低计算能力可能会扭曲患者对癌症信息的看法。本文使用来自2007年健康信息全国趋势调查(HINTS-3)的3052名受访者的结果，研究了自我报告的知觉算术测量与癌症知识、信念和情感之间的关系。卡方检验被用来确定高和低计算能力组之间的反应差异，使用三种感知计算能力的衡量标准。运用多因素Logistic回归模型分析三种知觉计算方法与癌症信息过载、癌症宿命论、癌症预防知识、癌症忧虑之间的关系。对医学统计数字感到不适的受访者更有可能报告信息过载，对癌症表现出宿命论态度，缺乏癌症预防知识，并表示他们更频繁地担心癌症。在控制了社会人口统计特征后，这种感知算术能力的测量仍然与信息过载、宿命论、较低的预防知识和担忧显著相关。其他衡量感知算术能力的指标，即对健康统计数据的理解和使用，与癌症认知无关。我们的发现表明，感知算术能力低的人与感知算术能力高的人在癌症和癌症预防方面的认知大体不同。通过提高我们对感知到的计算能力如何影响患者对癌症的看法的理解，卫生服务提供者可以改进教育战略和有针对性的卫生信息。
Low numeracy may skew patient perceptions of information about cancer. This paper examines the relationship between self-reported measures of perceived numeracy and cancer knowledge, beliefs, and affect, using results from 3,052 respondents to the 2007 Health Information National Trends Survey (HINTS-3). Chi-squared tests were used to identify differences in responses between high- and low-numeracy groups using three measures of perceived numeracy. Multivariable logistic regression models were used to evaluate the association between the three perceived numeracy measures and cancer information overload, cancer fatalism, cancer prevention knowledge, and cancer worry. Respondents with low perceived numeracy as expressed by discomfort with medical statistics were more likely to report information overload, to display fatalistic attitudes towards cancer, to lack knowledge about cancer prevention, and to indicate that they worried about cancer more frequently. After controlling for sociodemographic characteristics, this measure of perceived numeracy remained significantly associated with information overload, fatalism, lower prevention knowledge, and worry. The other measures of perceived numeracy, which measured understanding and use of health statistics, were not associated with cancer perceptions. Our findings suggest that individuals with low perceived numeracy broadly differ from individuals with high perceived numeracy in their perceptions of cancer and cancer prevention. By improving our understanding of how perceived numeracy affects patient perceptions of cancer, health providers can improve educational strategies and targeted health messaging.
