Publication Date: July 17, 2026
Magazine: Journal of Business Research (ResearchGate)
Main Conclusions:
- Meta--Analytic Evidence: A meta--analysis of 63 independent studies (N = 18,500) confirms that servant leadership is a robust predictor of innovative work behavior (r = 0.41), significantly enhancing creative output by fostering a supportive and growth--oriented environment.
- Experimental Results: A field experiment involving 503 employees demonstrated that leaders trained in servant leadership principles—specifically humility, stewardship, and healing—saw a 20% increase in employee--initiated process improvements compared to control groups.
- Mediating Role: The relationship is primarily mediated by "organizational citizenship behavior" (OCB) and a heightened sense of "psychological ownership," which encourages employees to proactively suggest and implement new ideas without fear of failure.
