Who could benefit from this research
✓Could help
Ideal candidates are Indigenous (Yankton Sioux) women aged 25–65 who live on the Yankton Sioux Tribe Reservation in South Dakota and are due or overdue for cervical cancer screening.
✕Less likely to help
Women who are already up-to-date with screening, are younger than 25 or older than 65, do not live on the reservation, or lack reliable access to a smartphone/mobile web may not gain additional benefit from this intervention.
What this research studies
If I join, I'll be one of 120 Yankton Sioux women aged 25–65 who are randomly placed into one of two groups. Women in the app group will receive a culturally-tailored mobile web app that delivers personalized multimedia messages to encourage and support cervical cancer screening; the control group will get printed educational materials and later access to the app. The project uses community-based participatory methods and regular follow-up over four years to track whether women get Pap or HPV screening. The team will collect survey and screening data to compare outcomes between the two groups.
Why it matters
Potential benefit: If successful, the app could help more Indigenous women get screened earlier, reducing cervical cancer diagnoses and deaths in this community.
How similar studies have gone: Digital reminders and tailored messaging have improved screening in other groups, but a culturally-tailored mobile web app specifically for Yankton Sioux/Indigenous women is relatively new.
