Colorectal cancer (CRC) is the third leading cause of cancer death in the United States, and is largely preventable by CRC screening (CRCS). Participation in CRCS, however, is much lower than participation in other forms of preventive care. Many reasons for low rates of participation have been identified, and can be generally divided into provider- and patient-specific issues. Lack of a provider recommendation is a well-established and widely reported patient barrier to CRCS. Numerous patient-specific issues have been identified, ranging from fear of CRCS test results to lack of knowledge about individual risk for CRC and inadequate resources to complete CRCS. This article discusses the impact of patient attitudes and issues toward CRCS, with particular attention to modifiable psychosocial factors, the importance of patient preferences for one CRCS test over another, knowledge of CRC risk, and the impact of educational tools on patient compliance with CRCS.
结直肠癌（CRC）是美国癌症死亡的第三大主要原因，通过结直肠癌筛查（CRCS）可以在很大程度上预防。然而，CRCS 的参与率远低于其他形式的预防保健。已经确定了许多导致参与率低的原因，这些原因大致可以分为提供者和患者特定的问题。缺乏提供者的建议是一个既定的、广泛报道的患者接受 CRCS 的障碍。已经确定了许多患者特定的问题，从对 CRCS 检测结果的恐惧到对个人 CRC 风险的了解不足以及完成 CRCS 的资源不足。本文讨论了患者对 CRCS 的态度和问题的影响，特别关注可改变的社会心理因素、患者对一种 CRCS 检测方法的偏好、对 CRC 风险的认识以及教育工具对患者遵守 CRCS 的影响。
