Cofty, thanks for posting a link to that study. I downloaded it and read it along with another one that was pertinent to the methodology that the researchers used to make up their study sample. The other one I read is this one:
Multiple Paraphilic Diagnoses among Sex Offenders
Gene G. Abel, MD; Judith V. Becker, PhD; Jerry Cunningham-Rathner, BA; Mary Mittelman, DrPH; and Joanne-L. Rouleau, PhD
I read that one so I could evaluate how it was that the researchers in the study you posted had defined their sample group and how they had arrived at the decisions they did to determine who got included and who was eliminated from their sample.
My conclusion is that a person is on real shaky ground if they think that the study can be used to extrapolate to the larger population, or even if it is a valid measurement of what the researchers say they are measuring. I am not going to get into all the problems that the study faces, but the very first clue is in the sample selection - the researchers skewed the study population before they even started - a large group that was likely heterosexual was eliminated and not even included in the study.
At least more (and better) research has been done since and most people know now that the notion that homosexuals are over represented in the population that engages in pedophilia is a myth:
