What makes leadership, leadership? Using self-expansion theory to integrate traditional and contemporary approaches

摘要

Numerous traditional theories and paradigms of leadership purport to describe what leadership is. It is difficult to reconcile these traditional approaches, however, if each one alone, independent of the others, is viewed as capturing the actual identity of leadership. In this article, we take an integrative view of traditional approaches to leadership. To do so, we first identify some underlying ideas common to them. Next, we explain how these underlying ideas lead us to a fundamental theory about close relationships-that is, self-expansion theory, which refers to a psychological process in which an individual incorporates another into the self (Aron & Aron, 1986). We then review the traditional leadership theories to explore whether these theories may be linked through self-expansion theory and whether self-expansion may help to explain why boundary conditions have been discovered for all of them. In this process, we explore whether traditional approaches to leadership might also be linked with more contemporary approaches through self-expansion theory. Finally, we discuss the implications for future research and professional practice of the integration of traditional approaches to leadership.
