An SLP that I've used for a number of years integrated ToM methods in her teaching of my, now, 13 y/o son. The basis for integrating it was the thought that those on the spectrum are unable to attribute mental states to others, or have a deficit in ToM. That is, individuals who experience a ToM deficit have difficulty determining the intentions of others, have a lack understanding of how their behavior affects others, and have a difficult time with social reciprocity.
While it's interesting to ponder the ramifications from a philosophical perspective, I ultimately decided that it would take a well-experienced psychologist to use it as a tool to help those on the spectrum, and it isn't something a young woman with a Master's degree in speech language pathology should be tinkering with. It seemed too easy to introduce concepts that would result in a schizoid personality.
As a disclaimer, I've taking only one psychology course in my life, and although I dated a psychologist for several years and heard her strong defense of psychology as a hard science, I remain very skeptical.

Anything from Simon Baron-Cohen I would recommend. He has some great books on Theory of Mind. Also I use comic strip conversations by Carol Gray with my daughter in this area. It's a great tool.
