Tenbergen, Gilian, Wittfoth Matthias, Frieling Helge, Ponseti Jorge, Walter Martin, Walter Henrik, et al.; The Neurobiology and Psychology of Pedophilia: Recent Advances and Challenges; Frontiers in Human Neuroscience; 2015(9), 344, Jun 24 2015
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 neuro-imaging techniques, such as functional and structural magnetic resonance imaging (sMRI, fMRI), together with neurop-sychological 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 neuro-developmental 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.

Schuster, Filip; Associations of the ten original Adverse Childhood Experiences (ACEs) with mental health impairments after controlling for the other ACEs (meta-analysis)
The ten original ACEs (including emotional, physical, and "sexual abuse") are associated with mental impairment among the people affected in countless studies. The corresponding bivariate associations are to a considerable extent confounding bias. The extent of the causal relationships is unresolved. [...]
Methode: A systematic literature search was conducted to search for studies that determined the associations of each of the ten original ACEs with mental impairment in "minors" or adults after controlling for each of
the nine other original ACEs (and other ACEs, if applicable). [...]
Conclusions: The causal relationships between the ten original ACEs and mental health impairments are smaller than widely suspected. In the case of several original ACEs, long-term important negative health consequences
are not to be assumed. The ACEs concept should be fundamentally
reconsidered.
Limitations: Also, because of the many uncontrolled confounding variables (including genes and other ACEs), the associations identified by the metaanalysis are not precise causal effect sizes.
Schuster, Filip; Quotes from: Associations of the ten original Adverse Childhood Experiences (ACEs) with mental health impairments after controlling for the other ACEs (meta-analysis)
The ten original ACEs (including emotional, physical, and "sexual abuse") are associated with mental impairment among the people affected in countless studies. The corresponding bivariate associations are to a considerable extent confounding bias. The extent of the causal relationships is unresolved.
[... ... ...]
Results: The magnitude of the bivariate associations between the ten original ACEs and mental health impairments is typically medium across
studies (median r=0.22), typically very small (r=0.07) after controlling for the nine other original ACEs, and even smaller (r=0.05) after controlling for additional ACEs. The ACEs incarceration of a household member (r=-0.01) and witnessing violence against the mother/parents (r=0.01) are not associated with mental health impairments after controlling for more than each of the nine other original ACEs. These associations are also very low for the ACEs "sexual abuse", divorce/separation of parents, and alcohol/drug problem of a household member (r=0.04 each).
Conclusions: The causal relationships between the ten original ACEs and mental health impairments are smaller than widely suspected. In the case of several original ACEs, long-term important negative health consequences
are not to be assumed. The ACEs concept should be fundamentally reconsidered.
Limitations: Also, because of the many ncontrolled confounding variables (including genes and other ACEs), the ssociations identified by the metaanalysis are not precise causal effect sizes.

Sima, Richard; The power of social touch; The Washington Post, Feb 09 2023
Studies show that social touch is essential to our mental well-being and can reduce stress and pain while helping us bond with one another. [...]
Social touch is so important for our well-being that we have specific cells in our skin to detect it. [...]
Social touch causes the release of the social-bonding hormone oxytocin in the brain, which is thought to reduce anxiety and pain. [...]
Research opens up a potential target for future therapeutics that can use the skin to access reward circuits to help treat trauma or depression.

Schuster, Filip; Approximately 0.5 percent of all "perpetrators" of "sexual abuse" of "minors" are "pedophilic" men, Feb 17 2022
For orientation in advance, a brief summary of the following calculation: According to the available Darkfield studies,

- 74 percent of all "perpetrators" of "sexual abuse" of "minors" are "minors" (people under 18 years of age) and
- only 26 percent are adults (women and men 18 years of age and older).
- 14 percent of all "perpetrators" are female and
- 86 percent are male, according to available dark field studies.

