This workshop will give a practical overview of exploratory (EFA) and confirmatory (CFA) factor analysis. EFA topics to be covered include factor extraction, principal components analysis, estimation methods, factor rotation, refining the factor structure, and generating factor scores for subsequent analyses. The latter portion of the seminar will introduce CFA topics such as identification and model fit, and present examples of a one, two and second order factor structure. SPSS will be used for the EFA portion of the seminar and Mplus will be used for the CFA portion.
