RESUMEN
BACKGROUND: Nurses have a crucial role in identifying spiritual needs and providing spiritual care to patients living with cancer. AIM: This study evaluated Iranian oncology nurses' spiritual care competence and its relationship with job satisfaction and moral distress. METHOD: This cross-sectional study was conducted on 280 Iranian oncology nurses in 2020 using four questionnaires: demographic questionnaires, the Spiritual Care Competence Questionnaire (SCCQ), the Minnesota Job Satisfaction Questionnaire (MSQ) and the nurses' Moral Distress Questionnaire (MDS-R). FINDINGS: The mean scores indicated a medium to high Spiritual Care Competence (SCC), mild to moderate moral distress and high job satisfaction. There was a positive correlation between SCC and external job satisfaction (r=184, p<0.05) and a negative correlation between SCC and moral distress (r=-0.356, p<0.05). CONCLUSIONS: SCC diminishes with decreasing external job satisfaction and increasing moral distress. To improve the SCC of nurses working with patients living with cancer, it is recommended that nursing managers and policymakers revise the organisational policies to tackle the obstacles and consider the related factors to provide an ethical climate, implement quality spiritual care and increase job satisfaction.
