Application of Economics & Social psychology to improve Opioid Prescribing Safety (AESOPS) Trial

摘要 SARS-CoV-2病毒的迅速传播极大地影响了服务不足的人群。这 该项目旨在了解COVID-19检测的社会和行为决定因素， 这一群体中的子群体之间的差异。与最大的联邦合格的 在美国的健康中心，我们将收集调查数据，并进行随机 对2，160人（540个家庭）进行实验，以评估基于风险的 宣传和激励措施，促进SARS-CoV-2抗体的重复检测。成2 × 2 （消息x激励）析因实验，参与者完成一套全面的 社会和行为调查，以确定对检测承诺的决定因素。然后将它们 按调查中确定的分层随机分配，以接受个性化消息宣传 反复测试。信息传递将侧重于（1a）他们的家庭风险或（1b）他们的 COVID-19的个人风险。他们也被随机分配到一个激励条件， （2a）确保不会失去初始测试的基线奖励，或（2b）使他们进入一个 如果他们完成两项测试，就有很小的机会赢得100美元的彩票。保险和 彩票条件具有相同的激励成本。我们之前在类似人群中的研究 表明，坚持计划的健康行为是更高的保险为基础的 奖励比同等价值的现金支付。这个实验比较了基于保险的 彩票激励措施已被证明是有效的，在多种情况下。最后， 我们评估了健康的社会和行为决定因素是否导致异质性治疗， 影响，可以告知定制的激励产品在未来的计划，专门用于 在得不到充分服务的人群中增加检测或疫苗接种。

Abstract The rapid spread of the SARS-CoV-2 virus has greatly impacted underserved populations. This project aims to understand social and behavioral determinants of COVID-19 testing and variations within sub-groups of this population. In partnership with the largest federally qualified health center in the United States, we will collect survey data and conduct a randomized experiment on 2,160 individuals (540 families) to evaluate the effectiveness of risk-based messaging and incentives that promote repeated testing for SARS-CoV-2 antibodies. In a 2 x 2 (Messaging x Incentive) factorial experiment, participants complete a comprehensive set of social and behavioral surveys to identify determinants of commitment to testing. They are then randomized by strata identified in the survey to receive personalized messaging promoting repeated testing. Messaging will focus upon either (1a) their household risk or (1b) their personal risk of COVID-19. They are also randomly assigned to either an incentive condition that (2a) insures against losing baseline rewards for initial testing, or (2b) that enters them into a lottery with a small chance to win $100 if they complete both tests. Both the insurance and lottery conditions carry the same incentive costs. Our previous work in similar populations demonstrated that adherence to planned health behaviors is higher with insurance-based incentives than cash payments of equal value. This experiment compares insurance-based incentives to lottery incentives that have been shown to be effective in multiple contexts. Finally, we evaluate if social and behavioral determinants of health result in heterogeneous treatment effects that can inform customization of incentive offerings in future programs devoted to increasing uptake of testing or vaccinations among underserved populations.
