RESUMO

People with a sexual interest in children face significant barriers to seeking and receiving mental health treatment. This review aims to bridge the gap between the treatment needs and experiences of pedohebephiles, and the services aiming to support them. Reviewers screened 1705 database hits and extracted findings from 22 qualitative, 15 quantitative, and 3 mixed-method studies on the treatment needs and experiences of pedohebephiles. Research suggests that this population experiences significant levels of distress, depression, and anxiety related to their sexual interest. Many individuals belonging to this population would seek (median = 42.3%), or have sought (median = 46.5%), treatment to cope with their sexual interest or with potential related mental health repercussions. Their experiences in treatment have been mixed, with some reporting positive experiences with empathic therapists and others reporting rejection. Most frequently, pedohebephiles report fear of exposure and rejection as barriers to seeking treatment, in addition to fear of the legal repercussions. The current study is the first to summarize and discuss previous findings on the treatment needs and experiences of pedohebephiles. The findings indicate that the treatment needs of pedohebephiles often remain unaddressed. Suggestions to increase the fit between treatment services and the needs of pedohebephiles are put forward.

RESUMO

From a case report of a person with pedophilic disorder, this paper focuses on the issue of pedophilia, child sexual abuse, and the need for specific prevention and treatment strategies in Brazil. It seems inevitable to increase awareness for this topic within the mental health care system to protect children and reduce the risk for sexual offense in individuals at-risk. This is a case report of an individual, known by medical-psychiatric and forensic facilities for a past history of patricide, who revealed his pedophilic fantasies and behavior belatedly. To assess a pedophilic disorder and screen for other paraphilic contents, a screening questionnaire and clinical interview were used during the patient hospitalization in 2020 for a proper evaluation of sexual history and past offending behaviors. A review of the literature on pedophilia prevention programs was also carried out. WW is a middle-aged man admitted to a psychiatric unit for a severe episode of major depressive disorder and at risk of suicide. During recovery, he reported pedophilic fantasies and behaviors in his life. Sexual fantasies involving children and actual sexual offenses have remained unknown to mental health professionals and unreported to legal authorities. WW's case alarmingly emphasizes the need for the training of health care professionals and for preventive strategies in Brazil for those who are at risk of engaging in offending sexual behaviors in a combined and intensive effort to protect children from sexual offense.

RESUMO

BACKGROUND: Lay perceptions of persons who download and distribute Child Sexual Abuse Material (CSAM) is an underexplored subject. There is a need for understanding the factors that influence perceptions as the public perceptions have implications for endorsement of sex offender rehabilitation that in turn can influence the availability of treatment programs and stigma for help-seeking. OBJECTIVE: To explore public perceptions of individuals that commit child sexual abuse offences, to compare the results to those obtained in a large US sample, and to explore associations between demographic variables, general perceptions and endorsement of imprisonment and treatment for individuals that commit CSAM offences. PARTICIPANTS AND SETTING: An online survey were distributed in Norway in February 2023. 618 individuals responded, 76 % were female, mean age 34.99 (SD = 14.23), the majority (>70 %) had higher education, and 44 % had children. RESULTS: Consistent with prior research, the public perceptions overestimated the risk of future contact offences and recidivism. Women overestimated the percentage of risk of contact offences and pedophilic interest more than men. The overestimation was significantly less in this sample compared to the US sample (d = 0.39-0.96). Those working with online child abuse had perceptions of persons committing CSAM offences that were more aligned with empirical findings. Demographic variables were only marginally associated with endorsement for treatment and imprisonment, except for having children, which was associated with endorsement of imprisonment. Perceived risk of contact offences, pedophilic preference, and assumed childhood sexual victimization were associated with perceptions of individuals committing CSAM offences as different than those committing physical sexual abuse and both endorsement of treatment and imprisonment. CONCLUSIONS: The perceptions of those who commit CSAM offences showed a stronger association with endorsement for treatment and imprisonment than demographic variables.

RESUMO

The present study examined distinctions between child (n = 30) and adult (n = 212) sexual homicide offenders (SHOs) in Australia and New Zealand, contributing to the limited international research on the subject. Data, primarily sourced from judges' sentencing comments on AustLII and New Zealand Legal Information Institute, revealed significant differences. Child SHOs displayed elevated rates of pedophilia, sexual deviance, and adverse childhood experiences, including sexual abuse. They were more likely to be married, cohabitate, and target familial victims. Their crimes were more often committed during daylight and outdoors, involving tactics such as victim conning, restraints, strangulation, and hiding victim's bodies. No significant group differences emerged regarding offenders' psychopathy or sexual sadism scores. Results were interpreted in line with child SHOs' deviant sexual preferences and the routine activity theory. The study, as the first investigating child sexual homicides in Australia and New Zealand, sets the foundation for an evidence-based approach to policy and practice.

