Is Cognitive Change Necessary to Alleviate Symptoms in Patients With Functional Somatic Syndrome?, 2021, Maroti and Johansson

Introduction

What has been included under the umbrella term “Functional somatic syndromes” (FSS) has varied over the years. Diagnoses such as “somatoform” and “somatic symptom disorders,” as well as “medically unexplained symptoms,” have been included in FSS (1). Although there is no complete consensus, FSS usually comprise of conditions such as fibromyalgia, irritable bowel syndrome (IBS), and chronic fatigue syndrome (CFS) (2). A characteristic of FSS is persistent physical symptoms that lead to impairment or disability and that disrupt the capacity to take part in daily life. Although FSS are believed to be caused by a complex interaction of biological and psychosocial factors (3), the conditions are not medically explained in terms of well-Understood or established pathophysiological mechanisms.

Cognitive behavioral therapy (CBT) has become the gold standard psychological treatment for FSS. Several meta-analyses have shown a small to moderate effect in patients with FSS (4–7). Even though the small to moderate effect is robust, in the sense that results have been replicated both within and across conditions, there is limited research on treatment mechanisms (8). That is, CBT has an effect, but why the effect takes place is not firmly established.

Traditional CBT rests on the idea that changing cognitions and behaviors in FSS will decrease somatic symptoms (9). Specifically, changing so-called dysfunctional illness beliefs “are of paramount importance for treatment (success)” (10). According to a review of Windgassen et al. (11), there is a “clear indication” that “cognitive change is important for reducing symptom severity.”

Put simply, a patient who, for example, believes that “something is wrong with my body” or claims a physical attribution such as “I have a chronic infection, that is why I feel fatigued,” will not easily get well. There are some merits to this position. In a review of CBT for IBS, four out of five studies found cognitions to mediate the effect of treatment on symptom severity (11). In another review of CBT for CFS, three different types of illness perceptions (fatigue as something aversive, activity as potentially dangerous to health, and a symptom preoccupation with fatigue) were found to potentially perpetuate CFS symptoms (12).

Although there is a value in the position that changing cognition is of “paramount importance” to reduce symptoms in FSS, we argue that this idea is a simplification and leaves several questions unanswered. In the following, we provide two major arguments against this position.

So much arbitrary causal attribution to unpack. Still can't tell their correlates from their causes.

 

From the discussion section:

This attempt at objective analysis is bizarre given the authors remain oblivious to the design flaws in the research evidence they rely on (ie the use of subjective outcomes in unblinded trials), to the fact that they have no real evidence that what they regard as ‘dysfunctional illness beliefs’ are either dysfunctional or irrational/inaccurate and they display, as @Sean points out, a confusion between association and causality.

If you are building on sand, making your constructions ever more elaborate does not compensate for the lack of any solid foundation.

 

"...fatigue as something aversive"

1) why is this a problematic belief?

2) in my pre-ME life I was very busy, and experienced fatigue; it was no big deal, except when I became hypothyroid, when even walking felt like moving through molasses

3) for me there is a big difference between fatigue from Cross country skiing for hours (pre-ME), and the fatigue with ME

4) and, to correct these researchers, it's not just fatigue!

In my case, as I don't wish to speak for others, it's universal muscle pain, weakness, feeling lightheaded and brain fogged, especially with upright positions, etc., and yes fatigue. A paralyzing kind of fatigue. The kind that takes an act of will to move one's body.

When will this be understood?!

 

This was my dominant symptom for about fifteen to twenty years.

When you are using subjective fatigue as a primary outcome measure its going to be difficult to change. We need objective outcome measures, things that cannot be distorted or fudged.

 

Although these authors do not seem to be up to speed on evidence they do seem to have the right idea in some ways.

They are questioning the validity of the false belief paradigm and the idea that treatment has to address beliefs.

Their final conclusion is pretty sensible:
To establish which mediating variables are of importance, two different treatment protocols with their own distinctive mechanism would ideally be compared.

