Interventions

  • wPap Mobile Web App Intervention — BEHAVIORAL
    A seven-day mobile web app program providing culturally tailored educational modules on cervical cancer risk, screening guidelines, and health promotion strategies. Participants download the app, complete daily modules, and complete pre- and post-tests to assess knowledge, attitudes, self-efficacy, and intention to undergo cervical cancer screening. Health navigator support is provided throughout the intervention.

Study Details

The overarching goal of this study is to increase cervical cancer (CC) screening rates among Indigenous women in the U.S. Specifically, the study aims to develop and evaluate a culturally tailored, multilevel, multimedia mobile web app intervention (wPap) for women of the Yankton Sioux Tribe (YST) living on the YST Reservation in South Dakota. The wPap intervention will be tested in a randomized clinical trial (RCT) involving 120 YST women aged 25-65. Participants will be randomly assigned to either: (a) the wPap intervention group (n = 60), receiving personalized, culturally tailored multilevel multimedia messages through a mobile web app along with health navigator support, or (b) a waitlist control group (n = 60), receiving printed educational materials on cervical cancer and screening guidelines along with health navigator support. The intervention will last seven days, with assessments conducted at baseline, one week post-intervention, and six months post-intervention via surveys and telephone follow-up. The study tests the following hypotheses: (H1) women in the wPap intervention group will achieve higher CC screening rates than the waitlist control group; (H2) the wPap group will demonstrate greater improvements in knowledge, attitudes/beliefs, self-efficacy, and intention to undergo CC screening; and (H3) the wPap group will report higher satisfaction and acceptance of the intervention compared with the waitlist control group. Findings will inform the feasibility, acceptability, and efficacy of mobile web app interventions tailored to Indigenous communities to improve CC screening.

Arms

  • Experimental: Experimental: Intervention
    Participants in this arm will receive a seven-day mobile web app intervention designed to promote cervical cancer (CC) screening. Participants are required to download the wPap mobile app and complete daily educational modules over the seven-day period. Each module includes information about CC risk factors, screening guidelines, and health promotion strategies tailored to the cultural context of the Yankton Sioux Tribe. Participants will complete pre- and post-tests to assess knowledge, attitudes, self-efficacy, and intent to undergo screening. The intervention encourages participants to increase awareness of CC screening needs and supports engagement with available health services.
  • No Intervention: Control group
    Participants are randomized to control arm where they are give an education brochure. There are pre and post tests to complete.
