There are hundreds of programs in the current corrections system like this being used today.
Very few if any of them actually work.
In order to rehabilitate ANYONE for ANYTHING (criminal lifestyle, drug habit, etc), the person has to WANT to rehabilitate, they have to want to make a change. You can't "brainwash" them by "coaching" them into making better choices.
The problem comes when the person is released and returns to the same environment they were in when they left. Thus my mention of funding to move people to another location and get them a job, etc.
You can't FORCE someone to rehabilitate. Just like forcing someone to see a psychologist does nothing for them, as the psychologist merely assists someone with figuring out their problems rather than doing it for them, but those who willingly go and do it for the right reasons will usually find results.
So your 25% less repeat offenders "study" is merely pointing out that the methods of rehabilitation assisted more with helping those who already wanted to make a change. I will give your study that much credit. And to an extent the first line of "rehabilitative" programs aims to do that too. That would be called probation. As im certain you know probation comes with suspending a sentence and requiring someone to meet certain conditions based upon the circumstances involving the specific offense to which the subject has been found guilty of.
Unfortunately the vast majority of repeat offenders are beyond rehabilitation because they do not care nor desire to make a change in their lifestyle. And should that day come when a repeat offender decides he/she wants to make a change, they will seek the help they need either while still incarcerated or after their release.
And it usually involves a change in environment.
