Where in the article does it say "NIMH withdraws support for DSM-5"?
KJP was paraphrasing. This statement from that link is not exactly a ringing endorsement of the DSM:
But it is critical to realize that we cannot succeed if we use DSM categories as the “gold standard.” The diagnostic system has to be based on the emerging research data, not on the current symptom-based categories. Imagine deciding that EKGs were not useful because many patients with chest pain did not have EKG changes. That is what we have been doing for decades when we reject a biomarker because it does not detect a DSM category. We need to begin collecting the genetic, imaging, physiologic, and cognitive data to see how all the data – not just the symptoms – cluster and how these clusters relate to treatment response.
I agree that this move is a good thing. The field is too objective as it stands now. A push toward evidence-based medicine will benefit it enormously.
