The Mediating Effects of Organizational Commitment on the Relationship between Transformational Leadership Style and Job Performance

Nurses are considered the most valuable assets in hospitals, and leadership style is one of the determinants that can affect their performance. The purpose of this study is to examine the mediating effects of organizational commitment on the relationship between transformational leadership style and employees' job performance among Saudi female nurses. Four hospitals located in Riyadh and 227 Saudi female nurses were selected for this study. The results indicate that transformational leadership style is positively correlated with job performance and affective organizational commitment. The findings also reveal that affective organizational commitment mediates the relationship between transformational leadership style and job performance. This study recommends that hospital management should provide the groundwork for instilling transformational leadership styles and mangers should pay more attention to their leadership style in order to enhance job performance. This study also suggests further research that would include different measures and a larger sample as well as other areas, which could result in better understanding of the relationship between the variables.
