研究目的:

本研究依托豆包大语言模型构建AI干预智能体,将怀旧疗法融入对话式人工智能系统,为孤独老年人提供持续的对话交流与情感支持服务。通过数字化对话干预,旨在评估大语言模型聊天机器人在缓解孤独感、改善抑郁情绪和促进心理健康方面的效果,并比较不同怀旧引导方式的干预差异,为人工智能应用于老年心理健康促进提供实证依据。  

Objectives of Study:

This study develops an AI intervention agent based on the Doubao large language model by integrating reminiscence therapy into a conversational AI system to provide continuous communication and emotional support for lonely older adults. Through a digital conversational intervention, the study aims to examine the effectiveness of large language model–based chatbots in reducing loneliness, alleviating depressive symptoms, and improving psychological well-being, while also comparing the effects of different reminiscence-guidance approaches. The findings are expected to provide empirical evidence for the application of artificial intelligence in promoting mental health among older adults.

Group:

Young-Self Reminiscence Group

Sample size:

干预措施:

参与者与基于大语言模型构建的“虚拟年轻自我智能体”进行语音对话,在互动中围绕自身童年经历、重要生活事件和情感体验等开展怀旧回忆。干预周期为8周,每周3次,每次约10分钟。

干预措施代码:

Intervention:

Participants engage in voice-based conversations with a "virtual younger-self agent" developed on the basis of a large language model. During the interaction, they are guided to engage in reminiscence about their childhood experiences, important life events, and emotional experiences. The intervention lasts for 8 weeks, with 3 sessions per week, and each session lasts approximately 10 minutes.
