The ‘cognitive behavioural model’ of chronic fatigue syndrome: Critique of a flawed model

Abstract:

Chronic fatigue syndrome/myalgic encephalomyelitis is a debilitating illness that greatly impacts the lives of sufferers. A cognitive behavioural model attempts to explain illness onset and continuance with a hypothesis that the illness is perpetuated by patients’ irrational beliefs and avoidance behaviours. This theory underpins the promotion of cognitive behavioural therapy, a treatment that aims to change beliefs and behaviours. This article reports on a detailed review of the cognitive behavioural model. Our review finds that the model lacks high-quality evidential support, conflicts with accounts given by most patients and fails to account for accumulating biological evidence of pathological and physiological abnormalities found in patients. There is little scientific credibility in the claim that psycho-behavioural therapies are a primary treatment for this illness.

The Importance of Accurate Diagnosis of ME/CFS in Children and Adolescents: A Commentary

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic illness that causes a range of debilitating symptoms. While most research has focused on adults, the illness also presents in children and adolescents. Many physicians find it difficult to diagnose the illness. In this commentary paper, we discuss a range of salient themes that have emerged from our ongoing research into the prevalence of ME/CFS in children and adolescents.

We discuss reasons why pediatric prevalence estimates vary widely in the literature, from almost 0% to as high as 3%. We argue that there is considerable misdiagnosis of pediatric cases and over-inflation of estimates of pediatric ME/CFS. Many children and teenagers with general fatigue and other medical complaints may meet loose diagnostic criteria for ME/CFS. We make recommendations for improving epidemiological research and identifying pediatric ME/CFS in clinical practice.

Are ME/CFS Patient Organizations “Militant”?

Abstract:

Myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS) is a contested illness category. This paper investigates the common claim that patients with ME/CFS—and by extension, ME/CFS patient organizations (POs)—exhibit “militant” social and political tendencies. The paper opens with a history of the protracted scientific disagreement over ME/CFS. We observe that ME/CFS POs, medical doctors, and medical researchers exhibit clear differences in opinion over how to conceptualize this illness.

However, we identify a common trope in the discourse over ME/CFS: the claim of “militant” patient activism. Scrutinizing this charge, we find no compelling evidence that the vast majority of patients with ME/CFS, or the POs representing them, have adopted any such militant political policies or behaviours. Instead, we observe key strategic similarities between ME/CFS POs in the United Kingdom and the AIDs activist organizations of the mid-1980s in the United States which sought to engage scientists using the platform of public activism and via scientific publications.

Finally, we explore the contours of disagreement between POs and the medical community by drawing on the concept of epistemic injustice. We find that widespread negative stereotyping of patients and the marginalization and exclusion of patient voices by medical authorities provides a better explanation for expressions of frustration among patients with ME/CFS.

Myalgic encephalomyelitis/chronic fatigue syndrome and the biopsychosocial model: a review of patient harm and distress in the medical encounter

Methods: A narrative review methodology is employed to synthesize the evidence for potential iatrogenesis.

Results: We identify seven potential modalities of iatrogenesis or harm reported by patients:

  1. difficulties in reaching an acceptable diagnosis;

  2. misdiagnosis, including of other medical and psychological conditions;

  3. difficulties in accessing the sick role, medical care and social support;

  4. high levels of patient dissatisfaction with the quality of medical care;

  5. negative responses to controversial therapies (cognitive behavioral therapy and graded exercise therapy);

  6. challenges to the patient narrative and experience;

  7. psychological harm (individual and collective distress).

Conclusion: The biopsychosocial framework currently applied to ME/CFS is too narrow in focus and fails to adequately incorporate the patient narrative. Misdiagnosis, conflict, and harm are observable outcomes where doctors’ and patients’ perspectives remain incongruent. Biopsychosocial practices should be scrutinized for potential harms. Clinicians should consider adopting alternative patient-centred approaches.

  • Implications for rehabilitation
  • Patients with ME/CFS may report or experience one or more of the modalities of harms and distress identified in this review.

  • It is important health and rehabilitation professionals seek to avoid and minimize harms when treating or assisting ME/CFS patients.

  • There are conflicting models of ME/CFS; we highlight two divergent models, a biopsychosocial model and a biomedical model that is preferred by patients.

  • The ‘biopsychosocial framework’ applied in clinical practice promotes treatments such as cognitive behavioral therapy and exercise therapy, however, the evidence for their success is contested and many patients reject the notion their illness is perpetuated by dysfunctional beliefs, personality traits, or behaviors.

  • Health professionals may avoid conflict and harm causation in ME/CFS by adopting more concordant ‘patient-centred’ approaches that give greater prominence to the patient narrative and experience of illness.

