The classification of personality disorder (PD) is undergoing a paradigm shift in which categorically defined specific PDs are being replaced by dimensionally defined maladaptive trait domains. To bridge the classificatory approaches, this study attempts to use items from the categorical PD model in DSM-IV to measure the maladaptive trait domains described in DSM-5 Section III/ICD-11. A general population sample comprising 1228 participants completed the Screening Questionnaire of the Structured Clinical Interview for DSM-IV Axis II (SCID-II-SQ), the Personality Inventory for DSM-5 (PID-5), and the anankastia scale of the Personality Inventory for ICD-11 (PiCD). Using item response theory models and a psychometric linking technique, SCID-II-SQ items were evaluated for their contribution to measuring maladaptive trait domains. The best discriminating items were then selected to derive proxy scales. We found that convergent validity of these proxy scales was in a similar range to that of other self-report measures for PD, except for the proxy scale for PiCD anankastia. However, only the proxy scale for negative affectivity showed acceptable reliability that would allow its application in research settings. Future studies should seek to establish a common metric between specific PDs and maladaptive trait domains using self-report measures with higher specificity or semi-structured interviews.

使用通用指标方法，通过 DSM-IV Axis II 筛查问卷的结构化临床访谈来测量适应不良的人格特质

人格障碍 (PD) 的分类正在经历范式转变，其中明确定义的特定 PD 正在被维度定义的适应不良特征域所取代。为了弥合分类方法，本研究尝试使用 DSM-IV 中的分类 PD 模型中的项目来测量 DSM-5 第 III 节/ICD-11 中描述的适应不良特征域。由 1228 名参与者组成的一般人群样本完成了 DSM-IV Axis II 结构化临床访谈筛选问卷 (SCID-II-SQ)、DSM-5 人格量表 (PID-5) 以及人格的 anankastia 量表ICD-11 (PiCD) 库存。使用项目反应理论模型和心理测量链接技术，评估 SCID-II-SQ 项目对测量适应不良特征领域的贡献。然后选择最佳区分项目来得出代理量表。我们发现，除了 PiCD anankastia 的代理量表外，这些代理量表的收敛效度与其他 PD 自我报告测量的收敛效度范围相似。然而，只有负面情感的代理量表显示出可接受的可靠性，可以将其应用于研究环境。未来的研究应该寻求使用具有更高特异性的自我报告措施或半结构化访谈，在特定的PD和适应不良特征领域之间建立一个共同的衡量标准。
