更高的亲社会意图与老年人更好的认知健康有关. 这包括语言记忆和执行功能下降的速度较慢,以及痴呆症风险降低,这表明志愿服务之外的好处.
科学领域:
- 老年学和认知衰老研究研究
- 社会心理学和健康行为
背景情况:
- 亲社会性,包括积极的对待他人意图和行为,是与老年人改善健康结果相关的可修改因素.
- 以前的研究主要集中在志愿服务等特定的亲社会行为上,这在理解更广泛的亲社会意图对认知健康的影响方面存在差距.
研究的目的:
- 在老年人中调查亲社会意图与随着时间的推移保持认知健康之间的关联.
- 确定亲社会意图是否预测执行功能和口头记忆的变化,以及痴呆的风险.
主要方法:
- 利用了来自50岁以上的7,844名成年人的英语长度老龄研究数据.
- 使用9项尺度衡量利他主义和集体主义来评估亲社会意图.
- 通过执行功能和口头记忆任务测量认知健康,并在11年内诊断痴呆症,使用混合效应和Cox比例危险模型进行分析.
主要成果:
- 更高的亲社会意图与更好的认知健康维护有显著的关联,即使在控制共变量之后.
- 具有高亲社会意图的个体表现出语言记忆的下降速度较慢的24%,执行功能下降速度较慢的55%.
- 更高的亲社会意图与发展痴呆症的风险降低了35%.
结论:
- 除了正式的志愿者之外,亲社会性在保持老年人认知健康方面发挥着至关重要的作用.
- 这些发现强调了亲社会意图作为旨在促进健康认知衰老的干预措施的潜在目标.
