Correlates of Patient Intent and Preference on Colorectal Cancer Screening

Introduction Information is limited on patient characteristics that influence their preference among screening options and intent to be screened for colorectal cancer (CRC). A mechanistic pathway to intent and preference was examined through a formal mediation analysis. Methods From 2012 to 2014, a...

Description
Summary:Introduction Information is limited on patient characteristics that influence their preference among screening options and intent to be screened for colorectal cancer (CRC). A mechanistic pathway to intent and preference was examined through a formal mediation analysis. Methods From 2012 to 2014, a total of 570 adults aged 50–75 years were recruited from 15 primary care practices in Metro Detroit for a trial on decision aids for CRC screening. Confirmatory factor, regression, and mediation analyses were performed in 2015–2016 on baseline cross-sectional data. Main outcomes were patient intent and preference. Perceived risk and self-efficacy were secondary outcomes. Covariates included demographic information, health status, previous CRC screening experience, patient attitudes, and knowledge. Results Mean age was 57.7 years, 56.1% were women, and 55.1% white and 36.6% black. Women had 32% and 41% lower odds than men of perceiving CRC to be high/moderate risk (OR=0.68, 95% CI=0.47, 0.97, p =0.03) and having high self-efficacy (OR=0.59, 95% CI=0.42, 0.85, p =0.006), respectively. Whites had 63% and 47% lower odds than blacks of having high self-efficacy (OR=0.37, 95% CI=0.25, 0.57, p
