Abstract:

Objective To conduct a scoping review of the application of multimodal fusion technology in the management of psychological symptoms among older adults，so as to provide evidence for the application of this technology in gerontological psychological nursing. Methods Based on the methodological framework of a scoping review，systematic literature searches were performed across PubMed，Web of Science，IEEE Xplore，PsycINFO，Scopus，China National Knowledge Infrastructure，Wanfang Database，VIP Database，and SinoMed. The search period spanned from the inception of each database to May 30，2026. Data extraction and narrative synthesis were carried out for the included studies. Results A total of 23 studies published between 2017 and 2026 were included，originating from China，South Korea，the United States，and other countries. The data types covered behavioral data，physiological signals，speech and language data，environmental context data，selfreported data，demographic information，and healthrelated data. Primary collection devices included wearable devices，ambient sensors，and audio capture devices. Depressive symptoms and loneliness were the most frequently studied outcomes，while less attention was paid to psychological symptoms such as anxiety and apathy. The main application domain was psychological symptom assessment，with some studies extending to dynamic monitoring and psychological intervention. Fusion strategies were evolving from feature level concatenation toward deeper interactive approaches such as attention mechanisms. Conclusion Multimodal fusion technology shows potential for assessing psychological symptoms in older adults. However，most existing studies are small sample exploratory studies with limited coverage of psychological symptoms. Future efforts should expand assessment dimensions，strengthen privacy and ethical governance，and promote the translation of relevant technologies into nursing practice.

摘要：

目的 对多模态融合技术在老年人心理症状管理中应用的研究进行范围综述，以期为该技术在老年心理护理领域的实践提供参考。 方法 依据范围综述方法框架，系统检索PubMed、Web of Science、IEEE Xplore、PsycINFO、Scopus、中国知网、万方数据库、维普数据库、中国生物医学文献数据库，检索时限为建库至2026年5月30日，对纳入文献进行数据提取和汇总分析。 结果 共纳入23篇文献，发表时间为2017—2026年，来源于中国、韩国、美国等多个国家。数据类型涵盖行为数据、生理信号、语音语义数据、环境情境数据、自报告数据、人口学资料及健康相关数据。采集设备主要包括可穿戴设备、环境情境传感器及语音采集设备等。抑郁症状和孤独感是最常见的研究结局，焦虑、淡漠等心理症状关注较少。应用环节以心理症状评估为主，部分研究拓展至动态监测和心理干预。融合策略正从特征层拼接向注意力机制等深层交互方向演进。 结论 多模态融合技术在老年人心理症状评估中展现出良好的应用潜力，但现有研究多为小样本探索性研究，心理症状覆盖范围有限。未来应扩大评估维度、完善隐私与伦理治理，并推动相关技术向护理实践转化。
