Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE), United States, 1999-2001

The data producers have recompiled the ACTIVE data into a new study which is available as of December 2023, ICPSR 38821; data users should plan to use study 38821 instead. ACTIVE (Advanced Cognitive Training for Independent and Vital Elderly), 1999-2001 [United States] was a multisite randomized controlled trial conducted at six field sites with New England Research Institutes (NERI) as the coordinating center. The field sites included the University of Alabama at Birmingham, Hebrew Rehabilitation Center for the Aged in Boston, Indiana University, Johns Hopkins University in Baltimore, Pennsylvania State University, and the University of Florida/Wayne State University (Detroit). The primary aim of the trial was to test the effects of three distinct cognitive interventions -- previously found to be successful in improving elders' performance on basic measures of cognition under laboratory or small-scale field conditions -- on measures of cognitively demanding daily activities. Trainings consisted of an initial series of ten group sessions followed by four-session booster trainings at one and three years. The three cognitive interventions focused on memory, executive reasoning, and speed of processing. The design included a no-contact control group. Participants were assessed at baseline, immediately after training, and annually thereafter. A total of 2,832 older adults were enrolled in the trial, and 2,802 were included in the analytical sample. Twenty-six percent of the participants were African American.

数据生产者已将ACTIVE数据重新编译成一项新的研究，该研究自2023年12月起可用，ICPSR编号为38821；数据使用者应计划使用38821号研究。ACTIVE（针对独立和活力老年人的高级认知训练，1999-2001年[美国]）是一项在六个现场站点进行的多中心随机对照试验，由新英格兰研究学院（NERI）作为协调中心。现场站点包括阿拉巴马大学伯明翰分校、波士顿的希伯来老年人康复中心、印第安纳大学、巴尔的摩的约翰霍普金斯大学、宾夕法尼亚州立大学以及佛罗里达大学/韦恩州立大学（底特律）。试验的主要目标是测试三种不同的认知干预措施（此前发现能有效提高老年人在实验室或小规模现场条件下的认知基本指标）对认知要求较高的日常活动指标的影响。训练包括一系列十次初始的团体会议，随后在一年和三年时进行四次强化训练。三种认知干预措施分别针对记忆力、执行推理和数据处理速度。研究设计包括一个无接触对照组。参与者在基线、训练后立即以及此后每年进行评估。共有2,832名老年参与者被纳入试验，其中2,802名被纳入分析样本。26%的参与者为非裔美国人。
