It is very significant therefore that Kenny hasdecided to introduce causal mediation analysisto the community of SEM researchers which, until very recently, felt alienated from recentadvances in causal mediation analysis, primarily due tothe counterfactual vocabulary in which it was developedand introduced. With Kenny kind permission, I am posting his description below, because it is one of the few attemptsto explain causal inference in the languageof traditional SEM mediation analysis and, thus, it may serve to bridge thebarriers between the two communities.Next you can find Kenny new posting, annotated with my comments. In these comments,I have attempted to further clarify the bridges betweenthe two cultures; the and the will refer to the former as (for Baron and Kenny)and to the latter as (for lack of a betterword) although, conceptually, both BK and SEM are fundamentally causal.From Melanie Wall, University of Minnesota:I am teaching a course in latent variable modeling (to biostatistics and other public health students) and was yesterday introducing path analysis concepts including direct and indirect effects.I showed them how to calculate indirect effects by taking the product of direct paths.
