Shame in patients with narcissistic personality disorder.

Shame has been described as a central emotion in narcissistic personality disorder (NPD). However, there is a dearth of empirical data on shame in NPD. Patients with NPD (N=28), non-clinical controls (N=34) and individuals with borderline personality disorder (BPD, N=31) completed self-report measures of state shame, shame-proneness, and guilt-proneness. Furthermore, the Implicit Association Test (IAT) was included as a measure of implicit shame, assessing implicit shame-self associations relative to anxiety-self associations. Participants with NPD reported higher levels of explicit shame than non-clinical controls, but lower levels than patients with BPD. Levels of guilt-proneness did not differ among the three study groups. The implicit shame-self associations (relative to anxiety-self associations) were significantly stronger among patients with NPD compared to nonclinical controls and BPD patients. Our findings indicate that shame is a prominent feature of NPD. Implications for diagnosis and treatment are discussed.
