Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Antigen self-testing kits are more available at this stage in the pandemic, but among vulnerable populations, use is still low and instructions for antigen testing are not typically designed for low health literacy populations. Studies are needed to explore access and use of antigen tests among vulnerable populations and examine if low-health-literacy-designed interventions improve COVID-19 testing decisions and behaviors. This study will focus on understanding factors associated with rapid COVID-19 testing, specifically. The primary objectives of the embedded study are to 1) Determine the effectiveness of community-level intervention using door-to-door recruitment and education in increasing COVID-19 testing and 2) Compare the effectiveness of the CHW- Facilitated Self-Sampling Intervention (FSSI) vs. CHW Testing Navigation Intervention (TNI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The pandemic landscape and people's experiences with testing, infection, and vaccination have changed dramatically over the past two years. Vaccines have become available, testing access in local communities has waxed and waned, and attitudes toward COVID-19 severity and susceptibility have shifted. Navigating the testing-decision landscape is confusing to the public (test availability for free versus charged or requiring insurance; testing and vaccination locations change; PCR versus antigen testing; home tests versus clinically delivered; symptom-based testing, exposure-driven testing, serial testing, resources to trust or not trust, etc.).

This study, referred to as the embedded study, builds off a broader population-based group randomized controlled trial (RCT) to evaluate the effects of a Facilitated Self-Sampling Intervention and Testing Navigation Intervention on testing behaviors. The embedded study will randomly select and assign priority block groups from the RCT to one of three arms - FSSI (n=16), TNI (n=16), or Control (n= 32). The allocation will be at a 2:1:1 rate across the three regions Houston/Harris County, South Texas, and Northeast Texas respectively. Community Health Workers will systematically sample and recruit 20 individuals from each PBG using a random start procedure. Study participants in the intervention arms will be enrolled, complete a baseline survey, receive a brief educational intervention, and complete a follow-up survey. Participants in the control arm will complete a baseline and follow-up survey.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Facilitated Self-Sampling Intervention (FSSI)

Participants in the FSSI arm will receive education on COVID-19 testing and be provided with rapid antigen tests. Participants will also receive pre and post surveys.

Group Type EXPERIMENTAL

Facilitated Self-Sampling Intervention (FSSI)

Intervention Type BEHAVIORAL

CHWs will consent and enroll participants to the FSSI from the randomized PBGs. FSSI will consist of Community Health Worker (CHW) delivered education intervention about COVID-19 testing at a home visit. In addition, the participant will receive a batch of 4 rapid antigen tests which can be shared with people in the household or other close contacts if needed. The CHWs will provide low-literacy instructions for administering the tests, including print and video. The CHWs will also provide guidance if they tested positive (e.g. quarantine, notify contacts, wearing a mask). The CHWs will also be available by phone to the participants for any follow-up questions. CHW will follow-up via text and phone with the participants during the two months post intervention. In addition to the intervention, the participants will be asked to complete the pre and post test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.

Testing Navigation Intervention (TNI).

Participants in the TNI arm will receive COVID-19 testing education and be navigated to PCR testing sites. Participants will also receive pre and post surveys.

Group Type EXPERIMENTAL

Testing Navigation Intervention (TNI).

Intervention Type BEHAVIORAL

CHWs will consent and enroll participants to the TNI from the randomized PBGs. The TNI will consist of CHW-led intervention at a home visit where they will provide low health literacy materials about how and when to conduct a COVID 19 test (including antigen and PCR) using a decision tree model and provide navigation to nearby PCR testing sites, locations to purchase antigen tests and support in accessing federal government antigen tests if not already obtained by the participant. In addition to the intervention, the participants will be asked to complete the pre and post-test surveys. Post surveys will be administered online or over the phone two months after the initial intervention.

Control

Participants in the Control Group arm will receive a CDC-designed COVID-19 testing brochures, and pre and post surveys only.

Group Type ACTIVE_COMPARATOR

Control

Intervention Type BEHAVIORAL

Participants in the Control arm will receive CDC-designed COVID-19 testing brochures, and pre and post surveys only.
