Thought, language, and communication disorders are among the salient characteristics of schizophrenia. Such impairments are often exhibited in patients' conversations. Researches have shown that assessments of thought disorder are crucial for tracking the clinical patients' conditions and early detection of clinical high-risks. Detecting such symptoms require a trained clinician's expertise, which is prohibitive due to cost and the high patient-to-clinician ratio. In this paper, we propose a machine learning method using Transformer-based model to help automate the assessment of the severity of the thought disorder of schizophrenia. The proposed model uses both textual and acoustic speech between occupational therapists or psychiatric nurses and schizophrenia patients to predict the level of their thought disorder. Experimental results show that the proposed model has the ability to closely predict the results of assessments for Schizophrenia patients base on the extracted semantic, syntactic and acoustic features. Thus, we believe our model can be a helpful tool to doctors when they are assessing schizophrenia patients.
思维、语言和沟通障碍是精神分裂症的显著特征之一。这些损伤通常表现在患者的对话中。研究表明,思维障碍的评估对于跟踪临床患者的病情和早期发现临床高危人群至关重要。检测这些症状需要经过训练的临床医生的专业知识,但由于成本和医患比例高,这是不可行的。在本文中,我们提出了一种基于转换器的机器学习方法,以帮助实现精神分裂症思维障碍严重程度的自动评估。所提出的模型使用职业治疗师或精神科护士与精神分裂症患者之间的文本和语音来预测他们思维障碍的程度。实验结果表明,所提出的模型能够根据提取的语义、句法和声学特征,紧密预测精神分裂症患者评估的结果。因此,我们相信我们的模型可以成为医生评估精神分裂症患者时的有用工具。
