Trials of the specially-made video in North Carolina, USA, showed that the number of patients who agreed to undergo tests increased by 15 per cent.
The video gives patients information about screening options, and comes with a color-coded brochure and a chart marker.
Screening improved from 23 to 37%, when people saw the video.
The effect of watching the video was compared with the impact of patients watching a "placebo" video about automobile safety during the trial, which involved 250 adults in North Carolina.
Fecal occult blood testing or flexible sigmoidoscopy was ordered for 47.2% of intervention participants and 26.4% of controls. Screening tests were completed by 36.8% of the intervention group, but only 22.6% of the control group
Researcher Dr Michael Pignone said, "This new work is important because it shows that we can increase that number getting screening by at least 15 per cent. That's statistically significant as well as clinically important.
"It's important because it shows a change in the behavior of both patients and doctors. Too often doctors don't discuss colon cancer screening, and so most patients aren't even aware that they have the option of being screened."
