I'm partial to Lorna Benjamin's Interpersonal Approach, as detailed in

Interpersonal Diagnosis and Treatment of Personality Disorders: Second Edition (Guilford, 2002). I wouldn't get too hung up about "valid treatments" and be open to the wide range of treatment approaches, and to simply understanding the disorder.

Dear Christina,

I hope these resources would interest you.

Dear Stephen, 

"This case study draws mainly from James Masterson’s developmental, self, and object relations approach to the treatment of closet narcissism." Is closet narcissism the same as covert? i have not met the word in English before.

Dear Beatrice,

Thanks for your message. Yes, the closet/stealth narcissist and the covert narcissist are synonymous to each other. According to some, it is more difficult to recognize covert narcissists than the overt ones. Please see the following links.

Dear Stephen, 

Thank you very much for your answer and resources! "This abuse is so well hidden within the communication dynamics of the relationship that the victim often doesn't pick up on it and is left scratching their head wondering "is it me?"

Have you met any NPD who voluntarily seeks help?

Dear Beatrice,

Not usually, but some of them came in for depression or anxiety or relationship problems. They didn't come in with full-blown personality disorders, but I'd discern some narcissistic traits in them after having worked with them for a while and/or together with their significant others.

Dear Stephen, 

According to my experience their significant other can not express her (80%) freely and understandable in these situations. She usually seems to be the one to blame. At least she is the one containing the NPD:s distress. 

Dear Beatrice,

Yes, the interpersonal dynamics you described could indeed play out in therapy. Sometimes we miss them.

Yet overt or even covert narcissists would somehow show their personality features as we come to know them over time. The treatment of NPD is still very challenging.
