    The link works for me. Try copying and pasting it into your URL bar/field.

    "CBT and GET were based on a hypothetical model of chronic fatigue syndrome whereby symptoms and disability are assumed to be primarily perpetuated by a fear of symptoms and activity, avoidance of activity, and associated deconditioning (lack of fitness). CBT and GET were intended to address these assumed perpetuating factors and to “reverse”2 the illness, leading to “an increase in activity capacity” and ultimately a recovery. CBT mainly focused on addressing fear and avoidance, and GET on reversing deconditioning. The trial's manual for therapists explains the model of illness for GET: “Participants are encouraged to see symptoms as temporary and reversible, as a result of their current physical weakness, and not as signs of progressive pathology”.1, 2

    In the latest analysis of the PACE trial in The Lancet Psychiatry (February, 2015),3 Trudie Chalder and colleagues explain that CBT and GET did not improve the assumed lack of fitness, as assessed via a step test, and that “fitness measures do not appear to mediate the effects of either treatment”. Chalder and colleagues acknowledge that the trial outcomes do not support the hypothetical deconditioning model of GET for chronic fatigue syndrome."

    "The PACE trial is to our knowledge the largest investigation of CBT and GET for chronic fatigue syndrome to date. The deconditioning hypothesis was not supported, and the fear-avoidance hypothesis was not supported by the trial's objective outcomes. These factors, along with the disappointing self-report clinical response rates for CBT and GET in an open-label trial, cast substantial doubt over the validity of the fear-avoidance and deconditioning hypothesis for chronic fatigue syndrome."

    I find the references section particularly interesting.

    That's a letter to the editor, not an article. See the "Correspondence" right over the title. If you look at the current issue, you can see the Articles section long after the Correspondence section.

    Ah, they fooled me. I saw the Previous Article and Next Article buttons and assumed this piece in between was also an article. Silly me.

    Good letter anyway. Well written and concise.

    I'm still astonished that The Lancet, of all journals, published this letter instead of trashing it the moment they got it. I consider this progress.

    Credit where due. A number of letters from patients have been formally published by various journals, including The Lancet for the original PACE paper (2011).

    Begrudgingly at times, sure, but they did publish them.

    They always respond to anything that threatens their narrative, just with more incestuous papers praising the effectiveness of CBT and GET.

    I've realised I shouldn't have used the word "campaigning" with regard to Robert Courtney (my apologies).

    As I recall, the surmised existence of "a campaign" was successfully used as grounds for the denial of a Freedom of Information request re PACE.

    I should have said that Robert Courtney has previously raised valid questions about the PACE trial and the conclusions drawn from it. Which he has.

    Seems like the BPS bunker is gonna stick with their faulty illness beliefs for a while longer... Letting go is hard, I get that. Nothing that a lil' CBT couldn't fix though! Just gra-dual-ly let go... :rolleyes:

    Lol!!! how is that science in any way, shape or form? They are literally saying that they are not interested in 'objective outcomes'. What a load of jokers they are!!!

    (In case anyone missed it)
    The journalist, David Tuller DrPH, has today posted a substantial piece on the PACE Trial:

    TRIAL BY ERROR: The Troubling Case of the PACE Chronic Fatigue Syndrome Study
    http://www.virology.ws/2015/10/21/trial-by-error-i/

    There's an introduction and summary at the start if you don't want to take on the whole thing.

    It's being discussed in this PR thread:
    http://forums.phoenixrising.me/inde...he-pace-chronic-fatigue-syndrome-study.40664/

    ME Network have also posted their own summary piece:
