Understanding health beliefs and how they influence willingness will enable the development of targeted curricula that maximize public engagement in Alzheimer's disease (AD) risk reduction behaviors.
Literature on behavioral theory and community input was used to develop and validate a health beliefs survey about AD risk reduction among 428 community-dwelling adults. Principal component analysis was performed to assess internal consistency. Linear regression was performed to identify key predictors of Willingness to engage in AD risk reduction behaviors.
The measure as well as the individual scales (Benefits, Barriers, Severity, Susceptibility and Social Norm) were found to be internally consistent. Overall, as Benefits and Barriers scores increased, Willingness scores also increased. Those without prior AD experience or family history had lower willingness scores. Finally, we observed an interaction between age and norms, suggesting that social factors related to AD prevention may differentially affect people of different ages.
The Alzheimer Prevention Beliefs Measure provides assessment of several health belief factors related to AD prevention. Age, Family History, Logistical Barriers and total Benefits are significant determinants of willingness to engage in AD risk reduction behaviors, such as seeing a doctor or making a lifestyle change.
了解健康信念及其如何影响意愿，将有助于制定有针对性的课程，最大限度地提高公众参与阿尔茨海默病（AD）风险降低行为的意愿。
利用行为理论文献和社区投入，为 428 名居住在社区的成年人开发并验证了一项关于 AD 风险降低的健康信念调查。采用主成分分析评估内部一致性。进行线性回归分析以确定参与 AD 风险降低行为的意愿的关键预测因素。
该测量方法以及各个量表（益处、障碍、严重程度、易感性和社会规范）都具有内部一致性。总体而言，随着益处和障碍得分的增加，意愿得分也随之增加。那些没有 AD 既往病史或家族史的人意愿得分较低。最后，我们观察到年龄和规范之间存在交互作用，表明与 AD 预防相关的社会因素可能会对不同年龄的人产生不同的影响。
《阿尔茨海默病预防信念量表》提供了与 AD 预防相关的几个健康信念因素的评估。年龄、家族史、实际障碍和总益处是参与 AD 风险降低行为（如看医生或改变生活方式）的意愿的重要决定因素。
