We report results from a pilot study examining the use of vouchers redeemable for retail items as incentives for smoking cessation during pregnancy and postpartum. Of 100 study-eligible women who were still smoking upon entering prenatal care, 58 were recruited from university-based and community obstetric practices to participate in a smoking cessation study. Participants were assigned to either contingent or noncontingent voucher conditions. Vouchers were available during pregnancy and for 12 weeks postpartum. In the contingent condition, vouchers were earned for biochemically verified smoking abstinence. In the noncontingent condition, vouchers were earned independent of smoking status. Abstinence monitoring and associated voucher delivery was conducted daily during the initial 5 days of the cessation effort, gradually decreased to every other week antepartum, increased to once weekly during the initial 4 weeks postpartum, and then decreased again to every other week for the remaining 8 weeks of the postpartum intervention period. Contingent vouchers increased 7-day point-prevalence abstinence at the end-of-pregnancy (37% vs. 9%) and 12-week postpartum (33% vs. 0%) assessments. That effect was sustained through the 24-week postpartum assessment (27% vs. 0%), which was 12 weeks after discontinuation of the voucher program. Total mean voucher earnings across antepartum and postpartum were 397 US dollars (SD=414 US dollars) and 313 US dollars (SD=142 dollars) in the contingent and noncontingent conditions, respectively. The magnitude of these treatment effects exceed levels typically observed with pregnant and recently postpartum smokers, and the maintenance of effects through 24 weeks postpartum extends the duration beyond those reported previously.
我们报告了一项试点研究的结果，该研究考察了可兑换零售商品的代金券作为孕期和产后戒烟激励措施的使用情况。在100名符合研究条件且在进入产前护理时仍在吸烟的女性中，有58名从大学附属医院和社区产科诊所招募而来，参与一项戒烟研究。参与者被分配到有条件或无条件代金券组。代金券在孕期及产后12周内可用。在有条件组中，只有经生化验证戒烟才能获得代金券。在无条件组中，无论吸烟状况如何均可获得代金券。在戒烟努力的最初5天，每天进行戒烟监测并发放相关代金券，产前逐渐减少至每隔一周发放一次，产后最初4周增加至每周发放一次，然后在产后干预期的剩余8周再次减少至每隔一周发放一次。有条件代金券使妊娠末期（37%对9%）和产后12周（33%对0%）的7天点患病率戒烟率提高。这种效果在产后24周评估时（27%对0%）仍持续存在，此时代金券计划已停止12周。产前和产后有条件组和无条件组的代金券平均总收入分别为397美元（标准差=414美元）和313美元（标准差=142美元）。这些治疗效果的幅度超过了通常在孕期和产后近期吸烟的人群中观察到的水平，并且效果持续到产后24周，其持续时间比之前报道的更长。
