This article is concerned with the utility of the structural equation modeling (SEM) methodology for studying change. Two broad classes of models are considered, individual and group change models. The relationship between the constant rate of change and simplex models, as popular representatives of either class, is examined. Both models are shown to be special cases of the comprehensive latent curve analysis (Meredith & Tisak, 1990). Sensitivity of its models to differences in individual… CONTINUE READING
