The videos (“decision aids”) below were used in a research study comparing different ways of educating average risk patients about colorectal cancer (”colon cancer”) screening. All participants viewed the “General Decision Aid,” which presents information about colon cancer and two of the most popular screening tests.
Half the participants also viewed a “personalized risk message” that told them the chance they currently have a large polyp or colon cancer, called an “advanced colorectal neoplasm” (ACN). The chance of having an ACN is estimated from the person’s gender, age, smoking history, waist circumference, and whether any family members had colon cancer. For more information about how the chance of having an ACN is calculated, see https://estimatingriskofacn.iu.edu/.
