward pedophilia, fetishism, and hypersexuality were assessed via sub-scales of perceived dangerousness, deviance, intentionality, and punitive attitudes. Results: Participants held harsher punitive attitudes toward people with pedophilia and thought them to be more deviant and dangerous than people with fetishism and hypersexuality. Participants perceived hypersexuality to be more dangerous and deviant than fetishism. No consistent combination of perceived dangerousness, deviance, and intentionality predicted punitive attitudes toward all conditions. Rather, combinations of punitive attitude predictors were unique across conditions. Conclusions: This research articulates the unparalleled public stigma and punitive attitudes faced by people with pedophilia, compared to people with fetishism and hypersexuality. Findings which suggest that public stigma is stronger for hypersexuality than it is for fetishism are relatively novel, as are the observed predictors of punitive attitudes toward each condition. Knowledge produced by this study contributes to an improved conceptualisation of how the public views individuals who experience deviant sexual interests.

Validating the Screening Scale of Pedophilic Crime Scene Behavior

The Screening Scale of Pedophilic Crime Scene Behavior (SSPC) is a seven-item structured rating scale assessing pedophilic sexual arousal. In the current study, we cross-validated the scale's convergent validity using multiple measures of sexual interest in children (clinical diagnosis of pedophilia, the high fixation/low social competence type of the MTC:CM4, and phallometric assessment of sexual interests toward children) in two independent samples (USA and Canada). In both samples and in relation to all three criteria, the SSPC showed acceptable (phallometry) to excellent (clinical assessment) diagnostic accuracy. Furthermore, the SSPC showed incremental validity in relation to the Screening Scale for Pedophilic Interest and at times outperformed it in convergent validity analyses. The current study also provides psychometric information that can help users choose an appropriate SSPC cutoff score.

Lay People´s Myths Regarding Pedophilia and Child Sexual Abuse: A Systematic Review

INTRODUCTION

The term "paedophilia erotica" was first coined in 1886 by the psychiatrist Krafft-Ebing and it was considered a "psycho-sexual perversion." It was at the beginning of the twentieth century that the term "pedophilia" was adopted and it started to appear in medical dictionaries. Sexual abuse is legally defined as the engagement in sexual contact with a person below a specified age or who is incapable of giving consent. Both, pedophilia and child sexual abuse (CSA) are worldwide phenomena requiring deep scientific knowledge in order to improve prevention strategies. Individuals' misconceptions of pedophilia and CSA may legitimize sexual violence, which can influence prevention strategies and policies.

OBJECTIVES

This review aimed to summarize existing research to help answer the question: "What are laypeople´s myths regarding pedophilia and CSA?"

METHODS

This systematic review followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses to identify as many relevant articles as possible. A literature search was conducted using PubMed, Web of Science, Scopus, and EBSCOhost databases for articles published before January 2022. Sixty-one articles were included in the current review.

RESULTS

Overall, findings revealed a significant number of myths regarding pedophilia and CSA, organized into the following categories: (i) blame diffusion, (ii) denial of abusiveness, (iii) restrictive stereotypes, (iv) victim age and consequences, (v) social stigma, (vi) punitive attitudes, and (vii) treatment.

CONCLUSION

Findings suggested that laypeople's perceptions should be taken into account when devising prevention policies. Additionally, perceptions should also be a target of prevention since there is evidence of social stigma and prejudice involving individuals with pedophilia. Such phenomena can contribute to social, emotional, and cognitive problems, among said individuals as well as causing these individuals to exhibit a higher risk for abusive behavior and less help-seeking.

Androgens, brain and androgen deprivation therapy in paraphilic disorders: A narrative review

Sexual delinquency is a global problem where those with paraphilic disorders, such as paedophiles, are more likely to commit and reoffend. Androgen deprivation therapy (ADT) has been suggested as a solution. The objective of this narrative review is to present current information on its risks, benefits and limitations as a treatment for paraphilias. The importance of testosterone in sexual function, the effect of its deficiency by age or by pharmacological treatment (anti-androgens, GnRH agonists and GnRH antagonists) and the effect of testosterone replacement therapy will be reviewed. The relationship between androgens, brain, sexual behaviour and pathophysiology of paraphilic disorders will also be explored. ADT reduces sexual urges, but has adverse effects and, because its reversible nature, it does not ensure less recidivism. Likewise, the research quality of ADT drugs is limited and not enough to support their use. Child sex offenders, and not paraphilic subjects who have not committed assaults, show signs of elevated prenatal exposure to androgens and a higher methylation state of the androgen receptor gene. Sexual behaviour is regulated by subcortical (hypothalamus, brainstem and spinal cord) and cortical structures of the brain, in addition to brain circuits (dopaminergic, serotonergic). Those with paraphilic disorders show abnormalities at these levels that could relate to the risk of sexual offences. In conclusion, androgens represent a significant part of the pathophysiology of paraphilias and therefore, ADT seems promising. Nonetheless, more studies are needed to make definite conclusions about the efficacy of long-term ADT in paraphilic patients.

Media Coverage of Pedophilia and Its Impact on Help-Seeking Persons with Pedophilia in Germany—A Focus Group Study

The public stigma associated with pedophilia, the sexual attraction to prepubescent children, is tremendous. Previous research indicates that undifferentiated media coverage plays an essential role in perpetuating the public stigma by falsely equating pedophilia and child sexual abuse (CSA) and thus may stop persons suffering from a pedophilic disorder from seeking professional help. Until now, a comprehensive examination of positive as well as negative media effects on affected individuals is missing. Therefore, the present study explores if and how media coverage impacts the lives of help-seeking persons with pedophilia by conducting four qualitative focus group discussions with a clinical sample (N = 20) from the German Prevention Network “Kein Täter werden”. Present results demonstrate that media coverage of pedophilia was perceived as mostly undifferentiated, even though participants observed an increase in fact-based reporting over the years. Moreover, it seems that media coverage has strong emotional and behavioral consequences for patients (e.g., negative reporting reduced self-esteem). In sum, our results highlight that differentiated media coverage could play a key role in supporting help-seeking persons with pedophilic disorder, while the impact of undifferentiated media coverage appears to be mostly negative. Therefore, our results point to the need to reframe pedophilia using differentiated media coverage to help affected persons receive treatment efficiently and thereby prevent CSA.

