Medical personnel is reported to have a protective attitude, but the problems of nurses’ dialog attitudes include confusion, concern, prejudice, and difficulty in dialog with patients with critical illnesses. Therefore, we had developed the scale to evaluate the negative aspects of nurses’ interactive attitudes toward the elderly. The validity and reliability for the scale of the 15-item and 7-law methods were determined. A comparison of the dialog orientation scales of nurses and nursing students revealed that nurses are more positive as they gain more experience. Additionally, nurses were more negative about age discrimination in dialog and the difficulty of dialog with seriously injured people than caregivers because nurses care for more severely ill elderly. Moreover, we implemented a program to conduct dialog training with the elderly from the stage of nursing students, which revealed a clear effect.
