Previous research indicates that borderline personality disorder (BPD) is well conceptualized as a dimensional construct that can be represented using normal personality traits. A previous study successfully developed and validated a BPD measure embedded within a normal trait measure, the Minnesota Borderline Personality Disorder Scale (MBPD). The current study performed a further validation of the MBPD by examining its convergent validity, external correlates, and heritability in a sample of 429 female twins. The MBPD correlated strongly with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) screener for BPD and moderately with external correlates. Moreover, the MBPD and SCID-II screener exhibited very similar patterns of external correlations. Additionally, results indicated that the genetic and environmental influences on MBPD overlap with the genetic and environmental influences on the SCID-II screener, which suggests that these scales are measuring the same construct. These data provide further evidence for the construct validity of the MBPD.
先前的研究表明，边缘型人格障碍（BPD）可以很好地被概念化为一个维度结构，可以用正常的人格特质来表示。先前的一项研究成功地开发并验证了一种 BPD 测量方法，该方法嵌入在正常特质测量中，即明尼苏达边缘型人格障碍量表（MBPD）。本研究通过对 429 名女性双胞胎样本进行一致性检验、外部相关性和遗传度检验，进一步验证了 MBPD。MBPD 与 DSM-IV 轴 II 人格障碍的结构性临床访谈（SCID-II）筛查器的 BPD 高度相关，与外部相关性中度相关。此外，MBPD 和 SCID-II 筛查器的外部相关性模式非常相似。此外，研究结果表明，MBPD 的遗传和环境影响与 SCID-II 筛查器的遗传和环境影响重叠，这表明这些量表测量的是同一结构。这些数据为 MBPD 的建构效度提供了进一步的证据。