Framing Perpetrators of Sexual Violence Who Participate in Circles of Support and Accountability (CoSA): An Analysis of Global Print Media Reporting

Circles of Support and Accountability (CoSA) are now part of the criminal justice landscape in various parts of the world. While CoSA have received considerable media attention, it is not yet known how they are portrayed in the media. This study addressed this gap by analyzing newspaper coverage of CoSA from across the English-speaking world. Overall, it identified that representations of those convicted of sexual violence in print media accounts of CoSA differ substantially from those identified in previous scholarship. We argue therefore that the nature of CoSA as an intervention may allow for more sympathetic and humanistic representation. The findings provide a platform from which the international CoSA community can develop strategic approaches to interacting with the media.

Primary Health Professionals' Beliefs, Experiences, and Willingness to Treat Minor-Attracted Persons

There is a desire and need among minor-attracted persons (MAPs) to access support within the community, and this often begins with an approach to healthcare providers working in general medical/mental health settings. However, little is known about the experiences of these non-specialist professionals in relation to their beliefs, knowledge, and decision-making processes when working with patients who disclose sexual attractions to children. Using an online survey, this study explored the knowledge, comfort, competence, and treatment willingness of 220 non-specialist healthcare providers when faced with patients who disclose sexual attractions to children. We investigated how often such disclosures were made, clinician stigma, treatment priorities, and professionals' willingness to report MAPs to external agencies because of their sexual attractions. Some key differences were found when comparing primary medical vs. mental health professionals, including increased likelihood to view MAPs as dangerous, unable to control behaviors and that sexual attractions are an avoidable choice, in the former group. Both groups prioritized mental health treatment targets above controlling attractions and living with stigmatized attractions, although controlling or changing attractions were still relatively high priorities. Results indicated a need for further training, focusing on increasing comfort around working with MAPs, as this was associated with a greater willingness to work with this group. We identify current gaps in service provision for MAPs seeking professional support and discuss recommendations for professional training.

Sexual preference for prepubescent children is associated with enhanced processing of child faces in juveniles

Child sexual abuse offences (CSOs) represent a severe ethical and socioeconomic burden for society. Juveniles with a sexual preference for prepubescent children (PP) commit a large percentage of CSOs, but have been widely neglected in neuroscience research. Aberrant neural responses to face stimuli have been observed in men with pedophilic interest. Thus far, it is unknown whether such aberrations exist already in PP. A passive face-viewing paradigm, including the presentation of child and adult faces, was deployed and high-density electroencephalography data were recorded. The study group comprised 25 PP and the control group involved 22 juveniles with age-adequate sexual preference. Attractiveness ratings and evoked brain responses were obtained for the face stimuli. An aberrant pattern of attractiveness ratings for child vs. adult faces was found in the PP group. Moreover, elevated occipital P1 amplitudes were observed for adult vs. child faces in both groups. At longer latency (340-426 ms), a stronger negative deflection to child vs. adult faces, which was source localized in higher visual, parietal and frontal regions, was specifically observed in the PP group. Our study provides evidence for enhanced neural processing of child face stimuli in PP, which might reflect elevated attention capture of face stimuli depicting members from the sexually preferred age group. This study expands our understanding of the neural foundations underlying sexual interest in prepubescent children and provides a promising path for the uncovering of objective biomarkers of sexual responsiveness to childlike body schemes in juveniles.

Women with Sexual Interest in Children - Results from an Online Survey Among a Non-Forensic Female Sample

Little research has examined adult women's sexual interest in children, particularly in non-forensic samples. We aimed to describe characteristics of women with sexual interest in children by recruiting 52 women (mean age: 33.2 years) who have a self-identified sexual interest in children under the age of 14 years into an anonymous online self-report study. Measures of interest referred to general characteristics (e.g., age, education level), general sexuality (e.g., sexual orientation, masturbation), and sexual interest in children (e.g., exclusivity, motivation to change). Results showed that women with sexual interest in children are similar to non-forensic samples of men with sexual interest in children in previous studies and rather differ from women from the general population regarding the investigated characteristics in this study. Our results clearly indicate that women with sexual interest in children need to be taken into account in future research and clinical practice. Treatment programs preventing sexual offenses against children or the consumption of abuse material need to explicitly address females as well.

Victim selection patterns of community-residing child molesters identified by a nationwide youth-serving organization

The current study examines data extracted from revocation files of a national youth-serving organization (YSO) involving 7819 revoked individuals and 12,254 alleged child victims to better understand victim selection patterns of community-residing child molesters. These data demonstrate consistent patterns of victim selection based upon the age, gender, and YSO affiliation of each victim. We created two variables to explore whether the revoked individual was "likely pedophilic (LP)" or a "mixed offender (MO)" based upon their behaviors and patterns of victim selection. Compared with the non-LPs and non-MOs, LPs and MOs had more known victims, were more often involved in other YSOs, and were more likely to have had contact with law enforcement. We utilized a public health perspective to interpret these findings, suggesting that child sexual abuse in YSOs reflects a societal problem that is not a unique phenomenon specific to programs offering services to youth.

