Narratives from similar others may be an effective way to increase important health behaviors. In this study, we used a narrative intervention to promote colorectal cancer screening. Researchers have suggested that people may overestimate barriers to colorectal cancer screening. We recruited participants from the US, ages 49-60 who had never previously been screened for colorectal cancer, to read an educational message about screening for the disease. One-half of participants were randomly assigned to also receive a narrative within the message (control participants did not receive a narrative). The narrative intervention was developed according to predictions of affective forecasting theory. Compared to participants who received only the educational message, participants who received the message along with a narrative reported that the barriers to screening would have less of an impact on a future screening experience. The narrative also increased risk perception for colorectal cancer and interest in screening in the next year.
类似他人的叙述可能是增加重要健康行为的有效方式。在这项研究中，我们使用叙述干预来促进结直肠癌筛查。研究人员认为，人们可能高估了结直肠癌筛查的障碍。我们从美国招募了从未接受过结直肠癌筛查的 49-60 岁的参与者，让他们阅读一篇关于该疾病筛查的教育信息。一半的参与者被随机分配到也接受信息中的叙述（对照组没有收到叙述）。叙述干预是根据情感预测理论的预测制定的。与仅接受教育信息的参与者相比，同时接受信息和叙述的参与者报告说，筛查障碍对未来的筛查体验影响较小。叙述还增加了对结直肠癌的风险感知以及对下一年筛查的兴趣。
