Chou, Chih-Ping; Bentler, Peter M.; Pentz, Mary Ann – Structural Equation Modeling, 1998
Compares two statistical approaches to modeling growth across time: the multilevel model and latent curve analysis. A longitudinal data set from a school-based substance-use-prevention model for adolescents (2,779 students) illustrates differences and similarities between the approaches and shows very compatible results for both.

Moustaki, Irini; Joreskog, Karl G.; Mavridis, Dimitris – Structural Equation Modeling, 2004
We consider a general type of model for analyzing ordinal variables with covariate effects and 2 approaches for analyzing data for such models, the item response theory (IRT) approach and the PRELIS-LISREL (PLA) approach. We compare these 2 approaches on the basis of 2 examples, 1 involving only covariate effects directly on the ordinal variables…
