本文总结了运用项目反应理论（IRT）模型对边缘型人格障碍DSM诊断标准进行分析的结果。研究样本包括353名参与者，其中大多数是精神病患者。验证性因子分析表明，单因素模型对数据的拟合效果最好。所有DSM BPD标准均具有中等或较高的项目区分参数，表明所有项目都为评估BPD提供了有意义的信息。项目信息函数显示，总体而言，BPD标准对捕获中度至重度BPD特征有用，但在轻度BPD特征中表现不佳。总的结论是，这些标准确实代表了一种连贯的综合征，对个别标准的信息价值进行进一步研究将是有用的。
This paper summarizes results from analyses of the DSM criteria for borderline personality disorder (BPD) using models from item response theory (IRT). The study sample consisted of 353 participants, the majority of whom were psychiatric patients. Confirmatory factor analysis showed that a one-factor model provided the best fit to the data. All the DSM BPD criteria had moderate or higher item discrimination parameters, indicating that all items contributed meaningful information in assessing BPD. Item information functions revealed that the BPD criteria as a whole were useful for capturing BPD traits in the moderately severe to severe range, but that they performed less well in the less severe range. The general conclusion is that the criteria do represent a coherent syndrome and that further research on the informational value of the individual criteria would be useful.
