Promoting Engagement and COVID-19 Testing for Health

Study Overview
=================
Brief Summary
-----------------
PEACH2 is a community-based study, targeting individuals affected by diabetes. Study participants will be randomized into the PEACH2 Intervention Arm or the Control Arm. The intervention lasts for 4 months and participants will be followed for 10 months in total.

Detailed Description
-----------------
This study leverages data collected during Project PEACH 1: Promoting Engagement and COVID-19 Testing for Health, a Rapid Acceleration of Diagnostics - Underserved Populations (RADx-UP) funded study to understand barriers to effective and equitable coronavirus disease 2019 (COVID-19) testing in high-risk and minority populations in Georgia that are affected by diabetes. PEACH 1 applied mixed-methods (quantitative, qualitative, geographic and spatial analysis) to gather evidence to describe COVID-19 epidemiology, locate regions and populations with low testing and vaccine uptake, and targeting key informant interviewing and monitoring social and news media, to identify barriers, motivators, and perceptions around COVID-19 as well as related behaviors among different populations and regions. Analysis of Project PEACH 1 data collected from key informants and community partners indicated gaps in capacity for and commitment to community testing when vaccines became available, and sites were pivoting to prioritize vaccinations even as they continued to provide COVID-19 testing. However, COVID-19 testing can be a key tool to address the pandemic, particularly in areas with low vaccination rates and high diabetes rates such as Georgia. People with diabetes, prediabetes, and obesity have elevated risk for COVID-19 infection and are more likely to suffer in-hospital complications. Further, Diabetes is 2.4 times more common in socioeconomically vulnerable and minority populations. Throughout the pandemic, counties with predominantly Black communities had a 6-fold COVID-19 death rate compared to those that are predominantly White. For these reasons, finding sustainable, easy to disseminate, and acceptable ways to increase and sustain COVID-19 testing is needed. Further, understanding the relationship between attitudes toward testing in situations of continued vaccine hesitancy and resistance and developing insights in how to address them in a dynamic pandemic situation will be fundamental to future pandemic response. COVID-19 testing, both home-based testing and clinic testing, must remain a key feature for diabetes management and prevention to reduce secondary complications associated with infection. Home-based testing may help people overcome barriers to testing (identifying where to get tested, scheduling and attending appointments, stigma). However, in order for it to be successful there is a need to understand the feasibility, acceptability, and sustainability of at-home testing as well as the perceived advantages and disadvantages of home-based testing compared to clinic-based testing among the high-risk population of individuals affected by or at risk for diabetes. This information can be used to create targeted behavioral nudges. Nudges are indirect suggestions and positive reinforcements designed to encourage certain choices. They may be a useful means of promoting acceptability and usage of COVID-19 testing as well as increasing an understanding of and acceptability of other key preventive behaviors like COVID-19 vaccination. Behavioral nudges have been shown to have a noticeable effect on health behaviors and study recruitment, however, research testing the application of behavioral nudges relating to behavior change around disease prevention in a pandemic situation is needed. Study participants will be randomized into the PEACH2 Intervention Arm or the Control Arm. At baseline, all participants will be asked to complete a baseline survey to collect demographic data, history of COVID-19, diabetes, and diabetes risk factors, views of COVID-19, COVID-19 preventive behaviors (including vaccination), and experiences with COVID-19 testing. Participants will be asked to report, using a simple text-based data reporting tool, any COVID-19 testing during the 10-month study. Participants will be followed up for 10 months after baseline, with additional survey data collection at 4 and 10 months (post-intervention and 6 months after intervention completion) to collect information on COVID-19 testing, prevention, and vaccine behaviors and views. In addition, Project PEACH2 Intervention participants will be sent weekly personalized behavioral nudges via mobile phone text message during the 4 month long intervention to encourage adherence to COVID-19 testing and preventive behaviors as well as share important tips for diabetes management, prevention or care. Nudges targeting testing behaviors will be delivered whereby participants who have not reported (1) having symptoms indicative of a possible infection with a viral disease and (2) a COVID-19 test in the past four weeks will receive a nudge to encourage COVID-19 testing. Other behavioral nudges will target other COVID-19 related preventive behaviors (e.g., staying home when sick, wear a mask, etc.) and diabetes management/prevention/care behaviors (e.g., increasing physical activity, improving diet, decreasing stress, etc). Nudge personalization targeting relationship with diabetes, age group, sex, vaccine and testing history, and race/ethnicity will be based on data collected in PEACH 1 as well as ongoing social media and data analysis in PEACH2.
