Open publisher page 46 citations

Abstract

This paper reports a differential diagnostic study of narcissistic personality disorder (NPD) and borderline personality disorder (BPD). The semistructured Diagnostic Interview for Narcissism (DIN) was used on 24 patients clinically diagnosed with NPD and 20 with BPD to assess 33 characteristics imputed to pathological narcissism. The results show that it is possible to discriminate NPD from BPD, and that the most useful discriminators are the criteria describing grandiosity in narcissistic patients.
