This study aims to investigate how transformational leadership and empowering leadership influence employee creativity, with a focus on the roles of creative process involvement, intrinsic motivation, and psychological empowerment as mediators. Data were collected from 420 employees working in 21 telecommunication companies in Vietnam through a direct survey using questionnaires. Structural equation modeling (SEM) and confirmatory factor analysis (CFA) were used to analyze the data. The results show that both empowering and transformational leadership styles influence employee creativity indirectly through mediating factors. Specifically, these leadership styles positively correlate with psychological empowerment, which in turn affects intrinsic motivation and involvement in the creative process. Both intrinsic motivation and engagement in the creative process have a significant positive effect on creativity. The findings suggest that leaders in Vietnam's telecommunications sector should carefully consider their leadership approach, as fostering employee creativity is strongly associated with enhancing intrinsic motivation, psychological empowerment, and creative process engagement.
