背景资料：精神病诊断筛查问卷（PDSQ）是一种简短的、心理测量学上强大的自我报告量表，旨在筛查门诊心理健康环境中遇到的最常见的DSM-IV轴I障碍。在本报告中，我们描述的诊断性能（敏感性，特异性，阳性和阴性预测值）的PDSQ在门诊setting.Methods：六百三十精神科门诊病人提出治疗进行了评估，结构化临床访谈DSM-IV完成后的PDSQ。患者在预约时间前约20分钟到达以完成量表。诊断率是盲目的反应scale.Results：PDSQ的分量表的诊断性能变化在一个可预测的方式根据截止得分的阈值为情况下识别增加，子量表的灵敏度下降，特异性增加。平均子量表灵敏度为80%、85%和90%，平均子量表特异性分别为78%、73%和66%，阴性预测值分别为95%、96%和97%。受试者工作曲线确定每个子量表和曲线下的所有区域显着。结论：PDSQ是一种诊断援助，旨在用于临床实践中，以促进效率进行初步诊断评估。从临床角度来看，最重要的是诊断辅助工具具有良好的灵敏度，以便检测到大多数病例，以及高阴性预测值，以便测量的大多数非病例确实是非病例。我们的研究结果表明，大多数PDSQ分量表能够实现这一目标。
Background: The Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a brief, psychometrically strong, self-report scale designed to screen for the most common DSM-IV Axis I disorders encountered in outpatient mental health settings. In the present report, we describe the diagnostic performance (sensitivity, specificity, and positive and negative predictive values) of the PDSQ in an outpatient setting.Methods: Six hundred thirty psychiatric outpatients presenting for treatment were evaluated with the Structured Clinical Interview for DSM-IV after completing the PDSQ. Patients arrived approximately 20 minutes before the scheduled time of the appointment to complete the scale. Diagnostic raters were blind to responses on the scale.Results: The PDSQ's subscales' diagnostic performance varied in a predictable manner according to the cutoff score-as the threshold for case identification increased, subscale sensitivity decreased and specificity increased. Mean subscale sensitivities of 80%, 85%, and 90% resulted in mean subscale specificities of 78%, 73%, and 66%, respectively, and negative predictive values of 95%, 96%, and 97%. Receiver operating curves were determined for each subscale and all areas under the curve were significant.Conclusions: The PDSQ is a diagnostic aid designed to be used in clinical practice to facilitate the efficiency of conducting initial diagnostic evaluations. From a clinical perspective, it is most important that a diagnostic aid have good sensitivity, so that most cases are detected, and high negative predictive value, so that most noncases on the measure are indeed noncases. Our results indicate that most of the PDSQ subscales were able to achieve this goal.
