What edition is the DSM-IV-TR of the Diagnostic and Statistical Manual of Mental Disorders?

The DSM-IV-TR stands for the Fourth Edition, Text Revision of the Diagnostic and Statistical Manual of Mental Disorders. This specific edition is an updated version of the DSM-IV, which was initially published in 1994. The "Text Revision" part indicates that it includes revised text and updated information, but it does not change the organization of the major diagnostic criteria from the fourth edition.

This edition serves an essential role in the field of mental health by providing standardized criteria for classifying and diagnosing mental disorders, which is crucial for effective treatment planning and research. It reflects improvements and updates in understanding mental disorders based on evolving clinical knowledge and research findings up until its publication. Thus, identifying it as the Fourth Edition, Text Revision is accurate because it acknowledges both the base edition and the revisions made thereafter.
