背景结直肠癌（CRC）的死亡率很高。了解早期检测实践（如筛查）的社会，心理和认知预测因素可能有助于改善CRC结果。本研究在全国代表性人群样本中调查了CRC的知识以及知识、对癌症的态度和从事CRC早期发现行为的意图之间的关系。在英国16 ~ 74岁成年人样本中进行了一项基于访谈的调查（n = 1637），评估结直肠癌相关知识、态度和意向。知识水平非常低; 58%（n = 995）的受访者无法列出任何结直肠癌风险因素，24%（n = 393）的受访者无法识别癌症的任何警告信号。男性（chi（2）[2] = 52.8，P < 0.0001）、年轻受访者（chi（2）[10] = 79.9，P <0.0001）和受教育程度较低的受访者（chi（2）[4] = 73.9，P < 0.0001）的知识水平较低。对癌症的态度更为消极;女性（chi（2）[2] = 7.4，P = 0.025），年轻参与者（chi（2）[10] = 22.4，P = 0.013）和受教育程度较低的人（chi（2）[4] = 75.0，P < 0.0001）。低知识与消极态度相关（P < 0.0001），这两个因素与参与结直肠癌筛查的意愿较低相关（P < 0.0001）。多因素分析表明，态度在知识对筛查意向的影响中起部分中介作用。增加知识可能会减少公众对癌症的负面看法，这可能会对参与筛查的意愿产生积极影响。(C)2003年美国健康基金会和爱思唯尔科学（美国）。All rights reserved.
Background. Colorectal cancer (CRC) mortality is high. Understanding the social, psychological, and cognitive predictors of early detection practices such as screening may help improve CRC outcomes. This study examined knowledge of CRC and the relationship between knowledge, attitudes to cancer, and intentions to engage in early detection behaviors for CRC in a national representative population sample.Method. An interview-based survey was carried out in a British population sample of adults ages 16 to 74 years (n = 1637), assessing knowledge, attitudes, and intention with regard to colorectal cancer.Results. Knowledge levels were very low; 58% (n = 995) of respondents could not list any colorectal cancer risk factors and 24% (n 393) were unable to identify any warning signs for cancer. Knowledge was lower among men (chi(2)[2] = 52.8, P < 0.0001), younger respondents (chi(2)[10] = 79.9, P < .0001), and those with less education (chi(2)[4] = 73.9, P < 0.0001). Attitudes to cancer were more negative ;among women (chi(2) [2] = 7.4, P = 0.025), younger participants (chi(2)[10] = 22.4, P = 0.013), and those with less education (chi(2) [4] = 75.0, P < 0.0001). Low knowledge was associated with negative attitudes (P < 0.0001) and both factors were associated with lower intentions to participate in colorectal cancer screening (P < 0.0001). Multivariate analysis indicated that attitudes partially mediated the effect of knowledge on screening intentions.Conclusion. Increasing knowledge may reduce negative public perceptions of cancer which may impact positively on intentions to participate in screening.
