Motivating Factors Associated With Receipt of Asymptomatic Colonoscopy Screening

Background: Colonoscopy is the preferred screening method for colorectal cancer (CRC). This study aimed to identify factors motivating a beneficial health behavior, that is, the decision to complete a colonoscopy. Methods: We surveyed 91 primarily urban minority health care workers who were ineligible for a large randomized controlled trial due to self-reported asymptomatic colonoscopy screening. Participants were asked an open-ended question about what made them get screened. Responses were classified as external or internal motivations. Results: The most commonly reported external motivation was a primary care physician′s recommendation (n = 60, 65.9%). Other external motivations were familiarity with CRC or polyps through family or work (n = 16, 17.6%) and pressure from relatives or friends (n = 8, 8.8%). Seventeen respondents were deemed self-motivated; these individuals were more likely have income over $50K/year (P < 0.05) and to be US born (P = 0.05); they were more likely to mention being age-appropriate for screening (P < 0.05); knew more people who had colonoscopies (P < 0.001); they were less likely to believe that most of the age-appropriate population in New York City has been screened (P < 0.01) and less likely to be deterred from colonoscopy by work schedule (P < 0.001) or by having to take a powerful laxative (P < 0.001).Conclusions: A primary care physician′s recommendation may be the most prevalent motivating factor in patients′ decisions to receive a colonoscopy, but a subgroup seeks CRC screening on their own. Analysis of the motivations of individuals who have sought colonoscopy screening may offer useful insights into motivating those who have not