RESUMO

En prisión existen programas específicos de tratamiento para condenados por agresión sexual a menores; sin embargo, quienes además tienen pedofilia, requieren una atención específica. El objetivo del presente estudio es doble: primero, ofrecer una propuesta de intervención específica para pedofilia en el entorno penitenciario basada en la evidencia científica disponible y complementaria al Programa de Control de la Agresión Sexual y después, justificar dicha propuesta a través del caso de un interno con pedofilia. En concreto, proponemos una intervención individual y centrada en personas con pedofilia; trabajando la baja autoestima, evaluando la ideación suicida y reestructurando las distorsiones cognitivas con menores, facilitando la creación de relaciones personales funcionales con adultos, evaluando la polivictimización pasada y su posible influencia sobre la conducta sexual posterior, proporcionar a los internos psicoeducación sobre pedofilia; atender de forma específica las fantasías sexuales con menores, evitando las conductas disexuales y la eliminación del consumo de material abusivo.(AU)


There are specific treatment programs in prisons for those convicted of sexually assaulting minors; however, those who also have pedophilia require specific attention. The aim of this study is twofold: first, to offer a specific intervention proposal for pedophilia in the prison setting based on the available scientific evidence, and complementary to the Sexual Assault Control Program, and second, to justify this proposal through the case of an inmate with pedophilia. Specifically, we propose an individual intervention focused on people with pedophilia; working on low self-esteem, assessing suicidal ideation and restructuring cognitive distortions with minors, facilitating the creation of functional personal relationships with adults, assessing past polyvictimization and its possible influence on subsequent sexual behavior, providing inmates with psychoeducation on pedophilia; specifically addressing sexual fantasies with minors, avoiding dyssexual behavior, and eliminating the consumption of abusive material.(AU)

RESUMO

PURPOSE OF REVIEW: Web-based programs to prevent sexual offense perpetration could provide an opportunity that avoids many of the barriers associated with in-person treatment. The aim of this systematic review is to give an overview of the literature on web-based initiatives aimed at sexual offense perpetration prevention published during the last 10 years (2013-2023) and to report data on the efficacy as well as issues of the discussed initiatives. RECENT FINDINGS: We included 18 empirical studies discussing web-based perpetration prevention initiatives, of which six are randomized controlled trials. Among the articles, four cover programs focusing on prevention of sexual reoffending and 14 discuss programs aimed at preventing initial sexual offenses. Evaluations and observations of web-based initiatives aimed at preventing sexual offense perpetration show overall promising results and are well-appreciated. However, evaluation studies are scarce and more randomized controlled trials replicating this effect are warranted.

RESUMO

Suicide represents a significant public health problem, with around 800,000 deaths per year worldwide and up to 20 times as many episodes of self-harm and suicide attempts. Members of stigmatized groups may experience increased risk of suicide due in part to stigma-related factors, such as expectations of rejection, internalization of negative stereotypes, or potential for greater social isolation. Research suggests that adults who are attracted to children face extreme stigma, even those who do not commit sexual crimes involving children. Adults who are attracted to children also experience significantly increased risk for suicidal ideation and behavior (SIB) compared to general population samples. The current study sought to explore experiences with SIB among adults attracted to children to better understand factors underlying suicidality in this population. The lead author conducted semi-structured interviews in a community sample of 15 adults attracted to children who self-reported some form of SIB in their lifetime. Using interpretative phenomenological analysis, the lead author explored and interpreted interview data to generate themes driven by respondents' characterizations of their SIB. Superordinate themes related to suicidality in this sample included low self-esteem or self-worth, cumulative impacts of the attraction and other stressors, and concerns about the ability to have a positive future due to the attraction. Findings underscore the importance of addressing internalized stigma, treating problems like depression and social isolation, and instilling hope for the future to promote mental health and prevent SIB among adults attracted to children.

