This study sought to further delineate the attributes comprising the Borderline personality disorder. Fifty-four clinicians had 309 patients complete a Millon Clinical Multiaxial Inventory and the clinician completed a Millon Diagnostic Personality Schedule as well as a DSM-III diagnosis on each of these 309 patients.A high degree of convergence was found among all three assessment approaches as assessed by sensitivity and specificity measures as well as analyses of mean base rate scores on the MCMI and MDPS. In regard to individual attributes, affective expression, interpersonal style and behavior demonstrated the highest levels of sensitivity and specificity among the attributes hypothesized to demonstrate high levels. Behavior attained the highest level of predictive power overall, followed by cognitive style and affective expression. Notable was the very high level of positive predictive power obtained by the intrapsychic organization attribute.The Borderline personality disorder was found to covary with the passive-aggressive, avoidant and histrionic personalities with greater frequencies than it did with other personality disorders. No bias was found in relation to theoretical orientation among the clinicians in regard to their utilization of the diagnostic attributes. Those individuals who received the diagnosis of Borderline personality disorder were shown to be significantly younger than those receiving all other diagnoses and females were twice as likely to be diagnosed Borderline than were males.The findings of this study provided a definitive explication of the attributes of the Borderline personality disorder. Not only were the hypotheses strongly confirmed, but the pattern and direction of each of the major findings lent themselves to reasonably logical interpretations, as well.
