Review of WIC Food Packages: Proposed Framework for Revisions: Interim Report (2016)
Chapter: Appendix G: Literature Findings on Barriers and Incentives to WIC Participation and Redemption
TABLE G-1 Literature Findings on Barriers and Incentives to WIC Participation and Redemption
| Article | Barriers | Incentives/Strategies |
|---|---|---|
| Bertmann et al., 2014 |
Negative interactions in stores: annoyance or anger expressed by cashier or other shoppers Confusion over WIC rules: fluctuation in enforcement of redemption rules store to store and week to week Cashiers lack training: participants have to explain the rules Feeling of embarrassment when using CVV |
Find strategic choice of times and locations at which to shop Choose particular cashiers Pool CVV (using multiple vouchers at once) |
| Christie et al., 2006 |
Long duration of appointment wait time Dissatisfaction with customer service Dissatisfaction with the physical environment |
Decrease wait times by extending clinic hours and/or changing clinic flow High level of satisfaction with WIC personnel |
| Gleason and Pooler, 2011 |
Underutilization of infant food benefits |
Issue a CVV for F/V for caregivers who prefer preparing own infant foods Implement targeted nutrition education to subpopulations with high non-use of food instruments |
| Gleason et al., 2011 |
Maintaining food freshness (small WIC vendors) Availability of products in allowable form (e.g., bread in approved size) |
Continue and expand vendor training Continue to engage food suppliers Continue nutrition education of participants Use state WIC data for internal program management, policy making, ongoing monitoring Examine effect of minimum stocking requirements |
| Article | Barriers | Incentives/Strategies |
|---|---|---|
| Gleason et al., 2014 | Participants: | Participants: |
|
Gaps in knowledge (determining the amount of F/V with CVV) Incorrect information provided by cashier Limited selection of some WIC foods at local vendors and poor-quality produce Lack of transportation (e.g., tribe located 30 minutes from a store) Vendors: Delivery of spoiled items Difficulty anticipating demand and maintaining adequate supply of some WIC foods Challenges in serving participants who lack knowledge Challenges in communicating with local WIC agency |
Use more than one check at a time when transportation is an issue Vendors: Adopt practices that will make it easier for participants to shop WIC Staff: Use open-ended question and probing to encourage discussion with participants Expand nutrition education opportunities Inform participants of local vendors Local WIC Directors: Establish open lines of communication with vendors Increase cross-program collaboration State WIC Agencies: Offer additional training opportunities to staff Expand allowable WIC foods to include frozen and canned vegetables Develop a formalized local vendor liaison (LVL) program (California example: LVL makes visits) |
|
| Najjar, 2013 |
Food package policies (e.g., container size) Negative grocery store experiences and personal misunderstanding and embarrassment |
Helpful vendors Vendor and participant understanding about the use of CVV and other WIC benefits |
| Article | Barriers | Incentives/Strategies |
|---|---|---|
| Phillips et al., 2014 |
Certain individual WIC foods have low rates of full redemption Could not use certain foods (i.e., received too much) Participants or their children disliked the food or did not know how to prepare them Regardless of ethnicity, full redemption of WIC benefits is low |
Implement targeted educational efforts to promote full utilization of WIC benefits Tailor nutrition education to include foods that are commonly underused and focus on culturally relevant approaches to incorporating these foods into meals and snacks |
| USDA/ERS, 2010b |
Program requires too much effort, or scheduling, or transportation problems |
|
| USDA/ERS, 2013 |
Improved national economic conditions generally reduce participation rates for WIC and other national assistance programs |
Poorer economic conditions and unemployment rates tend to improve participation rates when the program is fully funded |
NOTE: CVV = cash value voucher; F/V = fruits and vegetables; LVL = local vendor liaison; SSI = Supplemental Security Income.

NOTES: Data presented as odds ratio (95% confidence interval); an odds ratio of 1.0 for this contrast indicates that the post-policy change from 2009 to 2010 was greater than the pre-policy change from 2008 to 2009; NE = odds ratio not estimated due to lack of variability in outcome by year. FV = fruits and vegetables.
a P < 0.05.
