Background:
Low public awareness is an important barrier for colorectal cancer screening participation.
Aim:
To evaluate the impact of educational intervention on the health behavior process, patient knowledge and compliance with colorectal cancer screening in the average-risk population.
Methods:
158 subjects (aged 50-79 years) were randomly assigned either to watch a non-medical video or a colorectal cancer educational video. Before and after watching the experimental or control videotape, participants completed a five-item questionnaire that assessed their knowledge about risk factors for colorectal cancer, age of risk, warning symptoms, 5-year prognosis, and incidence. Subjective risk perception for developing colorectal cancer, barriers or benefits of screening, and intention to be screened were also investigated. Finally, subjects received a faecal occult blood test kit and were requested to use and return it within 2 weeks.
Results:
Participants in the video-based intervention group showed significant improvement in knowledge of colorectal cancer scores (P<0.001) and decreased barrier scores. The intervention group returned significantly more faecal occult blood tests than controls (69.6% vs. 54.4%, P=0.035). The intervention had a positive effect on modifying attitudes and intention to take part in screening. Additionally, the intervention was a predictor of compliance (OR 2.0; 95% CI=1.02-3.84, P=0.044).
Conclusion:
Video-based intervention significantly reduced barriers to screening and improved participant awareness and compliance with colorectal cancer screening with faecal occult blood test.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
