psychometrics is a much larger concept than needing change in the brain for an interventional investigation of causation. Also, "correlational" is a very old concept. I went through the papers that you listed here, and you are right about exploratory factor analysis being as good as reading tea leaves. I mean, its as bad as p-values and the confidence intervals. But there is much more modern work. You should check out COSMIN consensus work.
