The study's objective was to empirically assess cognitive and emotional empathy in patients with narcissistic personality disorder (NPD). To date, "lack of empathy" is a core feature of NPD solely based on clinical observation. The study's method was that forty-seven patients with NPD, 53 healthy controls, and 27 clinical controls with borderline(More)
Emotional abilities were measured with a performance test of emotional intelligence (The Mayer-Salovey-Caruso Emotional Intelligence Test; Mayer, Salovey, & Caruso, 2002) in patients diagnosed with major depressive disorder, substance abuse disorder, or borderline personality disorder (BPD), and a nonclinical control group. Findings showed that all clinical(More)

We hypothesized that implicit-explicit self-esteem discrepancies foster autoaggressive behavior and dysphoria, and impair self-perception. We found that the two(More)
The aim of the study was to investigate gender differences and similarities in patients with borderline personality disorder (BPD) with respect to Axis I comorbidity, Axis II comorbidity, general psychopathology (Symptom Checklist 90-Revised), and dimensional personality traits (NEO-Personality-Inventory Revised [NEO-PI-R] and the Dimensional Assessment of(More)

These impairments are hypothesized to be reflected in low self-esteem and low self-concept clarity. The objective of this study was to evaluate the impact of an inpatient dialectic(More)

However, the effect of individual differences in cognitive processing of emotions on perceptual decision making remains poorly understood. Here,(More)
BACKGROUND Patients with a narcissistic personality disorder (NPD) do not often consult a psychotherapist or psychiatrist because of their NPD, but rather, because of co-occurring psychiatric disorders, or higher general symptom stress. Until now there is no actual data about rates of co-occurrence disorders and general symptom stress. OBJECTIVE Which(More)
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.(More)
BACKGROUND AND OBJECTIVES Narcissistic personality disorder (NPD) is characterized by reports of grandiosity including exaggerated illusions of superiority and entitlement (DSM-IV-TR, APA, 2000). Based on clinical theories (e.g., Kernberg, 1975), many researchers argue that high explicit self-esteem in narcissists masks underlying implicit vulnerability(More)
