I am thinking in applying the Exploratory Structural Equation Modelling (ESEM) technique to evaluate the factor structure of a personality inventory. I have recently read about Set-ESEM, which Marsh et al. (2019) described as follows:
In Set-ESEM, two or more a priori sets of constructs are modeled within a single model such that cross-loadings are permissible within the same set of factors (as in Full-ESEM) but are constrained to be zero for factors in different sets (as in CFA).
I know that the psych package in R can perform ESEM analysis, but I was wondering if it is possible to use this or another package in order to conduct Set-ESEM.
Thanks in advance,