We assume here that this result based on "minor" and adult "perpetrators" also applies to adult "perpetrators". Then

- 4 percent of all "perpetrators" are women and
- 23 percent are men.

According to two Darkfield studies, about 2 percent of all adult males who have "sexually abused" "minors" are estimated to have a sexual age preference for prepubescents (people in the 0 to 9/10 age range). Accordingly, approximately 0.5 percent of all "perpetrators" of "sexual abuse" of "minors" are "pedophilic" adult males.
Schuster, Filip - 2022; The age of the girls and the boys in the Tanner stages
The studies listed were identified by the author in 2017 using a systematic literature search. ...
In recent decades, the age at which girls reach puberty has declined by 0.24 years per decade, [...] Therefore, it may be that in the last five years since the literature review was conducted, the age at reaching puberty has decreased slightly. ...
Girls do not typically reach puberty at age eleven, as has been widely claimed (...), but rather at age nine. ...
Girls are not in Tanner stage 4 (...) at 15 to 16/17 years, but at twelve to 14 years. ...
Accordingly, the desire of girls from the age of ten and of boys from the age of eleven was and is not evidence of preferential desire of prepubescents ("pedophilia").

Safiye Tozdan, Arne Dekker, Dr Phil, Janina Neutze, and Pekka Santtila, & Briken Peer; Sexual Interest in Children Among Women in Two Nonclinical and Nonrepresentative Online Samples; Sex Med; 2020(1), 1-14
Regarding women, little research is available about the prevalence of sexual interest in children (SIC), especially in nonclinical samples.
The present study aimed to investigate the extent to which adult women from 2 nonclinical and non-representative samples indicate sexual interest in prepubescent and/or pubescent children.
Participants took part in an online survey either via general websites or via websites directed toward individuals with a SIC.
The samples included are non-representative and therefore not generalizable to the female population.
Nevertheless, they strongly suggest that SIC is a phenomenon also found in women. We therefore recommend professionals in the field of sexual medicine to increase their attention and engagement for women with SIC. Based on the present results, the development of preventive treatment services specifically tailored to women with a SIC has to be strongly encouraged in the near future.

Schuster, Filip; Open letter to Michael Seto,..., Jul 20 2019
This open letter was sent by letter and e-mail to the five persons / organizations on July 20th 2019 and will be sent in addition to the information by e-mail to sexologists publishing about "pedophilia".

For many years, you have systematically spread false information about the age at the onset of puberty. As evidenced below, the puberty of girls begins several years before the age information that you give. Your false age ratings cause people to receive a "pedophilia" diagnosis, even though these people are not "pedophilic" according to your own "pedophilia" definition of the desire of pre-pubertals.

Santangelo, Ashley; A Blueprint When Feeling Blue: How A Mental Health Diagnosis Can Be Empowering
A Canadian study that was facilitated in 2001 explored factors in the lives of adults with a mental illness that influenced the degree of empowerment felt in their lives. Every participant was in some kind of mental health treatment (either therapy, medication management, a peer support group, or a combination of more than one treatment method). The study revealed that the two factors below had a significant influence on empowerment:

1.) Personal motivation: When consumers of mental health services were able to take more initiative in making choices, it resulted in improved confidence, skill development, and greater sense of control over their lives.

2.) Supportive Relationships: Consumers of mental health services reported feeling more empowered when their personal and professional relationships were supportive and fair. This resulted in increased participation and involvement in the community, particularly if they were able to connect with a community of peers who they saw on a regular basis.

I have actually witnessed the peer support models become increasingly common in the past decade and know of individuals who have discovered a sense of purpose once they become involved in peer support. These kinds of groups and relationships have the potential to offer mental health consumers a sense of connection that may be difficult to find elsewhere.

