SL 理論の妥当性の再検証:―コサイン曲線を用いた包括的検証法の提案― Further validity test of the SL Theory::A proposition for omnibus test by using cosine curve
A new way of validity test was proposed to test the prescriptions for effectivesupervision as specified in Situational Leadership Theory (Hersey & Blanchard,1977). The theory has received little empirical support and has been criticizedon theoretical grounds. Moreover, past validity tests of the theory may be biasedin terms of methodological processes. To address the issue, an omnibus testby using the cosign curve was proposed. Applying the test to data from 1195salespeople across 374 stores working for a large Japanese apparel companyshowed no support for the theory. With the help of the test, the authoradditionally explored the modified assumptions of the theory that followermaturity moderates the relationship of leader task and relationship behaviorswith indicants of follower performance.
