The first thing I'd like to see is some honest effort to measure outcomes with such clients. Without that, the whole thing looks very sketchy. I'd also like to know how it is that a therapist who studies attachment theory is in a position to heal someone's attachment trauma. Doesn't make any sense. What does quality someone to do that? It's impossible to define, therefore it's a dangerous social experiment. As I see it, most therapists are playing a game called "let's dig around and see what pops up".
