Abstract
Psychologists play important roles in the clinical practice of psychiatry. However, they are faced with several problems in their activities at the department of psychiatry, of the university hospital. The main problems are as follows ; (1) although psychologists are essential members in clinical practice, their position is not well established, (2) they are required to have medical knowledge, because they are considerd as the medical staff of the university hospital from the patients point of view, (3) when psychologists treat the patients, they need to keep close communication with physicians in charge in order to bear their share of the responsibility.
