Healthcare and the biopsychosocial and biomedical models

             Discuss why a modern healthcare system should adopt a biopsychosocial rather than a biomedical approach
             The biomedical approach is the dominant model in medicine today and it has guided the thinking of most health practitioners for hundreds of years (Taylor,1986).

Many books in health psychology use the analogy of a mechanic repairing a car. He or she would diagnose a problem and then carry out repairs accordingly.

In 1900 the three most common causes of death were influenza and pneumonia, tuberculosis and gastro-enteritis. All these are caused by micro-orga...
