Psychologists have an unprecedented opportunity to influence primary medical care systems where chronic conditions, somatic symptoms, and health-threatening behaviors are prevalent. The authors developed a new model to incorporate behavioral medicine expertise into existing primary care practice with the purpose of delivering integrated, comprehensive, and efficient health care through physician training and direct patient care services. This model moves psychologists from isolated referral settings to the front line of medical care, where a broader impact on the outcomes and costs of health care can be achieved.
