Exploring the ICF: What is a Biopsychosocial Model?

The International Classification of Functioning, Disability and Health (ICF)is a framework for describing and organizing information on functioning and disability.  The ICF is described as a biopsychosocial model of disability;  it simultaneously considers biological factors, psychological factors and societal factors. By incorporating these three factors,  the model is able to create a unique picture of an individual as they manage a health condition.  In contrast, the biomedical model is limited to the biological aspects only.  The biomedical model often overlooks important individual details, increasing chances that therapists and families have a lack of alignment in their goals.

When thinking of a child with hemiplegic cerebral palsy in the biomedical model, we may think of spasticity, range limitation, gait differences, asymmetry in sitting and limited reaching skills.  This may describe any number of children.

In the biospychosocial model we additionally become aware of the environment the person lives in and how it affects their functioning.  Working on the activity of stair climbing is going to hold different importance for a family living on the ground floor versus a family living in an apartment with 18 steps to enter.    Additionally, we are aware of personal factors such extended family help, or access to additional health resources.   We learn about what kinds of ideas and activity motivate each child.   As you can see,  this presents a very unique picture for each individual.

Through curiosity and engagement, there is great depth in each individual when using the biospychosocial model.  Every person is unique.


The  biopsychosocial approach was developed by Dr. George Engel and Dr. John Romano in 1977/1980.

This 2004 article analyzes the biopsychosocial model and how it has developed over the decades.  It describes the evolution of client-centered care.  It also describes the calibration of health care providers in cultivating curiosity, creating trust, recognizing bias, using informed intuition, and communicating clinical evidence while using this approach.
