这项研究的目的是衡量一项试点干预措施的初步效果，该措施以行为经济学为基础，增加了双重保护的坚持（同时使用有效的现代避孕方法和屏障方法，如避孕套），以防止艾滋病毒、其他性传播感染和意外怀孕。2015年至2016年期间，在南非开普敦寻求堕胎后护理的100名年龄在18 - 40岁之间的妇女被招募参加Empower Nudge，这是一项随机对照试验，旨在测试旨在增加双重保护的彩票激励干预措施。基线时，参与者的平均年龄为27岁;其中82%来自南非; 58%自认为是非洲黑人;平均完成教育时间为11.7年。三个月后，分配彩票干预与返回研究访问的可能性更高相关（OR：6.0; 95%CI：2.45 - 14.7，p <0.01），安全套使用率较高（OR：4.5; 95%CI：1.43至14.1; p <0.05），以及更高的双重保护使用率（OR：3.16; 95%CI：1.01至9.9; p <0.05）。只有60%的研究人群在三个月后返回，只有38%在六个月后返回。接受堕胎后护理的妇女是一个被忽视的群体，迫切需要预防艾滋病毒和怀孕。双重保护是对这一群体至关重要的战略。彩票为基础的行为经济学战略可能会提供可能的方法，以增加双重保护使用在这一人群中。需要进一步研究更大的样本，更长的暴露时间，更多的网站，以建立充分的权力效力的彩票激励双重保护;使用客观验证的监测。
The objective of this study is to measure the preliminary efficacy of a pilot intervention, grounded in behavioural economics, increasing adherence of dual protection (simultaneous use of effective modern contraception and a barrier method, such as a condom) to protect against HIV, other sexually transmitted infections, and unintended pregnancy. Between 2015 and 2016, 100 women aged 18–40 years, seeking post-abortion care in Cape Town, South Africa were recruited to Empower Nudge, a randomised controlled trial to test a lottery incentive intervention designed to increase dual protection. At baseline, the mean age of participants was 27 years; 82% of them were from South Africa; 58% self-identified as Black African; average education completed was 11.7 years. At three months, assignment to the lottery intervention was associated with higher odds of returning for study visits (OR: 6.0; 95%CI: 2.45 to 14.7, p < 0.01), higher condom use (OR: 4.5; 95%CI: 1.43 to 14.1; p < 0.05), and higher use of dual protection (OR: 3.16; 95%CI: 1.01 to 9.9; p < 0.05). Only 60% of the study population returned after three months and only 38% returned after six months. Women who receive post-abortion care represent a neglected population with an urgent need for HIV and pregnancy prevention. Dual protection is a critically important strategy for this population. Lottery-based behavioural economics strategies may offer possible ways to increase dual protection use in this population. Further research with larger samples, longer exposure time, and more sites is needed to establish fully powered efficacy of lottery incentives for dual protection; using objective verification for monitoring.
