在这项研究中，我们应用“模糊性”的概念，在决策理论文献中开发的，对癌症预防建议的不确定性的潜在心理后果的分析。我们使用健康信息国家趋势调查（HINTS）2003年数据来研究癌症预防建议的感知模糊性如何与已知影响癌症保护行为的其他三个认知变量相关：感知的癌症可预防性、感知的癌症风险和与癌症相关的担忧。使用逻辑回归分析，我们测试了几个预测来自文献综述的模糊性的看法对决策，认知和情绪的影响。我们发现，感知的模糊性与感知的癌症可预防性有很强的负相关关系，与“模糊厌恶”一致-对模糊性的解释的悲观偏见。对癌症的担忧调节了这种关系;随着担忧程度的增加，模糊厌恶感增加。同时，认知模糊与癌症风险和癌症担忧均呈正相关。此外，知觉风险在知觉模糊与焦虑之间起部分中介作用。这些发现表明，癌症预防建议的模糊性可能对其他健康认知产生广泛而重要的影响。我们讨论了这些研究结果对健康传播工作的伦理影响，并提出了一个初步的因果关系模型，以指导未来的研究。
In this study, we apply the concept of "ambiguity," as developed in the decision theory literature, to an analysis of potential psychological consequences of uncertainty about cancer prevention recommendations. We used Health Information National Trends Survey (HINTS) 2003 data to examine how perceived ambiguity about cancer prevention recommendations relates to three other cognitive variables known to influence cancer-protective behavior: perceived cancer preventability, perceived cancer risk, and cancer-related worry. Using logistic regression analyses, we tested several predictions derived from a review of literature on the effects of ambiguity perceptions on decision making, cognitions, and emotions. We found perceived ambiguity to have a strong negative relationship with perceived cancer preventability, consistent with "ambiguity aversion"-a pessimistic bias in the interpretation of ambiguity. Cancer worry moderated this relationship; ambiguity aversion increased with higher levels of worry. At the same time, perceived ambiguity was positively related to both perceived cancer risk and cancer worry. Furthermore, perceived risk partially mediated the relationship between perceived ambiguity and worry. These findings suggest that perceived ambiguity about cancer prevention recommendations may have broad and important effects on other health cognitions. We discuss ethical implications of these findings for health communication efforts, and propose a tentative causal model to guide future research.
