Introduction: Several interventions have been developed to enhance social connectedness among older adults. However, little research has demonstrated their performance in a distancing environment. Exergames are not only beneficial adults' physical and cognitive health, but they also allow players interact with each other at distance, which can reduce loneliness increase connection. The aim of this pilot study was investigate perceptions two commercially available exergames. Methods: Twenty...

Driving is important for older adults' health and well-being, yet little research has examined interventions to maintain driving mobility. As fluid cognitive abilities are strongly linked driving, targeted training may impact mobility longitudinally. This study assessed the effects of three different programs (reasoning, speed processing, memory) on cessation in adults across 10 years (n = 2,390). Cox regression analyses evaluated each program relative a no-contact control group with...

Physical activity (PA) is believed to preserve cognitive function in older adulthood, though little known about these relationships within the context of daily life. The present microlongitudinal pilot study explored within- and between-person between PA also examined within-person effect sizes a sample community-dwelling adults. Fifty-one healthy participants (mean age = 70.1 years) wore an accelerometer completed assessment battery for five days. There were no significant associations task...

There are positive relationships between physical and cognitive function in older adulthood; however, the strength of these inconsistent across studies. Although novel statistical tools provide flexibility to explore age-related differences relationship magnitude, such methods have not been implemented gerontological research. This study applied examine variations magnitude cognition healthy adults (N = 2,783). Time-varying effects modeling (TVEM) is an extension regression that models...

Objective: Physical functioning is closely associated with cognition. The current study assessed the impact of three cognitive training programs on objective measures physical across 5 years. Method: Older adults randomized to a processing speed ( n = 702), reasoning 694), or memory 703) intervention were compared those no-contact control condition 698). Intention-to-treat (ITT) and treatment-received/dosage (time-varying number sessions) analyses conducted. Results: There no transfer...

Financial incentives can increase physical activity (PA), but differences in the immediacy of reward delivery and individual delay discount rates (i.e., higher values associated with less tolerance for delayed rewards) may explain differential responding. The current study tested whether rate moderated relative effectiveness immediate financial rewards on increasing daily PA. Inactive, overweight adults (ages 18–60, N = 96) were randomized to receive either smaller, goal-contingent or...

Potent lifestyle interventions to increase moderate-to-vigorous physical activity are urgently needed for population-level chronic disease prevention. This trial tested the independent and joint effects of a mobile health system automating adaptive goal setting immediate financial reinforcement increasing daily walking among insufficiently active adults.

Although the health benefits of behavioral interventions for older adults are well studied, research focused on intervention acceptability in adult populations is less established and needed. This mixed methods study investigated adults' perceptions training interventions.

The objective of this longitudinal study was to examine time-varying correlations between multiple indexes physical function and driving mobility in older adults across 5 years. participants were drivers aged 65 91 ( M = 73.6 ± 5.78) who randomly assigned the no-contact control arm Advanced Cognitive Training for Independent Vital Elderly Study N 598). outcomes self-reported space, exposure, frequency, weekly mileage assessed at baseline first, second, third, fifth follow-up visits. Physical...

Abstract Objectives Poor physical function is associated with negative health and cognitive outcomes. Although nine studies demonstrated that training reduces age-related declines in function, only one study has examined the effects beyond immediate posttest changes. The first aim of this was to assess impact three programs on measures across 10 years second examine whether baseline self-efficacy or depressive symptoms moderated effects. Method Using data from Advanced Cognitive Training for...

Individual- and environmental-level factors may explain differential trajectories in lifespace mobility older adults. The current study tested whether driving status was associated with lifespace, change varied by status, residential context moderated the relationship between lifespace. Participants were adults ages 65 to 94 (mean = 73.6 + 5.9) enrolled Advanced Cognitive Training for Independent Vital Elderly Study (N 2,792). Lifespace assessed at baseline first, second, third, fifth annual...

Abstract Background Ecological models suggest that interventions targeting specific behaviors are most effective when supported by the environment. This study prospectively examined interactions between neighborhood walkability and an mHealth intervention in a large-scale, adequately powered trial to increase moderate-to-vigorous physical activity (MVPA). Methods Healthy, insufficiently active adults (N = 512) were recruited purposefully from census block groups ranked on (high/low)...

Delay discounting is the depreciation in a reward's perceived value as function of time until receipt. Monetary incentive programs that provide rewards contingent on meeting daily physical activity (PA) goals may change participants' delay preferences.

ABSTRACT: Rockfall along mountainous roadways poses a hazard to transportation infrastructure, commercial traffic, and the public. Lidar scanning photogrammetry are powerful tools create high-resolution point cloud models of rock slopes quantify change, facilitating rockfall volume estimation. The empirical magnitude-cumulative frequency (MCF) distribution defines number rockfalls various sizes that occur for certain study area over given period time. time required MCF curve fit parameters...

As the population ages, it is essential that professionals across disciplines have experience and competence working with older adults. Though experiential learning opportunities been extensively documented as a tool to accomplish this goal, student engagement in gerontology research has not examined detail. This participatory case study highlights perspectives of undergraduate researchers involved hands-on pilot explored connections between cognitive, physical, everyday function midlife...

This study explores whether living situation modifies longitudinal associations between depressive symptoms and changes in cognitive status across ten years generally healthy, community-dwelling older adults. Participants ( N = 687, M age 73.92 years) from the no-contact control condition of a multisite completed Mini-Mental State Examination, Center for Epidemiological Studies Depression scale, self-reported situation. Multilevel models revealed that adults alone, having clinically...
