A Pragmatic Trial on Actions For Collaborative Community Engaged Strategies for HPV (ACCESS-HPV)

February 2, 2026 updated by: Washington University School of Medicine
The present study expands on the investigators' earlier pilot study, outlined in ClinicalTrial ID#: NCT06010108. The Actions for Collaborative Community-Engaged Strategies for HPV (ACCESS-HPV), locally referred to as 4 Girls and Women (4GW) in Nigeria, seek to utilize a participatory crowdsourcing approach to enhance HPV prevention efforts among mother-daughter dyads. Specifically, the investigators aim to 1) develop a new combined HPV vaccination and HPV self-collection campaign for mothers/daughters using crowdsourcing open calls and learning community groups, 2) determine whether the co-developed final combined crowdsourced campaign will increase HPV vaccination rates among girls and promote HPV self-collection among mothers, and 3) estimate the impact and cost-effectiveness of the combined crowdsourced campaign in Nigeria.

Study Overview

Detailed Description

Following the completion of the open contests, designathons and boot-camp training, seven trained teams (with seven distinct interventions) were selected to undergo a 6-month pilot assessment in the community. Preliminary findings from the feasibility study suggest that crowdsourced interventions have the potential to impact uptake of HPV vaccinations among girls and HPV screening among mothers in Nigeria. As a result, the investigators identified key components from the top 2 interventions to form a single intervention that will be evaluated in the next phase of the research. Thus, the current protocol is focused on evaluating the effectiveness of a combined, crowdsourced intervention on HPV vaccination among girls and HPV screening among mothers in Nigeria.

Using a hybrid effectiveness-implementation type II pragmatic stepped-wedge cluster randomized control trial, this study will test the effectiveness of an implementation strategy bundle; a crowdsourced, tailored, community-engaged, mother-daughter HPV campaign on increasing uptake of HPV vaccination among girls aged 9-14 and HPV screening uptake among women aged 30-65 in Nigeria. The mother-daughter campaign will be tailored to local sites and conducted among 612 mother-daughter dyads (1,224 participants) recruited from 18 LGAs in six geopolitical zones of Nigeria. Upon enrollment, trained community health workers (two per LGA) will collect baseline data, and implement a mother-daughter day campaign that will provide education on cervical cancer control and access to onsite services for HPV vaccination and screening in a private area and engage mothers and daughters simultaneously to increase uptake of the services. A mixed-methods evaluative and iterative assessment will be conducted using Proctor's Implementation Outcomes Framework and the PEN-3 cultural model. The primary outcomes are the uptake of HPV preventive measures -HPV vaccination (one dose) among girls (ascertained by on-site records of vaccine uptake) and HPV self-collection completion among mothers (ascertained by laboratory receipt of self-collected specimens) within 6-months of trial enrollment. Pre-post effectiveness and cost of study components are embedded in the implementation and sustainment phases, with comparison to pre-implementation data assessed for each LGA.

  • Interventional Model: Sequential Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Mother-Daughter Day HPV Campaign
Each of the 18 local government areas begin as part of the control condition and are block-randomized into four waves in the pre-implementation phase, with each wave beginning 2 months after the start of the prior wave and lasting for 6 months. The local government areas will implement the intervention for 6 months, followed by a post implementation phase.

Pre-Implementation:

Identify, screen, and enroll mother-daughter dyads in the study to participate in the upcoming Mother-Daughter Day event on HPV vaccination and screening.

Complete baseline surveys with enrolled participants. Distribute reminder cards and send text messages to mother-daughter dyads who agree to participate in the mother-daughter day campaign.

Other Names:
  • Pre-Implementation Phase

Tailor and adapt to context: Mother-Daughter Day campaigns will be tailored and adapted to the local contexts within the 18 LGA.

Trained community health workers will implement the tailored Mother-Daughter Campaign by providing education on cervical cancer control and educational materials on HPV vaccination and HPV screening.

Engage mothers and daughters with on-site access to services: This includes offer of onsite vaccinations to girls by study nurse as well as offer of onsite self-collection screening kits to mothers and caregivers in a private area, along with instructions on how to use and return the sample.

Distribute gift bags with HPV vaccination cards, follow-up reminders, and linkage cards for participants with positive test results, as community health workers continue to provide onsite support and assistance.

Other Names:
  • Implementation Phase

A follow-up invitation will be sent to participate in a consultative phone call with study health workers to review self-collection results.

Participants with positive HPV test results will be linked to follow-up care and treatment.

Other Names:
  • Post-Implementation Phase

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intervention Acceptability
Time Frame: Measured at baseline, 3 months, and 6 months.
This will be measured using the Acceptability of Intervention Measure (AIM). The subscale is evaluated using a 5-point Likert scale, ranging from 1 to 5, with higher scores reflecting higher levels of acceptability. Cronbach alpha=0.85
Measured at baseline, 3 months, and 6 months.
Intervention Appropriateness
Time Frame: Measured at baseline, 3 months, and 6 months.
This will be assessed using the Intervention Appropriateness Measure (IAM). The subscale is evaluated using a 5-point Likert scale, ranging from 1 to 5, with higher scores indicating higher levels of appropriateness. Cronbach alpha=0.91
Measured at baseline, 3 months, and 6 months.
Intervention Feasibility
Time Frame: Measured at baseline, 3 months, and 6 months.
This will be assessed using the Feasibility of Intervention Measure (FIM). The subscale is rated on a 5-point Likert scale, 1 to 5, with higher scores indicating higher levels of feasibility.
Measured at baseline, 3 months, and 6 months.
Penetration (i.e., population dose)
Time Frame: Measured at baseline, 3 months, and 6 months.
The extent to which components of the mother-daughter HPV campaigns are institutionalized within participating local government area.
Measured at baseline, 3 months, and 6 months.
Implementation Fidelity
Time Frame: Measured at baseline, 3 months, and 6 months.
This will be assessed both quantitatively and qualitatively using the following four dimensions: (1) Frequency: number of intervention-related interactions; (2) Duration: length of each component of the intervention; (3) Content: the knowledge or behavioural change the combined intervention seeks to deliver to the mother/daughter dyads; and (4) Coverage: the number of mother/daughter dyads who receive the intervention as intended over the number of participants who are enrolled.
Measured at baseline, 3 months, and 6 months.
Sustainment
Time Frame: Measured at baseline, 3 months, 6 months, and 12 months
Measured using the Sustainment Measurement System Scale. Items will be rated on a 5-point Likert scale ranging from 1 (not at all) to 5 (all the time), with lower scores indicating lower levels of agreement while higher scores indicating higher levels of agreement.
Measured at baseline, 3 months, 6 months, and 12 months
