Moderator variables (moderators) are of considerable interest to researchers in various academic disciplines (e.g. human resources management, industrial and organizational psychology, management, organizational behavior, and organizational theory) who study phenomena involving the interactive effects of two or more independent variables. Several comprehensive reviews of the literature on moderators have appeared in the past three decades (e.g. Stone, 1988; Zedeck, 1971). Since the latest of these reviews, a large number of papers have been published on moderator-related issues. Unfortunately, however, there is no relatively comprehensive, up-to-date review of this literature. Thus, the purpose of this article is to provide such a review. Among the topics considered in it are conceptual definitions of moderators, prior reviews of the literature on moderators, major strategies for detecting moderators, and strategies for increasing statistical power in studies of moderators.
