Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

University of Wyoming (UW) and Wyoming Food for Thought Project (WFFTP) propose to collaboratively develop, pilot, and evaluate a trial on the impact of market vouchers on food security and fruit and vegetable (F\&V) consumption. We will (a) provide farmers market vouchers to families who are enrolled in WIC, SNAP, or free or reduced lunch and/or have incomes ≤185% of poverty line; (b) assess impacts of these supports on household food security and F\&V consumption; and (c) test feasibility and impacts of vouchers valid only for F\&V vs. for any foods that can be purchased with SNAP.

To test the feasibility and preliminary impacts of this approach, we will enroll 30 individuals/households in this study, randomizing 10 to each of the 2 intervention arms and 10 to waitlist control. Qualifying individuals and families will be able to enroll in the study at the WFFTP Tuesday afternoon/evening market on July 30th, 2019. They will be randomized upon enrollment to one of three conditions: receiving $20 in vouchers at each of up to 4 markets ($80 total) that are good for F\&V only, receiving $20 vouchers at each of up to 4 markets that are good for any foods that SNAP/EBT benefits can be used for; or delayed intervention/waitlist control (who, at the final data gathering, will receive 5 x $20 in vouchers good at the WFFTP 2019 and 2020 markets).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

To be eligible for the intervention, a participant must be an adult aged ≥18 years old whose household is enrolled in or eligible for SNAP, free or reduced school lunch program, and/or WIC (i.e., incomes of ≤185% of poverty for household size). UW staff wills screen for eligibility by verifying a participant has an EBT card. If no card is available, participants will be asked to self-report household income and size and UW staff will use the Federal Poverty Level chart to determine the individual's eligibility. They must also self-identify as living in Casper, Wyoming. They must come in person to the market on July 30th, 2019, to enroll.
