Leadership styles can have a noticeable impact on emergency nurses' work commitment, which in turn affects the satisfaction of emergency nurses, patients, and organizational productivity. Leadership styles are crucial in overcoming obstacles in the health care system, including enhancing safety and quality achievement and preserving high-performing emergency nurses. Therefore, from the perspective of emergency nurses, this study examines the effect of leadership styles on emergency nurse commitment levels. The 250 emergency nurses were chosen using a convenience method from the public hospitals in Hail City. The research had a quantitative, descriptive, cross-sectional, and correlational design. The Multifactor Leadership Questionnaire (5X short form) and the Utrecht Work Engagement Scale were used to gather information. From emergency nurses' perspectives, transformational leadership styles (M +/- SD =2.07 +/-.85) and transactional leadership styles (M +/- SD =1.84 +/-.63) earned the highest mean ratings from emergency nurses' perspectives, while laissez-faire leadership styles (M +/- SD =1.50 +/-.89) received the lowest mean score. Furthermore, there was a strong statistically significant positive relationship between transformational and transactional leadership styles and emergency nurses' levels of work commitment (r = 0.584, P = 0.000, and r = 0.507, P = 0.000, respectively), but not between laissez-faire leadership styles and emergency nurses' levels of work commitment (r =-.044, p=0.48). The results revealed a statistically significant positive relationship between transformational and transactional leadership styles and levels of job commitment among emergency nurses. However, there was no statistically significant relationship between the laissez-faire leadership style and emergency nurses' ratings of job commitment.
