项目摘要

DESCRIPTION (provided by applicant): Older adults face a range of medical decisions. Effective decision-making requires access to reliable information and the coordination of cognitive processes such as attention, memory, and reasoning. Age-related declines in health-related decision-making processes have been observed and attributed to insufficient familiarity with health-related information and declines in cognition. The Internet has the potential to meet older adults' needs for a diverse range of health information. Yet, age-related declines in cognitive abilities and a lack of age-appropriate training make it challenging for older adults to take full advantage of the technology. Thus, there is a dire need for interventions that can 1) improve older adults' ability to obtain and evaluate online health information, and 2) strengthen cognitive processes that are key to daily health-related behaviors (e.g., information seeking for informed health decision-making). To address this need, the proposed study will develop and evaluate a 3-month intervention designed to teach older adults how to obtain and evaluate online health information and improve cognitive function. This intervention represents a theoretically motivated extension of our team's pilot research on computer training to teach older adults how to find reliable health information on the Internet. The proposed intervention incorporates three key principles: 1) collaborative learning, 2) a range of activities that depend on a combination of cognitive processes, and 3) real world problem solving. The intervention will be evaluated via a randomized controlled trial with a 2 x 2 x 2 mixed factorial design, with degree of engagement in a collaborative learning program (high engagement; low engagement) and cognitive training (present; absent) as the between-subjects variables and time of measurement (pre; post;) as the within-subjects variable. The proposed study has the following specific aims: Aim 1: To develop training curricula (problem sets and activities that are relevant to older adults' everyday life decisions regarding health) collaboratively with and among older adults to promote older adults' ability to obtain and evaluate online health information. Aim 2: To determine if the combination of high engagement in collaborative learning plus cognitive training yields larger or broader improvements in older adults' ability to obtain and evaluate online health information, cognitive performance (attention, working memory, reasoning, retrospective memory and prospective memory), and health decision-making from pre- to post-intervention than either alone. Aim 3: To determine if there are independent effects of the degree of engagement (high engagement; low engagement) in a collaborative learning program and/or cognitive training (presence; absence) on these outcomes from pre- to post-intervention.

描述（由申请人提供）：老年人面临一系列医疗决定。有效的决策需要获得可靠的信息和协调的认知过程，如注意力，记忆和推理。已经观察到与健康有关的决策过程中与性别有关的下降，并将其归因于对健康相关信息的不熟悉和认知能力的下降。互联网有潜力满足老年人对各种健康信息的需求。然而，与年龄相关的认知能力下降和缺乏与年龄相适应的培训，使老年人充分利用这项技术具有挑战性。因此，迫切需要能够1）提高老年人获得和评估在线健康信息的能力，以及2）加强对日常健康相关行为至关重要的认知过程（例如，为知情的健康决策寻求信息）。为了满足这一需求，拟议的研究将开发和评估一项为期3个月的干预措施，旨在教老年人如何获取和评估在线健康信息，并改善认知功能。这种干预是我们团队关于计算机培训的试点研究的理论动机延伸，该研究旨在教老年人如何在互联网上找到可靠的健康信息。拟议的干预措施包括三个关键原则：1）协作学习，2）一系列依赖于认知过程组合的活动，3）解决真实的世界问题。将通过一项随机对照试验采用2 x 2 x 2混合析因设计评价干预措施，其中协作学习计划中的参与程度（高参与度;低参与度）和认知培训（存在;不存在）作为受试者间变量，测量时间（前;后;）作为受试者内变量。拟议的研究有以下具体目标：目标1：与老年人合作并在老年人之间开发培训课程（与老年人日常生活中有关健康的决定有关的问题集和活动），以提高老年人获取和评估在线健康信息的能力。目标2：确定协作学习的高参与度与认知训练的结合是否能更大或更广泛地改善老年人获取和评估在线健康的能力信息，认知表现（注意力，工作记忆，推理，回顾性记忆和前瞻性记忆）和健康决策从干预前到干预后比单独。目标三：确定在协作学习计划和/或认知训练（存在;不存在）中，参与程度（高参与度;低参与度）是否对干预前后的这些结果产生独立影响。
