How does the number of disorders listed in DSM-5 compare with the number listed in DSM-IV?

1. The count of diagnosable conditions grew steadily across the early editions of the manual. 2. DSM-I listed 106 diagnoses in 130 pages, and DSM-III listed 265 diagnoses in 886 pages. 3. DSM-IV listed 297 disorders, and DSM-5 lists 237, so the count fell even though the volume grew longer. 4. Reading the change as a rise inverts the two figures, which is the trap set by the growth of the page count. 5. The figure 265 belongs to DSM-III and 106 to DSM-I, so neither describes the most recent change. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 15 "Psychological Disorders", section 15.2 Diagnosing and Classifying Psychological Disorders_
