Are we using the best diagnoses to make progress in psychiatric research? In the current issue of JAMA Psychiatry, we ask whether dimensional diagnoses should replace categorical diagnoses. Yee and coauthors1 argue in favor of such a change, and Weinberger and coauthors2 argue against it. Our statistical editor, Helena Chmura Kraemer, PhD, reflects on this debate.3 These invited articles were stimulated by the decision of the National Institute of Mental Health to focus psychiatric research on the Research Domain Criteria (RDoC), a new nosology for psychiatric disorders.
