A sense of purpose in life is associated with healthier cognitive outcomes, including lower risk of Alzheimer's Disease (ad). The present research examines whether purpose is also associated with beliefs and knowledge of ad.
A random subsample (N = 1,187) of community-dwelling participants from the Health and Retirement Study completed a module on self-reported beliefs and knowledge of ad.
Purpose in life was associated with lower perceived threat of ad and greater belief that modifiable factors (e.g., physical activity) decrease risk. Associations were not moderated by experience with ad or depressive symptoms. Purpose was unrelated to beliefs that genetics or stress increase risk or knowledge of ad.
Individuals with a sense of purpose are less concerned about risk of developing ad and believe modifiable factors reduce risk. These beliefs may support engagement in behaviors that reduce risk and be one psychological pathway through which purpose protects against ad.
人生意义感与更健康的认知结果相关，包括降低阿尔茨海默病（ad）的风险。本研究探讨了人生意义感是否也与 ad 的信念和知识相关。
健康与退休研究中的社区居住参与者的随机子样本（N=1187）完成了一个关于自我报告的 ad 信念和知识的模块。
人生意义感与较低的 ad 感知威胁以及更大的信念相关，即可改变的因素（如身体活动）降低风险。关联不受 ad 经历或抑郁症状的调节。目的与遗传或压力增加风险或 ad 知识的信念无关。
有人生意义感的个体对患 ad 的风险不太担心，并相信可改变的因素会降低风险。这些信念可能支持人们采取降低风险的行为，并且是目的感预防 ad 的一种心理途径。
