Colorectal cancer screening among the public: knowledge, attitudes, and the perceived barriers.

Colorectal cancer (CRC)1 screening tests help in early detection of CRC and improve disease prognosis. This study aimed to assess knowledge, attitude, and barriers to CRC screening and the associated factors among the general population in Jordan. A validated self-administered online survey was distributed on 1542 individuals in Jordan. The participants (n = 1542) reported several barriers and demonstrated insufficient knowledge but positive attitude towards CRC screening. Older age (OR = 1.021, 95% CI = 1.010-1.032, P < 0.001), working in medical field (OR = 3.198, 95% CI = 2.499-4.092, P < 0.001), family history of cancer (OR = 1.248, 95% CI = 1.002-1.555, P < 0.05), and knowing someone with CRC (OR = 1.601, 95% CI = 1.186-2.161, P < 0.01) were significantly associated with higher knowledge. Personal history of CRC (OR = 3.157, 95% CI = 1.188-8.387, P < 0.05), and high knowledge of CRC (OR = 2.795, 95% CI = 2.242-3.484, P < 0.001) were significantly associated with the positive attitude. Future healthcare programs should devise effective techniques to improve public understanding and perception of CRC screening and overcome the identified barriers.
