Project Summary/Abstract Colorectal cancer (CRC) remains one of the leading causes of cancer mortality in the United States for both men and women. Despite gains in CRC survival, African Americans (AAs) still fare worse in CRC incidence and mortality compared to European Americans (EA). Given that CRC incidence and mortality are directly related to CRC screening, this disparity can be attributed to the corresponding screening disparity wherein AAs are less likely to attend CRC screening compared to EAs. It follows that interventions to increase CRC screening intentions and subsequent CRC screening behaviors among AAs are instrumental in addressing the disparities in CRC incidence and mortality. Video-based interventions have been used effectively in a number of CRC screening interventions aimed at AAs’ CRC screening knowledge and behaviors. Additionally, interventions that target individuals’ perceptions of behavioral norms have successfully influenced people’s engagement across a number of health behaviors; however, despite their promise, norm- based messages have not been utilized for CRC screening interventions with AAs. For the current study we will use an experimental design to examine the extent to which injunctive and descriptive norm messages about CRC screening influence AAs’ normative perceptions and CRC screening intentions. We will also examine the extent to which racial identity and group-based medical mistrust moderate the effects of norm messages. Finally, we will explore the effects of norm messaging on CRC screening uptake. We will test the following specific aims: Aim 1: To (a) examine the unique effects of injunctive norm and descriptive norm messages on normative perceptions, CRC screening intentions, and (b) to explore whether the norm-messages foment stronger association between normative expectations and CRC screening intentions among a cohort of screen eligible AAs. We will recruit participants who are non-compliant with CRC screening. Aim 2: To (a) examine the moderating roles of racial identity and group-based medical mistrust and (b) explore the moderating role of perceptions of barriers and behavioral control on the effects of normative messaging. We will examine whether norm-based messages lead to more favorable normative perceptions and stronger effects of normative perceptions, among participants who more strongly identify as AAs, who harbor greater group-based medical mistrust and who perceive fewer behavioral impediments. Aim 3: To explore the effects of injunctive and descriptive norm messages on CRC screening uptake. We will explore whether participants who receive the norm-based interventions are more likely to request a CRC screening kit, and more likely to return the CRC screening kit, compared to participants who do not receive the intervention.

项目概要/摘要 结直肠癌 (CRC) 仍然是美国癌症死亡的主要原因之一 男性和女性。尽管结直肠癌存活率有所提高，但非裔美国人 (AA) 的结直肠癌生存率仍然较差 与欧洲美国人（EA）相比，发病率和死亡率。鉴于结直肠癌的发病率和死亡率 与 CRC 筛查直接相关，这种差异可归因于相应的筛查差异 其中，与 EA 相比，AA 参加 CRC 筛查的可能性较小。由此可见，干预措施要增加 AA 之间的 CRC 筛查意图和随后的 CRC 筛查行为有助于 解决结直肠癌发病率和死亡率的差异。已使用基于视频的干预措施 有效地开展了多项结直肠癌筛查干预措施，旨在提高 AA 的结直肠癌筛查知识和 行为。此外，针对个人对行为规范的看法的干预措施已成功 影响人们对多种健康行为的参与；然而，尽管他们做出了承诺，但规范- 基于消息的 AA 尚未用于 CRC 筛查干预。对于当前的研究我们 将使用实验设计来检查命令性和描述性规范信息的程度 有关 CRC 筛查的信息会影响 AA 的规范认知和 CRC 筛查意图。我们还将 研究种族认同和基于群体的医疗不信任在多大程度上调节了规范的影响 消息。最后，我们将探讨规范信息传递对 CRC 筛查的影响。我们将测试 以下具体目标： 目标 1： (a) 检查禁令性规范和描述性规范信息对 规范认知、CRC 筛查意图，以及 (b) 探讨规范信息是否 在规范期望和 CRC 筛查意图之间建立更紧密的联系 筛选合格的 AA 队列。我们将招募不符合 CRC 筛查要求的参与者。 目标 2： (a) 研究种族认同和基于群体的医疗不信任的调节作用 (b) 探讨障碍认知和行为控制对障碍影响的调节作用 规范的消息传递。我们将研究基于规范的信息是否会带来更有利的规范 认知和规范认知的更强影响，在那些更强烈地认同的参与者中 AA 持有更大的基于群体的医疗不信任，并且感知到的行为障碍更少。 目标 3：探讨禁令性和描述性规范信息对 CRC 筛查的影响 吸收。我们将探讨接受基于规范的干预措施的参与者是否更有可能 与那些要求 CRC 筛查试剂盒的参与者相比，更有可能归还 CRC 筛查试剂盒 不接受干预。