Stigmatization of Paraphilias and Psychological Conditions Linked to Sexual Offending

Except for pedophilia, little is known about public attitudes toward paraphilias and psychological conditions that are considered risk factors for sexual offending. In the present study we sought to compare the stigma attached to pedophilia with attitudes toward sexual sadism and antisocial tendencies (Study 1, N = 720) and with attitudes toward necrophilia and zoophilia (Study 2, N = 210) in convenience samples of community individuals. When investigating social distance intentions both studies explicitly referred to people with paraphilic sexual interests or antisocial tendencies who had not committed any crimes. In both studies, people with pedophilia emerged as highly stigmatized even though most participants showed awareness that pedophilic interests cannot be chosen or changed at will. The present studies solidify the evidence that pedophilia occupies a place in the public consciousness as less deserving of acceptance than most other sexual offending risk-relevant conditions, including ones that compare in terms of rarity.

A case of developmental pedophilia unmasked by frontotemporal dementia

A 65-year-old right-handed man gradually became socially indifferent and less active. Four years later, he was indicted for molesting children on multiple occasions. Psychomotor slowness and executive impairment contrasted with sparing of language, semantic memory, visuospatial perception, construction praxis, and right-left orientation. Neuroimaging showed asymmetric atrophy of dorsomedial frontal and anterior temporal lobes, and hypoperfusion of medial prefrontal cortex consistent with a diagnosis of behavioral variant of frontotemporal dementia. Further information revealed that the patient exhibited pedophilic behavior several years prior to symptom onset. We conclude that preexisting developmental pedophilia was "unmasked" by the underlying progressive frontotemporal degeneration.

Prioritizing Indecent Image Offenders: A Systematic Review and Economic Approach to Understand the Benefits of Evidence-Based Policing Strategies

In 2013, there were an estimated 50,000 individuals involved in downloading and sharing indecent images of children (IIOC) in the United Kingdom (UK). This poses challenges for limited police resources. We argue that police officers can make most effective use of limited resources by prioritizing those offenders who pose the greatest risk of contact offending, by nature of demonstrable pedophilia, hebephilia or dual offending status and thus, those at highest risk must be dealt with first. What is currently lacking is a clear idea of the potential scale of the problem in socio-economic terms and why, therefore, it is so important that evidence-based approaches to offender detection and investigation continue to be a top priority for funders and policy makers. A systematic literature review was undertaken to address two related questions. First, what is the scale of the problem in the UK, in terms of the number of pedophilic and hebephilic individuals who pose a risk of contact offending against a child? Second, what is the potential socio-economic burden generated by the national IIOC suspect pool if left unattended to by targeted police action? Applying population estimates of pedophilia and hebephilia to the male population (16–89 years), we estimate there are between 2,365–5,991 males with paedophila and 12,218–30,952 males with hebephilia who are likely contact offenders. Applying average prevalence and incidence based costing methods to a conservative estimate of one victim per offender, the combined socio-economic burden from these persons could amount to £236-£597 million (incident costs) increasing to £2.9-£7.3 billion (lifetime costs; £3.3-£8.3 billion including QALY measures). Applying the same costs to CEOP (2013) estimate of 50,000 IIOC offenders we estimate that between 6,000 and 27,500 dual offenders could have already committed past contact offenses, contributing an economic burden of between £97–£445 million (incident costs) increasing to £1.2–£5.4 billion (lifetime costs; £1.4–£6.2 billion including QALY measures). Future contact offenses could contribute a further burden of £16–£18.6 million (incident costs) increasing to £198–£227 million (lifetime costs; £226–£260 million including QALY measures). Drawing upon these findings, we argue for the benefits of a research-informed prioritization approach to target IIOC offenders.

Media Coverage of Pedophilia: Benefits and Risks from Healthcare Practitioners' Point of View

The fierce stigma associated with pedophilia may interfere with attempts to prevent sexual offending. Prior research on the effects of media reports about pedophilia mostly focused on their role in perpetuating stigma in the general population. In order to better understand potential benefits and risks of the media coverage on people with pedophilia and specialized prevention and treatment efforts, we conducted semi-structured qualitative interviews with 11 healthcare practitioners of the German Prevention Network “Don’t offend”. Healthcare practitioners described positive (e.g., raising awareness for prevention offers) as well as negative (e.g., perpetuating the existing public stigma) effects of the media coverage and estimated that only about one-third of media coverage portrays pedophilia realistically. To destigmatize pedophilia and benefit the prevention of child sexual abuse, a fact box for journalists was developed based on practitioners’ expert knowledge.

The World Federation of Societies of Biological Psychiatry (WFSBP) 2020 guidelines for the pharmacological treatment of paraphilic disorders

Objectives: The primary aim of these guidelines is to evaluate the role of pharmacological agents in the treatment and management of patients with paraphilic disorders, with a focus on the treatment of adult males. Because such treatments are not delivered in isolation, the role of specific psychotherapeutic interventions is also briefly covered. These guidelines are intended for use in clinical practice by clinicians who diagnose and treat patients, including sexual offenders, with paraphilic disorders. The aim of these guidelines is to bring together different views on the appropriate treatment of paraphilic disorders from experts representing different countries in order to aid physicians in clinical decisions and to improve the quality of care.Methods: An extensive literature search was conducted using the English-language-literature indexed on MEDLINE/PubMed (1990-2018 for SSRIs) (1969-2018 for hormonal treatments), supplemented by other sources, including published reviews.Results: Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for its efficacy, safety, tolerability, and feasibility. The type of medication used depends on the severity of the paraphilic disorder and the respective risk of behaviour endangering others. GnRH analogue treatment constitutes the most relevant treatment for patients with severe paraphilic disorders.Conclusions: An algorithm is proposed with different levels of treatment for different categories of paraphilic disorders accompanied by different risk levels.

