We developed a training program for five health center interpreters fluent in eight different languages. Patients randomly assigned to the study intervention receive an introductory letter in their native language. During the initial contact the navigator educates patients about CRC screening and explores patients' barriers to CRC screening. Based on results from a qualitative study conducted at in 2006, we developed interventions to overcome individual barriers to CRC screening tailored to each individual patient. Specific interventions include elucidation of culturally-specific health beliefs; teaching about cancer risk, colonoscopy, and colon prep administration; and help with appointment-making and transport.
