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.

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.

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.

"Seto notes, accurately, that many people inaccurately conflate pedophilia with sex offending against children. In this book, Seto discusses the distinctions between the two, delineating the potential causes of sex offending against children. These causes may well include pedophilia — that is, an actual sexual attraction to prepubertal children of some persistence and strength — but may in some cases be limited to other factors, especially those associated with antisociality. ... ... ...
Seto’s book is an excellent, nuanced review of the current state of the literature. The book shows excellent breadth and depth in its coverage and analysis. Thoseworking in this specialty, even those with considerable experience, would gain much from a careful reading of Pedophilia."
