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数据集重新编译为一项新的研究成果，该成果于2023年12月发布，编号为ICPSR 38821；数据使用者应改用该编号为38821的研究数据集。独立与健康老年人高级认知训练（ACTIVE, Advanced Cognitive Training for Independent and Vital Elderly）1999-2001年［美国］是一项在6个现场站点开展的多中心随机对照试验，由新英格兰研究所（NERI）担任协调中心。参与本次试验的现场站点包括：阿拉巴马大学伯明翰分校、波士顿希伯来老年康复中心、印第安纳大学、巴尔的摩约翰斯·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）。本试验的核心目标为验证三种已在实验室或小规模现场环境中被证实可改善老年人基础认知测试表现的认知干预手段，对需要认知参与的日常活动指标的影响效果。培训方案分为初始阶段与巩固阶段：初始阶段包含10次小组课程，随后在试验第1年和第3年分别开展4次巩固培训。三种认知干预分别聚焦于记忆力、执行推理能力与信息处理速度。试验设置了无接触对照组。研究对象在基线期、培训结束即刻以及此后每年接受一次评估。本次试验共招募2832名老年参与者，最终纳入分析样本的为2802人，其中26%的参与者为非裔美国人。
