From the conclusion:
A minority of funds went unused. Possible reasons for this gap include that tokens were lost, misplaced, or reserved for a future visit that did not occur. Regardless, a loss in purchasing power negatively affects the financial benefits provided by the incentive program, and means that SNAP participants have fewer funds to mitigate food insecurity. Future work should strive to better understand this problem in various communities and test innovative solutions to increase SNAP redemption rates. Additionally, further exploration will be helpful to determine what maximum amount of SNAP benefits
matched maximizes participation by SNAP customers. To better understand the health impacts on individuals who use SNAP incentives to purchase fresh produce, future research also should explore changes in consumption and other health behavior. Finally, examining the relationship between various implementation strategies and reported changes in consumers, vendors, and markets will help better identify promising practices for effective incentive programs. The cluster evaluation documented program innovations; influences of incentive programs on consumers, vendors, and markets; and lessons learned to inform a fragmented field of practice. The cluster program organizations are poised and ready to share what they are learning about effective program management, marketing, funding, capacity building, sustainability strategies, and achieving desired outcomes with fellow practitioners. After sharing program experiences, program implementation, and outcome data, and advancing ideas on how best to advance and implement solutions to food system issues of common concern through this cluster evaluation, the programs are exploring plans to launch an online “Learning Community” that would bring more program coherence to the field of practice and increase the field’s capacity to be more impactful.
