Hypotheses involving mediation are common in the behavioral sciences. Mediation exists when a predictor
affects a dependent variable indirectly through at least one intervening variable, or mediator. Methods to assess
mediation involving multiple simultaneous mediators have received little attention in the methodological literature
despite a clear need. We provide an overview of simple and multiple mediation and explore three approaches
that can be used to investigate indirect processes, as well as methods for contrasting two or more mediators
within a single model. We present an illustrative example, assessing and contrasting potential mediators of the
relationship between the helpfulness of socialization agents and job satisfaction. We also provide SAS and SPSS
macros, as well as Mplus and LISREL syntax, to facilitate the use of these methods in applications.
