Shared and Vertical Leadership: Relationship among Team Satisfaction, Team Commitment, and Team Performance in Hospital Nurses

Purpose: The purpose of this study was to investigate the effects of shared leadership and vertical leadership on team satisfaction, team commitment, and team performance of nurses. Methods: This study was a descriptive survey study. The participants in this study were 165 nurses working at a general hospital located in Gyeonggi-do, Data were collected from March 9 to April 12, 2018 using a structured questionnaire and analyzed with the SPSS/WIN program. Results: Shared leadership and vertical leadership were found to have a positive correlation with the nurse's team satisfaction, team commitment, and team performance. Empowering leadership behavior, one of the sub-factors of shared leadership, had a positive effect on team satisfaction ( β =.25, p =.003), team commitment ( β =.32, p < .001), and team performance ( β =.25, p =.004). Empowering leadership behavior, one of the sub-factors of vertical leadership, had a positive effect on team performance ( β =.32, p =.023). Conclusion: These results show that the team effect of shared leadership is better than that of vertical leadership. It can be concluded that empowering leadership behavior is important in improving the team performance of nurses. Therefore, hospitals and nursing managers should strive to develop the enhanced empowering leadership behavior programs for nurses.
