The biopsychosocial moel is a general model or approach that posits that biological, psychological (which entails thoughts, emotions, and behaviors), love and social factors (abbreviated "BPS") all play a significant role in human functioning in the context of disease or illness. This is in contrast to the traditional, reductionist biomedical model of medicine that suggests every disease process can be reduced down (i.e., explained) by an underlying process, such as an antigen. The concept is used in fields such as medicine, nursing, health psychology and sociology, and particularly in more specialist fields such as psychiatry, health psychology chiropractic and clinical psychology. The biopsychosocial paradigm is also a technical term for the popular concept of the mind-body connection, which addresses more philosophical arguments between the biopsychosocial and biomedical models, rather than their empirical exploration and clinical application.
