Project PEACH2 Intervention
In addition to a text-based reporting tool for reporting coronavirus disease 2019 (COVID-19) testing, participants randomized to the Project PEACH2 intervention were sent weekly behavioral nudges via mobile phone text message to encourage adherence to COVID-19 testing and preventive behaviors.
COVID-19 Test Reporting: Participants use a simple text-based data reporting tool which they are asked to use to report any COVID-19 testing during the 12-month long study.
Personalized Nudges via Text Messaging: Weekly behavioral nudges via mobile phone text messages, personalized to participants' diabetes status, race/ethnicity, age group, sex, and/or vaccine/testing history, are sent in weeks 1-16 of the intervention to encourage adherence to COVID-19 testing and preventive behaviors as well as other behaviors important for diabetes management, prevention, or care.

Control Group
Participants randomized to the control group receive access to the text-based COVID-19 reporting tool and receive weekly texts on diabetes prevention, management or care.
COVID-19 Test Reporting: Participants use a simple text-based data reporting tool which they are asked to use to report any COVID-19 testing during the 12-month long study.
Non-personalized Nudges via Text Messaging: Weekly behavioral nudges via mobile phone text messages are sent in weeks 1-16 of the intervention sharing tips lifestyle behaviors important for diabetes management and prevention (e.g., exercise, eating a healthy diet, etc.).
