The Association for Science in Autism Treatment (ASAT) has just added a section in which summaries of the research support for a variety of treatments are available. They are written in a brief format and are intended to be a useful source for those looking for guidance on what the research literature has to say about science in autism treatment.
They can be accessed at:
