Background: Spiritual care is a growing field of interest in the healthcare industry in Saudi Arabia, one that is largely defined by the religious and cultural context of the country that has a rich and strong backdrop. Workplace spiritual climate may have a significant impact on nurses’ ability and willingness to provide spiritual care. This study aims to examine the influence of workplace spiritual climate on nurses’ provision of spiritual care. Methods: A convenience sample of 918 nurses employed in seven public hospitals in Saudi Arabia was surveyed in this cross-sectional study using the Spiritual Climate Scale (SCS) and the Spiritual Care Intervention-Provision Scale (SCIPS). Results: The overall mean in the SCS was 64.58 (SD = 24.60), whereas the overall mean in the SCIPS was 56.83 (SD = 9.46). Nurses with Saudi nationality, with Islamic faith, with administrative functions, and with higher years of experience as a nurse reported better perceptions of workplace spirituality. Hospital, position, years of experience in the present hospital, and the hospital’s spiritual climate were identified as significant predictors of the nurses’ spiritual care interventions provision. Conclusions: The results of the study support the importance of having good workplace spiritual climate as it impacts the nurses’ provision of spiritual care interventions.
