Nurse personality has traditionally been studied by means of overt and conscious personality inventory data (1, 2, 3, 4, 5, 6). Roe has emphasized that unconscious needs may play a part in determining occupational interest and choice (7, 8, 9, 10). Using interview material and projective test data, she has pioneered in distinguishing the personality patterns of groups of eminent scientists. Rosenberg and Fuller have made an attempt at a dynamic analysis of the nursing student; this was based upon their experience in conducting a human relations seminar with nursing students, rather than upon psychological test data (11). Cleveland has made the first attempt to use a projective test to study the unconscious motivation of nurses (12). He compared groups of student and staff nurses and dietitians using five selected Thematic Apperception Test (TAT) cards, which were scored for six major themes. The present study is an attempt to assess further some of the personality correlates associated with the choice of nursing as a career, using the complete 20-card TAT and scoring for 150 themes.
