Alzheimer's disease (AD) is associated with considerable caregiver and social burden. It is important to examine ways to minimize the negative effects of AD. Health care advocates (HCAs) may be one means of limiting the aversive effects of AD.
Participants completed a short survey that assessed their perceptions of the impact of comorbid AD on health status and their likelihood of hiring an HCA to assist in managing it. A mediational model was proposed: cognitive status (AD vs cognitively healthy) was the independent variable, perception of severity was the mediator, and the probability of hiring an HCA was the dependent variable.
The results indicated that the relationship between cognitive status and probability of hiring an HCA was fully mediated by perceptions of severity.
This study demonstrated that participants appreciated the impact of AD on health status, and this translated into a greater probability of hiring an HCA.
阿尔茨海默病（AD）与相当大的照顾者和社会负担有关。重要的是要研究如何将 AD 的负面影响降到最低。医疗保健倡导者（HCAs）可能是限制 AD 不良影响的一种手段。
参与者完成了一项简短的调查，评估了他们对 AD 共病对健康状况的影响的看法，以及他们聘请 HCAs 协助管理的可能性。提出了一个中介模型：认知状态（AD 与认知健康）是自变量，感知严重程度是中介变量，聘请 HCAs 的可能性是因变量。
结果表明，认知状态与聘请 HCAs 的可能性之间的关系完全由严重程度的感知所介导。
本研究表明，参与者认识到 AD 对健康状况的影响，这转化为聘请 HCAs 的可能性更大。
