About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Women who are self-identified AI women of the YST in SD
Women who are aged 25 to 65 years
Women who have not received any of the following cervical cancer screening tests: a Pap test within the past 3 years, primary HPV testing within the past 5 years, or HPV/Pap co-testing within the past 5 years.
Women who are willing to use their own mobile phone, iPad, tablets, and computers, or a mobile phone borrowed from the research team for the wPap intervention.
Disqualifiers
Women younger than 25 years or older than 65 years
Women who are currently up to date with cervical cancer screening according to recommended guidelines (Pap test within the past 3 years, primary HPV testing within the past 5 years, or HPV/Pap co-testing within the past 5 years)
Women with a prior diagnosis of cervical cancer
Women who have had a total hysterectomy that included removal of the cervix, without a history of high-grade precancerous lesions

Treatments tested in this trial
wPap Mobile Web App Intervention
BehavioralA 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.

Trial outcomes
Primary outcomes
1
Receipt of Cervical Cancer Screening
Completion of one of the three recommended screening methods by the ACS: primary HPV testing, co-testing, or Pap test alone. Completion of screening will be assessed using physician-signed verification of CC screening (Yes, No).
Time frame
6 monthsSecondary outcomes
1
Cervical Cancer Knowledge
Cervical cancer knowledge will be assessed using Taylor et al.'s Cervical Cancer Knowledge Scale, a modified previously validated 15-item true/false instrument. Scores range from 0 to 15, with scores calculated as the total number of correctly answered items. Higher scores indicate greater cervical cancer knowledge and represent a better outcome.
Time frame
Measured at baseline and 1 week post-intervention.2
Health Beliefs and Attitudes Toward Cervical Cancer Screening
Health beliefs and attitudes toward cervical cancer screening will be assessed using selected domains from the Champion's Health Belief Model Scale. Four domains consisting of 19 items will be used: perceived susceptibility, perceived seriousness, perceived benefits, and perceived barriers. Scores on the Champion's Health Belief Model Scale range from 1 to 76, with scores calculated by summing item responses within each domain. Higher scores indicate stronger endorsement of the respective health belief construct. Higher scores for perceived susceptibility, perceived seriousness, and perceived benefits represent more favorable beliefs and attitudes toward cervical cancer screening and indicate a better outcome, whereas higher scores for perceived barriers represent less favorable beliefs toward cervical cancer screening and indicate a worse outcome.
Time frame
Measured at baseline and 1 week post-intervention.3
Self-Efficacy for Cervical Cancer Screening
Self-efficacy for cervical cancer screening will be assessed using a modified version of Frerichs et al.'s Colorectal Cancer Screening Self-Efficacy Scale, adapted for this study to evaluate participants' confidence in obtaining cervical cancer screening. Scores on the Cancer Screening Self-Efficacy Scale range from 1 to 32, with higher scores indicating greater self-efficacy for completing cervical cancer screening behaviors and representing a better outcome.
Time frame
Measured at baseline and 1 week post-intervention.4
Intent to Undergo Cervical Cancer Screening
Intent to undergo cervical cancer screening will be assessed using two items informed by the Transtheoretical Model stages of change, which reflect increasing commitment toward adoption of screening behavior (precontemplation, contemplation, and preparation). The items assess: (1) participants' plan to receive cervical cancer screening in the next 6 months (Yes/No), and (2) level of intention to undergo cervical cancer screening in the future, rated on a 4-point scale ranging from today or within 1 month to within 1 year. Higher scores indicate greater intention and readiness to undergo cervical cancer screening.
Time frame
Measured at baseline and 1 week post-intervention.Sponsors and contacts
