The Validity of Hersey and Blanchard's Theory of Leader Effectiveness

In: Group & organization studies, Band 7, Heft 2, S. 225-242

Abstract

This study examined the use and validity of Hersey and Blanchard's Situa tional Leadership Theory. Several predictions were made from theory: that high performing managers will be rated higher than low performers on leader effectiveness and flexibility of style, both in self-report and by subordinates and superiors, and will show greater knowledge and use of Situational Leadership; and that managers will generally rate subordinates' job performance more highly when applying the theory correctly. Subjects were 65 managers, 189 subordinates, and 56 supervisors. The results support the validity of the theory, suggesting that when it was applied correctly, the gain in subordinate job performance was both practically and statistically significant. No definite causal relationship could be established, however, because of research design constraints.
