I'm researching and trying to find the reference for that--if only to be able to refute it. It's Bowen family systems theory, self-differentiation et al. And everything else I've read and studied about family systems is spot on. For me, it's a really good framework for understanding; it brought me through some difficulty after my last divorce, helped me define where the work is. I rail against having this define me, however.
