We previously developed a three-item screener for identifying respondents with any personality disorder (PD) using the Inventory of Interpersonal Problems (IIP). The current goal was to examine the convergent validity of the IIP-3 with other PD screeners and diagnostic tools and to investigate its relationship to measures of adult attachment and emotion regulation. The sample consisted of participants from five studies (total N = 852), with data from collateral informants available for a subsample (N = 353). Despite its brevity, the IIP-3 showed moderate to strong relationships with other longer PD screeners, with PD symptom scores from the Structured Interview for DSM-IV Personality (SIDP-IV), and with a global rating of PD severity. It was most sensitive to the stylistic aspects of PD typical of the traditional DSM cluster B (dramatic, expressive) PDs. These results emerged with data from both participants and informants, although correlations using informant data were generally smaller.

从人际关系问题清单 (IIP-3) 验证人格障碍的三项筛选器。

我们之前开发了一个三项筛选器，用于使用人际关系问题清单 (IIP) 来识别患有任何人格障碍 (PD) 的受访者。当前的目标是检查 IIP-3 与其他 PD 筛查工具和诊断工具的收敛效度，并研究其与成人依恋和情绪调节措施的关系。样本包括来自五项研究的参与者（总 N = 852），子样本（N = 353）提供了来自附属线人的数据。尽管很简短，但 IIP-3 与其他较长的 PD 筛查工具显示出中等至强的关系，其 PD 症状评分来自 DSM-IV 人格结构化访谈 (SIDP-IV)，以及 PD 严重程度的全球评级。它对传统 DSM 集群 B 典型的 PD 风格方面最为敏感（戏剧性、表达）PD。这些结果来自参与者和线人的数据，尽管使用线人数据的相关性通常较小。
