Abstract
The implicit attitude toward violations is regarded as a contibuting factor in those violations. Adachi & Usui (2010) applied the Implicit Association Test (IAT) to measure this attitude in nursin. This study examines the IAT's validity and reliability. We conducted the IAT for 51 medical staffs who serve as risk managers in a hospital. The IAT's validity was demonstrated from the difference of the reaction time between the blocks of IAT and by showing that the IAT scores of nurses who had served on a safety-related committee were higher than those of nurses who had not serves on such a committee. A high IAT score indicates that the participant has stronger implicit attitudes (e.g., persons with high scores felt that violations were more distasteful). Reliability was indicated by dispersion between trials.
