We report how a four-group risk communication intervention targeted to individuals in the carpentry trade affected their perceived causes (i.e., attributions) for increased colorectal cancer (CRC) risk. The intervention varied the amount of information presented on CRC risk factors and whether participants received tailored feedback on their risk factors. In baseline and 3-month follow-up telephone surveys, carpenters (N = 860) reported their perceived absolute and comparative CRC risks, perceived causes for increased CRC risk, and knowledge of CRC risk factors. At follow-up, neither the type or amount of information provided, nor the use of tailoring, appreciably and consistently affected whether participants mentioned their specific risk factor (e.g., lifestyle, occupational) emphasized in their intervention information. Furthermore, attributions did not affect CRC risk perceptions. These results suggest that participants do not integrate sufficiently CRC risk factor information into their conceptualizations of CRC risk, and that more effective methods are needed to contextualize risk factors information to achieve the goal of modifying CRC risk perceptions.
我们报告了一项针对木工行业从业者的四组风险沟通干预措施如何影响他们对结直肠癌（CRC）风险增加的感知原因（即归因）。该干预措施在呈现的CRC风险因素信息量以及参与者是否收到关于其风险因素的个性化反馈方面有所不同。在基线和3个月随访电话调查中，木匠（N = 860）报告了他们感知的绝对和相对CRC风险、对CRC风险增加的感知原因以及对CRC风险因素的了解。在随访时，所提供信息的类型或数量以及个性化的使用，均未明显且持续地影响参与者是否提及在其干预信息中强调的特定风险因素（例如生活方式、职业）。此外，归因并未影响CRC风险认知。这些结果表明，参与者未充分将CRC风险因素信息整合到他们对CRC风险的概念化认知中，并且需要更有效的方法来将风险因素信息情境化，以实现改变CRC风险认知的目标。
