研究目的:

本研究旨在评估自适应工作记忆训练对精神分裂症患者执行功能的改善效果,并使用机器学习方法量化患者执行功能谱沿精神病-健康连续体的变化。主要目的包括:(1)评估自适应N-back工作记忆训练相比于非自适应训练和常规治疗在改善精神分裂症患者执行功能方面的疗效;(2)使用支持向量机分类器量化干预后患者执行功能谱向健康对照组谱系的转移程度;(3)通过整合因果推断与机器学习方法,识别预测治疗反应的基线因素,为精准精神医学和个体化认知干预提供科学依据。  

Objectives of Study:

This study aims to evaluate the efficacy of adaptive working memory training on executive functions in patients with schizophrenia and quantify changes in executive function profiles along the psychosis-health continuum using machine learning approaches. The primary objectives include: (1) to assess the effectiveness of adaptive N-back working memory training compared to non-adaptive training and treatment-as-usual in improving executive functions in schizophrenia patients; (2) to quantify the degree to which patients' executive function profiles shift toward those of healthy controls following intervention using support vector machine classifiers; (3) to identify baseline predictors of treatment response by integrating causal inference with machine learning methods, thereby providing scientific evidence for precision psychiatry and individualized cognitive interventions.
