Tipping points in the Department of Defense's experience with psychologists in primary care.

Psychologists played a crucial role in the successful implementation of integrated behavioral health care services in Department of Defense (DoD) primary care clinics. On the front lines of policy development, training programs, clinical care, and program evaluations, psychologists successfully promoted integrated care as a core component of the DoD patient-centered medical home. We review the development of integrated care and discuss the roles of psychologists in the DoD to provide an exemplar of the impact psychologists can have on the implementation and sustainment of integrated care.
