AI总结:

针对抑郁症诊断训练数据不足,提出临床医生参与的LLM患者模拟流水线TalkDep,生成符合诊断标准的多样化症状,经临床验证以提升自动诊断系统的鲁棒性。

摘要:

心理健康服务需求的日益增长已超过用于培养临床专业人员的真实训练数据的可用性,导致抑郁症诊断支持受限。这一短缺推动了模拟或虚拟患者的开发以辅助训练和评估,但现有方法往往无法生成临床有效、自然且多样化的症状表现。在本工作中,我们采用近期先进的语言模型作为基础,提出了一种新颖的临床医生参与的患者模拟流水线TalkDep,通过获取多样化的患者档案来开发模拟患者。通过将模型条件化于精神科诊断标准、症状严重程度量表和情境因素,我们的目标是创建真实的患者反应,以更好地支持诊断模型的训练和评估。我们通过临床专业人员进行的全面评估验证了这些模拟患者的可靠性。经验证的模拟患者的可用性为提升自动抑郁症诊断系统的鲁棒性和泛化性提供了可扩展且适应性强的资源。

英文摘要:

The increasing demand for mental health services has outpaced the availability of real training data to develop clinical professionals, leading to limited support for the diagnosis of depression. This shortage has motivated the development of simulated or virtual patients to assist in training and evaluation, but existing approaches often fail to generate clinically valid, natural, and diverse symptom presentations. In this work, we embrace the recent advanced language models as the backbone and propose a novel clinician-in-the-loop patient simulation pipeline, TalkDep, with access to diversified patient profiles to develop simulated patients. By conditioning the model on psychiatric diagnostic criteria, symptom severity scales, and contextual factors, our goal is to create authentic patient responses that can better support diagnostic model training and evaluation. We verify the reliability of these simulated patients with thorough assessments conducted by clinical professionals. The availability of validated simulated patients offers a scalable and adaptable resource for improving the robustness and generalisability of automatic depression diagnosis systems.
