Abstract
Effective communication of when students should attend school, stay home, and return to school is a critical function of SARS-CoV-2 symptom screening mobile intervention. We developed two visualization aids (Alternative Aid A or B, or text only) to support families in determining when their child can return to school in-person. We obtained subjective feedback from 23 potential users. Seventy-four percent (17/23) of users rated Visual A as “Easy” or “Very Easy.” Visual B was rated by 57% (13/23) of users as “Not Easy/Not Hard.” Sixty-five percent (15/23) of users rated the text description as “Easy” or “Very Easy.” Visual A was reported as their first choice in determining when a child can return to school. A calculator may be preferential to users to determine return-to-school date. Future research should evaluate the impact of the decision support visual on user behavior with determining the return-to-school date.
