Exploring Pathological Narcissism Within the ICD-11 Model of Personality Disorders Among Croatian Psychiatric Patients.

We aimed to investigate the relationships of ICD-11 personality disorder (PD) severity and five maladaptive personality domains with narcissistic grandiosity and narcissistic vulnerability among 398 Croatian adult psychiatric patients. They completed the following self-report questionnaires: the ICD-11 Personality Disorder Severity Scale, the Personality Assessment Questionnaire for ICD-11, and the Pathological Narcissism Inventory. Narcissistic grandiosity showed meaningful associations with the Disinhibition and Anankastia domains. Conversely, narcissistic vulnerability was significantly more strongly associated with PD severity and the Negative Affectivity domain, and it also showed meaningful associations with the Disinhibition, Anankastia, and Dissociality domains. An even more nuanced picture emerged on the facet-level of pathological narcissism, while some novel findings were obtained pertaining to gender differences in the above-mentioned relations. Future studies utilizing additional multidimensional measures of pathological narcissism and gender-sensitive assessment are warranted. [ABSTRACT FROM AUTHOR]
