ACTIVE (Advanced Cognitive Training for Independent and Vital Elderly), 1999-2008 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 Senior Life (formerly Hebrew Rehabilitation Center for the Aged) in Boston, Indiana University, Johns Hopkins University in Baltimore, Pennsylvania State University, and Wayne State University (Detroit). Data in this study are drawn from measures of cognitively demanding daily activities performed by participants who received a variety of cognitive interventions. Measures included both cognitive functioning (memory, inductive reasoning, speed processing, and general knowledge) and daily functioning (everyday problem solving, observations of daily living, complex reaction time, and general functional ability). Secondary to these measures, the study also includes data on health care and service utilization, driving habits, and mobility. Data were collected at the start of the study (baseline) as well as one, two, three, five, and ten years into the study. This collection includes the data from the tenth year of the study as well as a comprehensive analytical dataset, incorporating data from the previous collections (data from previous waves of the study as well as participant demographic data can be found in ICPSR 4248). 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.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

Scope of Study
Universe: Americans age 65 years or older living in or near one of six study regions (Baltimore, Birmingham, Boston, Detroit, Indianapolis, or State College) who lived without formal care at the point of entry into the study but who were at risk of losing functional independence
This collection is drawn from the tenth year of the ACTIVE study. Please see ICPSR 4248 ACTIVE, 1999-2001 [United States] for data from previous years.
For analysis, the variable AID can be used to link the 23 datasets in this collection as well as the 43 datasets in ICPSR 4248 ACTIVE, 1999-2001 [United States].

Study Purpose: The scientific goal of the trial was to test the effect of three cognitive training programs on improving both cognitive function and the ability to perform certain daily tasks that rely on mental abilities.
Study Design: The design for ACTIVE was a randomized control trial. Subjects were randomly assigned to one of three treatment groups: (1) Memory training; (2) Reasoning training; (3) Speed of Processing training; or (4) no training (control). The interventions occurred in replications, with each replication taking approximately 16-18 weeks. All subjects were assessed at baseline, immediately after the intervention period (post-test), and then at 12-months and 24-months. Booster sessions for each of the three training interventions are conducted within 45 days before the 12-month assessment. Phase II consisted of an assessment at 60 months following completion of training. Phase III consisted of an assessment at 120 months following completion of training. This study provides the data from Phase III activities.
Sample: The sample consisted of 2,832 persons aged 65 to 94 recruited from 6 metropolitan areas in the United States. The University of Alabama at Birmingham (UAB) recruited participants from residents of Jefferson County, Alabama, who were licensed to drive or who possessed nondriver identification cards issued through the Alabama Department of Public Safety, and they recruited from UAB eye clinics. The Hebrew Rehabilitation Center for the Aged (HRCA) in Boston, Massachusetts, recruited from congregate and senior housing sites, senior centers, and a registry of volunteers for aging research at the Harvard Cooperative Program on Aging. Indiana University recruited clients of the Community Centers of Indianapolis and through local churches and senior organizations. Johns Hopkins University recruited from senior centers, churches, senior housing, and senior organizations in the Baltimore, Maryland, metropolitan area and in Cumberland, Maryland. Pennsylvania State University recruited from the enrollment files of a state-funded pharmaceutical assistance program for low-income elders, called PACE. And Wayne State University recruited from community organizations, churches, and senior housing in metropolitan Detroit, as well as from state of Michigan driver registration lists. The study design also included a no-contact control group.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Standardized missing values.
- Checked for undocumented or out-of-range codes.
