In 1994, DSM-IV was published, listing 297 disorders in 886 pages.

The task force was chaired by Allen Frances.

A steering committee of 27 people was introduced, including four psychologists.

The steering committee created 13 work groups of 5 – 16 members.

Each work group had approximately 20 advisers.

The work groups conducted a three-step process.

First, each group conducted an extensive literature review of their diagnoses.

Then they requested data from researchers, conducting analyses to determine which criteria required change, with instructions to be conservative.

Finally, they conducted multicenter field trials relating diagnoses to clinical practice.

A major change from previous versions was the inclusion of a clinical significance criterion to almost half of all the categories, which required symptoms cause " clinically significant distress or impairment in social, occupational, or other important areas of functioning ".

Some personality disorder diagnoses were deleted or moved to the appendix.
