A descriptive, cross-sectional study aimed to determine the inclination of nursing students towards ethical values and the effects of these values on care behaviours. The data for this study were collected from 466 students studying from May 13–24, 2019. The data were collected using a questionnaire on the sociodemographic characteristics of the students, Inclination to Ethical Values Scale (IEVS), and Caring Behaviors Inventory-24 (CBI-24). In this study, 43.1 per cent of them belonged to families who had a protective attitude. The (...) total mean (SD) IEVS and CBI-24 scores were 63.99 (12.68) and 117.19 (17.95), respectively. The mean item score was 4.88 (0.74). A moderate positive correlation was observed between the inclination of the students towards ethical values and their care behaviours. The general family structure of the nursing students and their participation in an ethics class affected the inclination of the nursing students to ethical values and their care behaviours. This study showed that the ethical values of the students positively affected their care behaviours. (shrink)
