Reliability and convergence of three concepts of narcissistic personality

UNTIL recent years, the personality disorders have been relatively unexplored compared to other psychiatric diagnoses. Over 15 years ago, there was little agreement on the diagnosis of borderline personality disorder (Ferry and Klerman 1978), but efforts to specify the constructs and respective criteria for the borderline diagnosis spurred a plethora of systematic research, The result is that, next to antisocial personality disorder, borderline has become one of the best-documented and validated personality disorders (Ferry and Vaillant 1989), One important shift has been that good descriptive studies have gradually led to studies of etiological factors, such as childhood physical and sexual abuse, and severe neglect (Herman et al, 1989; Ferry and Herman 1992), which in turn have led to empirically based treatment approaches (Herman 1992; Ferry et al. 1990), Despite inclusion in The Diagnostic and Statistical Manual of Mental Disorders (DSM-III and DSM-III-R), narcissistic personality is still at the beginning of this process of description, empirical testing, and validation (Gunderson et al. 1991). This study empirically examines three descriptions of narcissistic personality in order to look for common underlying dimensions that may have etiological and treatment significance.
