The length and expense of comprehensive personality disorder interviews makes them unwieldy for routine use. A brief but sensitive screen could eliminate administration of longer instruments in many instances. We describe the development of the Iowa Personality Disorder Screen (IPDS)--a mini-structured interview which can be completed in less than 5 minutes. Retrospective analyses using 1,203 SIDP-R interviews suggested that the IPDS items should provide good sensitivity and specificity. We present results from a prospective validation study, using a mixed group of 52 nonpsychotic inpatients and outpatients who were diagnosed using the SIDP-IV. Blind administration of the IPDS yielded excellent sensitivity (92%) and good specificity (79%), using a subset of five screening items. Addition of two more items leads to an estimated sensitivity of 79% and specificity of 86%. The IPDS shows promise as a quick personality disorder screen for use in research settings or standard clinical interviews.
全面性人格障碍访谈的时长和成本使其在常规使用中不太方便。在许多情况下，一个简短但灵敏的筛查工具可以避免使用更长的测评工具。我们描述了爱荷华人格障碍筛查量表（IPDS）的开发过程——这是一种小型结构化访谈，可在不到5分钟内完成。使用1203次结构性访谈诊断人格障碍量表（SIDP-R）进行的回顾性分析表明，IPDS的项目应具有良好的敏感性和特异性。我们展示了一项前瞻性验证研究的结果，该研究使用了一组52名非精神病性住院患者和门诊患者的混合样本，这些患者使用结构性访谈诊断人格障碍量表第四版（SIDP-IV）进行诊断。使用五个筛查项目的子集对IPDS进行盲法施测，其敏感性极佳（92%），特异性良好（79%）。再增加两个项目后，估计敏感性为79%，特异性为86%。IPDS有望成为一种用于研究环境或标准临床访谈的快速人格障碍筛查工具。
