This is best I've got: Pedophilia - Wikipedia, the free encyclopedia
It's one of those things I don't particularly wanna go researching too much, in case I set of some internet alert, of what have ya.
I've checked it out a little in the past. I was a psych major, and had access to academic studies, etc.
Not exactly a topic of interest, but it came up from time to time (since I was studying primary teaching).
There is research on this. Quite a bit, actually, although it's limited due to the difficulty in controlling and testing anti-social behaviours in a clinical fashion, as well as the general distaste for the topic, I would think.
But based on memory and what I read, there was no clear evidence rehabilitation was successful. Pedophile attraction to children seemed uneffected by various clinical interventions, and the best that could be achieved was behavioural control rather than modification.
In short, much like hetero or homosexual attraction, to be honest.
