This study was designed to assess the level of concern and awareness of biomedical ethics among nursing students and to identify the factors that might be influencing or correlated with nursing students’ level of awareness of biomedical ethics. Participants were 435 nursing students in one nursing college in South Korea. Data were analyzed using descriptive statistics, an independent t-test, a one way ANOVA, a Scheffé test, a Pearson Correlation, and a Multiple Regression. The most influential factor for awareness of biomedical ethics was concern of bioethics (β=.517, p<.000), followed by teaching methods (β=.129, p=0.02), age (β=.115, p=.004), desire to study ethics (β=.103, p=.011), interesting teaching methods (β=.096, p=.016), effective teaching methods (β=.090, p=.016) and information source (β=.079, p=.026). These factors accounted for 34.9% of the variance in awareness of biomedical ethics (F=158.279, p=.000). Using the results of this study strategies can be developed to increase the awareness of biomedical ethics among nursing students.
