Borderline personality disorder (BPD) is frequently conceptualized as an extreme variant of normal personality traits. A previous study successfully developed and validated a self-report BPD measure, the Minnesota Borderline Personality Disorder Scale (MBPD). We conducted 2 studies aimed at providing further validation for this measure. Results from Study 1 (clinical sample of substance users) indicated that the MBPD exhibited strong positive correlations with measures of convergent validity. In addition, the MBPD showed similar correlations with external correlates as those of the convergent validity measures as well as incremental utility in predicting these external correlates above and beyond negative affect and adult antisocial behavior. Also, a receiver operating characteristic curve analysis indicated that diagnostic accuracy of the MBPD was excellent for differentiation between BPD and non-BPD individuals. Likewise, Study 2 (nonclinical sample of undergraduate students followed over 6 months) showed strong correlations with an index of convergent validity, similar correlations with external correlates as that of the convergent validity index, and incremental predictive utility. Finally, in this study, the MBPD exhibited high rank-order stability. These data provide further evidence that the MBPD is a valid indicator of BPD.
边缘性人格障碍(BPD)常被视为正常人格特质的极端变体。此前一项研究成功开发并验证了一种边缘性人格障碍的自评量表——明尼苏达边缘性人格障碍量表(MBPD)。我们开展了两项研究,旨在为该量表提供进一步验证。研究1(物质使用者临床样本)的结果表明,MBPD与收敛效度测量指标呈现出强正相关。此外,MBPD与外部相关因素的相关性,与收敛效度测量指标的相关性相似,并且在预测这些外部相关因素方面,相对于消极情绪和成人反社会行为具有增量效用。同时,一项受试者工作特征曲线分析表明,MBPD在区分边缘性人格障碍患者与非边缘性人格障碍患者方面诊断准确性极佳。同样,研究2(对本科生进行6个月跟踪的非临床样本)显示,MBPD与收敛效度指标具有强相关性,与外部相关因素的相关性与收敛效度指标相似,且具有增量预测效用。最后,在本研究中,MBPD表现出高度的等级稳定性。这些数据进一步证明MBPD是边缘性人格障碍的有效指标。
