Culturally-Targeted COVID-19 Communication and SARS-CoV-2 Antibody Testing Evaluation and Uptake

Study Overview
=================
Brief Summary
-----------------
This disparities-focused study seeks to evaluate communication strategies for better encouraging understanding and uptake of salivary SARS-CoV-2 antibody testing among African Americans residing in Flint, Michigan. This iteration will consider individuals recruited from the Flint Registry and assess willingness to participate in a drive-up saliva sample collection taking place at a central location in Flint, Michigan.

Detailed Description
-----------------
African Americans develop and die from SARS-CoV-2 infection more than any other racial group in the United States, including in majority African American cities such as Flint, Michigan. Addressing these disparities may be aided by SARS-CoV-2 antibody testing. However, African Americans may be reluctant to partake in conventional antibody testing programs due to medical mistrust and experiences with racism. This study seeks to evaluate communication strategies for better encouraging understanding and uptake of salivary SARS-CoV-2 antibody testing. The central hypothesis is that African-Americans will be more receptive to antibody testing when benefits and limitations are communicated in a culturally effective manner. Our clinical trial aims are to 1) develop and compare effects of a general versus culturally-targeted video about antibody testing on African American and White Flint residents' antibody testing attitudes and uptake; 2) identify and compare effects of a general versus culturally-targeted video on activation of medical mistrust and racism-related cognition among African Americans when considering antibody testing. In collaboration with clinical and community partners, we have prepared and will evaluate general and culturally-targeted video tutorials about SARS-CoV-2 antibody testing. These brief videos will be distributed to the Flint community through the Flint Registry - a highly visible local health resource exchange. We will furnish an opportunity to engage salivary antibody screening and measure willingness to participate. In this study iteration, we will consider willingness to participate in a drive-up saliva sample collection that is taking place at a central location in Flint, Michigan.

Design Details

Primary Purpose: Screening
Allocation: Randomized
Intervention Model: Single Group Assignment
Interventional Model Description: Design is partial factorial. All white participants and half of African American participants will receive general video education/messaging. Half of African American participants will be assigned to an intervention condition that includes culturally-targeted information about SARS-CoV-2 antibody testing.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: White Flint Registry: General<br>White participants receive general consumption video information about SARS-CoV-2 antibody testing. | Behavioral: General SARS-CoV-2 Communication<br>* SARS-CoV-2 video tutorial is for general consumption and does not include culturally targeted information<br>|
| Active Comparator: African American Registry: General<br>African American participants receive general consumption video information about SARS-CoV-2 antibody testing. | Behavioral: General SARS-CoV-2 Communication<br>* SARS-CoV-2 video tutorial is for general consumption and does not include culturally targeted information<br>|
| Experimental: African American Registry: Culturally Targeted<br>African American participants receive culturally targeted video information about SARS-CoV-2 antibody testing. | Behavioral: Culturally Targeted SARS-CoV-2 Communication<br>* SARS-CoV-2 video tutorial includes a one minute video based messaging adjunct meant to enact a culturally targeted framing of health information presented to African Americans.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Salivary Kit Request | Does participant request to receive a salivary kit from the study team? (yes-no) | up to 2 weeks | 
| Salivary Kit Completion | Do participants who request salivary kits use/return them? (yes-no) | up to 8 weeks | 
| Theory of Planned Behavior Antibody Testing Outcomes | Self-report measures of antibody testing attitudes, norms, perceived control, intentions to be screened are each adapted from published research (Lucas et al., 2021). These items are constructed following recommended procedures to ensure construct validity and adequate behavioral specificity (Fishbein & Ajzen, 2011). All items use Likert-type scales that range from 1 (strongly agree) to 7 (strongly disagree). | collected immediately, up to 1 hour | 
| Anticipatory Racism | Adapted from published research (Lucas et al., 2021), all participants respond to questions that asked whether they believe racism would impact the benefits they could experience from obtaining antibody testing. Participants will then respond to three questions that ask, In some way, my obtaining CRC screening would be impacted by racism, Racism would undermine the value of CRC screening for me. and Racism would negatively impact the accuracy of my CRC screening. Responses are collected using a 7-point Likert-type scale that ranged from 1 (strongly agree) to 7 (strongly disagree). | collected immediately, up to 1 hour |
