When performing principal components analysis (to reduce the amount of information and transform variables into continuous variables) before applying PLS-SEM (formative model), is it necessary to check the convergent validity of the constructs?

Hello Ana Castanho In my opinion, the use of PCA in binary data will not be very interesting. You can understand this from PCA assumptions.
Using Cluster Variables analysis, which you can easily do with Minitab, will provide a better answer in this data.
