Participants talk by telephone with a Patient Navigator who is a trained nurse. The Patient Navigator determines if participants viewed the tailored DVD and answers any questions about the content. The Patient Navigator then provides telephone counseling on CRC and screening tests to: (1) increase knowledge, perceived benefits, and self-efficacy; (2) reduce barriers; (3) enhance access; and (4) provide social support.

Participants quality of bowel preparation is measured by the endoscopist during their colonoscopy using a modification of the Aronchick rating scale. The Aronchick scale rates quality as 1=excellent, 2=good, 3=fair, or 4=poor. Some endoscopists choose to grade quality more generally as adequate vs. inadequate. To accommodate this variation, bowel preparation ratings have been dichotomized into adequate (excellent, good, fair, or adequate ratings) vs. inadequate (poor or inadequate ratings). Adequate is scored as 1 and indicates better quality of bowel preparation than inadequate which is scored as 0.

Colonoscopy-related procedural anxiety is measured by self-report using the 6-item short form of the State Anxiety Scale of the State-Trait Anxiety Inventory. Each item is scored from 1 to 4 (1=not at all; 4=very much so) with higher scores indicating greater anxiety.

Satisfaction with the colonoscopy experience is measured by self-report using a single item developed by the research team. Satisfaction is rated from 1 to 4 where 1=not at all satisfied, 2=a little satisfied, 3=mostly satisfied, and 4=completely satisfied. Scores range from 1 to 4 with higher scores indicating greater satisfaction.

Number of participants completing a FIT is measured by electronic medical record review (EMR). Dates of FIT analysis are extracted from the EMR.

Change from baseline in knowledge of CRC and screening is measured at 6 months by self-report using a 9-item multidimensional scale. Each item is scored as 1=correct or 0=incorrect and summed to yield a scale score. Scores range from 0 to 9 with higher summated scores indicating greater knowledge of CRC and screening tests.

Patient Navigation: Participants talk by telephone with a Patient Navigator who is a trained nurse. The Patient Navigator determines if participants viewed the tailored DVD and answers any questions about the content. The Patient Navigator then provides telephone counseling on CRC and screening tests to: (1) increase knowledge, perceived benefits, and self-efficacy; (2) reduce barriers; (3) enhance access; and (4) provide social support.
