DSM 5 Changes: How the DSM 5 compares to the DSM IV

By Amanda Rowan on June 19, 2014

What’s new in the field of mental health? The DSM 5! And while we all transition from the DSM IV to the DSM 5, it is good to take a look at what has changed. If you are preparing for the Social Work Exams or MFT Exams, the ASWB, the BBS, and the AAMTRB have all announced that the DSM 5 will not be tested until 2015.

DMS5_vs_DSM_IV

Published in May of 2013, the DSM 5 was a 15-year work in progress. Overall, the DSM 5 is not very different from the DSM IV. If you compared the two, like I have done, I think it is safe to say that most of it is the same and about 10% is different. The changes that were made were both major and minor.

The major changes are:

  • The elimination of the multiaxial system (goodbye “the client is axis II” references)
  • The organization of the different groupings of related disorders (for example, the creation of Trauma- and Stress- Related Disorders category)
  • Switching from Roman Numerals to numbers (IV to 5 instead of V)

The minor changes include:

  • New diagnoses that did not appear in DSM IV
  • Changing the name of DSM IV diagnoses
  • Changing the criteria of DSM IV diagnoses

Let’s start with the 11 new DSM V diagnoses:

1) Social (Pragmatic) Communication Disorder: Defined by Impairments in the use of conversation. Use of vocabulary and sentence structure is intact, onset early childhood.

2) Catatonia Due to Another Medical Condition: Defined by cataplexy, waxy flexibility, stupor, agitation, mutism, negativism, posturing, mannerisms, stereotypies, grimacing, echolalia or echopraxia due to medical condition.
