What % of CSA offenders are pedophiles?

[chronic_ally]

Note that several of the below studies reference the DSM-IV, which defined pedophilia as a disorder. The DSM-V does not.

Most cases of child sexual abuse remain undetected (Finkelhor, 1994) and subsequently so do most sexual abusers of minors. These undetected cases (of any offence) constitute what is referred to as “Dunkelfeld” in German (literally “dark field”), implying we know very little about them.

It may be assumed that some Dunkelfeld offenders have a sexual preference for minors. It appears unlikely, however, to ever know how this proportion compares with the 25 to 50% found amongst detected offenders of child sexual abuse (Marshall, 1997; Marshall & Fernandez, 2003; Seto, 2008).

Using the 90% specificity cutoff score of .39 on the Pedophilic Index, 27% (298 out of 1,113) of the child molesters were identified as having pedophilic interests.

A retrospective chart review was undertaken of all clients entering treatment in a community-based sexual offender clinic located in a metropolitan area in the northwestern United States. The clinic began enrolling clients in 1973. Data collection continued for the purposes of this study through 1997. A total of 7,275 clients met the study criteria of being male, 18 years of age or older, and a client whose chief mode of offending and type of victim selected could be sufficiently defined as belonging to one of the following categories:

1. Child molesters, female victims: Men who molested at most two female children in a situational context.
2. Child molesters, male victims: Men who molested at most one male child.
3. Heterosexual pedophiles: Men who molested more than one female child and showed a preference for female children or a predatory style of offending.
4. Homosexual pedophiles: Men who molested more than one male child and showed a preference for male children or a predatory style of offending.
5. Exhibitionists: Men who exposed themselves and did not molest children or rape.
6. Rapists: Men who raped and did not molest children or expose.

Those showing a sexual preference disorder, namely pedophilia (erotic preference for prepubescent minors, i.e. showing Tanner stage 1) or hebephilia (erotic preference for pubescent minors, i.e. showing Tanner stages 2 and 3). These account for approximately 40% of officially known offenders.

As shown in §7.2.1.2, 20% of suspects who undergo a personality assessment are found to have deviant sexual preferences, including preferences other than paedophilia; in other words, 80% do not have deviant sexual preferences. The figure of 20% is probably not an accurate measure since the public prosecutor is more likely to request a personality assessment if a suspect displays signs of sexually deviant interests.

Experimental sample consists of 146 forensic cases (all men), they committed child molestation in years 2005–2012. According to the criteria (DSM-IV-TR) for pedophilia, penile plethysmography (PPG), actual clinical and case history data were used for the diagnosis determination. Obtained clinical and sociodemographic data were statistically evaluated.

Only a small part (16,2 %) of sexual offenders against children meet the criteria (DSM-IV-TR) for pedophilia.