Should Behavior Harmful to Others Be a Sufficient Criterion of Mental Disorders? Conceptual Problems of the Diagnoses of Antisocial Personality Disorder and Pedophilic Disorder

Generally, diseases are primarily harmful to the individual herself; harm to others may or may not be a secondary effect of diseases (e.g., in case of infectious diseases). This is also true for mental disorders. However, both ICD-10 and DSM-5 contain two diagnoses which are primarily defined by behavior harmful to others, namely Pedophilic Disorder and Antisocial (or Dissocial) Personality Disorder (ASPD or DPD). Both diagnoses have severe conceptual problems in the light of general definitions of mental disorder, like the definition in DSM-5 or Wakefield's "harmful dysfunction" model. We argue that in the diagnoses of Pedophilic Disorder and ASPD the criterion of harm to the individual is substituted by the criterion of harm to others. Furthermore, the application of the criterion of dysfunction to these two diagnoses is problematic because both heavily depend on cultural and social norms. Therefore, these two diagnoses fall outside the general disease concept and even outside the general concept of mental disorders. We discuss whether diagnoses which primarily or exclusively ground on morally wrong, socially inacceptable, or criminal behavior should be eliminated from ICD and DSM. On the one side, if harming others is a sufficient criterion of a mental disorder, the "evil" is pathologized. On the other side, there are practical reasons for keeping these diagnoses: first for having an official research frame, second for organizing and financing treatment and prevention. We argue that the criteria set of Pedophilic Disorder should be reformulated in order to make it consistent with the general definition of mental disorder in DSM-5. This diagnosis should only be applicable to individuals that are distressed or impaired by it, but not solely based on behavior harmful to others. For ASPD, we conclude that the arguments for eliminating it from the diagnostic manuals overweigh the arguments for keeping it.

Psychopathy, Neuroticism, and Abusive Behavior in Low Risk Child Sex Offenders

Personality traits are considered as an important aspect in the assessment of child sex offenders (CSOs). The current study sought to elucidate the association between neuroticism, psychopathy, and abusive behavior in low risk CSOs. 43 pedophilic CSOs and 21 controls (CTLs) completed the NEO-Personality Inventory-Revised (NEO-PI-R), Psychopathy Checklist: Screening Version (PCL:SV), and Multiphasic Sex Inventory (MSI). Our results revealed small differences in PCL scores between CSOs and CTLs, with comparatively low levels of psychopathy in both groups. Higher levels of neuroticism were associated with higher PCL scores, in both CSOs and CTLs. However, higher PCL scores in CSOs did not correlate with higher MSI total scores on the subscale child molest. These findings suggest an ambiguous role of psychopathy in CSOs: higher levels of psychopathy co-occur with higher levels of neuroticism, but psychopathy does apparently not modulate abusive behavior, at least not in low risk offenders, as currently investigated.

Profiling acquired pedophilic behavior: Retrospective analysis of 66 Italian forensic cases of pedophilia

Neurological disorders can be mis-diagnosed as psychiatric ones. This might happen to pedophilia emerging as a symptom of brain insult (i.e. acquired pedophilic behavior). This paper aims to delineate a behavioral profile that might help to identify defendants whose pedophilic behavior is likely to be the consequence of a neurological disorder. Through a systematic review of the literature, seventeen clinical and behavioral variables of the modus operandi and victimology that can distinguish between acquired and developmental pedophilic behavior have been collected. Seven of these were found to be consistent behavioral indicators (i.e. red flags) for acquired pedophilia. Cluster hierarchical analysis on the seventeen variables collected through the systematic review of the literature on cases of acquired pedophilic behavior was applied to a new dataset including 66 Italian closed cases of pedophilia. Stepwise regression and correlation analyses were carried out to further examine the differences between the clusters identified in the cluster analysis. Results revealed that the new sample was partitioned into two clusters. Individuals with ascertained acquired pedophilia were grouped together. The clusters widely differed for the prevalence of red flags (mean number of red flags in each cluster: 2.14 ± 0.79 vs 4.96 ± 0.93, p < 0.001), while no between cluster difference emerged for the other clinical and behavioral variables. Regression analysis provided a robust model that included the three most significant red flags that explain over 64.5% of the variance (absence of masking, spontaneous confession and offenders older age). An organic origin of pedophilic behavior should be suspected if red flags are present in a defendant charged with pedophilia. In those cases, an in depth trans-disciplinary neuroscientific investigation is advocated. The behavioral profile identified might help to provide a proper assessment of defendants.

Childhood maltreatment experiences and problematic sexual outcomes in adult males who have sexually offended: Further evidence of the potency of male caregiver psychological abuse

BACKGROUND

Although research on the developmental antecedents of sexual offending has tended to focus on sexual abuse, recent research in juveniles and adults who have sexually offended suggests that psychological abuse perpetrated by a male caregiver may be a particularly important factor in the development of problematic sexual interests and behaviors.

OBJECTIVE

This study aimed to extend previous findings by investigating the association between psychological abuse by a male caregiver and problematic sexual outcomes in a sample of adult males who had sexually offended.

PARTICIPANTS

Participants were 529 adult males incarcerated for sexual offenses, 21% of whom were civilly committed.

METHODS

Childhood maltreatment and problematic sexual outcomes were assessed using the Multidimensional Assessment of Sex and Aggression, a contingency-based inventory that assesses domains related to sexual aggression. Hierarchical regressions were calculated examining the association between childhood abuse types and sexual outcomes.

RESULTS

Childhood sexual abuse was associated with child sexual (β = .247, p < .001) and other paraphilic interests (β = .189, p < .001). Male caregiver psychological abuse also emerged as marginally associated with child sexual interest (β = .100, p = .059), even after controlling for other abuse types.

CONCLUSIONS

These results partially replicate recent findings in a juvenile sample and challenge conventional developmental theories of sexual offending, by suggesting that male caregiver psychological abuse may play a role in the etiology of child sexual interest among males who have sexually offended. This study also suggests a possible gender symmetry effect moderating the developmental consequences of abuse.

Self-Reported Childhood Maltreatment and Erotic Target Identity Inversions Among Men with Paraphilic Infantilism

Adults with paraphilic infantilism may desire to wear diapers or engage in infant-like role play. Erotic target identity inversions (ETII) and childhood maltreatment have been hypothesized to cause regressive interests. To evaluate these two etiological hypotheses, we surveyed the online adult baby/diaper lover community. Data from 1904 cis-gender men revealed a prevalence of pedophilic interests comparable with the general male population, arguing against ETIIs as common in paraphilic infantilism. In contrast, self-reported childhood neglect and abuse were highly prevalent, suggesting that infantilism might be correlated with childhood maltreatment. Additionally, some participants described repetition and/or sexualization of negative childhood experiences.

Are There Any Biomarkers for Pedophilia and Sexual Child Abuse? A Review

The use of biomarkers in medicine is a common and valuable approach in several clinical fields. Understanding the relationship between measurable biological processes and clinical outcomes not only is indispensable in the face of understanding physiological processes in healthy as well as in diseased organisms but also for understanding and evaluating treatment effects. Therefore, also in the context of forensic psychiatry, biomarkers and their potentially beneficial effects are of growing interest. The objective of this review is to examine if there are biomarkers that may serve as a tool to support diagnostic process, treatment evaluation, and risk assessment of pedophilic individuals and child sexual offenders. In the first part, we present an overview of the current neurobiological, as well as physiological and psychophysiological approaches to characterize pedophilia and child sexual offending. Secondly, we discuss and evaluate the impact of these approaches on the development of biomarkers for diagnosis, therapy, and risk assessment in pedophilic subjects and child sexual offenders. We conclude that a lot of research has already enhanced our neurobiological knowledge about pedophilia and child sexual offending. Although there surely exist promising parameters and approaches, in our view currently none of these is ready yet to serve as a clinically applicable diagnostic, response, or predictive biomarker for pedophilia and child sexual offending. Therefore, further work remains to be done. The development of a composite diagnostic biomarker to assess deviant sexual interest, combining several measures like functional magnetic resonance imaging, electroencephalogram, eye tracking, and behavioral approaches seems to be most promising. A valid and reliable measurement of deviant sexual interest, insensitive to manipulations could significantly support clinical diagnostic process. Similarly, regarding therapy evaluation and risk assessment, a composite biomarker to assess inhibitory control functions seems to be promising. Furthermore, the application of the Research Domain Criteria-approach, a new approach for investigating and classifying mental disorders, offers the possibility to take research to a new level.

"It's Not Something I Chose You Know": Making Sense of Pedophiles' Sexual Interest in Children and the Impact on Their Psychosexual Identity

Sexual interest in children is one of the most strongly predictive of the known risk factors for sexual reconviction. It is an important aspect of risk assessment to identify the presence of such interest, and an important task for treatment providers to address such a sexual interest where it is present. It has been argued that understanding pedophiles' deviant sexual interest in children can enhance risk assessment, management, and treatment planning. This research study aims to explore the phenomenology of deviant sexual interest in children, the impact it has on pedophilic offenders' identities, and their views on the treatability of that interest. The study used semistructured interviews and repertory grids to make sense of participants' experiences. The results revealed three superordinate themes: "'living' with a deviant sexual interest," "relational sexual self," and "possible and feared sexual self." The analysis unpacks these themes and repertory grid analysis is used to explore a subset of participants' identities in more detail. The results reveal that there needs to be an acceptance from both client and therapist that their sexual interest in children may never go away. Through this acceptance, clients could work on enhancing sexual self-regulation, recognizing their triggers, and so managing their sexual thoughts, feelings, and behavior. Implications for treatment are also discussed.

Sex Offender Risk Assessment: Where Are We and Where Are We Going?

PURPOSE OF REVIEW

Risk assessment is one of the most ubiquitous tasks in the criminal justice system, informing virtually every decision made about offenders. This review, intended for researchers and practitioners, outlines some of the most important recent advances, emerging issues, and recommendations in sex offender risk assessment.

RECENT FINDINGS

The underlying nature and purpose of risk scales is reviewed, with implications for how we should evaluate them. Limits of recidivism probability estimates are discussed, and efforts to advance a common language for describing risk levels are highlighted. Advances in risk communication and field validity are summarized. The utility of protective risk factors in risk assessments is debated. Emerging areas in assessing offender change and assessments with child pornography offenders are discussed. Despite critical advances in the last few years, there are still important gaps in knowledge, particularly for risk communication, field implementation, offender change, and child pornography offenders.

Clinical characteristics associated with paedophilia and child sex offending - Differentiating sexual preference from offence status

Contrary to public perception, child sex offending (CSO) and paedophilia are not the same. Only half of all cases of CSO are motivated by paedophilic preference, and a paedophilic preference does not necessarily lead to CSO. However, studies that investigated clinical factors accompanying and contributing to paedophilia so far mainly relied on paedophiles with a history of CSO. The aim of this study was to distinguish between factors associated with sexual preference (paedophile versus non-paedophile) and offender status (with versus without CSO). Accordingly, a 2 (sexual preference) × 2 (offender status) factorial design was used for a comprehensive clinical assessment of paedophiles with and without a history of CSO (n = 83, n = 79 respectively), child sex offenders without paedophilia (n = 32) and healthy controls (n = 148). Results indicated that psychiatric comorbidities, sexual dysfunctions and adverse childhood experiences were more common among paedophiles and child sex offenders than controls. Offenders and non-offenders differed in age, intelligence, educational level and experience of childhood sexual abuse, whereas paedophiles and non-paedophiles mainly differed in sexual characteristics (e.g., additional paraphilias, onset and current level of sexual activity). Regression analyses were more powerful in segregating offender status than sexual preference (mean classification accuracy: 76% versus 68%). In differentiating between offence- and preference-related factors this study improves clinical understanding of both phenomena and may be used to develop scientifically grounded CSO prevention and treatment programmes. It also highlights that some deviations are not traceable to just one of these two factors, thus raising the issue of the mechanism underlying both phenomena.

