This article examines the relationship between literacy and colorectal cancer (CRC) screening knowledge, beliefs, and experiences, with a focus on fecal occult blood tests (FOBTs). Participants were 975 patients in 8 Louisiana federally qualified health centers. Participants were 50 years of age or older and not up to date with CRC screening; approximately half (52%) had low literacy (less than a 9th-grade level). Participants with low literacy were less likely than were those with adequate literacy to be aware of advertisements promoting CRC screening (58.7% vs. 76.3%, p < .0001) or to believe it was very helpful to find CRC early (74.5% vs. 91.9%, p < .0001). The majority of participants had positive beliefs about the benefits of CRC screening using FOBTs. Participants with low literacy had more perceived barriers to FOBT completion and were more likely to strongly agree or agree that FOBTs would be confusing, embarrassing, or a lot of trouble; however, none of these remained significant in multivariate analyses controlling for relevant covariates. Confidence in being able to obtain an FOBT kit was high among those with low and adequate literacy (89.8% vs. 93.1%, respectively, p = .20); yet multivariate analyses revealed a significant difference in regard to literacy (p = .04) with low-literacy participants indicating less confidence. There was no significant difference by literacy in ever receiving a physician recommendation for CRC screening (38.4% low vs. 39.0% adequate, p = .79); however, multivariate analyses revealed significant differences in FOBT completion by literacy (p = .036). Overall, findings suggest that literacy is a factor in patients' CRC knowledge, beliefs, and confidence in obtaining a FOBT.
本文研究了读写能力与结直肠癌(CRC)筛查知识、信念和经验之间的关系,重点关注粪便潜血试验(FOBT)。参与者为路易斯安那州 8 家联邦合格健康中心的 975 名患者。参与者年龄在 50 岁或以上且未进行 CRC 筛查;约一半(52%)的人读写能力较低(低于 9 年级水平)。与读写能力足够的患者相比,读写能力较低的患者不太可能意识到宣传 CRC 筛查的广告(58.7%对 76.3%,p<.0001)或认为早期发现 CRC 非常有帮助(74.5%对 91.9%,p<.0001)。大多数参与者对使用 FOBT 进行 CRC 筛查的益处持有积极的信念。读写能力较低的参与者完成 FOBT 的障碍更多,更有可能强烈同意或同意 FOBT 会令人困惑、尴尬或很麻烦;然而,在控制相关协变量的多变量分析中,这些因素都没有显著意义。低读写能力和足够读写能力的参与者对获得 FOBT 试剂盒的信心都很高(分别为 89.8%和 93.1%,p=.20);然而,多变量分析显示,读写能力存在显著差异(p=.04),读写能力较低的参与者表示信心不足。在接受过医生推荐进行 CRC 筛查的患者中,读写能力没有显著差异(低读写能力 38.4%,足够读写能力 39.0%,p=.79);然而,多变量分析显示,FOBT 完成情况因读写能力而异(p=.036)。总的来说,研究结果表明,读写能力是患者 CRC 知识、信念和获得 FOBT 信心的一个因素。
