Background:
American Indian men are disproportionately impacted by prostate cancer (PC) compared to White men and experience the worst PC outcomes of any racial or ethnic group. To address these disparities, it is important to better understand American Indian men's preferences regarding PC screening.
Objective:
The objectives of this study are as follows: (1) conduct a literature review, followed by qualitative, culturally responsive formative research with American Indian men, (2) develop and field a discrete choice experiment (DCE) survey to elicit the preferences of American Indian men toward PC screening, and (3) identify feasible, culturally appropriate, preference-concordant screening strategies that are targeted for American Indian men.
Methods:
In this protocol, a scoping literature review to identify previous PC DCEs has been created. We will follow that review by conducting rigorous, theoretically grounded qualitative work to identify plausible DCE attributes and attribute levels among men from the Lumbee Tribe in North Carolina. We will pilot the DCE among Lumbee men to assess cultural responsiveness and comprehension of the choice context and choice tasks. Finally, the DCE methodology will be used to elicit the PC screening preferences among 100 Lumbee men between the ages of 40 and 69 years. Choice data will be analyzed using mixed logit models, and trade-offs will be described using marginal rates of substitution.
Results:
The study was funded in 2024. Formative qualitative research is still ongoing. DCE data collection is expected to start in April 2026 and end in June 2026.
Conclusions:
This will be the first study to use a culturally responsive approach to DCE development in an indigenous population. The findings of this study can be used to educate providers regarding culturally responsive PC screening and to inform the design of interventions to increase preference-concordant PC screening in American Indian men.

Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
