Overview
The biopsychosocial model, as expressed in the World Health Organisation’s International Classification of Functioning, Disability and Health (ICF, 2001), attempts to integrate the medical and social models. It frames disability as the result of interactions between biological factors (the person’s body and health condition), psychological factors (their cognition, emotions, and coping), and social/environmental factors (the structures, attitudes, and environments around them).
What it does well
The ICF framework is widely used in clinical and rehabilitation settings. Its emphasis on functioning rather than diagnosis alone can be useful: two people with the same autism diagnosis may have very different functional profiles depending on their environments, supports, and co-occurring conditions. The model’s recognition that context matters, that the same person may function very differently in different settings, aligns well with autistic experience.
Where it falls short
In practice, the biopsychosocial model is often criticised as “the medical model with social garnish.” When clinicians are trained primarily in biomedical frameworks, the “bio” tends to dominate, and the “psycho” and “social” components become afterthoughts. The model can also be used to justify locating the problem back in the individual under the guise of considering “all factors,” particularly when psychological factors are framed as deficits in coping rather than rational responses to hostile environments.
Relationship to autism and neurodivergence
The biopsychosocial model is the stated framework of many autism services, but its application is uneven. At its best, it encourages practitioners to consider the whole person in context. At its worst, it provides a veneer of holism over what remains a deficit-focused, individually-directed approach. Neurodiversity advocates have generally regarded it as an improvement on the pure medical model but insufficient on its own.
