Hypothesis
Does the number of colorectal cancer screening test options presented in a decision aid affect patient interest and preferences?
Conclusion
Offering different numbers of screening options does not significantly impact interest in colorectal cancer screening.
Supporting Evidence
- Participants showed no significant difference in screening interest after viewing the decision aids.
- Test preferences varied slightly between groups but did not reach statistical significance.
- Out-of-pocket costs influenced test choices more for the 2-option version.
Takeaway
This study found that whether people see two or five options for cancer screening doesn't really change how interested they are in getting screened.
Methodology
Participants aged 48-75 were randomized to view either a 5-option or a 2-option colorectal cancer screening decision aid.
Potential Biases
Potential bias due to self-reported preferences and hypothetical decision-making.
Limitations
The study had a small sample size and did not measure actual test completion.
Participant Demographics
Mean age 54, 58% women, 71% White, 24% African-American, 58% with at least a 4-year college degree.
