Physicians may be well equipped for the biological aspects of disease, but not for its psychosocial dimensions, an issue that has been absent in family medicine. The psychosocial aspects of the disease are the factors involved in how patients react to the disease, play a role in the expression of symptoms and disease, and have implications on the lives of patients. Moreover, the biological effects (specific) and psychosocial effects (non-specific) are not simply additive but interactive. Physicians should be aware of this hidden, essentially invisible patient psychosocial morbidity, and must incorporate bio-psychosocial interventions into routine medical care to be more effective. In addition, to consider these aspects in the context of care contributes to the distinctive elements of family medicine.
