Abstract
There is growing interest in understanding the optimal design of food voucher programs to improve diet quality and support chronic disease self-management. We examined preferences for voucher program design among adults with low incomes who participated in a randomized trial. Participants preferred vouchers eligible for all foods over those restricted to fruits and vegetables (p=0.001), and a monthly over weekly redemption schedule (p=0.003). Preferences differed significantly by voucher assignment (p(interaction) for both<0.0001), with those assigned to the fruit and vegetable voucher more likely to prefer that voucher. Flexibility was identified as a key driver of preference.
