Investigating the relation between social isolation and cognitive function will allow us to identify components to incorporate into cognitive interventions.
Data were collected from 267 Appalachian older adults (M = 78.5, range 70-94 years). Overall cognitive functioning and specific cognitive domains were assessed from data of a self-assembled neuropsychological battery of frequently used tasks. Social isolation, social disconnectedness, and perceived isolation were measured from the Lubben Social Network scale-6.
Results indicated a significant positive association between all predictor variables (e.g., social isolation, social disconnectedness, and perceived isolation) and outcome variables (e.g., overall cognitive function, memory, executive functioning, attention, and language abilities). Perceived isolation accounted for nearly double the amount of variance in overall cognitive functioning than social disconnectedness (10.2% vs. 5.7%).
Findings suggest that social isolation is associated with poorer overall cognitive functioning and this remains true across varied cognitive domains.
研究社会隔离与认知功能之间的关系，将有助于我们确定可纳入认知干预措施的组成部分。
收集了267名阿巴拉契亚老年人（年龄中位数为78.5岁，范围在70至94岁之间）的数据。通过一个自行组装的、包含常用任务的神经心理测验组合数据，评估总体认知功能和特定认知领域。使用鲁本社交网络量表 - 6来测量社会隔离、社交脱节和感知到的隔离情况。
结果表明，所有预测变量（如社会隔离、社交脱节和感知到的隔离）与结果变量（如总体认知功能、记忆、执行功能、注意力和语言能力）之间存在显著的正相关。在总体认知功能方面，感知到的隔离所解释的方差量几乎是社交脱节的两倍（10.2% 对 5.7%）。
研究结果表明，社会隔离与较差的总体认知功能相关，并且在不同的认知领域都是如此。
