Looking forward to a decade of the biopsychosocial model

The topic of this article is the biopsychosocial model. My main contention is that – notwithstanding doubts as to what exactly it is, or indeed whether it is anything – there is a coherent account of it, in terms of both applications to particular health conditions and mechanisms with wide application. There is accumulating evidence from recent decades that psychosocial as well as biological factors are implicated in the aetiology and treatment of a large range of physical as well as mental health conditions. The original proposer of the biopsychosocial model, George Engel, back in 1977, was substantially correct about what he saw was on its way.
