Where Have all the Moderators Gone: The Perils of Type II Error.

Abstract

Traditional moderated regression analysis requires a significant and sizable increment in R2 due to the interaction term in order to conclude that there is a moderator effect. A Monte Carlo analysis demonstrates that the traditional procedure will not discover moderators even when they are the only existing effect. A suggestion is made to reverse the usual hierarchical order of the moderated regression analysis. The choice between a linear and an interactive model should be made on the basis of theoretical justification. (Author)
