Primary Outcome Measures:
  • Changes in Cognitive Abilities of Memory From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    Memory outcome was computed as the summation of Rey Auditory-Verbal Learning Test (AVLT), the Hopkins Verbal Learning Test (HVLT), and the Rivermead Behavioral Paragraph Recall test immediate recall. The possible range of the memory outcome is 0 to 132. Higher values represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.

  • Changes in Cognitive Abilities of Reasoning From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    Reasoning outcome was computed as the summation of total correct for Letter Series, Letter Sets, and Word Series. The possible range of the reasoning outcome is 0 to 75. Higher values represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.

  • Changes in Cognitive Abilities of Speed of Processing From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    Speed of processing outcome was computed as the summation of three Useful Field of View tasks requiring identification and localization of information, with 75% accuracy, under varying levels of cognitive demand. For the analysis, the reversed score was used and the possible range of the reversed speed of processing outcome is 0 to 1500. Higher values for the reversed scores represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.

  • Changes in Instrumental Activities of Daily Living (IADL) Difficulty From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    The self-reported measure of everyday IADL function was the summation of the IADL difficulty sub-scores from the Minimum Dataset - Home Care (MDS-HC) which assesses performance in the past 7 days on 19 daily tasks spanning meal preparation, housework, finances, health care, telephone, shopping, travel, and need for assistance in dressing, personal hygiene, and bathing. For the analysis, the reversed score was used and the possible range of the reversed everyday IADL function outcome is 0 to 38. Higher values for the reversed scores represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.

  • Changes in Everyday Problem Solving From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    Everyday Problem Solving was computed as the summation of the Everyday Problems Test (EPT) and Observed Tasks of Daily Living (OTDL). The possible range of the everyday problem solving outcome is 0 to 56. Higher values represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.

  • Changes in Everyday Speed of Processing From Baseline to Year 10 [ Time Frame: Up to 10 years ] [ Designated as safety issue: No ]
    Everyday Speed of processing was computed as the summation of Complex Reaction Time (CRT) and Timed IADL (TIADL). For the analysis, the reversed score was used and the possible range of the reversed everyday speed of processing outcome is -3 to 100. Higher values for the reversed scores represent a better outcome. Changes in outcome were computed as "10 year minus baseline" and the negative values indicate the decline from baseline.


Secondary Outcome Measures:
  • Changes in Health-related Quality of Life (HRQol), Driving Function, Health Service Use [ Time Frame: 10th Year ] [ Designated as safety issue: No ]
    To determine if the cognitive interventions have beneficial effects on the distal outcomes of driving safety, personal care activities of daily living, health service utilization, and mortality.

  • Examine Health, Genetic and Cognitive Moderators [ Time Frame: 10th Year ] [ Designated as safety issue: No ]
    To examine heath, genetic, and cognitive moderators (including cardiovascular disease,diabetes, depression, Apolipoprotein E (APOE) genotype, and low cognition and engagement) in individual response to training.

  • Estimate the Effects of ACTIVE Training to General Population [ Time Frame: 10th Year ] [ Designated as safety issue: No ]
    To estimate and project the effects of ACTIVE training to the general population of older adults by linking the measures and outcomes of ACTIVE to the Health and Retirement Study(and its subsidiary studies), a population-based, nationally-representative cohort.

Arms Assigned Interventions
Active Comparator: Memory Training
Memory training focused on verbal episodic memory. Participants were taught mnemonic strategies for remembering lists and sequences of items, text material, and main ideas and details of stories and other text-based information.
Behavioral: Cognitive Training
Memory, Reasoning, or Speed of Processing cognitive training interventions
Active Comparator: Reasoning Training
Reasoning training focused on the ability to solve problems that follow a serial pattern. Participants were taught strategies to identify the pattern or sequence required to solve a problem.
Behavioral: Cognitive Training
Memory, Reasoning, or Speed of Processing cognitive training interventions
Active Comparator: Speed of Processing Training
Speed of processing training focused on visual search and the ability to identify and locate visual information quickly in a divided attention format. Participants practiced increasingly complex speeded tasks on a computer.
