Using MOST to Optimize an Intervention to Increase COVID-19 Testing for Frontline Essential Workers

Those assigned to receive Component A will engage in a MI single session lasting approximately 30-45 minutes. The overall goal of the session is to increase participants' motivation and readiness to test for COVID-19 in various circumstances.

"This intervention lasts 6 weeks. This component is grounded in principles of behavioral economics. Its main goal is to add interest and excitement to the goal of COVID-19 testing, serve as a reminder that COVID-19 testing is recommended in a number of scenarios, and nudge participants toward testing and creating a habit of serial screening and COVID-19 testing as needed. Participants first receive a brief orientation to the component (15 min.), and the participant will put the study phone number into his/her phone and a test TM and QQ will be sent. TMs and QQs are programmed into the Telerivet program and sent automatically. Twice a week participants will receive a TM with information about COVID and COVID-19 testing followed by a true/false question about that TM two days later, for which they earn 10 points for a correct answer, and 5 points for an incorrect answer. Participants earn modest prizes based on their points."

This component has two aspects: Participants are trained to educate their peers on core messages about the importance of COVID-19 testing that address social norms about COVID-19 testing and highlight COVID-19 testing as an altruistic act (15-20 min. training). Then, participants are given the opportunity to educate three peers who are Black and Latino/Hispanic frontline essential workers on the core messages. These peers contact the study directly and receive a brief assessment and referrals to testing, but are not enrolled in the study.

Component D is an adaptive intervention component that avoids unnecessary costs; it is only provided if needed. Level 1: Over a 2-3 week period, navigation includes a brief needs assessment and guidance to assist participants in prioritizing, accessing, and completing COVID-19 testing sequences in a timely fashion and resolving barriers such as transportation or the possible need to take off work if diagnosed with COVID-19. Level 2: 1 month after enrollment, participants will be contacted by phone. If they have not been tested, we will provide them with a BinaxNOW test kit which can be picked up or mailed to them.
