Failure of Catholic Psychology in Priest Sex Abuse?

I don't think that the apparent failure of Catholic psychology in the priest sex abuse scandal, both as a contributing factor of the sexual misconduct and as revealed in the failure to rehabilitate so many priests, has been sufficiently emphasized.

Modern Psychology and Priest Sex Abuse

"It is the contention of this essay that there were significant changes in psychological theory as taught in Catholic Universities and practiced in seminary formation programs in the 1950s-1960s, the practical results of which became manifest only after Vatican II. It was, in essence, the acceptance of a new psychological theory that resulted in, on the part of priests, the loosening of the moral restraints on personal behavior, but especially, relative to the current crisis, on genital sexual activity."
