ABSTRACT
While frequently the topic of psychodynamic theorizing, the empirical research literature on the narcissistic and histrionic PDs remains scarce. Accordingly, definite statements about their specific aetiology, course, and treatment response are currently suspect. For the narcissistic personality disorder, the official DSM criteria are discussed, along with the influential theoretical accounts of Kohut, Kernberg, Millon, and Young. A distinction is introduced between the overt and the covert narcissist. For histrionic personality disorder, the evidence is even more limited. Gender issues and diagnostic relevant issues are briefly reviewed. Finally, recognizing the extensive comorbidity characterizing Cluster B personality disorders, several researchers have lumped the disorders together and examined key correlates (such as interpersonal violence) at the cluster level rather than at the level of the comprising separate disorders.
