A recent methodological focus in the SEM literature concerns the modeling of interactions, and the extension and application of SEMs to situations with nonlinear relationships involving latent variables (Jaccard & Wan, 1996; Schumacker & Marcoulides, 1998). Several approaches have been proposed (see Schumacker & Marcoulides, 1998), each of which relies on the pioneering work of Kenny and Judd (1984). Li, Harmer, et al. (1998) provide a full explication and comparison of three such approaches to modeling interactions with static latent variables.
