结直肠癌（CRC）是妇女癌症死亡的第三大原因。筛查可以预防CRC的发展或在可以有效治愈时诊断早期疾病，但现有的筛查方法未得到充分利用。在这项研究中，我们研究了一个更新的健康信念模型来解释CRC筛查依从性的效用。本研究包括280名老年妇女寻求常规乳房X光检查在一个大的，城市乳腺诊断设施。总体而言，50%的妇女遵守CRC筛查指南。多元回归分析表明，自我效能，医生的建议，感知的好处和感知的障碍，以筛选占40%的变异CRC筛查依从性。然而，没有证据表明两个中介模型的感知利益和感知障碍的主要机制，推动坚持CRC筛查。这些发现可能为未来的理论研究以及旨在增加CRC筛查行为的临床干预提供信息。
Colorectal cancer (CRC) is the third leading cause of cancer mortality among women. Screening can prevent the development of CRC or diagnose early disease when it can effectively be cured, however existing screening methods are underutilized. In this study, we examined the utility of an updated Health Belief Model to explain CRC screening adherence. The present study included 280 older women seeking routine mammography at a large, urban breast diagnostic facility. Overall, 50% of women were adherent to CRC screening guidelines. Multiple regression indicated that self-efficacy, physician recommendation, perceived benefits of and perceived barriers to screening accounted for 40% of variance in CRC screening adherence. However, there was no evidence for two mediational models with perceived benefits and perceived barriers as the primary mechanisms driving adherence to CRC screening. These findings may inform both future theoretical investigations as well as clinical interventions designed to increase CRC screening behavior.
