    The effect seen in PACE is likely an artifact of poor methodology and post-hoc protocol changes, and is comparable in strength to a placebo (the placebo effect size is about 19% for psychological interventions in CFS according to a review by some CBT/GET proponents themselves). The transient nature of this effect and the lack of objective improvements show us that CBT/GET don't even work for a "chronic fatigue" sample. I suspect that a "chronic fatigue" sample is less at risk of GET induced deterioration though.

    This said, I think this is an outstanding article. Some of the confusion and uncertainty surrounding this illness is simply due to bad definitions.

    This paper comes from the ME Biobank team at LSHTM and has been published in the Journal of Health Psychology - which seems to be adopting a helpful and constructive approach to the biomedical model of causation and management of ME/CFS

    There is more to come!

    A nice illustration of how the PACE trial epitomises "a little knowledge is dangerous thing" when the authors are effectively claiming to be the world's leading experts.