Why Information Matters: Examining the Consequences of Suggesting That Pedophilia Is Immutable

In this study, the impact of suggesting that pedophilia is immutable on a man's specific self-efficacy for modifying his sexual interest in children was examined in 94 men with a sexual interest in children. The participants were selected from differing contexts and included non-forensic patients, forensic patients, and participants from the Internet. Randomly distributed to two conditions, the mutable condition group received the information that experts consider pedophilia to be modifiable, whereas the immutable condition group received the information that experts consider pedophilia to be stable. Afterward, the participants' levels of specific self-efficacy for modifying their sexual interest in children were assessed. Non-forensic participants in the mutable condition reported higher levels of specific self-efficacy than those in the immutable condition. No differences in specific self-efficacy were revealed for the forensic and Internet participants when comparing the mutable and immutable conditions. It would appear appropriate to avoid generalized and absolute statements about the (im)mutability of sexual interest in children, as scientific research on this topic remains insufficient. Furthermore, given the present results, such statements might have serious consequences for an individual's belief in being able to change his sexual interest in children.

Child Sexual Abuse Perpetrators: What Forensic Nurses Need to Know

Child sexual abuse is a problem of epidemic proportions resulting in lifelong physical and mental health consequences for victims. Most child sexual abuse victims never disclose and do not receive needed treatment. Clearly, pediatric healthcare providers must understand the dynamics of child sexual abuse to better identify and protect potential victims. Forensic nurses are at the forefront of caring for victims of sexual abuse and are strong voices in the education of parents, community members, and other healthcare professionals regarding sexual abuse. Forensic nurses with a deeper understanding of child sexual abuse perpetrators will be better able to educate the public and advocate for children at risk for sexual abuse. In this article, specific types of child sexual abuse perpetration will be explored, and implications for forensic nursing will be discussed.

Web-Based Health Services in Forensic Psychiatry: A Review of the Use of the Internet in the Treatment of Child Sexual Abusers and Child Sexual Exploitation Material Offenders

In recent years, web-based health services for a variety of mental disorders have been developed and evaluated. Evidence suggests that guided internet-based therapy can be as effective as conventional face-to-face therapy. In forensic psychiatric practice, few web-based treatments have been implemented up to now. However, to our knowledge, there do not yet exist guided internet-based treatments for child sexual abusers and child sexual exploitation material offenders. This review aims at examining under what conditions patients are most likely to benefit from internet-based treatments. In addition, some computer-based health services in forensic psychiatry will be summarized and their potentials and weaknesses will be discussed. Subsequently, the review focuses on the implications for the development of online treatments for child sexual abusers as well as on a variety of ethical and legal issues that practitioners may encounter during the development, evaluation and delivery of online health services. The review will conclude with proposed quality standards for the development and implementation of web-based interventions for child sexual abusers and child sexual exploitation material offenders. By virtue of the low number of psychotherapists offering therapy to this clientele as well as individual barriers to seeking treatment such as fear of stigmatization, feelings of shame, long access routes, or limited mobility due to physical handicaps, the development of mental eHealth services in this sector could close an important healthcare gap. By increasing the density of supply, more child sexual abusers and child sexual exploitation material offenders would have the chance to engage in treatment and, ultimately, more incidents of sexual assault against minors could be prevented.

Identifying Pedophilic Interest in Sex Offenders Against Children With the Indirect Choice Reaction Time Task

Abstract. Pedophilia – a disorder of sexual preference with primary sexual interest in prepubescent children – is forensically relevant yet difficult to detect using self-report methods. The present study evaluated the criterion validity of the Choice Reaction Time (CRT) task to differentiate between a sample of child sex offenders with a presumably high rate of pedophilic individuals and three control groups (other sex offenders, non-sex offenders, and community controls, all male; N = 233). The CRT task required locating a dot superimposed on images depicting men, women, girls, or boys and scrambled pictures as quickly as possible. We used two picture sets, the Not Real People (NRP) set and the Virtual People Set (VPS). We predicted sexually relevant pictures to elicit longer reaction times in interaction with the participant group. Both CRTs showed main effects of stimulus explicitness and preferred stimulus gender. The CRT-NRP also yielded an interaction effect of participant group and stimulus maturity while the CRT-VPS showed a tendency in this direction. The overall effect size was moderate. Results offer support for the usefulness of the CRT task in forensic assessment of child sex offenders.

[Treatment structures for men with pedosexual problems]

Pedophilia is defined as a persistent or dominating sexual preference for prepubescent children characterized by persistent thoughts, fantasies, urges, sexual arousal and behavior. Less than 50% of all child abusers fulfill the diagnostic criteria and an even smaller part exclusively has a preference for children. Following psychiatric classification systems, pedophilia must be distinguished from child sexual abuse. Outpatient treatment and treatment in forensic psychiatry clinics, sociotherapeutic facilities and in correction facilities are different aspects of prevention. So-called grey area projects (Dunkelfeldprojekte) are special facilities of primary and secondary prevention. The aim is to prevent sexual abuse by reducing and controlling of risk factors.

