What is the progress on moving away from the DSM? [1] "NIMH funding to shift away from DSM categories" From that article it sounds like their are a number of people and groups that can't agree on the value of DSM categories but they will continue to use it. Was it sunk cost? Fear of admitting mistakes leading to malpractice? Numerous categories have been removed throughout the revisions. I recall they created some controversy when removing homosexuality as a disorder. What scientific methods are used to add, change or deprecate a category?
