In the pilot, which was conducted in Hampden County, Massachusetts, HIP participants received a 30% incentive added back to their benefit card when they purchased targeted fruits and vegetables in participating retailers. A randomly assigned control group received SNAP benefits as usual with no incentive.
On average HIP participant adults on SNAP consumed 0.23 cup-equivalents more in daily targeted fruits and vegetables -- a 25% increase -- compared to the non-HIP adults on SNAP.
HIP Participants Consumed 0.23 Cup-Equivalent
More Fruits and Vegetables per Day
The HIP Evaluation Study was led by Abt Associates, Inc., with participation from Westat and the Friedman School of Nutrition Science and Policy at Tufts University. Susan Bartlett from Abt was the project director. On behalf of the Friedman School, I was director of design for the evaluation study and a co-author of the final report.
The pilot represents the most ambitious effort so far to deliver a healthy eating incentive to SNAP participants right through the SNAP card (as opposed to a separate coupon) and in a full range of participating retailers (as opposed to farmers' markets alone). The results complement new work being done by Wholesome Wave and others to explore the potential of financial incentives.
The primary results were based on two post-implementation rounds of surveys of SNAP participants. Preliminary results, based just on the first post-implementation survey round, were published recently in the American Journal of Agricultural Economics (may be gated). The new full report released today has more information about a wide variety of food spending, shopping behavior, and food intake outcomes, and it analyzes the likely cost of extending such a healthy incentives program nationwide.
