Well, that's why this study has to be scrutinized. Do you have evidence of those errors in this study?
I haven't fully read the FITNET study yet, but I have spotted an immediately obvious weakness in the methodology, which I'll explain below, at the end of this post.
Like I said before, we have to remain skeptical. But skepticism can be approached from the standpoint of benevolence or malevolence. I think we need to maintain a benevolent skepticism so that we don't throw away potentially useful interventions b/c of preconceived biases. Many people as we see already are conflating web-based CBT with RW (real world) CBT. And that's not even accounting for differences in frequency. So that is a big mistake, imho.
That's a fair opinion to have, but it's not an opinion that I share, based on my understanding of the nature of ME. (See below for more explanation about this.)
Not all of them did GET - only about half, I think - and not all of them even did CBT. Maybe that's a weakness of the study. A follow up study putting web-based CBT up against RW CBT, with a control group who gets no intervention, would be interesting to see, imo.
Yes, they haven't given us a breakdown of the
results for the control groups, as far as I can see.
But some patients received more than one control therapy, so they can't break it down properly anyway.
It would have been interesting, and helpful, if they could have done.
For example, the rehabilitation group might have done exceptionally well, but the GET group might have all deteriorated
drastically. Or the other way around.
(I can't help feeling that they've done this on purpose, to avoid proper analysis.)
57% of participants received more than one treatment.
cognitive behavioural therapy = 66%
rehabilitation treatment = 22%
physical treatment (mostly graded exercise therapy) = 49%
alternative treatment = 24%
Those are all good points, and definitely we should be aware of them and try to analyze the study. Saying it's total BS before we've analyzed it just b/c other studies of Non-web based CBT haven't been successful is a big mistake, I think. I've seen studies that show - whether anyone believes it or not - that the attitude of the physician can even influence the course of ME/CFS in patients. The web-based study seems to take that degree of RW human interaction out of it, so that even non-verbal cues of disapproval, disbelief, etc. on the part of the therapist are minimized or even completely absent. So something as simple as that could be making all the difference between a useless or even harmful intervention and one that could perhaps provide some benefit.
The reason that there is immediate skepticism, dismissal, and even cynicism about this trial is because of the conflict between the reported results and our understanding of the nature of ME.
To illustrate what I mean, for arguements sake, let us assume that there might be different types of Chronic Fatigue, CFS and ME.
To fit the fukuda criteria, you do not
have to have Post Exertional Malaise (is my memory correct there?), so some people would argue that fukuda does not diagnose specifically for a discrete disease known as 'ME', but that it includes people with other types of chronic fatigue, including those with psychological factors.
The fukuda criteria diagnoses CFS, but it does not
specifically diagnose ME, such that the ICC diagnoses. Therefore fukuda possibly diagnoses for a heterogeneous syndrome rather than a distinct disease.
So if we are talking about a version of Chronic Fatigue which might have psychological factors as a cause (a fukuda subset), then yes, maybe CBT might be helpful in those cases.
But if we are talking about a biomedical (neuro-endocrine-immune) disease (a fukuda subset), such as the ICC diagnoses, and such that has been shown to have multiple physical symptoms and signs, then it is preposterous to suggest that 80% of patients would be cured by a simple course of CBT, anymore than 80% of Parkinson's patients would be cured by CBT because it is a neurological disease, not a psychological condition.
The suggestion of a 'cure' or 'recovery' is immediately laughable, hence the immediate cynical reaction. My earlier 'cancer' analogy is appropriate (at least, as it applies to a subset of fukuda CFS patients - e.g. patients who fit the ICC criteria), because cancer and ME (ICC) are both biomedical diseases, and not psychological conditions.
Yes, there are questions to answer in relation to the FITNET trial, such as why the control groups showed such a vastly different response rate, but there might be obvious reasons for this once the trial has been analysed. The results might not have been reported with clarity (i.e. obfuscation), for example, and they might have set up the trial in such a way as to make their online CBT results look favourable. Or, like I said earlier, some or all of the control therapies might simply have been inappropriate or harmful, meaning that the patients had no chance of improving.
But unfortunately, we won't be able to analyse the control groups properly because of the way they have been designed (i.e. each patient received more than one control therapy.)
Unless they used a
neutral intervention, such as relaxation, as a control group, then it isn't really a valid or proper control group. As it was set up, the control group was in fact another 'therapy' group, not a control group.
So I can see immediately that it's a badly designed study because the control therapies are flawed, because they not
neutral interventions. Also, we cannot distinguish between the control therapies. If the authors understood, or cared about, the real nature of ME, then the study would not have been designed with potentially damaging control therapies. We know that activity can be harmful for ME patients, so therapies that involve activity are not appropriate controls. If a control group is, in fact, an 'intervention', then it is not really a control group. The fact that they will not be able to give us the results for each of the control therapies is another weakness of the study. I can't help feeling it was designed this way for purposes of obfuscation.
