title: Development and validation of the Minnesota borderline personality disorder scale.
abstract: Although large epidemiological data sets can inform research on the etiology and development of borderline personality disorder (BPD), they rarely include BPD measures. In some cases, however, proxy measures can be constructed using instruments already in these data sets. In this study, the authors developed and validated a self-report measure of BPD from the Multidimensional Personality Questionnaire (MPQ). Items for the new instrument-the Minnesota BPD scale (MBPD) -were identified and refined using three large samples: undergraduates, community adolescent twins, and urban substance users. The authors determined the construct validity of the MBPD scale by examining its association with (a) diagnosed BPD, (b) questionnaire-reported BPD symptoms, and (c) clinical variables associated with BPD: suicidality, trauma, disinhibition, internalizing distress, and substance use. The authors also tested the MBPD scale in two prison inmate samples. Across samples, the MBPD scores correlated with BPD indices and external criteria and showed incremental validity above measures of negative affect, thus supporting its construct validity as a measure of BPD.
