Narcissistic leadership can benefit organizational performance. Aberrant narcissism can destroy the psychosocial health of groups, limiting performance. This article examines Dependent Organizational Disorder, a common form of narcissism, which infects leadership, thwarts performance, and interrupts organizational learning. Dependent Organizational Disorder is juxtaposed with interruptions in organizational learning and a model illustrating the possible relationship between them is presented. Implications for human resource development are drawn. (Contains 3 tables.)
