Ag. Bedeian et Kw. Mossholder, SIMPLE QUESTION, NOT SO SIMPLE ANSWER - INTERPRETING INTERACTION TERMS IN MODERATED MULTIPLE-REGRESSION, Journal of management, 20(1), 1994, pp. 159-165

ng moderated multiple regression (MMR) analysis is considered. It is a
rgued that given a theory-based, a priori hypothesis, an MMR analysis
is analogous to a planned statistical comparison and, thus, a signific
ant overall F value is not a prerequisite for interpreting a significa
nt interaction term.
