BACKGROUND: In the United States, compliance with colorectal cancer (CRC) screening recommendations remains suboptimal. Professional organizations advocate use of shared decision making in screening test discussions, but strategies to facilitate informed choice in CRC screening have not been well elucidated. OBJECTIVE: The objectives of the study were to determine screening test preference among colonoscopy-naive adults after considering a detailed, written presentation of fecal occult blood testing (FOBT) and colonoscopy and to assess whether their preferences are associated with demographic characteristics, attitudes, and knowledge. DESIGN: The design of the study was a cross-sectional survey. PARTICIPANTS: Colonoscopy-naive supermarket shoppers age 40-79 in low- and middle-income, multiethnic neighborhoods in Denver, CO, reviewed a detailed, side-by-side description of FOBT and colonoscopy and answered questions about test preference, strength of preference, influence of physician recommendation, basic knowledge of CRC, and demographic characteristics. MEASUREMENTS AND MAIN RESULTS: Descriptive statistics characterized the sample, and bivariate and multivariable logistic regression analyses identified correlates of screening test preference. In a diverse sample of 323 colonoscopy-naive adults, 53% preferred FOBT, and 47% preferred colonoscopy for CRC screening. Individuals of Latino ethnicity and those with lower educational attainment were more likely to prefer FOBT than non-Latino whites and those with at least some college. Almost half of the respondents felt very strongly about their preferences, and one third said they would adhere to their choice regardless of physician recommendation. CONCLUSION: After considering a detailed, side-by-side comparison of the FOBT and colonoscopy, a large proportion of community-dwelling, colonoscopy-naive adults prefer FOBT over colonoscopy for CRC screening. In light of professional guidelines and time-limited primary care visits, it is important to develop improved ways of facilitating informed patient decision making for CRC screening.
