Emotion dysregulation acts in the relationship between vulnerable narcissism and suicidal ideation.

Suicide behaviors are peculiar aspects of several cluster B disorders, including Narcissistic Personality Disorder. To date, it is still unclear which facet of narcissism is more related to the desire to die and which other factors are involved in this relationship. This study aims to offer preliminary empirical evidences concerning the relationship between narcissism, emotion dysregulation and suicide ideation. We administered the Pathological Narcissism Inventory (PNI), Difficulties in Emotion Regulation Scale (DERS), PID-5-BF (Personality Inventory for DSM-5-Short Form) and Beck Scale for Suicide ideation (BSI) to a sample of individuals with suicide ideation (n = 70) and a sample of community participants (n = 154). Controlling for age, gender and Negative Affectivity, we found that BSI scores correlated significantly with the vulnerable dimension of narcissism, but not with the grandiose one, and with all DERS dimension, apart from Awareness. Nevertheless, emotion dysregulation moderates the relationship between vulnerable narcissism and suicide ideation. Suicide ideation seems to be deeply connected with the vulnerable dimension of pathological narcissism and the relationship between the constructs is totally mediated by emotion dysregulation. Future directions and clinical implications are discussed.
