Does Servant Leadership Enhance Employee Creativity and Performance? Mediating Role of Knowledge Sharing and Moderating the Role of Self-Efficacy

Grounding on social learning theory, this study investigates the link between servant leadership, employee creativity, and work role performance. To examine the proposed model, the authors collected data from 289 nurses and doctors through a multi-wave (i.e., a time-lag) survey. In this study, servant leadership positively affects employee creativity and work role performance, and knowledge sharing partially mediates the relationship between servant leadership, employee creativity, and work role performance. The results show that self-efficacy directly moderates the positive relationship between servant leadership and knowledge sharing, and indirectly affects the link between servant leadership, employee creativity, and work role performance via knowledge sharing.
