The present study tested the validity of the Vroom/Jago`s model, a revised version of the Vroom/Yetton`s(1973) normative leadership theory, using 140 Korean middle-level managers. The subjects were asked to select a document that they have not dealt with, but will do in the near future, and to choose a decision-making method out of AI through GII that they would use in solving the problem in the document. Also, they were asked to analyze the documented problem in terms of 12 attributes provided by the model. About 2 weeks later, when documented problems had been dealt with, their results were evaluated by the middle-level managers on decision quality, decision commitment, subordinate development, cost, time penalty, and decision effectiveness. The results of each problem were also evaluated by each middle-level manager`s superior and subordinate on decision effectiveness. The results of the measurements were then correlated with those normatively provided by the model. The correlation results showed that the Vroom/Jago model is valid. Some limitations of the study were also discussed.
