This observational study uses a time-sequential randomized design of 1440 veterans, stratified by age (<50, 50-75, >75), who have upcoming appointments in primary care clinics at the 4 study sites. Patients who are eligible (i.e., have at least 20/50 vision and are not demented) are asked to participate in a face-to-face structured survey with a study interviewer. The survey includes demographic data, functional status, social support, measures of attitudes and beliefs about health care providers, health insurers, medical care and the Short-Test of Functional Health Literacy in Adults (S-TOFHLA). For those between ages 50-75, knowledge of and attitudes towards CRC screening are also measured. Survey data are then matched to data from the CRC QUERI screening assessment and surveillance data system (CRS 02-162-1) to evaluate screening adherence.
