This study explored the frequency of providing aspects of spiritual care intervention and its association with nurses' own spiritual well-being in a convenience sample of 355 Jordanian Arab Muslim nurses. The nurses were recruited from different hospitals, representing both public and private health care sectors in northern and central Jordan. A cross-sectional descriptive and correlational design was used. Results indicated that Jordanian Muslim nurses provided religious aspects of spiritual care intervention to their Muslim patients infrequently and that their own spiritual well-being was positively associated with the frequency of provision of spiritual care interventions. The study concluded that Jordanian Muslim nurses most frequently provided spiritual care interventions that were existential, not overtly religious, were commonly used, were more traditional, and did not require direct nurse involvement. Moreover, the findings revealed that spiritual well-being was important to those nurses, which has implications for improving the provision of spiritual care intervention. The study provides information that enables nurses, nursing managers, and nursing educators to evaluate the nurses' provision of various aspects of spiritual care to their Muslim patients, and to identify aspects of spiritual care intervention where nurses might receive training to become competent in providing this care.
