The purpose of this quantitative quasi-experimental vignette study was to examine the effects of principals' empowering (versus non-empowering) leadership styles and gender on teachers' creativity. Measurement was based on teachers' perceptions of how they would behave creatively if working for a principal described in a randomly assigned vignette as measured on the Zhou and George's (2001) scale. The study addressed the void in the research literature identified by Özaralli (2015) by investigating the relationship between empowering leadership and creativity in the sector of education. Participants included 128 randomly selected teachers from a public-school district in Louisiana. A Two-way ANCOVA was initially planned, but a significant interaction effect was identified between a covariate and one of the independent variables while investigating the homogeneity of slopes assumption. Therefore, a Two-way ANOVA was preferred to investigate the relationships between principals' empowering leadership style, gender, and creativity. The interaction effect between principals' empowering leadership and gender on teacher creativity was also examined. Results of the ANOVA identified a significant relationship (p = 0.006) between principals' empowering leadership and teacher creativity, a non-significant relationship (p = 0.380) between principals' gender and teacher creativity, and there was no two-way interaction effect (p = 0.886) identified between empowering leadership and principals' gender on teacher creativity. Results suggest that principals who exhibit empowering (versus non-empowering) leadership behaviors are likely to have a positive effect on the creativity of the teachers who work under their leadership. These findings contribute to the literature and suggest areas of future study. [The dissertation citations contained here are published with the permission of ProQuest LLC.
