Evidence-based approaches to psychiatric classification are essential to assure the credibility of the field and to conform to current scientific standards. They do, however, have important limitations and are not without their own explicit and implicit set of values. This chapter reviews and describes the origin, background, and goals of the DMS-IV, the principles of evidence-based psychiatry, and how those principles were applied during the DSM-IV process. The limitation of this approach and recommendations and projections for the future are also discussed.
