简要总结
Evidence shows the positive effects of Brain Health & Wellness classes in younger individuals. The proposed study investigates the usefulness of these classes in older Veterans aged 50-85. We hope to show that such classes can lead to improvements in both thinking skills as well as stress levels.
详细描述
The expansion of the aging Veteran population, in addition to the frequent presence of comorbidities (e.g., PTSD and TBI) that exacerbate age-associated cognitive and health declines, has generated substantial interest in interventions that promote brain health in older Veterans. A growing body of evidence shows the positive effects of Brain Health & Wellness classes on brain health in younger and middle-aged adults, thus training might be able to enhance brain health in older Veterans and offset age-related declines. Such training holds particular promise in enhancing areas of cognition that are especially susceptible to aging processes (e.g. attention and executive control), potentially through multiple mechanistic pathways. It is in many respects a cognitive exercise and may strengthen neural networks involved in such processes. Additionally, there is evidence for further facilitating brain health in other ways related to, for instance, altering the stress response. Currently, there is little information regarding the potential brain health benefits in older adults. As a first step to understanding these potential beneficial effects in Veterans, the aim of the proposed pilot study is to evaluate the acceptability, feasibility and potential efficacy of two Brain Health & Wellness classes in healthy older Veterans through a randomized, controlled trial.

结局指标
主要结局
State-Trait Anxiety Inventory (STAI) Change Score
时间窗: Baseline (within two weeks pre-intervention) and Outcome at 2 months (within 2 weeks post-intervention)
Participants' scores on the State-Trait Anxiety Inventory (STAI) were collected within 2 weeks before the intervention and again within 2 weeks after the intervention. This outcome measure represents the change in score in State-Trait Anxiety Inventory: pre-intervention score minus post-intervention score. The maximum STAI score is 80, and the minimum score is 20. Higher scores on the STAI indicate more anxiety symptoms, so worse outcome. However, since we are analyzing a change in the STAI score of pre- minus post-intervention, a larger change score for a particular arm indicates a greater degree of improvement.
Geriatric Depression Scale Change Score
时间窗: Baseline (within two weeks pre-intervention) and Outcome at 2 months (within 2 weeks post-intervention)
Participants' scores on the Geriatric Depression Scale were collected within 2 weeks before the intervention and again within 2 weeks after the intervention. This outcome measure represents the change in score in Geriatric Depression Scale: pre-intervention score minus post-intervention score. The maximum Geriatric Depression Scale score is 30, and the minimum score is 0. Higher scores on the Geriatric Depression Scale indicate more depressive symptoms, so worse outcome. However, since we are analyzing a change in the Geriatric Depression Scale score of pre- minus post-intervention, a larger change score for a particular arm indicates a greater degree of improvement.
