Maybe it’s because they are a generic/vague fatigue organisation rather than a specificallyM.E. one? Chronic fatigue is a dust bin diagnosis convering many illnesses that have fatigue as a feature, and it can include psychogenic fatigue which responds positively to CBT/GET. Until ME and CF/CFS are adequately separated and heterogenous dust bin disgnosis fatigue patients excluded from ‘ME trials’ we are doomed to get spurious results
I think there's a lot of truth in that. After all, they supported the PACE trial that used the Oxford definition of 6 months fatigue.
Perhaps we should ask Action for M.E. to change its name to action for chronic fatigue. I have no idea why the acronym AfCF suddenly made me think 'covfefe'