Giving and receiving mutual support to other with a mental illness can provide empowerment and a sense of purpose.
Seto, Michael C.; Pedophilia and Sexual Offending against Children - Theory, Asessment, and Intervention - Second Edition - Quotes and Summaries; 329 pp
This new edition represents a critical review and integration of many active lines of research on pedophilia, hebephilia, sexual offending against children, incest, risk assessment, and treatment. My aim is to provide an accessible and scholarly book that summarizes the evidence to drive better research, policies, and practices, to prevent sexual offenses against children and to improve the lives of persons with pedophilia or hebephilia.

Some readers may be surprised that helping persons with pedophilia or hebephilia is part of my aim in this book. I ask you to imagine, whatever your sexual preferences are, that social norms and laws prohibited you from expressing your sexuality in the way you would like. Very serious consequences could result if you did express your sexual interest, including loss of employment; social ostracism; estrangement from family and friends; long prison sentences; and then a range of legal restrictions regarding residence, movement, and public notifications about you post sentence. Even if you never expressed your sexual interest, you would live in anxiety and fear because of the severe stigma associated with your sexual interest, so that it would be very difficult if not impossible to disclose to family members, friends, and others around you. That is the situation that persons with pedophilia or hebephilia currently face.

The field seems to have moved from a vigorous debate about whether sex offender treatment works at all to more fine-rained questions about what forms of treatment, for who, and under what conditions. This does not negate the many questions regarding assessment and treatment
for different populations, including non-offending persons with pedophilia, females, and juveniles.

I hope this book is a useful starting point for researchers, practitioners, and policymakers in setting an agenda for further work on these important topics. I am looking forward to the next decade of progress.

Krone, Tony, & Smith Russell G.; Trajectories in online child sexual exploitation offending in Australia; Trends & issues in crime and criminal justice, No. 524 January 2017
Although the full extent and nature of the sexual exploitation of children is only beginning to be recognised, it is a problem of global significance that requires strong and effective responses. The extent to which the viewing of child exploitation material (CEM) is linked to involvement in producing such material, sharing it and using it to groom and then assault children is a key concern. Most such material is held online, and it is important to understand how offenders use the internet to access CEM and to groom children for sexual exploitation.
This exploratory study examines data relating to a sample of offenders convicted of online child sexual exploitation offences under Australian Commonwealth law, to determine how online forms of child sexual exploitation and offline child sexual exploitation, or contact offending, are related.
The majority of offenders in this study appeared to commit only online offences, although in a minority of cases there was a connection between exploitative material, grooming and contact offending.
This study is an important early step in improving our understanding of offenders and points to the need for further assessment of the nature of online child sexual exploitation and its relationship to other forms of sexual and violent offences.

Kärgel, Christian, Massau Claudia, Weiss Simone, Walter Martin, Borchardt Viola, Krueger Tillman H. C., et al.; Evidence for ... Inhibitory Control Abilities ...; Human Brain Mapping; 38(2), , Oct 21 2016
Neurobehavioral models of pedophilia and child sexual offending suggest a pattern of temporal and in particular prefrontal disturbances leading to inappropriate behavioral control and subsequently an increased propensity to sexually offend against children. However, clear empirical evidence for such mechanisms is still missing. [...]
We compared behavioral performance and neural response patterns among three groups of men [...]: pedophiles with (...) and without (...) a history of hands-on sexual offences against children as well as healthy non-offending controls (...).
As compared to offending pedophiles, non-offending pedophiles exhibited superior inhibitory control [...] while no significant differences were found between pedophiles and healthy controls.
Data therefore suggest that heightened inhibition-related recruitment [...] is related to better inhibitory control in pedophiles who successfully avoid committing hands-on sexual offences against children.

This article aims to provide more insight into pedophilic attraction and risk and protective factors for offending in non-clinical pedophiles.

Fifteen participants were interviewed about sexuality, coping, and sexual self-regulation. Many participants struggled with acknowledging pedophilic interest in early puberty and experienced psychological difficulties as a result. Furthermore, many committed sex offenses during adolescence when they were still discovering their feelings.

