Background: Cultural intelligence enables head nurses to navigate cultural differences, which not
only improves team cohesion and staff well-being but also enriches the delivery of patient care and
subsidizes the sustainable management of healthcare resources. Aim: To assess cultural intelligence and
its relation to sustainable management behaviors among head nurses. Design: A descriptive correlational
design was utilized to conduct this study. Setting: The study was conducted in all inpatient units of the
medical and surgical departments at Benha University Hospital. Subjects: All available head nurses and
their assistants (61) working at the previous setting. Tools: Two tools were used for data collection (I):
Cultural Intelligence Scale and (II): Sustainable Management Behaviors Scale. Results: More than half
(52.4%) of the studied head nurses had a moderate level of cultural intelligence, and slightly more than
three-quarters (75.4%) had sustainable management behaviors. Conclusion: There was a highly
statistically significant positive correlation between total cultural intelligence and total sustainable
management behaviors among head nurses. Recommendations: Conducting continuous training
programs to improve head nurses' awareness about cultural intelligence for achieving organizational
sustainable management behaviors. Additional research is needed to understand the challenges associated
with implementing sustainable management in the health-care system.
