Studies don't exclude things. They include things.
I think we agree,
Though reported outcomes vary widely,
ranging from about 25 % to 80%, reviews suggest that 60%-80% of adolescents improve during
residential treatment (Curry, 1991; Curtis et al., 2001; Epstein, 2004; Hair, 2005; Wells, 1991).
So you said that "longitudinal clinical studies of residential treatment" has shown 60- 80% success rates.
...
Curry, 1991; Curtis et al., 2001; Epstein, 2004; Hair, 2005; Wells, 1991. Can you provide the text from any of these studies that shows Aspen Education was studied? They clearly don't mention any Aspen programs.
However, Behrens' work is
only about Aspen programs and she concluded that Aspen was
31% successful compared to up to 80% for non-Aspen facilities. Non-Aspen facilities were
two and a half times more successful than Aspen facilities. Wow.
No wonder Whooter doesn't want to talk about Aspen anymore. Now he's advocating non-Aspen facilities! He has converted. It's a miracle.
Whooter now agrees that Aspen has little success compared to others. So little, in fact, that he has abandoned the Behrens study completely! I guess he'll need to find some other Holy Grail for Aspen marketing. This one is destroyed beyond repair.
