在大多数监狱人口中，人格障碍的发病率很高。许多人通过系统未确诊。筛查工具将改善识别。本研究探讨了人格诊断问卷-4+（PDQ-4+）在暴力和性犯罪的囚犯被定罪的筛选性能。英国囚犯的样本完成了自我报告PDQ-4+，并使用DSM-IV轴II障碍的结构化临床访谈进行了采访。当用于生成总分时，PDQ-4+具有可接受的总体准确性，如通过受试者操作特征（ROC）曲线下面积测量的。PDQ-4+似乎具有适合用作筛查工具的特性，特别是在筛查人格障碍的存在或不存在而不是个体人格障碍类别时。给出了一个图表，从中可以选择灵敏度和特异性不同组合的临界值。25分或以上的截止总分产生接近最佳的灵敏度和特异性。该人群的建议临界值低于先前建议的临界值。
There is a high prevalence of personality disorder in most prison populations. Many pass through the system undiagnosed. A screening instrument would improve identification. This study examined the screening properties of the Personality Diagnostic Questionnaire-4+ (PDQ-4+) in prisoners convicted of violent and sexual offences. A sample of British prisoners completed the self-report PDQ-4+ and were interviewed using the Structured Clinical Interview for DSM-IV Axis II disorders. When used to generate a total score, the PDQ-4+ had an acceptable overall accuracy as measured by the area under the Receiver Operating Characteristics (ROC) curve. The PDQ-4+ appears to have the properties suit able for use as a screening instrument, particularly when screening for the presence or absence of personality disorder rather than for individual personality disorder categories. A graph is presented from which choices of cut-off score for different combinations of sensitivity and specificity can be made. A cut off total score of 25 or above yielded near optimal sensitivity and specificity. The suggested cut off score for this population is lower than that previously suggested.