Early recognition of risk factors and early start of interventions seem vital in preventing offending. Moreover, results suggest that risk for offending can be diminished by creating more openness about pedophilia and by providing pedophiles with social support and control.

Jahnke, S., Schmidt A. F., Geradt M., & Hoyer J.; Stigma-related stress and its correlates among men with pedophilic sexual interests.; Archives of Sexual Behavior; November 2015,
Despite decades of research on the adverse consequences of stereotyping and discrimination for many stigmatized groups, little is known about how people with pedophilia perceive and react to stigma.
In this article, we present a framework that outlines how stigma-related stress might negatively affect emotional and social areas of functioning, cognitive distortions, and the motivation to pursue therapy, all of which may contribute to an increased risk of sexual offending.
We tested our hypotheses in an online survey among self-identified German speaking people with pedophilia (N = 104) using a wide range of validated indicators of social and emotional functioning (...). Specific risk factors such as self-efficacy, cognitive distortions and the motivation to seek treatment were also assessed.
In line with our hypotheses, fear of discovery generally predicted reduced social and emotional functioning. Contrary to our predictions, perceived social distance and fear of discovery were not linked to self-efficacy, cognitive distortions, or treatment motivation. [...]

Schuster, Filip; Every fifth boy and man is pedophilic or hebephilic, Sep 24 2014
Abstract

A meta-analysis of all seven relevant phallometric studies reveals that 22% of normal men show greater or equal sexual arousal to child stimuli (individuals up to 13 years old) than to adult stimuli.
Combined results of two of these studies reveal male prevalence rates of about 3% for pedophilia (mostly sexually aroused by prepubescents) and about 16% for hebephilia (mostly sexually aroused by pubescents). Details of these studies are described, and implications of the results for sexual science and society are discussed.
Smith, Deirdre M.; Dangerous Diagnoses, Risky Assumptions, and the Failed Experiment of 'Sexually Violent Predator' Commitment; Oklahoma Law Review, Jun 11 2014
In the 1997 opinion, Kansas v. Hendricks, the U.S. Supreme Court upheld a law that presented a new model of civil commitment. The targets of these new commitment laws were dubbed “Sexually Violent Predators,” and the Court upheld this form of indefinite detention on the assumption that there is a psychiatrically distinct class of individuals who, unlike typical recidivists, have a mental condition that impairs their ability to refrain from violent sexual behavior. And, more specifically, the Court assumed that the justice system could reliably identify the true “predators,” those for whom this unusual and extraordinary deprivation of liberty is appropriate and legitimate, with the aid of testimony from mental health professionals.
This Article evaluates the extent to which those assumptions were correct and concludes that they were seriously flawed and, therefore, the due process rationale used to uphold the SVP laws is invalid. The category of the “Sexually Violent Predator” is a political and moral construct, not a medical classification. The implementation of the laws has resulted in dangerous distortions of both psychiatric expertise and important legal principles, and such distortions reveal an urgent need to re-examine the Supreme Court’s core rationale in upholding the SVP commitment experiment.

Segal, David; Does Porn Hurt Children?; New York Times Sunday Review
[...] After sifting through [276 research] papers, the report [of a Commision] found a link between exposure to pornography and engagement in risky behavior, such as unprotected sex or sex at a young age. But little could be said about that link. Most important, “causal relationships” between pornography and risky behavior “could not be established". [...]
Among the most prolific and revered researchers to examine teenagers and pornography is a duo in the Netherlands, Jochen Peter and Patti M. Valkenburg. The pair has been publishing studies about this issue for nearly a decade, most of it based on surveys of teenagers. “when teens watch more porn they tend to be more dissatisfied with their sexual lives. This effect is not really a strong effect, though." ... The pair also found that adolescents who watch more porn than their typical peers are generally less averse to casual sex. [...]
“I would be very cautious saying that what we found in the Netherlands is applicable in the U.S.,” Mr. Peter said. “Our findings are in a country that is pretty liberal when it comes to adolescent sexuality.” [...]
“One of our recommendations is that children should be taught about relationships and sex at a young age,” Professor Horvath “One of our recommendations is that children should be taught about relationships and sex at a young age,” Professor Horvath said. [...]
At a minimum, researchers believe a parent-teenager conversation about sexuality and pornography is a good idea, as unnerving to both sides as that may sound.

