Factors associated with colorectal cancer screening decision stage

Abstract Objective This paper reports on factors associated with colorectal cancer (CRC) screening decision stage (SDS) in screening-eligible primary care patients. Methods Baseline telephone survey data (i.e., sociodemographic background, CRC screening perceptions, and SDS) were obtained for 1515 patients in a randomized behavioral intervention trial. Respondents reported SDS, a measure of proximity to actual screening, after listening to descriptions of screening stool blood testing and flexible sigmoidoscopy as had never heard of (NHO), were not considering or were undecided (NCU), or decided to do (DTD) each test. Polychotomous regression analyses were performed to differentiate participants by SDS. Results At baseline, SDS was distributed as follows: NHO (8%), NCU (41%), and DTD (51%). We found that individuals who had DTD compared to those who were NCU about screening were older (OR = 0.64), had prior cancer screening (OR = 1.43), believed screening is important (OR = 3.44), and had high social support (OR = 2.49). Persons who were NCU compared to NHO participants were female (OR = 2.18), were white (OR = 2.35), had prior cancer screening (OR = 2.81), and believed screening is important (OR = 2.44). Conclusions Prior screening and belief in screening importance were found to be consistently associated with SDS across comparisons, while older age, gender, race, and social support were not.
