CHRONIC DISEASES
We measured willingness to bring medicines with 4 survey questions on 5-point Likert scales (Table S1 in We aggregated the responses and used the Wilcoxon rank sum test and mean score test to assess the impact of different nudging interventions on willingness scores. We further assessed if demographics (age, household income, education, and race) and chronic medical conditions influenced the impact of nudging.We also combined several demographic variables for ease of analysis. Age (in years) was combined into 3 groups: younger than 35 years, between 35 and 49 years, and equal to and older than 50 years. Education level was combined into 3 groups: less than a bachelor’s degree, bachelor’s degree, and a graduate degree. Race was combined into 2 groups: White and non-White. Income (in US $) was combined into 3 groups: less than US $40,000, US $40,000-$80,000, and greater than US $80,000. The number of chronic diseases was combined into 2 groups: 0 and more than 0.
