Guide to Colorectal Cancer Screening


This study tests interventions aimed to increase colorectal cancer (CRC) screening. Callers over age 50 to the Cancer Information Service (CIS) receive a brief educational message delivered by an information specialist followed by mailed untailored and tailored print materials.


Aim 1. Design, implement, and evaluate a proactive psychoeducational intervention to promote colorectal cancer screening using fecal occult blood tests (FOBT) and sigmoidoscopy.

Aim 2. Determine which subgroups benefit most from the proposed interventions.

Aim 3. Test the efficacy and cost-effectiveness of tailored print to promote behavior change.


4,014 callers to NCI's Cancer Information Service over age 50 who have not been completed colorectal cancer screening.
