Unveiling the Mechanisms through Which Leader Integrity Shapes Ethical Leadership Behavior: Theory of Planned Behavior Perspective.

Leadership integrity is crucial in shaping ethical leadership or promoting a rigorous adherence to moral principles and standards. This study explores the intricate relationship between leader integrity, moral identification, self-regulation, and ethical leadership behavior, providing practical insights for healthcare leaders seeking to enhance ethical practices. It addresses a critical gap in the research landscape by focusing on individual-level ethical leadership within the healthcare sector, where prior investigations have been limited. This study examines the mediating role of moral identification among leader integrity and ethical leadership behavior. We surveyed 181 health sector workers and employed SmartPLS to assess the conceptualized relationships. The analyses reveal a significant indirect influence of leader integrity on ethical leadership behavior, whereas moral identification mediates the relationship. Our findings further indicate an intriguing moderation effect of self-regulation on the relationship between moral identification and ethical leadership behavior. This divergence from previous research underscores the significance of contextual and methodological factors in studying leadership integrity and ethical behavior. Our study contributes to the literature on the relationship through planned behavior theory by demonstrating that moral identification mediates the relationship between leader integrity and ethical leadership behavior in the context of the theory of planned behavior. Our findings underscore the significance of fostering leader integrity within organizations to indirectly promote ethical leadership behaviors through moral identification. Organizations should prioritize initiatives that cultivate moral identification among their members to enhance ethical cultures.
