This study is designed to examine the impact of telephone-based colorectal cancer risk assessment on colorectal screening attitudes and behavior among previously unscreened adults ages 50 to 75.
Colorectal cancer (CRC) remains the 3rd most common cancer in the US. Most CRCs are preventable, but screening participation remains suboptimal. Several factors have been associated with screening compliance, such as perception of CRC risk. Here we study the impact of telephone-based administration of the National Cancer Institute Colorectal Cancer Risk Assessment Tool (CCRAT) compared to usual care.

Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT
Any CRC screening test completed including stool tests (FOBT (fecal occult blood test), FIT (immunochemical test for fecal blood), stool DNA test), colonoscopy, flexible sigmoidoscopy, double contrast barium enema, CT colonography (virtual colonoscopy)
Time frame: 12 months after intervention
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT
Any CRC screening test completed including stool tests (FOBT (fecal occult blood test), FIT (immunochemical test for fecal blood), stool DNA test), colonoscopy, flexible sigmoidoscopy, double contrast barium enema, CT colonography (virtual colonoscopy)
Time frame: 6 months after intervention
Change in intention to screen at 6 months and 12 months
Differences in progressive behavioral stages of adoption from precontemplation to contemplation to preparation.
Time frame: Immediate after intervention, 6 months and 1 year after intervention
Colorectal cancer screening rates at 12 months as a function of CCRAT score
Screening completion at 12 months will be compared between the 3 tertiles of CCRAT score in the intervention group to determine whether there is any relationship between absolute CCRAT score and screening completion
Time frame: 12 months after intervention
