Introduction to Path Analysis and Mediation Analysis

Path analysis and mediation are commonly used in the social sciences but have also proven to be useful techniques in other fields. Mediation occurs when an independent variable X affects a dependent variable Y partly or completely through an intermediate variable Z. This workshop will introduce the concept of mediation and describe situations in which it can be used. The difference between mediation, moderation, and confounding will be highlighted. Through examples, the simple mediation models will be expanded to introduce the more general path analysis technique. Different methods available for the estimation and testing of such models will be introduced.
