Moderation and Mediation in Structural Equation Modeling: Applications for Early Intervention Research

Abstract

Second-generation early intervention research typically involves the specification of multivariate relations between interventions, outcomes, and other variables. Moderation and mediation involve variables or sets of variables that influence relations between interventions and outcomes. Following the framework of Baron and Kenny's (1986) seminal paper, this paper differentiates moderation and mediation conceptually and methodologically. Four cases of moderation defined by the scale of predictor and moderator variable scales are descri Show more
