Yes i've heard of it and read about it - as far as i'm aware schema is more widely available in the general sense though i'm not as aware of it's success rates.

For me, the best kind of therapy for BPD would be mentalization based therapy - it was developed in my country but annoyingly enough isn't widely available. It's not overly conceptualized and deals more with present interaction/communication. I'd recommend anyone give it a go...there are actually loads of therapies for BPD. I had a long list on my computer which seems to have vanished but if i find it i'll post it.
