<p>This study advances the literature on star performers by proposing and empirically testing a regulatory focus theory-based model that explains how star-turned-empowering leadership (STEL) influences employee creativity through two key cognitive pathways: rumination (an indicative of a prevention focus) and role breadth self-efficacy (an indicative of a promotion focus). Additionally, the study incorporates contextual influences by examining the moderating role of psychological safety in shaping employee responses to STEL, particularly in terms of promotion and prevention focus. Findings from two time-lagged, multi-source field studies provide support for the proposed relationships. Study 1 shows that STEL is positively related to rumination, role breadth self-efficacy, and employee creativity, with both mediators significantly linking STEL to creative outcomes. Study 2 replicates and extends these findings by demonstrating that psychological safety strengthens the positive association between STEL and role breadth self-efficacy while weakening the positive relationship between STEL and rumination. In particular, employees who perceive a high level of psychological safety are more likely to respond positively to STEL by concentrating on opportunities and potential gains, thereby fostering enhanced creativity. Implications for theory and practice are discussed in the later section.</p>
