The biopsychosocial model purportedly acknowledges biological, psychological and social factors in health and illness. However, contrary to the biopsychosocial model envisaged by Engel, the biopsychosocial model as applied to ‘medically unexplained symptoms’ and to many chronic illnesses and disabilities is not about a more holistic and person-centred form of healthcare. Neither is it about overcoming mind-body dualism. Rather, biopsychosocial hegemony is driven by political and economic agendas, bound up with the professional and financial interests of many of those who most strongly advocate this model. It is also a form of hegemony which, despite its rhetoric, is based on very little empirical underpinning. This category of blogs seeks to highlight these agendas and interests.
