Leader esteem for the least preferred co-worker score, training, and effectiveness: an experimental examination.

A laboratory experiment supported Fiedler's Contingency Model analysis of leadership training. The effect of leadership training on group performance was contingent on leadership style, that is, the leader's relation to his least preferred co-worker (LPC). Training improved the performance of high LPC leaders, but was detrimental to the performance of groups with low LPC leaders. High intelligence leaders profited more from training than low intelligence leaders, but low intelligence leaders were more productive overall. Leader LPC times Intelligence interactions indicated that follower satisfaction and interpersonal affect were highest for groups with high LPC-low intelligence leaders or low LPC-high intelligence leaders. Implications for contingency theories of leadership are discussed.
