With complex models becoming increasingly popular in the social sciences, many researchers have begun using latent variable modeling in multiple-steps, saving, estimating, or otherwise extracting factor scores from one confirmatory factor analysis (CFA) for use in a second inferential analysis. With two or more factors identified in a CFA, there exist few practical guidelines as to how researchers should proceed. In Study 1, we examine two common practices when CFAs have two or more factors: Fitting separate CFAs or allowing them to correlate in the model used for extraction. We provide a simulation study to demonstrate the bias introduced in each of the two approaches. In Study 2, we demonstrate that the between-factor correlation bias can be mitigated through the use of a different estimator; using ten Berge estimation shows near zero bias on the critical correlations between factors. Finally, we demonstrate this with an example dataset.
