本研究探讨了在急性家畜流行病的背景下，健康行为和风险认知之间的关系。参与者在一个纵向的基于网络的调查（N = 195）被要求报告他们的肉类消费和他们的感知风险有关的牛海绵状脑病（BSE）和其他相关的牲畜疾病。在两个测量点（T1和T2）的横断面分析显示，预防性营养水平低（高肉类消费）的参与者比报告预防性行为水平较高（低肉类消费）的参与者更容易患疯牛病相关疾病，这表明相对准确性。这些结果表明，人们认识到他们的行为是危险的。更重要的是，从变化的角度来看，感知风险也显示出适应性的准确性：从T1到T2的预防性营养增加与T1和T2之间感知风险的降低显著相关。可能的基础和影响的风险认知的自适应准确性进行了讨论。
This study examined the relation between health behavior and risk perceptions in the context of an acute livestock epidemic. Participants in a longitudinal web-based survey (N = 195) were asked to report their meat consumption and their perceived risk in relation to bovine spongiform encephalopathy (BSE) and other related livestock diseases. Cross-sectional analyses at both measurement points (T1 and T2) showed that participants with low levels of preventive nutrition (high meat consumption) felt more at risk for BSE-related diseases than those reporting comparable higher levels of preventive behavior (low meat consumption), indicating relative accuracy. These results suggest that people recognize when their behavior is risky. More importantly, perceived risk also showed adaptive accuracy from a change perspective: increases in preventive nutrition from T1 to T2 were significantly associated with decreases in perceived risk between T1 and T2. Possible foundations and implications of an adaptive accuracy of risk perceptions are discussed.
