Sadly, that is specifically what "troubled youth program" means in America. The programs lie to the parents, and the parents usually lie to themselves even if the kids tell them what happened (which they are often forcibly prevented from doing while in the program). These programs have their roots in actual cults, not genuine psychological research.

Other mentioned the Elan School, which is a famous (and typical, unfortunately) example. I cannot emphasize enough how serious the content warnings others have mentioned are. The details can get extremely upsetting.
