The evidence is simply the results we saw in our own kids. Does it work for everyone? NO. Are the programs perfect? NO Did I disagree with some of it? YES Is my kid doing a lot better than he was before the program? Absolutely.
This isn't faith- it's evidence.
When a parent puts a kid in an emotional growth program the parent clearly understands that there is no guarantee that it will help the kid. You are willing to give it a try, because there are no other options left and the teen can no longer live in your house or in your community. In the case of programs like Carlbrook, your child is safe, eating well, getting a solid education and, hopefully, benefitting from therapy and interaction with peers who face similar struggles.
Like I said- your irrational hatred of programs like Carlbrook and parents who try them is very suspect. Religious right all over again.
