Restructuring of health care delivery systems has deemphasized tertiary and specialty services with a resultant increase in primary medical care. These reform efforts are anticipated to continue, highlighting the need for rehabilitation psychologists to expand beyond tertiary care settings to sustain the growth and prosperity of their profession. New models of service delivery and training are needed to help them transition into the new health care environment. A recently developed model for integrating behavioral medicine into primary care may serve as a guide. In this paper we discuss a model for integrating behavioral science into the medical management of primary care patients. The model is applicable to the functions and philosophy of rehabilitation psychologists. A discussion of the new model and its relation to rehabilitation psychology is provided along with implications for predoctoral training and strategies for overcoming barriers to primary care integration. © 1997 by the Division of Rehabilitation Psychology of the American Psychological Association.