RESUMO

This study investigated the psychiatric, paraphilic, and forensic profiles of men who were convicted of sexual offenses. It also examined childhood trauma exposure in the group with potential paraphilia. The study was performed in the closed prison located in the Istanbul Silivri Penal Institutions Campus. The interview data of 100 men convicted of sexual offenses were obtained from the psychiatric interview notes based on the DSM-5 criteria, the results of the 28-item Childhood Trauma Questionnaire administered to the participants with paraphilia, and the forensic profiles from examination files. It was found that 39% of individuals were drug users and 36% were alcohol users. Considering the crime scenes, 42% of men convicted of sexual offenses committed the offense in their own house. Pedophilia was the most common among men with paraphilia (59%). The victim age was significantly lower (p < .001), and the male victim ratio was higher (p < .05) in the group with paraphilia than in the group without paraphilia. Sexual offenses against children aged 10 years and below and against males may be suggestive of paraphilia and an increased risk of recidivism.

RESUMO

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.

RESUMO

This study sought to examine neuropsychological functioning in men with pedophilic disorder (PD), in order to assess whether findings from prior neuropsychological studies are replicated in a diverse sample including men with non-contact sexual offenses. It was hypothesized that when non-contact offenders are included in the study, a slowed processing speed will emerge as the only finding unique to men with PD. A comprehensive neuropsychological battery was administered to 58 men convicted of a sexual offense, 20 of whom were classified as having PD. The sample included men with contact sexual offenses (n = 33), non-contact sexual offenses (n = 5), and child sexual abuse material (CSAM) offenses (n = 20). Test performance was compared by PD status. Participants with PD performed significantly better on verbal memory and visual discrimination than those without PD. Men with PD made more errors on a set-shifting task but no significant differences were seen in domains of attention, intellectual functioning, visual learning and memory, visuospatial ability, or language ability. Effect sizes were generally small, although some medium effects were seen (visual discrimination and verbal learning and memory). Scores in both groups (with and without PD) were generally in the average range across tasks. Within the subgroup of CSAM offenders, minimal differences emerged between those with and without PD, although those with PD were slower on visuomotor set-shifting but made fewer errors (d = - 0.89). CSAM offenders with PD were in the high average range on many tasks of intellectual functioning; however, a potential trend was identified such that CSAM offenders without PD had lower scores on a task of verbal learning and memory, with medium effect sizes observed. As few differences in neuropsychological functioning emerged when comparing offenders with and without PD, differences demonstrated in prior research may be better attributed to contact offending status rather than sexual interest.

RESUMO

The widespread conflation between having a sexual interest in children and engaging in sexually abusive behavior contributes significantly to elevated levels of stigma targeted at people living with a sexual interest in children. Stigmatization and societal punitiveness surrounding people living with these interests can impact their well-being, obstruct help-seeking, and potentially increase risk of offending behavior. Recent quantitative research employing stigma intervention strategies has produced encouraging results in reducing stigmatizing attitudes toward this population. The current study sought to expand on quantitative research findings to explore qualitatively the facilitators and barriers to understanding and accepting people living with sexual interest in children. Thirty participants were interviewed following completion of an online stigma intervention study. Participants were asked about their attitudinal responses to the earlier study and how personal and professional experiences contributed to shaping their attitudes surrounding people living with a sexual interest in children. Reflexive inductive thematic analysis was used to explore what factors promote understanding and what factors act as barriers to understanding people with sexual interest in children. The significance of experiences which challenged the dominant social narrative was identified across several themes which facilitated understanding and acceptance of people who have a sexual interest in children. Themes which reflected barriers to understanding included difficulty comprehending alternate narratives, parental concern, and reinforcement of current stereotypes. Implications for developing stigma-reduction interventions and future research are discussed.

RESUMO

OBJECTIVE: To study visual event-related potentials (ERPs) associated with presentation of erotic pictures in backward masking condition in order to investigate perception, attention and information processing underlying the initiation and maintenance of abnormal sexual behavior in pedophilia. MATERIAL AND METHODS: Participants (58 males committed sexual offenses against children) were divided into the pedophilia group (n=38) and the control group without disorders of sexual preference (n=20). Three types of stimuli were used: neutral pictures of nature (S1), adult heterosexual erotic pictures (S2) and erotic pictures with children (S3). Posterior N1 (N140) and anterior N1 (N120) and P3 (P320) ERP components were included in analysis. RESULTS: In both groups, the perception of erotic stimuli was accompanied by a significant increase in the amplitude and prolongation of the latency of the N140 and P320 components (p<0.001). N140 changes were characterized by right-hemispheric bias in both groups, however, asymmetry was observed for amplitude in the control group, and for latency - in the pedophilia group; besides, reactivity to S3 stimuli was weaker than to S2 ones in the pedophilia group. N120 amplitude was elevated significantly in response to S2 stimuli in the control group, and no changes were found in the pedophilia group. Between-group differences were revealed for early negative components N140 and N120, which parameters were entered as predictors into classification model based on discriminant analysis. The obtained accuracy of model was 87.23%. CONCLUSION: The specificity of neurophysiological reactions to erotic pictures in pedophilic patients corroborates the concept of disease as general neurodevelopmental disorder.

