In recent years, South Korea has become more concerned about a dignified death and the 'well-dying' law has been enacted. Oncology nurses' perceptions of death are crucial in maintaining dying patients' sense of dignity; fostering their physical, mental, and spiritual quality of life; and ensuring that they die a comfortable death. This study accordingly examined the relationships between attitudes towards a dignified death, compassion competence, resilience, and occupational stress to provide basic data to promote better attitudes towards death among oncology nurses in South Korea. This study, conducted between 2 to 31 January 2018, adopted a descriptive cross-sectional design. Oncology nurses (N = 329) participated, and the differences in their attitudes towards a dignified death correlating to their demographic and work-related characteristics were analysed using t-tests and analyses of variance. Pearson's correlations were used to examine the relationships between nurses' attitudes towards a dignified death, compassion competence, resilience, and occupational stress. Participants' attitudes towards a dignified death were weaker than those of the general population but stronger than those of non-oncology nurses. Attitudes towards a dignified death were significantly correlated with compassion competence and resilience-traits that appear to enable nurses' efficient response to various stressful situations. Educational programmes should promote nurses' compassion competence and resilience. Nurses should receive death-related education to reduce the stress that arises from providing end-of-life care and enhance their attitudes towards a dignified death.
