Research on Constructing of Uncertainty Belief Behavior Theory

Uncertainty is an inherent property of things and has become a norm in contemporary society. In this context, the occurrence of health behaviors is inevitably closely linked to uncertainty. However, existing health behavior theories have yet to incorporate uncertainty into their framework. This paper addresses a gap in the existing literature by incorporating uncertainty into the cognitive health behavior framework, thereby developing the Uncertainty Belief Behavior Theory. By combining uncertainty with cognitive beliefs, this theory explores the social behavioral mechanisms behind decision-making in uncertain situations. The paper first reviews and reflects on the existing literature, deepening the understanding of the attributes and phenomena of uncertainty. It argues for the rationale and feasibility of integrating uncertainty into the cognitive health behavior theory framework. Based on this foundation, real-world data were used to empirically test the proposed theory. The results of multiple linear regression analysis show that, when accounting for uncertainty, there is a significant positive association between risk perception and hypertension prevention behavior (β = 0.397, p < 0.001). Further analysis reveals that the "confusion" caused by uncertainty plays a significant mediating role between risk perception and hypertension prevention behavior (β = -0.100, p < 0.05), accounting for 25.2% of the total effect, indicating a partial mediation effect. Finally, the paper discusses the understanding and application of the Uncertainty Belief Behavior Theory. By introducing the concept of uncertainty belief, the theory provides a better explanation for individual health behaviors in complex environments and offers a theoretical foundation for designing more effective intervention strategies. This study focuses solely on cognitive health behavior theory. Future research could consider integrating uncertainty into other theoretical frameworks, thus broadening the scope of health behavior research and better addressing the increasingly complex public health challenges. 不确定性是事物的固有属性，且已成为当代社会的常态。在此背景下，健康行为的发生必然与不确定性产生紧密联系。然而，现有的健康行为理论尚未将不确定性纳入其框架。填补了文献空白，本文将不确定性融入现有的认知健康行为理论框架，构建了不确定信念行为理论。该理论通过将不确定性与认知信念结合，探讨了在不确定情境下人们决策的社会行为机制。文章首先对现有文献进行了梳理与思考，深入理解了事物的不确定性属性和现象，论证了不确定性融入认知健康行为理论体系的合理性和可行性。在此基础上，应用真实世界数据对所构架的理论进行了验证。多元线性回归分析结果显示，在考虑不确定性的情况下，危险性感知与高血压预防行为之间呈现显著的正向关联（β = 0.397, p < 0.001）。进一步分析显示，不确定性所引发的“迷茫感”在危险性感知与高血压预防行为之间起到了显著的中介作用（β = -0.100, p < 0.05），其效应值占总效应的25.2%，表明具有部分中介作用。最后，文章对不确定信念行为理论的理解和应用进行了讨论。不确定信念行为理论能够更好地解释个体在复杂环境下的健康行为，并为制定更加有效的干预策略提供理论基础。本文仅涉及认知健康行为理论，未来的研究可考虑将不确定性融入其他理论框架，推动健康行为研究向更广阔的方向发展，从而更好地应对日益复杂的公共健康挑战。
