Although a growing body of empirical literature provides some support for the diagnosis of borderline personality disorder (BPD) in youth, little is known about the internal structure of BPD and the performance of the individual diagnostic criteria, especially in younger samples. We used item response theory (IRT) methods to investigate the psychometric properties of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) BPD criteria in a large, population-based sample (n = 6,339) of young adolescents from the United Kingdom (ages 11 to 12). BPD was assessed using the Childhood Interview for DSM-IV Borderline Personality Disorder (CI-BPD; Zanarini, Horwood, Waylen, & Wolke, 2004). A single underlying dimension adequately accounted for covariation among the BPD criteria. Each criterion was found to be discriminating to a degree comparable to what has been reported in adult studies. BPD criteria were most informative within a range of severity of BPD pathology between +1 and +3 standard units. Five criteria were found to exhibit differential item functioning (DIF) between boys and girls. However, DIF balanced out for the total interview score. Despite the controversy associated with applying the borderline construct to youth, the current findings provide psychometric evidence in favor of doing so.
尽管越来越多的实证文献为青少年边缘性人格障碍（BPD）的诊断提供了一些支持，但关于 BPD 的内部结构和个别诊断标准的表现，特别是在年轻样本中，知之甚少。我们使用项目反应理论（IRT）方法，在英国一个由 6339 名年轻青少年组成的大型基于人群的样本（年龄在 11 至 12 岁之间）中，研究了《精神障碍诊断与统计手册》第 4 版（DSM-IV）BPD 标准的心理测量特性。使用儿童 DSM-IV 边缘性人格障碍访谈（CI-BPD；Zanarini、Horwood、Waylen 和 Wolke，2004）来评估 BPD。一个单一的潜在维度充分解释了 BPD 标准之间的共变。每个标准都具有一定程度的区分能力，与成人研究中报告的程度相当。BPD 标准在 BPD 病理严重程度为+1 到+3 个标准单位的范围内最具信息量。发现五个标准在男孩和女孩之间存在项目功能差异（DIF）。然而，对于总访谈分数，DIF 达到了平衡。尽管将边缘结构应用于青少年存在争议，但目前的发现为这样做提供了心理测量证据。
