| Abstract | As is the case for any statistical model, a multidimensional latent growth model comes with certain requirements with respect to the data collection design. In order to measure growth, repeated measurements of the same set of individuals are required. Furthermore, the data collection design should be specified such that no individual is given the same item twice, while at the same time allowing for common items over time so that different measurement occasions can be linked. An example of such a data collection design is presented. A computational challenge arises due to the high dimensional nature of a multidimensional latent growth model. Not only are there multiple dimensions within each measurement occasion, but insofar not all individuals change at the same rate for a given construct, that construct will also give rise to multiple dimensions over time. Fortunately, the computational burden can be overcome insofar as one is willing to incorporate assumptions on the latent structure, such as a bifactor or higher order structure within measurement occasions, and the assumption that the construct at a particular time point is independent of the construct at all previous time points given the construct at the immediately preceding time point (first order Markov assumption).
