I have conducted an exploratory factor analysis with maximum likelihood (MLFA) and oblique rotation (Promax). I am now trying to estimate validity and reliability (AVE, CR, etc.) moving beyond Cronbach's alpha, as most suggest. Can this be done in the context of MLFA, using the structure matrix of the model? Or should I conduct a confirmatory factor analysis (CFA) of the model to obtain goodness of fit indices and related AVE, CR, etc.?
