I did a terrible job at offering caveats to what I was saying. I should have prefaced my post conceding that the failure of a particular therapy isn't necessarily the fault of the client. I freely acknowledge that there are good and bad fits/poor chemistry, and not all modalities are appropriate.

My only contention is with speaking in absolutes (i.e. "all therapy is bad because I had bad therapy"), and overlooking the responsibility of the client side in the therapy. Not saying that's all applicable here, but these are considerations.

That all said, there are apparently several emerging therapies which have had significant success in NPD, so treatment modality and therapist ability are obviously important. Schema therapy is now being hailed as one of the most effective, but a few variations of psychotherapy have also helped lead the charge in this disorder most recently. Even things like specialized subclassifications of Cognitive Behavioral Therapy, Mindfulness, and especially a form of Mindfulness called Loving-Kindness meditation are pushing around our old ideas about how stubborn this disorder is supposed to be.

So therapy can be effective, but that situation needs both someone who knows how to work with the disarming the NPD mechanisms and a completely receptive and open client.
