In anticipation of the fact that the next major revision of Diagnostic and Statistical Manual of Mental Disorders (DSM) would not be published until at least 16 years after DSM-IV, a text revision of DSM-IV was published in 2000. The primary goal of this document, titled DSM-IV-TR, was to maintain the currency of the DSM-IV text, which reflected the empirical literature up to 1992. Most of the major changes were confined to the descriptive text. Changes were made to a handful of criteria sets in order to correct errors found in DSM-IV. In addition, some of the diagnostic codes were changed to reflect updates to the International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) coding system adopted by the U.S. government.
