Biopsychosocial model

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

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.[1][2]


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.[3]

BPS model in chronic fatigue syndrome[edit | edit source]

The biopsychosocial model for ME/CFS by Vercoulen et al (1998).
Fatigue: the subjective feeling of fatigue; fatigue subscale of the Checklist Individual Strength. Focusing on (Bodily) Symptoms: somatisation subscale of the Symptom Checklist. (Level of) Physical Activity: Sickness Impact Profile (SIP) subscale mobility (SIP-MOB) and the Physical Activities Rating Scale. (Functional) Impairment: impairment in daily life; subscale of activities at home of the SIP. Sense of Control (over Symptoms): selected items of the modified Pain Cognition List on a specific five-point scale. Causal Attributions: Causal Attributions List (high scores: physical attributions, low scores: psychosocial attributions).

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.[4][5] 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;[4] only 68% of these patients experienced post-exertional malaise, which later became regarded as the hallmark symptom of ME/CFS.[4]

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.[6] Wessely and Harvey's model has been referred to as a psychosocial model.[6][5] 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. [5]

History[edit | edit source]

In a 1977 article in Science,[7] 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.[8]

Thoughts, beliefs and a lack of activity cannot explain Chronic Fatigue Syndrome

Vercoulen et al. (1998) suggested their findings indicated that individuals with CFS attribute their symptoms to physical causes, are overly preoccupied by physical limitations, and do not maintain regular activity. According to this model, these factors cause individuals with CFS to be functionally impaired and to experience severe fatigue. The fact that this model could not be replicated with either the CFS or those with medical reasons for their chronic fatigue... suggests an important distinction between individuals with chronic fatigue due to a psychiatric condition versus CFS. In other words, the present study does not support a purely psychogenic explanation for CFS.

Song and Jason (2005)


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 partlypsychological 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.[3] Davey Smith states that peptic ulcer was "the classic BPS disease" but that "cognitive behavioral therapy rather disturbingly had no effect"; only the discovery of helicobacter pylori in 1983 allowed the patients to be cured.[3]

The application of the BPS model for ME/CFS has led to graded exercise therapy (GET or GES) and cognitive behavioral therapy (CBT) as treatment for ME/CFS in a number of countries including the UK.

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.[9][10] The BPS model provides the justification for the use of exercise therapy in ME/CFS.[3]

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.[11][12][9][13][14][2]

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.”[15][16]
