Abstract
This study investigated predictors of overall and test-specific colorectal cancer screening (CRCS). Stool blood test (SBT) and/or colonoscopy screening were offered to primary care patients in two randomized controlled trials which assessed the impact of behavioral interventions on screening. Data were obtained through surveys and electronic medical records. Among 1942 participants, 646 (33%) screened. Exposure to interventions was associated with higher overall CRCS by twofold to threefold; older age, African American race, being married, and having a higher screening decision stage were also associated with higher overall CRCS (odds ratios = 1.30, 1.31, 1.34, and 5.59, respectively). Intervention, older age, female gender, and being married were associated with higher SBT adherence, while preference for colonoscopy was associated with lower SBT adherence. Intervention and higher decision stage were associated with higher colonoscopy adherence, while preference for SBT was associated with lower colonoscopy adherence. Among older individuals, African Americans had higher overall CRCS than whites, but this was not true among younger individuals (interaction p = .041). The higher screening adherence of African Americans over whites was due to stronger screening with a non-preferred test, i.e., higher SBT adherence only among individuals who preferred colonoscopy and higher colonoscopy adherence only among individuals who preferred SBT. Intervention exposure, sociodemographic background, and screening decision stage predicted overall CRCS adherence. Gender and test preference also affected test-specific screening adherence. Interactions involving race and test preference suggest that it is important to provide both colonoscopy and SBT screening options to patients, particularly African Americans.
