感知风险是健康行为研究的核心理论建构。参与者对感知风险项目（DKPR）的“不知道”反应通常被排除在分析之外。然而，提供这种回答的人可能有独特的癌症信息需求。我们探讨了DKPR反应可能是由于癌症知识缺陷或知识缺陷的行为、技能和态度前因（分别是信息寻求、计算能力和自我效能）。分析了2005年健康信息全国趋势调查（提示，N=1,789）、一项基于美国人口的调查和一项城市、少数民族、初级保健诊所调查（N=590）的数据。采用多变量logistic回归来检验DKPR回答结肠癌风险认知问题的知识缺陷解释（调整人口统计学、结直肠癌家族史）。比较（提示）和绝对口头感知结肠癌风险（提示，临床调查）；结肠癌风险和筛查知识，癌症和健康信息寻求行为和自我效能感（提示），以及计算能力（临床调查）。对结肠癌预防和筛查、癌症和健康信息寻求以及计算能力的了解越多，提供DKPR应答的几率就越低。这项研究是横断面的，这限制了推断因果方向的能力。现有数据集的使用限制了我们的变量选择。其他合理的假设也可以解释DKPR的反应。报告称不知道自己患结肠癌风险的人可能对癌症的认识较低，知识获取行为和技能也较差。健康行为研究可以从纳入有关DKPR对风险感知问题的反应的数据中受益，因为以这种方式作出反应的个人可能需要干预措施来解决潜在的癌症风险知识缺陷。
Perceived risk is a central theoretical construct in health behavior research. Participants’ “don’t know” responses to perceived risk items (DKPR) are usually excluded from analyses. Yet those who provide such responses may have unique cancer information needs. The hypotheses that DKPR responding may be due to cancer knowledge deficits or behavioral, skill, and attitudinal antecedents to knowledge deficits (information seeking, numeracy, and self efficacy respectively) were explored. Data from the 2005 Health Information National Trends Survey (HINTS, N=1,789), a United States population-based survey, and an urban, minority, primary care clinic survey (N=590) were analyzed. Multivariable logistic regressions were conducted to examine knowledge deficit explanations for responding DKPR to colon cancer risk perception questions (adjusting for demographics, family colorectal cancer history). Comparative (HINTS) and absolute verbal perceived risk of colon cancer (HINTS, clinic survey); knowledge of colon cancer risks and screening, cancer and health information seeking behavior and self efficacy (HINTS), and numeracy (clinic survey). Greater knowledge of colon cancer prevention and screening, cancer and health information seeking, and numeracy were each associated with lower odds of providing a DKPR response. The study was cross-sectional, which limits the ability to infer causal direction. The use of existing datasets limited our variable choices. Other plausible hypotheses may also explain DKPR responding. People who report that they don’t know their colon cancer risk may have low cancer knowledge and reduced knowledge acquisition behaviors and skills. Health behavior research could benefit from including data concerning DKPR responses to risk perception questions, as individuals who respond in this way may require interventions to address potential cancer risk knowledge deficits.
