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.

Interventions

BEHAVIORALRisk Assessment (CCRAT)

Patient receive personalized colorectal cancer risk assessment over the telephone by answering the questions as outlined in the National Cancer Institute Colorectal Cancer Risk Assessment Tool (https://ccrisktool.cancer.gov/calculator.html)

BEHAVIORALUsual Care (UC)

Patients receive standardized general information about colorectal cancer screening over the telephone.

Design outcomes

Primary

MeasureTime frameDescription
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT12 months after interventionAny 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

MeasureTime frameDescription
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT6 months after interventionAny 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)
Change in intention to screen at 6 months and 12 monthsImmediate after intervention, 6 months and 1 year after interventionDifferences in progressive behavioral stages of adoption from precontemplation to contemplation to preparation.
Colorectal cancer screening rates at 12 months as a function of CCRAT score12 months after interventionScreening 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

Other

MeasureTime frameDescription
Risk perception: Health Belief Model Likert ScaleImmediate after interventionDifferences in perception of one's own risk of colorectal cancer ranging from very unlikely (minimum) to very likely (maximum), with very unlikely representing the most favorable outcome of perceived risk and very likely representing the most unfavorable outcome of perceived risk.
Fear: Health Belief Model Likert ScaleImmediate after interventionPresence of fear of discovering colorectal cancer on performing screening test ranging from strongly disagree (minimum) to strongly agree (maximum), with strongly disagree representing the most favorable outcome of fear and strongly agree representing the most unfavorable outcome of fear.
