Question: For patients with narcissistic personality disorder, which type of psychotherapy achieves the best outcomes in terms of mood and quality of interpersonal relationships?

Answer:

As no evidence was identified, no clinical implications could be made. The authors of a systematic review suggested that future research should evaluate treatments for NPD using clinical trials. They also suggested that it may be worth investigating different approaches to the diagnosis of NPD, and to evaluate the implications of these approaches for efficacious treatment. They also noted, however, that the low prevalence of this disorder may make such studies difficult.
