Last fall, Professor Sir Simon Wessely and Professor Trudie Chalder were among several co-authors of a study published in the Journal of the Royal Society of Medicine. The study purported to prove that years of provision of cognitive behavior therapy (CBT) to patients with “chronic fatigue” and “chronic fatigue syndrome” proved that the intervention was a success. I previously pointed out myriad problem in this post last August.
The paper read as if it were meant to shore up support for CBT during the deliberations of the National Institute for Health and Care Excellence over the new ME/CFS guidelines. The draft guidance, which dropped the recommendation for CBT designed to cure the illness, was published in November, with a final version due in April.
