Idiographic Item Response Theory: Modeling Person-Specific Differential Item Functioning in Intensive Longitudinal Data.

Idiographic theories of psychological measurement emphasize that the relationships between item responses and a latent trait may vary across individuals, yet typical item response theory (IRT) models assume item parameters are constant across persons. We propose an IRT approach for modeling person-specific (idiographic...

Bayesian Hierarchical Moderated Factor Analysis for Testing Measurement Invariance in Multilevel Data: Model Development, Simulation Studies, and Experience Sampling Application

Abstract Moderated Nonlinear Latent Factor Analysis (MNLFA) has been introduced as a flexible approach for testing measurement invariance among categorical and continuous covariates. Equipped with Bayesian shrinkage priors, MNLFA can handle large numbers of covariates and potentially invariant item parameters. The pres...
