The biopsychosocial model (BPS model) or cognitive behavioral model (CBM) looks at biological, psychological and social factors to explain why disorders occur and is a tool used by psychologists to examine how psychological disorders develop.
|“||Exercise or activity programmes are the archetypal BPS intervention. This was shown to us in our trial when we used graded exercise therapy in chronic fatigue syndrome.||”|

BPS model in chronic fatigue syndrome[edit | edit source]
Vercoulen et al (1998) created a highly influential biopsychosocial (BPS)model for "chronic (subjective) fatigue" which was used for myalgic encephalomyelitis/chronic fatigue syndrome, and justified the use of both cognitive behavioral therapy and graded exercise therapy as treatments. However, Vercoulen et al's BPS was developed using patients that did not meet any recognized diagnostic criteria for CFS, instead they selected a mix of patients with idiopathic chronic fatigue and chronic fatigue syndrome; only 68% of these patients experienced post-exertional malaise, which later became regarded as the hallmark symptom of ME/CFS.
Wessely and Harvey (2009) proposed a development of Vercoulen's biopsychosocial model for not only chronic fatigue syndrome, but for all causes of fatigue, including psychiatric disorders, biological illnesses including AIDS, and fatigue without a known cause. Wessely and Harvey's model has been referred to as a psychosocial model. This theoretical model proposed that the all chronic fatigue syndrome and all fatigue was caused by the 3Ps: predisposing factors (e.g. personality traits or other pre-existing risk factors), precipitating factors (e.g. a virus, stress or other trigger) and perpetuating factors (psychological or behavorial factors, e.g., too much rest, being excessively focused on symptoms, beliefs about the illness being caused by a virus, or the patients' other thoughts and behaviors). It did not recognize a genetic predisposition for CFS. 
History[edit | edit source]
In a 1977 article in Science, psychiatrist George L. Engel called for "the need for a new medical model." The BPS model is the dominant model used to understand mental illness and combines biological, psychological and social factors.
Evidence[edit | edit source]
Song and Jason (2005) concluded that their "current investigation found that the Vercoulen et al. model adequately represented chronic fatigue secondary to psychiatric conditions but not CFS."
Criticism[edit | edit source]
Song and Jason (2005) attempted to replicate Vercoulen's model, but found it did not fit patient data.
The BPS model has been criticized for being inappropriately applied to organic biological diseases, and medically unexplained physical symptoms (diseases that cannot yet be fully explained by medical science). Psychologization is the assumption that a disease or illness that cannot yet be explained by medical science must be wholly or partly psychological in nature, and is used to justify psychological treatments such as cognitive behavioral therapy.
BPS models have frequently been applied to ME/CFS, fibromyalgia (FM/FMS), peptic ulcers and other illnesses that are now understood to be physiological diseases. Davey Smith states that peptic ulcer was "the classic BPS disease" but that "Cognitive behavioural therapy rather disturbingly had no effect"; only the discovery of helicobacter pylori in 1983 allowed the patients to be cured.
Controversy[edit | edit source]
The use of the BPS model, and its CBT and GET treatments, in ME/CFS has been heavily criticized by many researchers, charities and patient groups. The BPS model provides the justification for the use of exercise therapy in ME/CFS.
These controversial treatments were used in the PACE trial, which David Tuller, Keith Geraghty, Robert Courtney, Angela Kennedy, Tom Kindlon, Alem Matthees, Mark Vink and many others have exposed the PACE trial as deeply flawed, and potentially fraudulent, and many others have analyzed and reported on the significant harms and ethical issues resulting from the use of CBT or GET in patients with ME/CFS.
The UK Parliament House of Lords PACE Trial debate 6th February 2013 and the UK Parliament Grand Committee Room debate 21st June 2018 debated the PACE trial. Carol Monaghan MP for the Scottish National Party stated at a February 20th debate in the House of Commons Hansard, “I think that when the full details of the trial become known, it will be considered one of the biggest medical scandals of the 21st century.”

cognition Thought processes, including attention, reasoning, and memory.
graded exercise therapy (GET) - A gradual increase in exercise or activity, according to a pre-defined plan. Focuses on overcoming the patient's alleged unhelpful illness beliefs that exertion can exacerbate symptoms, rather than on reversing physical deconditioning. Considered controversial, and possibly harmful, in the treatment or management of ME. One of the treatment arms of the controversial PACE trial.
myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
randomized controlled trial (RCT) - A trial in which participants are randomly assigned to two groups, with one group receiving the treatment being studied and a control or comparison group receiving a sham treatment, placebo, or comparison treatment.
medically unexplained physical symptoms (MUPS) - Technically, this term means that no cause or explanation for the patient's symptoms has yet been found. However, patients diagnosed with "MUPS" are generally lumped into a psychosomatic, or psychologically-caused category by those in the medical profession, without any scientific basis for doing so.
