المستخلص

This study examines how perceived leader narcissism (PLN) influences organizational deviance (OD) among academic staff in Egyptian universities, with ego depletion (ED) as a mediator and generational cohort (GC) and institutional type (IT) as moderators. Drawing on conservation of resources theory and ego depletion theory, we argue that narcissistic leaders deplete employees’ psychological resources, increasing their likelihood of engaging in deviant behavior. Data were collected from 297 academic staff across public and private universities using a survey design and analyzed with partial least squares structural equation modeling (PLS-SEM).

The findings indicate that PLN has a positive and significant effect on OD (supporting H1), and that ED mediates this relationship (supporting H2). Generational cohort produced nuanced effects: younger academics were more reactive to narcissistic leadership in terms of depletion and deviance, whereas older academics were more affected in the depletion–deviance pathway, highlighting age-based differences in vulnerability (partially supporting H3). Institutional type also moderated the direct PLN–OD relationship suggesting contextual variation across public and private universities (supporting H6).

This study contributes to the literature by clarifying the psychological mechanisms linking PLN and OD and by identifying generational and institutional contingencies in higher education. The results highlight the destructive impact of narcissistic leadership on academic environments and underscore the importance of leadership development and resource-based interventions to mitigate workplace deviance.
