DSM-5 Somatic Symptom Disorders: Differences between second and third draft for CSSD

DSM-5 Somatic Symptom Disorders: Differences between second and third draft for CSSD

Post #168 Shortlink: http://wp.me/pKrrB-27y

A reminder that the third and final DSM-5 comment period closes on June 15 and that I am collating submissions on this site.

Comments are open to professional and lay stakeholders. Please alert clinicians, researchers, allied health professionals, social workers, lawyers, educationalists, therapists, patient advocacy groups to these proposals.

Full proposals, criteria and rationales for the Somatic Symptom Disorders are set out in this post:

DSM-5 proposals for Somatoform Disorders revised on April 27, 2012

According to DSM-5 Task Force Chair, David Kupfer, MD, “After the comment period closes, visitors will no longer be able to submit feedback through the site, and the site will not reflect any further revisions to the draft manual in anticipation of its publication in May 2013. However, the site will remain live and viewable.”

 

Somatic Symptom Disorders Work Group proposals:

Two PDF Disorder Descriptions and Rationale/Validity Propositions PDF documents had accompanied the first and second drafts. There are no revised PDFs reflecting the most recent proposals available on the DSM-5 Development website and the documents published with the second draft have been removed.

I have asked the APA’s Media and Communications Office to clarify whether the Somatic Symptom Disorder Work Group intends to publish revised Disorder Descriptions or Rationale/Validity Propositions documents during the life of the stakeholder review period or whether these documents are being dispensed with for this third draft.

Should updated documents be added to the site during the comment period I will post links.

 

Notes on differences between the second and third draft proposals for CSSD

As with the first and second drafts, the intention remains to rename the Somatoform Disorders section to Somatic Symptom Disorders.

The proposal continues to combine the existing DSM-IV categories:

Somatization Disorder
Hypochondriasis
Undifferentiated Somatoform Disorder
Pain Disorder

into a single new category, Somatic Symptom Disorder.

For the second draft, the work group had suggested two separate diagnoses, Complex Somatic Symptom Disorder CSSD) and Simple Somatic Symptom Disorder (SSSD).

Following evaluation of the results of the DSM-5 field trials, the Somatic Symptom Disorders Work Group has decided that Simple Somatic Symptom Disorder  is “a less severe variant of CSSD.”

The Work Group now proposes merging CSSD and SSSD into a single category called Somatic Symptom Disorder (SSD) and is suggesting dropping the word “Complex” from the category term.

The latest proposed category names for the revision of the DSM-IV’s Somatoform Disorders now look like this:

Somatic Symptom Disorders

J 00 Somatic Symptom Disorder – with the option for specifying:

Mild Somatic Symptom Disorder
Moderate Somatic Symptom Disorder
Severe Somatic Symptom Disorder

J 01 Illness Anxiety Disorder |
J 02 Conversion Disorder (Functional Neurological Symptom Disorder) |
J 03 Psychological Factors Affecting Medical Condition |
J 04 Factitious Disorder |
J 05 Somatic Symptom Disorder Not Elsewhere Classified |

Revised Criteria, Rationale and Severity texts for the above can be found at the links above or on this webpage:

These are the criteria for J00 Somatic Symptom Disorder

J 00 Somatic Symptom Disorder

Updated April-27-2012

Proposed Revision

Somatic Symptom Disorder

Note that the criteria for CSSD in the previous draft, released in May 2011, had read:

“B. Excessive thoughts, feelings, and behaviors related to these somatic symptoms or associated health concerns: At least two of the following must be present.”

But for the third draft, this has been reduced to

“B. Excessive thoughts, feelings, and behaviors related to these somatic symptoms or associated health concerns: At least one of the following must be present.”

This is presumably to accommodate Simple Somatic Symptom Disorder within what had been the criteria for CSSD.

(Last year, for the second draft, the criteria for CSSD had required two from (1), (2) and (3) and a symptom duration of greater than 6 months, whereas the criteria for SSSD had required only one from (1), (2) and (3) and a symptom duration of greater than one month.)

 

Note also that the option for three Severity Specifiers for J00 Somatic Symptom Disorder category: Mild, Moderate, Severe, might potentially be intended to correspond to three newly proposed categories in the ICD-11 Chapter 5: Somatoform Disorders section.

In the ICD-11 Alpha drafting platform (which is a work in progress and comes with caveats), the Somatoform Disorders categories are currently proposed to be renamed to Bodily Distress Disorders. There are three new categories listed:

6R0 Mild bodily distress disorder
6R1 Moderate bodily distress disorder
6R2 Severe bodily distress disorder

These three new category suggestions have no definitions or descriptive parameters visible in the ICD-11 Alpha draft so it isn’t possible to determine at this stage what disorders these newly suggested terms might be intended to capture; nor how they would relate to the existing somatoform disorders categories that still remain listed beneath them in this section of the Alpha draft.

For comparison, this is how the corresponding section of ICD-11 categories currently displays:

ICD-11 Alpha draft:

BODILY DISTRESS DISORDERS [Formerly Somatoform Disorders]

6R0 Mild bodily distress disorder
6R1 Moderate bodily distress disorder
6R2 Severe bodily distress disorder
6R3 Somatization disorder
6R4 Undifferentiated somatoform disorder
6R5 Somatoform autonomic dysfunction
6R6 Persistent somatoform pain disorder
     6R6.1 Persistent somatoform pain disorder
     6R6.2 Chronic pain disorder with somatic and psychological factors [not in ICD-10]
6R7 Other somatoform disorders
6R8 Somatoform disorder, unspecified

Hypochondriacal disorder [ICD-10: F45.2] is currently listed in ICD-11 Chapter 5 as Illness Anxiety Disorder under 6L5 ANXIETY AND FEAR-RELATED DISORDERS > 6L5.6 Illness Anxiety Disorder.

Dissociative (Conversion disorders) [ICD-10: F44] is currently listed in ICD-11 Chapter 5 under Neurotic, stress-related and somatoform disorders > 7A5 Dissociative [conversion] disorders.

There had been discussions by the SSD and Dissociative Disorders work groups for potentially locating Conversion Disorder under the DSM-5 Dissociative Disorders section, for congruency with its location within ICD-10.

For the third draft, it appears that the groups with oversight of the revision of conversion disorder have decided that this category should be renamed to Conversion Disorder (Functional Neurological Symptom Disorder) and classified as a Somatic Symptom Disorder.

In a future post, for ease of comparison, I will post a table comparing DSM-5 third draft proposals with current listings for ICD-11.
