Abstract

Objective: Health information avoidance is a critical barrier to reaching people with health messaging and, ultimately, decreases population-level uptake of life-saving prevention behaviors such as colorectal cancer (CRC) screening. We conducted a preregistered double-blinded experiment testing the efficacy of brief narrative video interventions designed to promote CRC screening by mitigating either of two known causes of health information avoidance: low self-efficacy and low perceived control over health outcomes.

Method: Participants (N = 776, 45-75 years, not adherent to CRC screening, no history of CRC) recruited from Prolific, an online participant pool, were randomly assigned to view an intervention video (perceived control promoting colonoscopy, self-efficacy promoting colonoscopy, self-efficacy promoting fecal immunochemical test) or control video (food safety attentional control video, CRC informational video). Afterward, participants completed assessments of CRC information seeking, screening attitudes, and screening intentions.

Results: Compared to an attentional control video, all three intervention videos improved all four outcomes; they were effective for people high in CRC information avoidance and those who were not. Effects for self-efficacy videos were mediated through increased self-efficacy. Effects for perceived control videos were not mediated through increased health locus of control. Interactions between video condition and avoidance were not significant. Intervention videos were not more effective than the informational CRC video.

Conclusions: Only 58% of the U.S. adult population is CRC screening adherent, and the rate is lower for people who avoid CRC information. By increasing CRC information seeking, positive CRC screening attitudes, and CRC screening intentions, these publicly available videos could have widespread public health impact.

简短的视频干预增加了不了解结直肠癌信息的人的筛查意愿。

目的：健康信息回避是向人们传递健康信息的一个关键障碍，最终会降低人群对挽救生命的预防行为（如结直肠癌筛查）的接受程度。我们进行了一项预先注册的双盲实验，测试了简短叙事视频干预的有效性，该干预旨在通过减轻健康信息回避的两个已知原因之一来促进结直肠癌筛查：低自我效能感和对健康结果的低感知控制。方法：从在线参与者池中招募参与者（N = 776, 45-75岁，未坚持结直肠癌筛查，无结直肠癌病史），随机分配观看干预视频（感知控制促进结肠镜检查，自我效能促进结肠镜检查，自我效能促进粪便免疫化学检查）或对照视频（食品安全注意控制视频，结直肠癌信息视频）。之后，参与者完成了CRC信息寻求、筛查态度和筛查意图的评估。结果：与注意力控制视频相比，所有三个干预视频都改善了所有四个结果；对CRC信息回避程度高的人群和CRC信息回避程度低的人群均有效。自我效能录像的效果是通过自我效能的增加来中介的。知觉控制录像的效果不通过健康控制点的增加来调节。视频条件与回避的交互作用不显著。干预视频并不比信息CRC视频更有效。结论：只有58%的美国成年人遵循CRC筛查，而对于避免CRC信息的人群，这一比例更低。通过增加CRC信息的寻求，积极的CRC筛查态度和CRC筛查意图，这些公开的视频可以产生广泛的公共卫生影响。（PsycInfo Database Record (c) 2025 APA，版权所有）。