A Meta-Analysis of Viewing Time Measures of Sexual Interest in Children

Due to unobtrusiveness and ease of implementation, viewing time (VT) measures of sexual interest in children have sparked increasing research interest in forensic contexts over the last two decades. The current study presents two meta-analyses of VT measures adapted to assess pedophilic interest to determine their discrimination between sexual offenders against children (SOC) and non-SOC groups as well as convergent validity (associations with other measures of sexual interest in children). On average, VT measures showed moderate discrimination between criterion groups (fixed-effect d = 0.60, 95 % CI [0.51, 0.68], N = 2705, k = 14) and significant convergent validity with self-reports, penile plethysmography, Implicit Association Tests, and offence behavioral measures ranging from r = .18 to r = .38. VT measures, however, provided better discrimination for adults (fixed-effect d = 0.78, 95 % CI [0.64, 0.92]) than adolescent samples (fixed-effect d = 0.50, 95 % CI [0.40, 0.61]), Q _between = 9.37, p = .002. Moreover, compared to absolute scores, using pedophilic difference scores within adult samples substantially increased VT measures' validity (fixed-effect d = 1.03, 95 % CI [0.82, 1.25], N = 414, k = 7). Results are discussed in terms of their theoretical and applied implications for forensic contexts.

The Puzzle of Male Chronophilias

In this article, I return to the idea that pedophilia, a sexual interest in prepubescent children, can be considered a sexual orientation for age, in conjunction with the much more widely acknowledged and discussed sexual orientation for gender. Here, I broaden the scope to consider other chronophilias, referring to paraphilias for age/maturity categories other than young sexually mature adults. The puzzle of chronophilias includes questions about etiology and course, how chronophilias are related to each other, and what they can tell us about how human (male) sexuality is organized. In this article, I briefly review research on nepiophilia (infant/toddlers), pedophilia (prepubescent children), hebephilia (pubescent children), ephebophilia (postpubescent, sexually maturing adolescents), teleiophilia (young sexually mature adults, typically 20s and 30s), mesophilia (middle-aged adults, typically 40s and 50s), and gerontophilia (elderly adults, typically 60s and older) in the context of a multidimensional sexual orientations framework. Relevant research, limitations, and testable hypotheses for future work are identified.

How Ego Depletion Affects Sexual Self-Regulation: Is It More Than Resource Depletion?

Rational thinking and decision making are impacted when in a state of sexual arousal. The inability to self-regulate arousal can be linked to numerous problems, like sexual risk taking, infidelity, and sexual coercion. Studies have shown that most men are able to exert voluntary control over their sexual excitation with various levels of success. Both situational and dispositional factors can influence self-regulation achievement. The goal of this research was to investigate how ego depletion, a state of low self-control capacity, interacts with personality traits-propensities for sexual excitation and inhibition-and cognitive absorption, to cause sexual self-regulation failure. The sexual responses of 36 heterosexual males were assessed using penile plethysmography. They were asked to control their sexual arousal in two conditions, with and without ego depletion. Results suggest that ego depletion has opposite effects based on the trait sexual inhibition, as individuals moderately inhibited showed an increase in performance while highly inhibited ones showed a decrease. These results challenge the limited resource model of self-regulation and point to the importance of considering how people adapt to acute and high challenging conditions.

Reliability and validity of the DSM-IV-TR and proposed DSM-5 criteria for pedophilia: Implications for the ICD-11 and the next DSM

We tested the inter-rater reliability and criterion-related validity of the DSM-IV-TR pedophilia diagnosis and proposed DSM-5 pedohebephilia diagnosis in a sample of 79 men who had committed child pornography offenses, contact sexual offenses against children, or who were referred because of concerns about whether they had a sexual interest in children. Participants were evaluated by two independent psychiatrists with an interview and questionnaire regarding demographic characteristics, sexual history, and self-reported sexual interests; they also completed phallometric and visual reaction time testing. Kappa was .59 for ever meeting DSM-IV-TR criteria for pedophilia and .52 for ever meeting the proposed DSM-5 criteria for pedohebephilia. Ever meeting DSM-IV-TR diagnosis was significantly related to self-reported index of sexual interest in children (highest AUC=.81, 95% CI=.70-.91, p<.001) and to indices of sexual interest in children from phallometric testing (AUC=.70; 95% CI=.52-.89; p<.05) or a computerized assessment based on visual reaction time and self-report (AUC=.75; 95% CI=.62-.88; p<.005). Ever meeting the proposed DSM-5 "diagnosis" was similarly related to self-report (AUC=.84, 95% CI=.74-.94, p<.001) and to the two objective indices, with AUCs of .69 (95% CI=.53-.85; p<.05) and .77 (95% CI=.64-.89; p<.001), respectively. Because the pDSM-5 criteria did not produce significantly better reliability or validity results and users are more familiar with the current DSM-5 criteria, we believe these results suggest the revision of DSM-5 and development of ICD-11 could benefit from drawing on the current DSM-5 criteria, which are essentially the same as DSM-IV-TR except for a distinction between having a paraphilia (the interest) and a paraphilic disorder (the paraphilia plus clinically significant distress or impairment).

Early parenting styles and sexual offending behavior: A comparative study

Sexual offenders, in general, report problematic rearing practices from their parents, lacking however more empirical research on this topic regarding particular subtypes of offenders. The current study examined the relationship between early parenting styles and different types of sexual offending. A total of 113 sexual offenders (rapists, pedophilic and nonpedophilic child molesters), and 51 nonsexual offenders completed the EMBU (My Memories of Upbringing), the Brief Symptom Inventory, and the Socially Desirable Response Set Measure. Results showed that rapists were less likely to remember their fathers as being emotionally warm compared with nonsexual offenders and pedophilic child molesters. In addition, compared with rapists, pedophilic offenders perceived their mothers as having been less emotionally warm to them. Overall, results showed that certain developmental experiences with parents were able to distinguish between subtypes of offenders supporting an association between distal interpersonal factors and sexual offending. These findings may have important implications for early intervention and prevention of sexual crimes. Further research using larger samples of pedophilic child molesters is recommended.

