moreThe authors present preliminary psychodynamic findings from a naturalistic study of borderline personality disorder compared to antisocial personality disorder and bipolar type II (depression with hypomania) affective disorder. An independent psychodynamic interview of each subject was videotaped from which ratings were made of the presence of 22 defense mechanisms and 11 psychodynamic conflicts. A factor analysis of ratings from 81 subjects supported the separation of borderline (splitting, projective identification) from narcissistic defenses (devaluation, omnipotence, idealization, mood-incongruent denial). While certain groups of defenses were associated with each diagnosis, defense ratings did not significantly discriminate the three diagnostic groups, suggesting a limit to their diagnostic value. Among 27 subjects rated, borderline personality was strongly associated with two conflicts: separation-abandonment, and a global conflict over the experience and expression of emotional needs and anger. Antisocial personality was psychodynamically distinct and more heterogeneous. Bipolar type II was associated with two hypothesized depressive conflicts: dominant other and dominant goal. Chronic depression, which was more common in both personality disorder groups than in bipolar type II, was associated with a third depressive conflict, overall gratification inhibition. Overall, conflicts were powerful discriminators of the three diagnostic groups. The heuristic value of these findings is discussed. FOR THE PAST SEVERAL YEARS we have been conducting a study of the psychopathology and course of borderline personality disorder to determine whether this diagnosis is valid and can be discriminated from other disorders. We selected two near neighbor disorders for this comparison on which there has been systematic research. We chose antisocial personality disorder because of a possible overlap in impulse pathology, and bipolar type II affective disorder because recurrent depression and hypomania represent disturbances in affect regulation which may overlap with borderline personality disorder. To determine the discriminate validity of borderline personality disorder from these two comparison disorders, we have examined descriptive features, and the prevalence of accompanying syndromes such as depression, alcohol, and drug abuse. We are following their course for patterns of impulse problems, social role dysfunction, and response to life events (Perry 1985); (Perry and Cooper 1985). In addition to this descriptive work, we are systematically examining the psychodynamics of these disorders using a framework of defense mechanisms and psychodynamic conflicts, ascertained outside of psychoanalytic or other treatment contexts. This preliminary report addresses the question of whether the borderline personality disorder is associated with psychodynamics that differentiate it from these two comparison disorders. The psychodynamic literature has generally viewed the antisocial and borderline personality disorders as strongly related or even identical regarding their underlying psychodynamics. Kernberg (1975) stated that most cases of antisocial personality disorder have an underlying borderline personality organization. This concept is defined by the presence of intact reality testing, identity diffusion, and the use of certain primitive defenses revolving around splitting, which defend against the activation of pathological internalized object relations (Kernberg, 1981). Kernberg has suggested that the major deficit in borderline psychopathology is the inability to integrate positive and negative identifications and introjects. The reliance