Seto, Michael C.; Is Pedophilia a Sexual Orientation?; Arch Sex Behav; 41, 231–236
In this article, I address the question of whether pedophilia in men can be construed as a male sexual orientation, and the implications for thinking of it in this way for scientific research, clinical practice, and public policy.
I begin by defining pedophilia and sexual orientation, and then compare pedophilia (as a potential sexual orientation with regard to age) to sexual orientations with regard to gender (heterosexuality, bisexuality, and homosexuality), on the bases of age of onset, correlations with sexual and romantic behavior, and stability over time. I conclude with comments about the potential social and legal implications of conceptualizing pedophilia as a type of sexual orientation in males.

There was no statistically significant association between sexual abuse and a diagnosis of schizophrenia or somatoform disorders. 
No longitudinal studies that assessed bipolar disorder or 
obsessive-compulsive disorder were found. 
Associations between sexual abuse and depression, eating disorders, and posttraumatic stress disorder were strengthened by a history of rape.
Conclusion: A history of sexual abuse is associated with an increased risk of a lifetime diagnosis of multiple psychiatric disorders.

Seto, Michael C., Hanson Karl R., & Babchishin Kelly M.; Contact Sexual Offending by Men With Online Sexual Offenses; Annals of Sex Research · December 2010
Abstract
There is much concern about the likelihood that online sexual offenders particularly online child pornography offenders) have either committed or will commit offline sexual offenses involving contact with a victim. This study addresses this question in two metaanalyses:
[1] the first examined the contact sexual offense histories of online offenders,
whereas
[2] the second examined the recidivism rates from follow-up studies of online
offenders.
[1] The first meta-analysis found that approximately 1 in 8 online offenders (12%)
have an officially known contact sexual offense history at the time of their index offense (k = 21, N = 4,464). Approximately one in two (55%) online offenders admitted to a contact sexual offense in the six studies that had self-report data (N = 523).
[2] The second meta-analysis revealed that 4.6% of online offenders committed a new sexual offense of some kind during a 1.5- to 6-year follow-up (k = 9, N = 2,630); 2.0% committed a contact sexual offense and 3.4% committed a new child pornography offense.
The results of these two quantitative reviews suggest that there may be a distinct subgroup of online-only offenders who pose relatively low risk of committing
contact sexual offenses in the future.
Udell, Wadiya, Sandfort Theo, Reitz Ellen, Bos Henny, & Dekovic Maja; The relationship between early sexual debut and psychosocial outcomes: A longitudinal study of Dutch adolescents; Archives of Sexual Behavior
In a longitudinal dataset of 470 Dutch adolescents, the current study examined the ways in which early sexual initiation was related to subsequent attachment, self-perception, internalizing problems, and externalizing problems. For male adolescents, analyses revealed general attachment to mother and externalizing problems at Wave 1 to predict to early transition at Wave 2. However, there was no differential change in these psychosocial factors over time for early initiators of sexual intercourse and their non-initiating peers. For female adolescents, the model including psychosocial factors at Wave 1 did not predict to sexual initiation at Wave 2. However, univariate repeated measures analyses revealed early initiators to have signi?cantly larger increases in self-concept and externalizing problems than their non-initiating female peers. While the difference between female early initiators and non-initiators were statistically signi?cant, the mean levels of problem behaviors were very low. The ?ndings suggest that, contrary to previous research, early sexual initiation does not seem to be clustered with problem behaviors for this sample of Dutch adolescents. [A]