"Just dreaming of them": The Berlin Project for Primary Prevention of Child Sexual Abuse by Juveniles (PPJ)

The Berlin Project for Primary Prevention of Child Sexual Abuse by Juveniles (PPJ) offers diagnostic and therapeutic help to 12-to-18-year-old juveniles with a sexual preference for the prepubescent and/or early pubescent body of children and who apply for treatment on a voluntary basis. The project goal is to prevent primary or recurrent child sexual abuse as well as primary or recurrent use of child abuse images. Treatment aims to enable affected juveniles to obtain control over their conflictual sexual behaviors. In the present article, the origin of the PPJ; its main approach, including the conception of a media campaign; as well as results from the first year of a three-year study are presented. Further, initial characterizations of juveniles taking part in the project for the first 12 months are provided. The results confirmed that the group of 12-to-18-year-old juveniles with a sexual preference for prepubescent and/or early pubescent minors exists as a target group for primary preventive measures and that they can be assessed for their sexual preferences.

Pedophilic brain potential responses to adult erotic stimuli

Cognitive mechanisms associated with the relative lack of sexual interest in adults by pedophiles are poorly understood and may benefit from investigations examining how the brain processes adult erotic stimuli. The current study used event-related brain potentials (ERP) to investigate the time course of the explicit processing of erotic, emotional, and neutral pictures in 22 pedophilic patients and 22 healthy controls. Consistent with previous studies, early latency anterior ERP components were highly selective for erotic pictures. Although the ERPs elicited by emotional stimuli were similar in patients and controls, an early frontal positive (P2) component starting as early as 185 ms was significantly attenuated and slow to onset in pedophilia, and correlated with a clinical measure of cognitive distortions. Failure of rapid attentional capture by erotic stimuli suggests a relative reduction in early processing in pedophilic patients which may be associated with relatively diminished sexual interest in adults.

How Common is Men's Self-Reported Sexual Interest in Prepubescent Children?

Consistent evidence exists for sexual interest in children in nonclinical/nonforensic male populations. However, prevalences for community men's self-reported sexual interest in children have been based on indiscriminate definitions including postpubescent individuals, age-restricted samples, and/or small convenience samples. The present research assessed men's self-reported sexual interest in children (including child prostitution and child sex tourism) on the community level and examined the link between strictly defined sexual fantasies and behaviors involving prepubescent children. In an online survey of 8,718 German men, 4.1% reported sexual fantasies involving prepubescent children, 3.2% reported sexual offending against prepubescent children, and 0.1% reported a pedophilic sexual preference. Sexual fantasies involving prepubescent children were positively related to sexual offending against prepubescent children. Sexual interest in children was associated with subjectively perceived need for therapeutic help. In contrast to findings from forensic samples, men who reported child pornography use exclusively were identified as a subgroup differing from contact sexual offenders against prepubescent children and men who reported both child pornography use and contact sexual offenses against prepubescent children. The empirical link between child-related sexual fantasies and sexual victimization of prepubescent children and high levels of subjective distress from this inclination underscore the importance of evidence-based child sexual abuse prevention approaches in the community. Findings are discussed in terms of their relation to pedophilic disorder.

The Neurobiology and Psychology of Pedophilia: Recent Advances and Challenges

A pedophilic disorder is recognized for its impairment to the individual and for the harm it may cause to others. Pedophilia is often considered a side issue and research into the nature of pedophilia is delayed in comparison to research into other psychiatric disorders. However, with the increasing use of neuroimaging techniques, such as functional and structural magnetic resonance imaging (sMRI, fMRI), together with neuropsychological studies, we are increasing our knowledge of predisposing and accompanying factors contributing to pedophilia development. At the same time, we are faced with methodological challenges, such as group differences between studies, including age, intelligence, and comorbidities, together with a lack of careful assessment and control of child sexual abuse. Having this in mind, this review highlights the most important studies investigating pedophilia, with a strong emphasis on (neuro-) biological studies, combined with a brief explanation of research into normal human sexuality. We focus on some of the recent theories on the etiology of pedophilia such as the concept of a general neurodevelopmental disorder and/or alterations of structure and function in frontal, temporal, and limbic brain areas. With this approach, we aim to not only provide an update and overview but also a framework for future research and to address one of the most significant questions of how pedophilia may be explained by neurobiological and developmental alterations.

Connectivity and functional profiling of abnormal brain structures in pedophilia

Despite its 0.5-1% lifetime prevalence in men and its general societal relevance, neuroimaging investigations in pedophilia are scarce. Preliminary findings indicate abnormal brain structure and function. However, no study has yet linked structural alterations in pedophiles to both connectional and functional properties of the aberrant hotspots. The relationship between morphological alterations and brain function in pedophilia as well as their contribution to its psychopathology thus remain unclear. First, we assessed bimodal connectivity of structurally altered candidate regions using meta-analytic connectivity modeling (MACM) and resting-state correlations employing openly accessible data. We compared the ensuing connectivity maps to the activation likelihood estimation (ALE) maps of a recent quantitative meta-analysis of brain activity during processing of sexual stimuli. Second, we functionally characterized the structurally altered regions employing meta-data of a large-scale neuroimaging database. Candidate regions were functionally connected to key areas for processing of sexual stimuli. Moreover, we found that the functional role of structurally altered brain regions in pedophilia relates to nonsexual emotional as well as neurocognitive and executive functions, previously reported to be impaired in pedophiles. Our results suggest that structural brain alterations affect neural networks for sexual processing by way of disrupted functional connectivity, which may entail abnormal sexual arousal patterns. The findings moreover indicate that structural alterations account for common affective and neurocognitive impairments in pedophilia. The present multimodal integration of brain structure and function analyses links sexual and nonsexual psychopathology in pedophilia.
