Increasing numbers of psychologists work in medical settings because of the growing acceptance of a biopsychosocial approach to illness. Do training programs prepare sufficient numbers of graduates to function effectively in medical settings? The authors describe the process of adding an inpatient medical-surgical consultation-liaison (C-L) service to a psychology internship's training rotations, the learning objectives used, and issues in the preparation of trainees for work in medical settings. Psychology trainees added significant capacity to the C-L service. These data may help facilitate the development of C-L training experiences for other programs.
