I would not call it bogus. I don't think any one theory in psychotherapy is any more bogus than any other and if it works for someone, then that is all that matters in my opinion.
I think of it along the lines of this quote from Bull Durham (the only baseball movie I have ever made it all the way through):
"If you believe you're playing well because you're getting laid, or because you're not getting laid, or because you wear women's underwear, then you *are*!"

For me, the woman used to talk about attachment and how mine was all dismissive/avoidant etc. But I don't have a problem with my attachment style. I am fine with it and have no urge to change it. So we had to get that straightened out and the woman finally got off that annoying kick.
