Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

1277

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Wedge 1
The earliest group to implement the IMPROVE intervention ( in 4-9 study months). Clusters assigned to this sequence remained in the control condition for 3 months, received the intervention for 6 months, and completed follow-up assessments for 3 months.
Behavioral: IMPROVE
IMPROVE is a CBHN-led intervention. The study team delivered comprehensive training to CHNs to let them be well-prepared for intervention delivery. CHNs lead an in-person start-up group education session that consists of 4 modules: 1) a 6-minutes video of a health care provider delivering information on COVID-19 to help participants better understand the disease; 2) using educational slides, CHNs discuss the importance of COVID-19 testing and mitigation adherence; 3) CHNs conduct live demonstration of how to use rapid COVID-19 self-test kit correctly and distribute two COVID-19 self-testing kits to each participant. 4) CHNs guide interactive discussions with participants to enable them to reflect and reinforce what they learned. In addition, CHNs will help participants identify their navigation needs in reducing hesitancy of self-testing and mitigation practices. CHNs will also schedule check-in calls with participants.
Experimental: Wedge 2
Following the wedge 1 group, the wedge 2 group started the intervention in the study months 7-12. Clusters assigned to this sequence remained in the control condition for 6 months, received the intervention for 6 months, and completed follow-up assessments for 3 months.

Experimental: Wedge 3
The wedge 3 group started the intervention in the study months 10-15. Clusters assigned to this sequence remained in the control condition for 9 months, received the intervention for 6 months, and completed follow-up assessments for 3 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Lifetime Rate of COVID-19 Home Self-Testing Kit Use
Time Frame: baseline, 1-month follow up, and 3-month follow up
Lifetime use defined as self-report of ever using a COVID-19 rapid antigen home self-test kit at least once. Baseline was collected before IMPROVE implementation for all participants. The 1-month and 3-month follow-up assessments were collected after participants received the IMPROVE intervention, according to their wedge rollout schedule. Cleaned dataset with corrected data collection dates was used to update the results.
