Development of an mHealth text message intervention to promote adherence to COVID-19 isolation recommendations for college students.

Background: Important tools in preventing the spread of COVID-19 include contract tracing and adherence to isolation guidelines after a positive diagnosis of COVID-19. This is especially relevant among college students who are often away from support systems at home, living in high-density housing, and may not experience serious symptoms from COVID-19 while still contagious. Objective: As text message-based interventions have been found effective in addressing health behaviors among young adults, we conducted formative research to explore how text messaging could support students in adhering to isolation guidelines. Participants: A convenience sample of college students (n = 104) at one university. Methods: An online survey gathered students' perceptions of helpful components to include in a text message-based intervention. Results: Students expressed interest in receiving text messages with support, encouragement, and resources during their time in isolation following a COVID-19 diagnosis. Conclusions: Based on the results, we developed a text message-based intervention designed to provide motivation, support, distraction, and information on resources.
