项目摘要

DESCRIPTION (provided by applicant): Continued efforts are needed in the U.S. to increase colorectal cancer (CRC) screening. For many people, their decision to screen will be influenced by information found on the internet. Such influential information can include receipt of tailored CRC feedback. However, a major concern is that receipt of online tailored CRC risk feedback that people interpret as being low risk can demotivate screening. Yet, as argued here, both higher and lower perceived risk can motivate screening when paired with appropriate persuasive messaging. To this end, pairing tailored CRC risk feedback with gain or loss framing - messages that highlight the benefits of screening (i.e., gain) or the costs of not screening (i.e, loss) - can be a potent combination to promote screening. As informed by Prospect Theory, matching of feedback of higher CRC risk with loss-framed messages as well as lower risk feedback with gain-frame messages should be more persuasive to motivate screening than the opposite pairings (i.e., mismatch). Yet no research has tested the matching between tailored CRC risk feedback and message framing to influence CRC screening. The primary goal of this study is to test the matching between level of comparative risk (i.e., how one's risk compares to others) and framing and mediators of effects in the context of individuals who obtain CRC risk and framing messages online (i.e., Internet). To simulate this online environment, using a firm the specializes in the conduct of web-based studies, we will obtain a sample of 760 individuals ages 50-75 who have never been screened for CRC. Individuals will review online information about CRC screening and receive tailored feedback as to their CRC risk factors and level of comparative risk. Participants within each stratum of comparative risk will then be randomized to receive messages either about the benefits of CRC screening (gain-frame) or the disadvantages of not screening (loss-frame). They will complete an immediate post-intervention survey assessing intentions to screen and hypothesized mediators and provide data six months later about screening behaviors. This study addresses the unresolved and neglected problem of what are the best tailored messages to give people at lower and higher CRC that can promote CRC screening. To this end, this study will be the first to explore in the online context the matching between tailored CRC risk feedback and message framing to influence CRC screening intentions, behaviors, and potential mediators of effects. This undertaking is important because it is yet unclear what best strategies to use to deliver tailored CRC risk feedback via the Internet to influence CRC screening.

描述（由申请人提供）：美国需要继续努力增加结直肠癌（CRC）筛查。对于许多人来说，他们的决定将受到互联网上发现的信息的影响。这种有影响的信息可以包括接收定制的CRC反馈。然而，一个主要的问题是，收到在线定制的CRC风险反馈，人们解释为低风险可以使筛查失去动力。然而，正如这里所说的，当与适当的说服性信息相结合时，较高和较低的感知风险都可以激励筛选。为此，将定制的CRC风险反馈与增益或损失框架配对-突出筛选益处的消息（即，收益）或不筛查的成本（即损失）-可以是促进筛查的有效组合。如由前景理论所告知的，较高CRC风险的反馈与丢失帧消息的匹配以及较低风险反馈与增益帧消息的匹配应当比相反配对（即，失配）。然而，还没有研究测试定制的CRC风险反馈和消息框架之间的匹配来影响CRC筛查。本研究的主要目标是测试比较风险水平（即，一个人的风险与其他人相比如何）以及在获得CRC风险和在线框架信息的个体的背景下的影响的框架和介导者（即，互联网）。为了模拟这种在线环境，我们使用一家专门从事基于网络的研究的公司，我们将获得760名年龄在50-75岁之间从未接受过CRC筛查的个体的样本。个人将审查有关CRC筛查的在线信息，并收到针对其CRC风险因素和相对风险水平的定制反馈。然后将每个相对风险层内的参与者随机接受关于CRC筛查的益处（增益帧）或不筛查的缺点（丢失帧）的信息。他们将立即完成干预后调查，评估筛选和假设中介的意图，并在六个月后提供有关筛选行为的数据。这项研究解决了未解决和被忽视的问题，什么是最适合的消息，给人们在较低和较高的CRC，可以促进CRC筛查。为此，本研究将第一个探索在在线环境中定制CRC风险反馈和消息框架之间的匹配，以影响CRC筛查的意图，行为和潜在的影响介质。这项工作很重要，因为目前还不清楚使用什么最佳策略通过互联网提供量身定制的CRC风险反馈，以影响CRC筛查。
