No, the “childhood sexual abuse” did not consist of incidents in which anyone was “busted” or “convicted”. These were self-reported incidents that fell into the parameters designed by the researchers, and that the subjects did not necessarily consider abuse. The subjects were 4244 adult men who had recently had anal sex with another man (not child). They were interviewed about their sexual experiences through age 17, and anything they described that fit the researchers’ definition of “childhood sexual abuse” was recorded as such. There’s nothing in this article to suggest that even a single one of these 4244 men was found (either by interview or by court proceeding) to have ever been the perpetrator of an illegal sexual act with anyone (presumably some had, given the sample size, but there’s no evidence the researchers gathered any evidence regarding that type of activity by the study subjects). The study tried to show a correlation between being a “victim” of “childhood sexual abuse” and later risky sexual behavior among adult homosexual men.
