There have been few studies of tailored interventions to promote colorectal cancer (CRC) screening.
We conducted a randomized trial of a tailored, interactive intervention to increase CRC screening.
Patients 50-70 years completed a baseline survey, were randomized to one of three groups, and attended a wellness exam after being exposed to a tailored intervention about CRC screening (tailored group), a public web site about CRC screening (web site group), or no intervention (survey-only group). The primary outcome was completion of any recommended CRC screening by 6 months.
There was no statistically significant difference in screening by 6 months: 30%, 31%, and 28% of the survey-only, web site, and tailored groups were screened. Exposure to the tailored intervention was associated with increased knowledge and CRC screening self-efficacy at 2 weeks and 6 months. Family history, prior screening, stage of change, and physician recommendation moderated the intervention effects.
A tailored intervention was not more effective at increasing screening than a public web site or only being surveyed.
针对促进结直肠癌（CRC）筛查的定制干预措施，研究甚少。
我们开展了一项随机试验，评估了一种定制的互动干预措施，以提高 CRC 筛查率。
50-70 岁的患者完成基线调查，随机分为三组，并在接受有关 CRC 筛查的定制干预（定制组）、有关 CRC 筛查的公共网站（网站组）或无干预（仅调查组）后接受健康检查。主要结局是在 6 个月内完成任何推荐的 CRC 筛查。
6 个月时筛查率无统计学显著差异：仅调查组、网站组和定制组分别有 30%、31%和 28%的患者接受了筛查。在 2 周和 6 个月时，接触定制干预与知识和 CRC 筛查自我效能的增加相关。家族史、既往筛查、改变阶段和医生建议调节了干预效果。
与公共网站或仅接受调查相比，定制干预并不能更有效地提高筛查率。
