Abstract

The significance of early maladaptive traits for understanding the roots of borderline personality disorder (BPD) is increasingly endorsed. Given the interpersonal nature of BPD and fluctuations in phenotypic symptomatology, this study aims to test the assumption that a situation-contingent contextualized assessment of borderline traits is a viable avenue to more fully capture the way underlying traits are reflected in socioaffective behavior that occurs in age-relevant situations. We aimed to explore the extent to which the variability on these responses represents a meaningful construct for understanding the clinical richness of BPD. Toward this end, a contextualized measure of DSM–5 BPD traits was developed along a situational judgment test (SJT) format, allowing us to explore both between-person and within-person variability in a more economic format than repeated measurement does. Examination of the psychometric properties of the SJT revealed distinctive correlational patterns of the situation-based traits with symptom scales of a youth BPD measure, but also indicated that for certain traits consistency in trait level across different situations is more maladaptive, whereas for other traits a greater degree of variability in trait expression is more maladaptive. Overall, this work could set the stage for further research on the potential of SJTs for understanding personality vulnerabilities both at the dispositional and the dynamic level.

早期适应不良特征对于理解边缘型人格障碍（BPD）根源的重要性越来越受到认可。考虑到 BPD 的人际本质和表型症状学的波动，本研究旨在检验这样的假设：对边缘特征进行情境情境化评估是更全面地捕捉潜在特征在年龄发生的社会情感行为中反映的方式的可行途径。 -相关情况。我们的目的是探讨这些反应的变异性在多大程度上代表了理解 BPD 临床丰富性的有意义的构建。为此，我们按照情境判断测试 (SJT) 格式开发了DSM-5 BPD 特征的情境化测量，使我们能够以比重复测量更经济的格式探索人与人之间和人内部的变异性。对 SJT 心理测量特性的检查揭示了基于情境的特征与青少年 BPD 测量的症状量表的独特相关模式，但也表明，对于某些特征，不同情况下特征水平的一致性更不适应，而对于其他特征，性状表达的变异程度越大，适应性就越差。总的来说，这项工作可以为进一步研究 SJT 在理解性格和动态层面上的人格弱点的潜力奠定基础。
