Until either serious flaws are found in this study, or more studies are done that can refute this one, then the scientific approach is to accept these results, albeit maintaining a healthy skepticism.
Unfortunately, in actual reality, that isn't the scientific method when it comes to psychological treatments for CFS/ME. The PACE Trial has widely been reported as achieving a "30% recovery" rate, but on close inspection we discovered that these results are fatally flawed, incorrect, and misreported. In fact, there was only approx a 13% response rate (a minimum improvement or more, not a "recovery" rate) for CBT or GET, and even this is highly questionable because of the questionable methodology of the study, including the way a "clinically useful" outcome was defined. Also, the actual results are probably even worse when applied to the whole ME patient population because the PACE Trial excluded house-bound and bed-bound patients. But the newspaper headlines reported things along the lines of "ME patients should exercise to the max for best chances of a recovery". Even though the PACE Trial reported that CBT is a "safe" (i.e. 'harmless') therapy, it would be misleading to state that CBT is harmless. The PACE Trial results only apply to a subsection of the CFS/ME patient population, so the results (i.e. that CBT is a 'safe' therapy) cannot be extrapolated to the whole patient population. Also, seeing as many patients report being harmed by CBT in patient surveys, then it doesn't seem sensible to state that CBT is harmless.
There are so many variables in this new FITNET study, that until it is analysed closely, then it shouldn't be taken at face value.
I haven't had time to analyse it yet, so I've used the PACE Trial as an example of why we can't take things at face value.
If kids recover so frequently anyway, for example, then why didn't the kids in the control group recover at a higher rate? They weren't all doing GET. It would be useful to see a similar study in adults, too, of course.
The control group were doing GET, CBT and rehabilitation therapy.
So that may well explain why the control group did so badly. If these therapies aren't administered sensitively to the needs of ME patients, then there may well have been a negative reaction to some or all of the interventions.
As with the PACE Trial, I think they should have included relaxation training sessions for a control group. This seems to me like it's a sensible control group to use for ME patients.
There might also be many other factors in the FITNET study that we aren't aware of yet.
But it would be foolish to simply dismiss the findings out of hand just b/c you have a preconceived notion and don't want to accept that the intervention might have helped.
I don't think that's what's going on here Mr Kite.
I think it's a case of being deeply skeptical, based on many past experiences.
Personally, I think it's dangerous to just accept a study like this without deep skepticism and analysis.
To accept the unlikely notion that CBT 'cures' CFS/ME patients, based on one study that hasn't been properly analysed, is dangerous.
It could be dangerous to those patients being treated (or patients who might be treated in the future based on these results), and it is also more propaganda for psychiatrists that ME is propagated by a maladaptive fear of exercise, and that therefore no funding for the investigation of biomedical causes is needed. In the comment by White and Chalder, they have more or less said that already... Along the lines of: "it doesn't matter what the cause is, as long as we have an effective psychological treatment".
I question that CBT is harmless for children or adolescents. It depends on what form that CBT takes.
If it is a sensible, sensitive and caring form of CBT based on the medical reality of ME, and not on some ideologically-based invented theory about a psychological fear of exercise, then it might be benign.
But if children are told that they have faulty thinking, that their symptoms aren't real, that their feelings do not have any importance or validity, or if there is a suggestion that they are being malingerers or liars, then I think this could lead to all sorts of long-term psychological damage.
Children need support, and validation of their experiences, not undermining.
I'd have to have detailed knowledge of the CBT course before I could come to a conclusion about whether it is harmless or not.
