The role of psychology in health care delivery.

There is a wealth of professional opportunities for practicing psychologists, particularly given the recent recognition of psychology as a health care profession. A number of dimensions are discussed that can be used as a heuristic to outline the participation of psychologists in the general health care arena. Dimensions include the breadth of disease categories in which psychology has been involved, the involvement of psychologists at different stages of the progression of illnesses, and the diverse roles that psychologists may play in health care. Examples are provided to exemplify the contributions psychologists have made to health care. Recommendations are made to strengthen psychology's role in the health care system. Recent challenges are also reviewed regarding the association of health care and the delivery of services that demand the participation of psychologists.
