Measurement Models: Topics

The table below outlines the topics covered in the three-day measurement models workshop. Measurement models encompass factor analysis models, item response theory models, and some latent class and latent profile mixture models. Measurement models are important for scale development, intermediate outcomes, errors-in-variables models, etc. Briefly, day 1 introduces the kinds of research questions approached using measurement models; an introduction to Mplus software; using Mplus software; and the importance of workflow; finally, measurement models are introduced. Day 2 introduces Item Response Theory (measurement models for ordinal dependent variables) and Differential Item Functioning (DIF) detection. Day 3 expands the discussion of DIF and introduces special modeling issues and approaches, including models with latent classes, complex sampling weights, and Bayesian data analysis.
