Narcissistic Implications in Gambling Disorder: The Mediating Role of Emotion Dysregulation.

Gambling Disorder (GD) is a complex psychopathology involving a numbers of cognitive, behavioral, emotional and neurobiological determinants. Previous research suggests that GD may frequently co-occur with Narcissistic Personality Disorder. However, there is still a lack of study investigating Pathological Narcissism (PN) in both its vulnerable and grandiose facets among clinical population. Moreover, emotional dysregulation is commonly thought to underlie GD albeit research on this topic remains poor. The present study aims to investigate the role of both vulnerable and grandiose narcissism in relation to GD as well as the mediator role played by emotion dysregulation in such link. We administered to a sample of addicted gamblers (n = 74) and a sample of heathy controls (n = 105), the South Oaks Gambling Screen (SOGS), the Pathological Narcissism Inventory (PNI) and the Difficulties in Emotion Regulation Scale (DERS). Differences across groups emerged on the scores obtained on the PNI and DERS. Moreover, we found positive associations between SOGS scores and both PNI and DERS. Also, strategic addicted gamblers showed higher levels of vulnerable narcissism compared to others. Finally, emotion dysregulation difficulties appeared to fully mediate the relationship between grandiose narcissism and GD severity. Grandiose and vulnerable narcissism appear important variables involved in GD. Also, emotion regulation deficits seem to account for GD and to explain the pathways by which grandiose narcissism leads to GD. Clinical implications and future directions are discussed.
