Does Knowing One's Estimated Colorectal Cancer Risk Influence Screening Behavior?

Not Applicable

Completed

• Conditions: Colorectal Cancer

• Registration Number: NCT03819920
• Lead Sponsor: Stanford University

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT	12 months after intervention	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)

Secondary Outcome Measures

Name	Time	Method
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT	6 months after intervention	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)
Colorectal cancer screening rates at 12 months as a function of CCRAT score	12 months after intervention	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
Change in intention to screen at 6 months and 12 months	Immediate after intervention, 6 months and 1 year after intervention	Differences in progressive behavioral stages of adoption from precontemplation to contemplation to preparation.
