目标：常识性疾病信念很重要，因为它们影响人们预防和治疗疾病的行动。本研究(1)询问了年轻人和老年人阿尔茨海默病（AD）的疾病表征，(2)操纵了人们对AD可预防性的看法，以确定数据中的因果关系。方法：在研究1中，比较年轻（18-38岁，n = 82）和老年（58-89岁，n = 57）成年人对AD病因和预防方法的看法。在研究2中，年轻人被随机分配阅读AD可以预防或不能预防的信息。结果：与年轻人相比，老年人认为自己患AD的风险较小，t(137) = 3.03, p = 0.003, d = 0.52，更有可能相信AD是可以预防的，t(137) = 5.01, p < 0.001, d = 0.87，更有可能报告从事预防AD的行为，chi(2) (1,139) = 19.01, p < 0.001, r = 0.37。在研究2中，操纵信念导致那些被告知阿尔茨海默病是可以预防的人认为自己的风险更低，报告了更多的预防行为，并认为患有这种疾病的人对自己的命运负有更多的责任。结论：这些发现强调了疾病表现与行为报告的关联，并显示了信念与我们目前对AD的了解之间的脱节。
Objectives: Common-sense illness beliefs are important because they influence actions that people take to prevent and treat disease. This research (1) asked younger and older adults about their illness representations of Alzheimer's disease (AD) and (2) manipulated beliefs about AD preventability to determine causal relationships in the data.Method: In Study 1, the beliefs of younger (age 18-38; n = 82) and older (age 58-89; n = 57) adults about the causes of and ways to prevent AD were compared. In Study 2, younger adults were randomly assigned to read information stating either that AD can be prevented or not.Results: Compared to younger adults, older adults saw themselves as less at risk, t(137) = 3.03, p = 0.003, d = 0.52, were more likely to believe that AD is preventable, t(137) = 5.01, p < 0.001, d = 0.87 and were more likely to report engaging in behaviors to prevent AD, chi(2) (1, 139) = 19.01, p < 0.001, r = 0.37. Manipulating beliefs in Study 2 caused those told that AD was preventable to see themselves as less at risk, report more prevention behaviors, and hold those with the disease more responsible for their fate.Conclusion: These findings highlight the association of illness representations with reports of behavior and show a disconnect between beliefs and what we currently know about AD.
