essay in The Lancet Psychiatry entitled 'In defence of the biopsychosocial model'. Progress does need to be made on clarifying George Engel's biopsychosocial model (see previous post).
Engel’s model promotes a holistic psychiatry in the same way as critical psychiatry and is a challenge to biomedical dogmatism. His original Science paper was written in response to a paper published in JAMA
by Arnold Ludwig (1975) called ‘The psychiatrist as physician’.
Ludwig was concerned about the state of psychiatry, which he saw as under attack from what we now identify as 'anti-psychiatry'. His response was to accept that modern-day psychiatry is vulnerable to such charges. His solution was to retreat to the medical model. As far as Ludwig was concerned, psychiatry should deal with
medical illness, including neuropsychiatric and medicopsychiatric disorders,
rather than nonpsychiatric problems, which are more appropriately handled by
nonmedical professionals. This position is what has more recently been called a 'remedicalised psychiatry' (see previous post). Ludwig was clear that psychiatry's viability
was dependent on an understanding of mental illness as due to known, suggestive
or presumed brain dysfunction. Interestingly, he predicted, “I am not
optimistic that there will be any sudden and dramatic resolution of these
issues” (p. 604). Subsequent history could be said to have proved him wrong in
the sense that psychiatry has become more biomedical since the publication of
DSM-III in 1980 and the development of brain imaging. Modern psychiatry has become more biomedical than even Ludwig anticipated.
Engel, by contrast, was not happy with
Ludwig's proposal for change. As far as he was concerned, all medicine, not
just psychiatry, was in crisis. He believed doctors had become
insensitive to the personal problems of patients and preoccupied with procedures.
In short, medicine is too disease-oriented rather than patient-orientated. For
Engel, the biopsychosocial model has real advantages, by taking account of
cultural, social and psychological considerations as well as biological.
Furthermore, it avoids the polarisation between biomedical reductionists,
amongst which Engel would have included Ludwig, and exclusionists, like Thomas
Szasz, who deny mental illness. Szasz, in fact, had the same biomedical
understanding as reductionists of the nature of illness as physical lesion, but
did not believe in mental illness because a biological basis has not been
established. I have always tried to be clear that there are aspects of Szasz's views which do not coincide with my views about critical psychiatry (eg. see previous post). My views are more identified with Engel's.
What is of interest is that both Ludwig and Engel were trying to salvage
psychiatry in the context of ‘anti-psychiatry’. This is why this situation is
relevant to critical psychiatry, which has its origins in anti-psychiatry
(see my book chapter). I am suggesting that Engel’s
biopsychosocial model is a viable form of critical psychiatry.
Many psychiatrists, like Linda in her essay, would say that their approach to psychiatry is biopsychosocial, taking into account psychosocial factors as well as biological. I agree that most psychiatrists are pragmatic in their approach. However, even though most psychiatrists are not narrowly biomedical, they are still biomedical (see previous post), in the sense that they generally believe that mental illness, or at least major mental illness, such as schizophrenia and bipolar I disorder, is due to brain abnormalities, even though the evidence is against this conjecture. More than the empirical evidence, the philosophical argument about the relationship between mind and body is against such speculation. Psychiatrists now rarely become involved in this conceptual debate because they expect that brain research will find the solution to mental illness.
As pointed out by Linda, the biopsychosocial model has been critiqued as being too eclectic by Nassir Ghaemi, leaving psychiatry with no overall theoretical structure as "all theories are possible and all perspectives are valued" (p.1) (see my book review). I agree that psychiatry can be eclectic with, for example, biological and psychotherapeutic treatments being combined without any systematic theory to support such a therapeutic strategy. There is also commonly a split in the aetiological understanding of mental illness, with major psychotic illness being seen as biological in origin, and more minor, neurotic illness seen as having psychosocial causes.
The real origin of eclecticism in modern psychiatry, though, is not in the biopsychosocial model but in the mainstream response to ‘anti-psychiatry’. Anthony Clare’s Psychiatry in dissent, mentioned by Linda, was a response to anti-psychiatry (see previous post). It eschewed a well-defined theoretical basis for practice. In this way, Clare avoided the worst excesses of reductionism and the objectification of patients that caused particular concern to anti-psychiatry. This approach is what is now often labelled as ‘biopsychosocial’ and I worry that Linda is using the term in this way. Most psychiatry is only semi-critical in this sense (see previous post). The true meaning and implications of Engel’s biopsychosocial model have been diluted.

Defending Engel's biopsychosocial model
Subscribe to: Post Comments (Atom)
Interesting blog Duncan...but what do you think is the true meaning and implications of Engel’s biopsychosocial model?
Peter Fonagy who promotes the importance of a spread childhood relationships in developing mental health does not seem to have kept up with the changing nature of family and friendship groups in society. Richard Bowlby attaches great importance to the effect of close families celebrating the fact that his son and family choose to live within 20 mins of him and his wife. Some in positions of influence are too effected by their own experiences which in turn effect the theories they are attracted to - which wouldn't be too important if they were not in positions to attract followers and huge amounts of funding which are used to promote a personally favoured theory over others. Peter F is not a great fan of neuropsychology which misses the human dimension of being, yet he is a supporter of the existence of genes for certain vulnerabilities -his own being robust enough to enable a rise to the top - yet genes are mutable. Society is being used as a collective guinea pig providing rewarding careers for some but with very little benefit to those who are in need of being helped as human beings rather than drug depositories, So some want to scan people's brains, others investigate our genes - the ones who decide what research is carried out are from advantaged backgrounds with the education, nepotism and cronyism that supports them - well that will sort the wheat from the chaff then. Who will be the ones having their brains and their genes tweaked...'the public 'in general have no idea what the agenda is and no say in it whether social psychological or biologically engineered. susanne
Thanks for your comment, Helen. Sorry if my post may seem to have been cut off short. Perhaps I need to do another post to clarify what I mean about the ideological implications of critical psychiatry.
Essentially, I have always argued that critical psychiatry is primarily about not seeing functional mental illness as due to brain disease. Similarly, Engel in his Science paper sees psychiatry’s basic fault as being “adherence to a model of disease”. I’ve said before in a previous post that more needs to be made of the DCP position on this (see http://criticalpsychiatry.blogspot.com/2017/07/giving-up-disease-model-of-mental.html)
'...most psychiatrists are...biomedical...in the sense that they generally believe that mental illness, or at least major mental illness, such as schizophrenia and bipolar I disorder, is due to brain abnormalities, even though the evidence is against this conjecture.'
Don't most ordinary UK psychiatrists acknowledge that psychosocial stressors (including trauma and abuse) may be more important causal factors in many/most individual patients but they can only address those stressors with the limited human resources they (or their CMHT team manager) have at their disposal?
Why those human resources are 'limited' would seem to be a more pressing issue for someone who foregrounds the 'Politics of Mental Health' on their Twitter profile (@HSpandler) rather than the academic and abstruse 'true meaning and implications of Engel’s biopsychosocial model'.
Some followers of Duncan's Blog may have already seen my recent critique of the more prominent 'Critical Psychiatrists' and 'Critical Psychologists', which focuses on Mental Health funding: https://drnmblog.wordpress.com/2018/05/23/how-drop-the-disorder-colludes-with-the-neoliberalism-it-claims-to-oppose/
