> The article you linked to talks about psychiatry (the DSM is tightly bound to psychiatry, not psychology).

Not so. The DSM is the central authority and diagnostic manual for both psychiatry and clinical psychology. Reference:

> I don't know if you meant by including that link that psychologists criticising psychiatrists undermines their credibility ...

I included the link only to show that the DSM is being abandoned by mental health professionals, not to suggest a schism between psychiatry and psychology. The latter has been true for decades and goes without saying.
