On November 1, 2016, Dr. Joseph Hammer and Dr. Michael Toland presented this 50-minute talk at the University of Kentucky on Bifactor Analysis in Mplus, the second presentation in the Fall 2016 Applied Quantitative and Psychometric Series (AQPS). This presentation introduced the bifactor confirmatory factor analysis (CFA) model: what it is, when to use it, how to run it in Mplus, and how to use follow-up Explained Common Variance and Omega coefficients to answer questions about the internal structure and reliability of multidimensional scales/instruments used in research.
