studies by Simon Wessely and Anthony Cleare
I thought some people might be interested in the following observation.
The KCL have recently published research on XMRV which they clearly got
published very quickly (most likely it was all done in the second half of
2009 or perhaps even the last three months).
This contrasts sharply with another study which found that those who did not respond to CBT had low cortisol. [Ed. Note: i.e., those patients had ME/CFS and not depression misdiagnosed as CFS.]
These results were known in early 2003 (or before) as Anthony Cleare
presented them in Feb 2003 http://www.cdc.gov/cfs/meetings/2003_02.htm :
"Cleare  found that those responders to CBT (43% of the sample at end
of treatment) had baseline urine cortisol levels close to normal whereas
those who did not respond had baseline levels below normal.
This indicates that those who were most impaired on hypothalamic-pituitary-adrenal (HPA) functioning might have been the least able to improve with graded activity interventions.
Clearly, a better understanding of subtypes is needed to determine why only
certain patients benefit from these non-pharmacologic interventions."

practice (e.g. the NICE guidelines), was not published till the middle of

This is despite the fact that another part of this study (it is referenced
in the Roberts (2009) paper as giving further details on the study) was
published back in 2004:

As some people will be aware, people promoting CBT for CFS in the UK have
not been particularly interested in subgroups. CBT is "sold" as being
suitable for all.
If the results that efficacy of CBT might depend on cortisol readings,
clinical practice might be very different now and indeed research might
have moved in a different direction to investigate the different sorts of
