Yes: We need a new professional standard.
For multiple reasons, psychology and psychiatry cannot dispense with having “some” standard that establishes and limits the scope of its practice and regulates interfaces to physical medicine. This is reality despite the failure of the DSM-5 to meet even minimal standards of intellectual rigor and patient care. Professionals and patients cannot dispense with diagnosis as a step in treatment selection and follow up.
Even recognizing such labels as provisional, to abolish all diagnostic standards would be to open the profession to all manner of quacks and opportunists—almost certainly making things worse.
