Exploring Guilt Differences in Grandiose Narcissism, Vulnerable Narcissism, and Malignant Self-Regard.

Narcissistic personality disorder is a heterogeneous and complex pathology which manifests itself very differently in individuals. The aim of the present study was to analyze differences and similarities in morality and sensitivity to feelings of guilt among grandiose narcissism (GN), vulnerable narcissism (VN), and malignant self-regard (MSR). We expected that MSR and VN would be most sensitive to deontological and altruistic guilt, and that MSR and VN would have higher levels of moral standards than GN. A nonclinical sample of 752 participants was evaluated. Results showed a significant association among MSR, VN, and GN. According to our hypothesis, GN turned out to be the one with the lowest association values to guilt measures. Our results demonstrated that MSR is strongly associated with all types of guilt, GN is associated with a substantial lack of guilt, and VN is associated with deontological guilt and self-hate, but not altruistic guilt. Results confirm the relevance of considering and understanding guilt when differentiating GN, VN, and MSR.
