The leadership literature suffers from a lack of theoretical integration (Avolio, 2007, American Psychologist, 62, 25–33). This article addresses that lack of integration by developing an integrative trait‐behavioral model of leadership effectiveness and then examining the relative validity of leader traits (gender, intelligence, personality) and behaviors (transformational‐transactional, initiating structure‐consideration) across 4 leadership effectiveness criteria (leader effectiveness, group performance, follower job satisfaction, satisfaction with leader). Combined, leader traits and behaviors explain a minimum of 31% of the variance in leadership effectiveness criteria. Leader behaviors tend to explain more variance in leadership effectiveness than leader traits, but results indicate that an integrative model where leader behaviors mediate the relationship between leader traits and effectiveness is warranted.
Prior research offers limited insight into the types of work experiences that promote leadership skill development and the ways that the person and context shape the developmental value of these experiences. In this article, the authors develop a series of hypotheses linking leadership skill development to features of the experience (developmental challenge), person (learning orientation), and context (feedback availability). Based on 225 on-the-job experiences across 60 managers, their results demonstrate that the relationship between developmental challenge and leadership skill development exhibits a pattern of diminishing returns. However, access to feedback can offset the diminishing returns associated with high levels of developmental challenge.
This study examines why and when employees might respond to job insecurity by engaging in workplace deviance and developing intentions to leave—2 activities that are costly for organizations. Drawing on social exchange theory and the theory of moral disengagement, we propose that job insecurity increases workplace deviance and intentions to leave by encouraging employees to morally disengage. We further propose that the strength of the positive association between job insecurity, moral disengagement, and these outcomes is contingent upon 2 aspects of the situation—employees’ perceived employment opportunities outside the organization and the quality of the exchange relationship they have developed with their supervisors (leader–member exchange, or LMX). Two time-lagged studies of Chinese workers provide support for the hypothesized 1st-stage moderated mediation model. Specifically, the indirect effect of job insecurity on organizational and interpersonal deviance and intentions to leave via moral disengagement was positive and significant when individuals had more employment opportunities or when LMX was lower but not when they had fewer employment opportunities or when LMX was higher.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
