Changes have occurred in the training of interns and the functioning of psychologists at Ohio State University Medical School, some of which was effected by their psychometric laboratory. The number of tests administered by interns has decreased markedly. The existence of the laboratory changed training experiences and opportunities. Psychologists were free to spend more time talking with the patient and to order appropriate tests, thus their roles as consultants and problem solvers was emphasized. The psychologist was also in a better position to get his information into the system early while decisions were still being made. One side effect caused by the existence of the lab is that interns frequently do not consider it worthwhile to master projective testing techniques, but see the testing role as one appropriate for technicians, not professionals. Training requirements have shifted, from demanding an intern to demonstrate ability in the use of tests to today's requirement that they be able to evaluate clinical problems and formulate appropriate intervention. This training model has met the needs of the interns and staff and the demands of the setting. (Author/SM)
