List all the group names according to the text specified in the GROUPING variable in Mplus along with their group number.
Enter the number of categories for each indicator in the factor:
Select the syntax you want to use and copy it into the Mplus software program to run your model.
After you have copied the syntax from Step 1 and inserted it into each Mplus input file, run each of the models and save them individually. Be careful not to remove the !MODEL# DO NOT REMOVE THIS COMMENT when pasting the syntax and running each of the models.
After running the models click on File input below and select all five of the Mplus output files and once they appear in the box below click Continue.
When you click Continue, an Excel file should download automatically containing the invariance testing results based on (delta) changes in the CFI, RMSEA and SRMR between models.
The purpose of this tool is to help you generate the syntaxes needed to run measurement invariance analyses for Bifactor Exploratory Structural Equation Modeling (B ESEM) with ease, as the process can become quite tedious and complex with the potential for human error. The tool is based on the technical supplement of Morin (In Press):
Morin, A.J.S. (In Press). Exploratory structural equation modeling: Technical supplements. In R.H. Hoyle (Ed)., Handbook of Structural Equation Modeling, Second Edition. Guilford.
IMPORTANT NOTE: This tool is currently only designed for multi-group tests of measurement invariance. For longitudinal models, you can study Morin (In Press) for the model specification such as bifactor ESEM invariance for longitudinal models (T28-T57).
