元记忆训练（MMT）是改善老年人认知功能的有效训练策略。尽管有这些优点，但由于地点和时间的限制，也有一些限制。这项研究的目的是开发一种基于智能扬声器的MMT程序，并评估该程序对没有认知障碍的老年人的有效性。本研究采用病例对照队列设计。基于智能扬声器的MMT计划包括每天3次培训课程，每周5天，持续8周。每次培训大约需要15分钟。这个程序是使用智能扬声器实现的，而不是人类教练。所有参与者在培训前后完成了简易精神状态检查、主观记忆投诉问卷、言语学习测试、数字广度测试、流畅性测试和简短版的老年抑郁量表。共有60例受试者（MMT组29例，对照组31例）参加了研究。与对照组相比，训练组在延迟自由回忆、数字前向广度、数字后向广度和流畅性测试得分上有显著提高。这项研究证实了基于智能扬声器的MMT在老年人中的有效性。基于家庭智能扬声器的MMT不受位置限制或空间限制，并且可以帮助患有主观认知下降的老年人，而不需要人类专业人员的干预。
Metamemory training (MMT) is a useful training strategy for improving cognitive functioning in the older adult population. Despite the advantages, there are limitations imposed by location and time constraints. This study aimed to develop a smart speaker–based MMT program and evaluate the efficacy of the program in older adults without cognitive impairment. This study used a case-control cohort design. The smart speaker–based MMT program comprised 3 training sessions per day, 5 days a week, for 8 weeks. Each training session took approximately 15 minutes. This program was implemented using smart speakers, not human trainers. All participants completed the Mini-Mental State Examination, Subjective Memory Complaints Questionnaire, Verbal Learning Test, Digit Span Test, fluency tests, and a short-form version of the Geriatric Depression Scale before and after training. A total of 60 subjects (29 in the MMT group and 31 in the control group) participated in the study. The training group showed significant increases in the delayed free recall, digit span forward, digit span backward, and fluency test scores compared with the control group. This study confirmed the efficacy of smart speaker–based MMT in older adults. Home-based smart speaker–based MMT is not limited with respect to location or constrained by space and may help older adults with subjective cognitive decline without requiring intervention by human professionals.
