Perhaps you cited the wrong link? I only read the abstract of this dissertation, but the sample size was only 59 psychologists, and the most salient conclusions were that sexual abuse is perpetrated more often by male Ts with female clients; Ts at midlife, experiencing a recent loss, and that childhood emotional abuse was the strongest predictor.

So the lesson I would take from this is to avoid male Ts who experienced emotional abuse in childhood. I can predict an outcry of reponses denouncing such "advice." Agreed--because correlation is not causation.