Rethinking the treatment of chronic fatigue syndrome—a reanalysis and evaluation of findings from a recent major trial of graded exercise and CBT

Abstract:

Background: The PACE trial was a well-powered randomised trial designed to examine the efficacy of graded exercise therapy (GET) and cognitive behavioural therapy (CBT) for chronic fatigue syndrome. Reports concluded that both treatments were moderately effective, each leading to recovery in over a fifth of patients. However, the reported analyses did not consistently follow the procedures set out in the published protocol, and it is unclear whether the conclusions are fully justified by the evidence.

Methods: Here, we present results based on the original protocol-specified procedures. Data from a recent Freedom of Information request enabled us to closely approximate these procedures. We also evaluate the conclusions from the trial as a whole.

Results: On the original protocol-specified primary outcome measure – overall improvement rates – there was a significant effect of treatment group. However, the groups receiving CBT or GET did not significantly outperform the Control group after correcting for the number of comparisons specified in the trial protocol. Also, rates of recovery were consistently low and not significantly different across treatment groups. Finally, on secondary measures, significant effects were almost entirely confined to self-report measures. These effects did not endure beyond two years.

Conclusions: These findings raise serious concerns about the robustness of the claims made about the efficacy of CBT and GET. The modest treatment effects obtained on self-report measures in the PACE trial do not exceed what could be reasonably accounted for by participant reporting biases.

Myalgic encephalomyelitis/chronic fatigue syndrome patients’ reports of symptom changes following cognitive behavioural therapy, graded exercise therapy and pacing treatments: Analysis of a primary survey compared with secondary surveys

Abstract:

Cognitive behavioural therapy and graded exercise therapy are promoted as evidence-based treatments for myalgic encephalomyelitis/chronic fatigue syndrome. This article explores patients’ symptom responses following these treatments versus pacing therapy, an approach favoured by many sufferers. We analyse data from a large cross-sectional patient survey ( n = 1428) and compare our findings with those from comparable patient surveys ( n = 16,665), using a mix of descriptive statistics and regression analysis modelling.

Findings from analysis of primary and secondary surveys suggest that cognitive behavioural therapy is of benefit to a small percentage of patients (8%-35%), graded exercise therapy brings about large negative responses in patients (54%-74%), while pacing is the most favoured treatment with the lowest negative response rate and the highest reported benefit (44%-82%).

Further commentary on the PACE trial: Biased methods and unreliable outcomes

Abstract:

Geraghty in the year 2016, outlines a range of controversies surrounding publication of results from the PACE trial and discusses a freedom of information case brought by a patient refused access to data from the trial. The PACE authors offer a response, writing ‘Dr Geraghty’s views are based on misunderstandings and misrepresentations of the PACE trial’. This article draws on expert commentaries to further detail the critical methodological failures and biases identified in the PACE trial, which undermine the reliability and credibility of the major findings to emerge from this trial.

Epistemic injustice in healthcare encounters: evidence from chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) remains a controversial illness category. This paper surveys the state of knowledge and attitudes about this illness and proposes that epistemic concerns about the testimonial credibility of patients can be articulated using Miranda Fricker’s concept of epistemic injustice. While there is consensus within mainstream medical guidelines that there is no known cause of CFS/ME, there is continued debate about how best to conceive of CFS/ME, including disagreement about how to interpret clinical studies of treatments.

Against this background, robust qualitative and quantitative research from a range of countries has found that many doctors (and medical students) display uncertainty about whether CFS/ME is real, which may result in delays in diagnosis and treatment for patients. Strikingly, qualitative research evinces that patients with CFS/ME often experience suspicion by healthcare professionals, and many patients vocally oppose the effectiveness, and the conceptualisation, of their illness as psychologically treatable.

We address the intersection of these issues and healthcare ethics, and claim that this state of affairs can be explained as a case of epistemic injustice (2007). We find evidence that healthcare consultations are fora where patients with CFS/ME may be particularly vulnerable to epistemic injustice. We argue that the (often unintentional) marginalisation of many patients is a professional failure that may lead to further ethical and practical consequences both for progressive research into CFS/ME, and for ethical care and delivery of current treatments among individuals suffering from this debilitating illness.

‘PACE-Gate’: When clinical trial evidence meets open data access

Abstract:

Science is not always plain sailing and sometimes the voyage is across an angry sea. A recent clinical trial of treatments for chronic fatigue syndrome (the PACE trial) has whipped up a storm of controversy. Patients claim the lead authors overstated the effectiveness of cognitive behavioural therapy and graded exercise therapy by lowering the thresholds they used to determine improvement. In this extraordinary case, patients discovered that the treatments tested had much lower efficacy after an information tribunal ordered the release of data from the PACE trial to a patient who had requested access using a freedom of information request.