RESUMO

BACKGROUND: Sexual violence is a major public health issue worldwide, with a high prevalence and extensive human and financial costs. Implementing prevention programs is complex, requiring not only evidence-based practices and high ethical standards, but also close collaboration with local governments and non-governmental organizations. In order to guide and support all stakeholders necessary to achieve large-scale prevention (e.g., politicians, decision-makers, in-field professionals), it is essential to establish international benchmarks for the prevention of sexual violence. OBJECTIVE: The main goal of this collaborative study was to conduct a systematic review of the frameworks adopted by WHO, UN Women, UNESCO, and UNICEF to help prevent sexual violence worldwide, according to the PRISMA methodology. A secondary objective was to highlight the levels of prevention and determinants of health targeted by these organizations. RESULTS: Overall, 1008 references were identified, of which 50 met the inclusion criteria. All international guidelines were limited to primary or tertiary prevention, and they were not specifically dedicated to sexual violence. In addition, each organization had developed idiosyncratic prevention strategies. Common primary prevention determinants of health were still found across organizations, including education, socio-economic inequalities, and life skills training. Tertiary prevention was poorly developed and polarized between victims and perpetrators. Secondary prevention was never addressed, however, despite the effectiveness of approaches such as helplines for people sexually attracted to children. DISCUSSION: Given these results, an international French-speaking consortium of professional teams, all involved in the secondary prevention of sexual violence, was recently formed with a ratified charter presented here.

RESUMO

Objective This study investigated the reasons why pedohebephilic clients disclose their sexual attraction to children in therapy and the experiences associated with this decision among English-speaking samples. Method: The pre-registered online survey combined (1) quantitative correlational data of self-reported improvement, alliance, therapist reaction to disclosure, and the belief that mandatory reporting laws were in place, and (2) qualitative data about reasons for disclosure or no disclosure as well as perceived consequences. The sample consisted of pedohebephilic people who have been clients in therapy and have disclosed (n = 96) or not disclosed (n = 40). Results: While the disclosure and no disclosure groups did not differ in improvement or beliefs about mandatory reporting, those who had disclosed reported a stronger alliance. Clients who did not perceive the therapist's reaction as supportive reported less improvement than the no disclosure group. Thematic analysis of qualitative data identified three themes concerning motives for disclosing or not disclosing and a fourth regarding differential impacts of disclosure. Discussion: This study indicates that disclosing pedohebephilia does not in and of itself lead to improvement but is contingent on a therapist's reaction.

RESUMO

Sexual offenses are a great concern worldwide due to the devastating physical and psychological consequences the victims of such crimes often experience. It is an important task to investigate potential mechanisms that may underlie sexual offending and predispose an individual for such antisocial behavior. Advanced techniques in neuroscience are increasingly used to uncover biomarkers in psychiatric disorders and organic brain disease. As this type of research is flourishing, preliminary studies with the aim to explore the neural basis of sex offenders have started to appear. To this purpose, researchers began to study the brain's structural and functional changes and the neurocognitive profiles of sex offenders, in comparison to nonoffenders and nonsex offenders, or among different subtypes of sex offenders. Most of the research to date has focused on pedophilia, with some inconsistent findings, which hampers the translation of the results into the forensic and clinical context. Any attempt to increase convergent evidence may profit from the harmonization of data analysis and avoidance of methodological inconsistencies, which can account for the different results across studies. Today, uncovering the neural basis of sex offences has to become a priority, not only for clinical interventions, but might also be important knowledge for crime prevention.

RESUMO

PURPOSE OF REVIEW: With the Internet allowing consumers easy access to fantasy and fictional sexual materials (FSM), it is becoming increasingly important to understand the context of their use among specific populations. Of particular, social, clinical, and legal interest is FSM use by people who are attracted to children and whether this may have a risk-enhancing or protective impact on their likelihood of committing a contact or non-contact sexual offence. RECENT FINDINGS: There is a lack of data currently available in relation to the use of FSM by those with sexual attractions to children. Evidence from allied areas appears to show no meaningful associations between FSM use and sexual aggression. We propose a novel research program and some initial research questions that provide a theoretical framework for more evidence-based inquiry on FSM use by people who experience attractions to children.

