There are lots of places that the three are used interchangeably.
Yes, this is the case, Alex.
But my point was that
I was referring specifically to the use of the term "BDD"
in the context of ICD-11 usage and in the context of the Creed, Gureje 2012 journal paper's usage of "BDD" for ICD-11 and I wanted to be clear about what context you were using it in.
BDD outside of ICD-11 is indeed often used interchangeably with both BDS, and some instances, BSS, notably in New Zealand by Prof Tony Dowell who is on the PCCG workgroup.
He has been pushing the BSS term, already, in presentations, despite the fact that it has no published definition and criteria and no validation.
This is another source of confusion since only BDS has published criteria (Fink et al 2010).
But BDD, as proposed by the WHO's SD3WG in their 2012 paper, had greater congruence with DSM-5's SSD construct than with Fink's BDS.
DSM-5's SSD construct is a divergent construct to BDS (and Fink, Creed and Henningsen have said this in the book they published a couple of years ago on MUS).
So it's a real mess, because as the proposals stood at 2012, it
wasn't the case that the proposed ICD-11 version of BDD was close to Fink's BDS.
It was closer to SSD.
And the PCCG primary care group's BSS was the one that was drew heavily on Fink et al's BDS definition and criteria.
(Except that they tacked on a couple of SSD-like behavioral responses to attempt to accommodate harmonization with SSD.)
So based on the 2012 Creed, Gureje paper you
cannot make the leap from ICD-11's BDD being equal to Fink's BDS.
Because the only elements in its criteria requirement are the presence of persistent preoccupation with
any bodily symptom(s) and several SSD like psychobehavioural responses (which are absent from the Fink BDS criteria). No symptom counts, no body system symptom clusters.
So rather than equate ICD-11's Beta entry, BDD with Fink's BDS, Ms Swift should have been looking at the proposals of the primary care group, about which she had not informed herself.
Also, the wording of the BDD Definition recently added is based on the Creed, Gureje paper. As you'll see from my site.
So I hope Ms Swift now understands that this is a considerably more complex and nuanced issue than her article presented - but the info was there on my site for the taking.
And here's another potential source of confusion.
For the Primary care version of ICD-11 (to be known as ICD-11-PHC), an abridged version of the core ICD-11 classification, there are proposed to be 28 mental health disorder categories.
This is what the PCCG group were proposing for the Primary Care version, in 2012:
Proposed disorders for ICD-11-PHC
Extract: Page 51, Table 2.5
Dysphoric disorders:
[...]
13 Health anxiety
14: PTSD
Body distress disorders:
15 Bodily stress syndrome [Replaces F45 Unexplained somatic symptoms]
16 Acute stress reaction
17 Dissociative disorder
18 Self-harm
[F48 Neurasthenia proposed to be eliminated for ICD11-PHC]
---------
So the PCCG group have been using the term
"Body distress disorders" as a
disorder group section heading, not as a category term. For the category term, they were proposing "Bodily stress syndrome".
Why? My guess is because unless their proposed criteria 100% mirrored Fink's BDS criteria, WHO could not call it BDS. And they certainly could not call it BDS if it included SSD-like behavioural responses as well as the Fink et al BDS requirement for symptom counts and symptom clusters from body systems.
Now that the Lam et al paper is available for free, you will be able to see how similar the BSS construct was in 2012 to BDS model but how they had tacked on some SSD elements. They use some of the wording from the BDS published criteria, including:
"If the symptoms are accounted for by a known physical disease this is not [BSS].”
That is verbatim Fink BDS.
Yeah, I had this presentation on my site last year. This also uses BDD and BDS interchangeably.
The information in Slide 14 was already out of date when the slides were put together. Slide 14 has
Body distress disorders
16 Bodily distress syndrome (new was unexplained somatic complaints)
17 Health preoccupation (new)
18 Conversion disorder (was dissociative disorder)
---------
That was from a 2011 version of the draft for ICD-11-PHC. Prof Goldberg confirmed to me, himself, that by 2012, the list I have pasted in blue above had superseded the list directly above that Feinmann has used. Note also that "Health preoccupation" was superseded by "Illness anxiety" but it is "Health anxiety" that is used in the Lam et al 2012 paper. (In the Beta draft, they are still using
Hypochondriasis but have Illness anxiety as an Inclusion term.)
Why did they change it from "Bodily distress syndrome" to "Bodily stress syndrome"?
Rosendal is on the PCCG group. I suspect that, as I say, ICD-11 could not use the term BDS unless Fink et al gave permission and unless it was a very close mirror of BDS, as the criteria are published.
Read the Lam paper and it is pretty close - but the symptom counts may be different, and because it had SSD like elements, too, it cannot be considered a "pure" or near "pure" Fink BDS construct.
So these are the terms in play:
1.
Somatic symptom disorder (DSM-5's category term, a term which SSD Work Group, Creed, does not like and which WHO in any case could probably not use unless APA were prepared to waive copyright/intellectual property rights on its disorder criteria, out of which it derives income). Published criteria set for SSD, 2013.
2.
Body distress disorders (Primary Care Consultation Group's proposal for a disorder group section name, under which are listed several unrelated disorders.).
3.
Bodily stress syndrome (Primary Care Consultation Group's proposal for a disorder name that in 2012 had much in common with Fink's BDS but with some tacked on elements from SSD, in order to facilitate a degree of "harmonization."). No published and operationalized criteria for BSS.
(But SSD and BDS are divergent constructs - so a mash-up between BSS and SSD is problematic.)
4.
Bodily distress disorder (S3DWG group's preferred disorder name that is entered into the Beta - but in 2012 more like SSD than BDS). No published and operationalized criteria for BDD.
then
5. Fink et al's 2010
"Bodily Distress Syndrome" which
does have published criteria and is
already in use in clinical and research settings in Denmark.
