Arousal reconditioning and delay of satisfaction - offenders can learn to fantasize about appropriate sex objects, change deviant arousal patterns, delay gratification of impulses by learning and assimilating various technuques, so they are less likely to reoffend. Offense chain intervention - offenders can learn relapse prevention techniques including appropriate coping strategies at each stage of the chain, whether or not they admit. They can use other negative behaviors or reaccusation as the end point. Offense cycle intervention - this can apply the same way as with the offense chain in relapse prevention. Problem solving - everyone can increase these skills, which in turn increase available coping skills for all activities when stress or gratification needs are present.
Inappropriate incarceration exacerbates the problem.
Persons who commit sex offenses need sex offense specific treatment so they do not reoffend. If they are incarcerated without treatment, they are likely to come out even worse and more likely to reoffend. Emotionally they will be even more shut down, with lower self esteem, more anger and less coping abilities. We don't know if he did or didn't, but even innocent persons can benefit from this type of cognitive-behavioral treatment. We can all benefit from improved self esteem, better communication, self understanding, increased empathy, etc.