This is what PACE should have done - compare to different protocols both of which would count as 'active test' treatments but with different putative modes of action. If one worked better than the other then that would hint at mechanism. The problem with PACE was that the two 'active test' treatments were really the same thing under different names, with the same theory behind them. So unsurpisingly there was no difference. And since the other comparison groups were not 'active' controls we don't know if there was any effect at all.

They actually quote some quite useful evidence against the beliefs theories.
Just a pity they had not noticed that CBT doesn't work anyway.

“That is, CBT has an effect, but why the effect takes place is not firmly established”

They just don’t want to admit that their model doesn’t work, it is frequently discussed in psych literature that just the act of sitting down in a room for an hour, therapist qualities and rapport with client (and not doing CBT) with a patient has a treatment effect.

This sounds like a thick blanket of words to cover the sentiment “scr w you”.

 

Nor that the effect is genuinely beneficial, as opposed to it being merely due to a range of known biases and confounders, which are not only typically inadequately controlled for in these kind of studies, but often actively promoted and arbitrarily re-labelled as genuinely beneficial therapeutic effects.

Hard to take seriously any paper which makes this sort of claim.

 

Yes, I worry about anything that mentions alexithymia which is just depression that did not reach a high enough score on the questionnaire!

It is very easy to answer these questionnaires in such a way that they take the physical symptoms of disease as signs of emotional disease. It is difficult to be excited about anything when you are struggling to sit up.

 

Exactly. Its not just ME that needs objective diagnostics, its all of psychiatry as well. At least we have thousands of objective abnormalities in the literature. We just don't understand how it all fits together. Psychiatry has found things in some cases but they still seem to love their questionnaires.

 

See also: "lie detectors". They detect something. It's an actual objective measurement. Does it detect lies or honesty? Of course not. An effect is irrelevant, it's easy to have "an effect". "The book moved on its own" is an effect that can be argued to be a ghost. Means nothing at all, people just want to see what they hope to see and it's sad that in medicine no one seems to care where the psychiatry exemption is applied.

 

It would be great if psychiatry had more objective diagnostics. Unfortunately most are imaging and not sensitive enough to see what pathways are being used. I think I saw one person in 20 years of community psych in NZ that I thought alexithymia met the criteria of being a personality trait i.e. marked dysfunction and was a problem with respect to helping them with their depression. I think the BPS crowd have used this term too loosely and there is no strong evidence for this to be used as a goal of treatment.

 

This is the problem. The brain is a black box and we are still making guesses. Advances in medicine occur with advances in technology. I don't think we yet have the technology to get this right.

The lack of diagnostic tests is only part of the problem. There is too much acceptance that psychiatric hypotheses are proven fact. Not all psychiatrists fall into this trap, and its the same for psychologists and the general public, but far too many either do accept it and/or don't acknowledge the issues.

Diabetes and MS advanced with the right technologies. We made rapid advances in Covid vaccine research because of newer technologies. Lack of the right technologies in psychiatry means nearly all of it is tentative, starting with diagnoses. We need to treat most of it as working hypotheses at best. How can we trust even a pharmacological trial in psychiatry when we cannot be sure what the diagnosis should be? This whole thing is difficult, psychiatry is probably the most difficult area in medicine, but that is no excuse for lax standards or for irrational conduct. Pragmatic compromises are what we can do, but we need to acknowledge the vast scale of uncertainty.

 

If anything it should be the contrary. A lack of hard knowledge should demand much higher standards of safety and caution, much larger margins of error.

One thing psychiatry has proven beyond doubt is how unreliable and potentially dangerous subjective judgements are, no matter how carefully considered and well intentioned. Multiply that by being built on several layers of subjective judgement, and it is a very serious risk to patients.

 

@Sean absolutely.

The point I was heading toward is that you can compensate for uncertainty by adopting both honesty and caution. Acknowledge it, do not lie to patients about it (even a benevolent lie though there are cases where that is in the patient's best interest but it seems far too overused), and most importantly do not hide the issues from other psychiatrists. Indeed, the level of uncertainty can be a barometer for the level of awareness and caution necessary.
