Abstract Body:
Purpose: Individuals at average risk for colorectal cancer (CRC) have multiple screening test options. Preference for a specific test modality may impact screening uptake. The current study examined: 1) the demographic and health belief characteristics of individuals with a preference for stool blood test (SBT) versus those with a preference for colonoscopy (COL); and 2) among those completing a screening test following receipt of one of three tailored interventions, the percentage of participants who completed a preference-concordant test, the demographic and health belief characteristics of those who completed a preference-concordant test, and the intervention effect on preference-concordant test receipt. Methods: Women (n=603) aged 50-75, at average CRC risk, not currently adherent to CRC screening guidelines, and with internet access were randomized to receive one of three tailored CRC screening interventions (i.e., web-based, phone counseling, or web plus phone counseling). Data were collected at baseline (i.e., demographics, health beliefs, stage of change [SOC]), during intervention receipt (i.e., health beliefs, SOC, test preference), and at 6 month follow-up (i.e., screening status).Results: Nearly two-thirds (64%) of participants preferred SBT. Significant differences in test preference were observed by age, intervention group, SOC for SBT, SOC for COL, and various health beliefs (i.e., perceived CRC screening benefits, self-efficacy for COL, and perceived barriers to both COL and SBT). At 6 months post-intervention, 230 participants (38%) completed CRC screening. Among those who completed post-intervention CRC screening, 84% completed a test concordant with their preference. Intervention group (p<.0001), age (p=.03), education (p=.02), and perceived CRC screening benefits (p=.03) were significantly associated with completion of a preference-concordant test. Conclusions: More than 80% of participants completed a preference-concordant test, a percentage higher than those reported in prior studies. Compared to participants completing a preference-discordant test, those completing a preference-concordant test were older, had completed less education, had lower perceived benefits of CRC screening, and were in the phone counseling only group.
