Comprehensive evaluation of PTSD includes diagnostic interviews, self-report testing, and physiological reactivity measures. It is often difficult and costly to diagnose PTSD due to patient access and the variability in symptoms presented. Additionally, potential patients are often reluctant to seek help due to the stigma associated with the disorder. A voice-based automated system that is able to remotely screen individuals at high risk for PTSD and monitor their symptoms during treatment has the potential to make great strides in alleviating the barriers to cost effective PTSD assessment and progress monitoring. In this paper we present a voice-based automated Tele-PTSD Monitor (TPM) system currently in development, designed to remotely screen, and provide assistance to clinicians in diagnosing PTSD. The TPM system can be accessed via a Public Switched Telephone Network (PSTN) or the Internet. The acquired voice data is then sent to a secure server to invoke the PTSD Scoring Engine (PTSD-SE) where a PTSD mental health score is computed. If the score exceeds a predefined threshold, the system will notify clinicians (via email or short message service) for confirmation and/or an appropriate follow-up assessment and intervention. The TPM system requires only voice input and performs computer-based automated PTSD scoring, resulting in low cost and easy field-deployment. The concept of the TPM system was supported using a limited dataset with an average detection accuracy of up to 95.88%.
创伤后应激障碍（PTSD）的综合评估包括诊断访谈、自我报告测试和生理反应测量。由于患者就诊机会以及所呈现症状的变异性，PTSD的诊断往往既困难又昂贵。此外，潜在患者常常因与该疾病相关的污名而不愿寻求帮助。一个基于语音的自动化系统，能够远程筛查PTSD高危个体并在治疗期间监测其症状，有可能在消除经济高效的PTSD评估和进展监测障碍方面取得巨大进展。在本文中，我们介绍了一个目前正在开发的基于语音的自动化远程PTSD监测器（TPM）系统，旨在远程筛查并协助临床医生诊断PTSD。TPM系统可通过公共交换电话网络（PSTN）或互联网访问。然后，获取的语音数据被发送到安全服务器以调用PTSD评分引擎（PTSD-SE），在那里计算出PTSD心理健康评分。如果分数超过预定义阈值，系统将通知临床医生（通过电子邮件或短信服务）进行确认和/或进行适当的后续评估及干预。TPM系统仅需要语音输入，并执行基于计算机的自动化PTSD评分，成本低且易于现场部署。使用一个有限的数据集对TPM系统的概念进行了验证，平均检测准确率高达95.88%。
