Moral courage means the practice of ethical values in the face of moral problems, is required by ethical professionals such as nursing and its prerequisite is to train and enhance this feature in the student's period. The purpose of this study was to determine the moral courage of nursing students in Iran. This descriptive cross-sectional study was carried out in 2017 on 185 samples from Shahid Beheshti University of Medical Sciences in Tehran. The data were collected using the moral courage questionnaire (Sekerka et al., 2009) and analyzed using descriptive and analytical statistics in SPSS version 24 software. Mean score of moral courage for nursing students was 52.75 ? 9.11 (range 15-75). The highest and lowest mean dimensions were related to moral factor (11.09 ? 2.66) and threat tolerance (9.56 ? 1.71), respectively. The educational level (p = 0.04) and the choice of nursing with interest (p = 0.04) had a positive and significant relationship with moral courage. In this study, the moral status of nursing students was favorable. Given this finding, this moral attribute can be reinforced in them, so that they can have moral reasoning in the clinical environment and make the right decisions in the face of moral problems. © 2018 Transilvanian Association for the Literarure and Culture of Romanian People (ASTRA).
