Session Type: Exchange Symposium
The complex phenomena that define human development often require an analytic framework that allows for population heterogeneity with a focus on individual differences. As such, developmental researchers are increasingly employing person-centered analytic approaches for their investigations. Finite mixture modeling (FMM) is one of the more popular analytic frameworks for person-centered analysis. FMMs assume that the overall population is comprised of two or more (latent) subpopulations, mirroring the formulation of some notable developmental theories which posit substantively-distinct developmental differences across individuals in the overall population.
Despite their utility for person-centered analyses, effectively applying FMMs in real data settings presents challenges for developmental researchers. These challenges exist, in part, because FMM methodology is an active area of statistical research and, as such, guidelines and best practices for applications are rapidly evolving with few accessible resources for applied researchers.
The goal of this exchange symposium is to stimulate discussion regarding how developmental researchers and methodologists can productively collaborate in identifying, translating, and implementing statistical best practices as they relate to the use of mixture modeling in developmental research. The symposium includes four short presentations highlighting some of the contemporary challenges in applied developmental research with mixture models: Appropriate handling of missing data; identifying the number and nature of the latent subpopulations; evaluating longitudinal invariance of the subpopulations; and identifying antecedents and consequences of subpopulation membership. Each paper includes a substantive example with implications for clinicians, educators, and parents to emphasize the transdisciplinary opportunities inherent in addressing these methodological challenges for applied mixture modeling.
