Mental Health and Philosophy of Mind

Any literature I've come across on "Mental Health" seems to implicitly assume an internalist philosophy of mind. Has any work been done by externalists on this matter?

It might help if you provide some examples of what you've been reading so we can see what you mean about implicitly assuming internalism.  

Perhaps philosophical discussions specifically around mental illness might seem to imply internalism because mental illness is fundamentally an epistemic disconnect between mental states and facts.  The process of belief formation is itself flawed, so we never even reach the starting point of externalist arguments.
