What do we need in order to successfully treat persons with pathological narcissism? How does change happen? Treatment principles and mechanisms of change emerging from single cases treated by experts: A commentary.

Persons with pathological narcissism (PN) or narcissistic personality disorder present with a wide array of symptoms and social problems. They need effective psychotherapies but empirical evidence for what works with them is mostly lacking. In this issue of the Journal and Clinical Psychology: In Session four authors from different orientations described single cases of patients suffering from different manifestations of PN. In this commentary we reviewed in detail the four cases and tried to distill (a) the treatment principles adopted; (b) the actual mechanisms of therapeutic change. We hope that the list of principles and mechanisms and change we identified here can help both clinicians and researchers develop and test effective options for persons with PN who are difficult to treat but do have chances to change in a meaningful way in treatment.
