To describe the design, implementation, and consumer response to a coupon-style intervention aimed to increase Supplemental Nutrition Assistance Program (SNAP) use at a farmers' market (FM) among Temporary Assistance for Needy Families (TANF) participants.
A quasi-experimental trial to evaluate redemption response to 2 coupon interventions; baseline surveys characterized coupon redeemers and non-redeemers.
Urban.
The TANF recipients were assigned to either a plain (n = 124) or targeted marketing coupon intervention (n = 130).
INTERVENTION(S): Both groups received 10 $2 coupons to double fruit and vegetable SNAP purchases at the FM. The targeted marketing group also received an oral presentation designed to reduce perceived barriers to FM use.
Coupon redemption.
The researchers used t tests and chi-square/Fisher exact tests to examine associations between redeemers and non-redeemers; logistic regression was used to adjust for the intervention.
No male and few female participants redeemed coupons (6.3%). Among women, those with knowledge of vegetable preparation were 3 times more likely to redeem coupons than were those with little or no knowledge (odds ratio = 3.77; 95% confidence interval, 1.03-13.77).
Stand-alone coupon incentive programs may not be a high-reach strategy for encouraging FM use among the population using TANF. Complementary strategies to build vegetable preparation knowledge and skills are needed.
描述一项优惠券式干预措施的设计、实施及消费者反应,该干预旨在增加临时援助家庭(TANF)参与者在农贸市场(FM)使用补充营养援助计划(SNAP)的情况。
一项准实验性试验,以评估对两种优惠券干预措施的兑换反应;基线调查对优惠券兑换者和未兑换者进行了特征描述。
城市。
TANF受助者被分为普通优惠券干预组(n = 124)或针对性营销优惠券干预组(n = 130)。
两组均获得10张2美元优惠券,用于在农贸市场双倍兑换SNAP购买的水果和蔬菜。针对性营销组还接受了一次口头宣传,旨在减少对使用农贸市场的感知障碍。
优惠券兑换情况。
研究人员使用t检验和卡方检验/费舍尔精确检验来检查兑换者和未兑换者之间的关联;使用逻辑回归对干预进行调整。
没有男性参与者兑换优惠券,只有少数女性参与者兑换了优惠券(6.3%)。在女性中,了解蔬菜烹饪方法的人兑换优惠券的可能性是几乎不了解或完全不了解的人的3倍(优势比 = 3.77;95%置信区间,1.03 - 13.77)。
独立的优惠券激励计划可能不是鼓励TANF人群使用农贸市场的有效策略。需要采取补充策略来培养蔬菜烹饪知识和技能。
