Can Patients With Narcissistic Personality Disorder Change? A Case Series

Area of Science:

• Psychiatry
• Clinical Psychology

Background:

• Narcissistic personality disorder (NPD) is a complex mental health condition.
• Limited research exists on the long-term effectiveness of psychotherapy for NPD.

Purpose of the Study:

• To investigate the potential for psychotherapy to facilitate improvements in patients diagnosed with NPD.
• To assess changes in diagnostic criteria and psychosocial functioning following psychotherapeutic interventions.

Main Methods:

• Retrospective analysis of eight patients diagnosed with NPD who showed improvement during treatment.
• Utilized clinician/investigator diagnostic scores from the Diagnostic Interview for Narcissism (DIN) and DSM-5 criteria.
• Evaluated psychosocial functioning in work, school, and romantic relationships before and after therapy.

Main Results:

• All eight patients demonstrated significant improvement after 2.5 to 5 years of psychotherapy.
• Patients no longer met diagnostic criteria for NPD according to both DIN and DSM-5.
• Substantial improvements were observed in psychosocial functioning with large effect sizes.

Conclusions:

• Psychotherapy can lead to meaningful changes and remission in narcissistic personality disorder over a 2.5 to 5-year treatment period.
• Further research is needed to identify specific patient characteristics, therapeutic interventions, and common processes associated with successful treatment outcomes in NPD.