RESUMO

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.

RESUMO

Emotional congruence with children (ECWC) is a psychologically meaningful risk factor for sexual offending against children (SOC). Based on previous research and theory, three models have been proposed to explain ECWC: Blockage, Sexual Domain, and Psychological Immaturity. Using structural equation modelling in a routine correctional sample of men adjudicated for sexual offences (n = 983), we found little support for all three of these models. Instead, we found that atypical sexual interests, alone, best explained ECWC, with a moderate relationship to ECWC. Using the predictors associated with each of the three models of ECWC, we identified three classes of men with a history of SOC who are high in ECWC using latent class analyses (n = 377). These three classes generally did not replicate the three models of ECWC. We instead propose three subgroups of men with histories of SOC who are high in ECWC, characterized respectively by: relationship deficits; youth and loneliness; and high sexual and general criminality. High levels of ECWC are predictive of a higher risk of sexual recidivism, regardless of class association; however, these subgroups are differentially at risk for some types of recidivism. Our findings suggest that ECWC is a multi-faceted construct, which is still not well understood.

RESUMO

Background: Pedophilic disorder (PD) entails sexual attraction to prepubertal children. A risk factor for committing child sexual abuse in PD is impaired cognitive control. However, the underlying neurocognitive mechanisms remain unclear. Methods: We performed a case-control study including 51 self-identified and help-seeking males with PD and 55 matched healthy control subjects. Functional magnetic resonance imaging and a pictorial-modified Stroop task involving computer-generated sexually implicit images were used to measure response time and brain activation. Increases in response time during the pictorial-modified Stroop task are presumably due to image-induced interference in executive functions required for task performance. Results: In PD, during the presentation of images of children compared with adults, we found increased response time (p = .005; 848 ± 92 ms vs. 826 ± 88 ms), and compared with healthy control subjects, we found increased activation in the occipital, temporal (bilateral hippocampus), parietal, frontal, cingulate, and left insular cortices; caudate (bilaterally); thalamus (mediodorsal); and cerebellum. Conclusions: Presentation of child images was associated with response interference in PD and increased engagement of brain regions involved in the processing of sexual stimuli, visual perception, self-referential thought, and executive function. We conclude that processing of child images is associated with functional and behavioral alterations in PD.

RESUMO

Background: Child sexual abuse (CSA) has become a focal point for lawmakers, law enforcement, and mental health professionals. With high prevalence rates around the world and far-reaching, often chronic, individual, and societal implications, CSA and its leading risk factor, pedophilia, have been well investigated. This has led to a wide range of clinical tools and actuarial instruments for diagnosis and risk assessment regarding CSA. However, the neurobiological underpinnings of pedosexual behavior, specifically regarding hands-on pedophilic offenders (PO), remain elusive. Such biomarkers for PO individuals could potentially improve the early detection of high-risk PO individuals and enhance efforts to prevent future CSA. Aim: To use machine learning and MRI data to identify PO individuals. Methods: From a single-center male cohort of 14 PO individuals and 15 matched healthy control (HC) individuals, we acquired diffusion tensor imaging data (anisotropy, diffusivity, and fiber tracking) in literature-based regions of interest (prefrontal cortex, anterior cingulate cortex, amygdala, and corpus callosum). We trained a linear support vector machine to discriminate between PO and HC individuals using these WM microstructure data. Post hoc, we investigated the PO model decision scores with respect to sociodemographic (age, education, and IQ) and forensic characteristics (psychopathy, sexual deviance, and future risk of sexual violence) in the PO subpopulation. We assessed model specificity in an external cohort of 53 HC individuals. Results: The classifier discriminated PO from HC individuals with a balanced accuracy of 75.5% (sensitivity = 64.3%, specificity = 86.7%, P 5000 = 0.018) and an out-of-sample specificity to correctly identify HC individuals of 94.3%. The predictive brain pattern contained bilateral fractional anisotropy in the anterior cingulate cortex, diffusivity in the left amygdala, and structural prefrontal cortex-amygdala connectivity in both hemispheres. This brain pattern was associated with the number of previous child victims, the current stance on sexuality, and the professionally assessed risk of future sexual violent reoffending. Conclusion: Aberrant white matter microstructure in the prefronto-temporo-limbic circuit could be a potential neurobiological correlate for PO individuals at high-risk of reoffending with CSA. Although preliminary and exploratory at this point, our findings highlight the general potential of MRI-based biomarkers and particularly WM microstructure patterns for future CSA risk assessment and preventive efforts.
