TITLE:  A Formal Test of Moderated Mediation

ABSTRACT:  Methods for testing a hypothesis about "moderated mediation" that have become widely used in the behavioral science  literature are piecemeal approaches that do not formally test whether the indirect effect in a mediation model is moderated. In this talk I  introduce a formal test of moderated mediation based on a hypothesis test or interval estimate of the parameters of a function liking the indirect effect to values of a moderator. Real-data examples are provided for different forms of moderated mediation, and the implementation of the method is illustrated using software such as the PROCESS procedure for SPSS and SAS as well as Mplus.
