Vergleich unterschiedlicher Führungsstile: Das Projekt Context and Leadership Styles (CoLeS)

A major problem in research and theory on effective leadership has been the lack of agreement about which leadership styles are relevant for organizations. Despite more than half a century of research on leadership styles, no integrating leadership theory exists. It is very difficult to compare and integrate the results from past empirical studies that use different sets of behavioral descriptions. Thus, the first goal of project CoLeS is to compare and contrast the currently dominant leadership styles (i.e., transactional, transformational, and ethical leadership, laissez-faire, initiating structure and consideration, and leader-member-exchange). Can these leadership styles be distinguished empirically (i.e., factor analyses)? What is the rivalling effect of these leadership styles on outcome criteria (i.e., affective commitment, job satisfaction). In order to control for the effect of liking (i.e., positive affect), this construct is controlled for in all the analyses. The result of this part of the project will be a condensed set of effective leadership styles, based on empirical data.


The second goal of project CoLeS is to systematically assess the influence of contextual influences on leadership effectiveness. Examples for context factors are leader’s gender, size of organization, follower’s distance to leader, and team heterogeneity. Which of these contextual factors moderate the relationship between leadership styles and outcome criteria? While theoretical work emphasized the importance of context factors within leadership research (e.g., situational constraints in leadership effectiveness), empirical research has been rare. Overall, it is hoped that the condensed set of leadership factors and the systematic assessment of contextual factors will result in advances for leadership theory.
