# Latent variable interactions/moderation

[![Latent interaction regression model][1]][1]

I am trying to figure out how to include interaction effects in SEM. Can I simply multiply the latent indicator variables? [Marsh et al. (2012)][2] decribes this as a problematic, and rather recommends a standardized solution first described by Wen, Marsh and Hau (2010). I am unsure how to implement such a model in OpenMx, however.

I'd be grateful for any input on what the best solution for including latent interactions would be, and how to implement them in an OpenMx model.
