AbstractEffective leaders employ a blend of transformational and transactional leadership styles to collaborate with their employees, working towards achieving organizational objectives. While the significance of enthusiasm in leadership is acknowledged, its specific role remains largely unexplored within the realm of leadership studies. We contend that enthusiasm assumes a pivotal and influential role in successful leadership, ultimately enhancing overall productivity. This study is dedicated to investigating how leader enthusiasm impacts perceived performance among team members and examine the mediation of group satisfaction and positive emotions in the relationship between leader enthusiasm and perceived performance. By analyzing data collected from a participant pool of 311 individuals, our research yields compelling evidence that leader enthusiasm exerts a positive influence on perceived performance. A noteworthy revelation emerging from our research is found in the mediation analysis. This analysis sheds light on the pivotal roles of group satisfaction and positive emotions as key mediators in the link between leader enthusiasm and perceived performance. This underscores the concept that leader enthusiasm indirectly shapes how employees perceive their own performance, primarily through its profound impact on group satisfaction and the positive emotions experienced by individual team members. In summary, our study underscores the vital and transformative role of leader enthusiasm in cultivating a rewarding and fulfilling work environment. This, in turn, exerts a positive influence on follower emotions and their perceptions of performance. Our findings shed light on the intricate mechanisms through which leader enthusiasm contributes to shaping employees’ perceptions of their performance.
