Is the Sonrise approach effective for kids with autism?

Because of the. home-based nature of the program, no published independent study has tested the program's efficacy. A 2003 study revealed that involvement with the program led to more drawbacks than benefits for the involved families over time, though there was a strong correlation between patterns of intervention implementation and outcomes. ABA is the only evidence-based therapy with known efficacy.
Sonrise approach. Anecdotally it seem to be a program that has some merit.
