Munzert等人将移动的追踪数据和一项调查实验相结合，发现德国的联系人追踪应用程序在社交距离较短的人群中使用不足;然而，即使是小额现金奖励也会增加该群体的应用程序使用率。数字联系人追踪应用程序已在全球范围内推出，作为遏制COVID-19大流行的工具。然而，隐私的设计阻碍了这些工具的评估和部署基于证据的干预措施，以刺激吸收。我们将联合收割机在线小组调查与移动的跟踪数据相结合，以衡量德国官方接触者追踪应用程序的实际使用情况，并发现患有严重疾病风险增加的受访者使用率较高，但接触COVID-19风险增加的受访者使用率较低。使用随机干预，我们表明，信息和激励性的视频信息摄取的影响非常有限。然而，第二次干预的结果表明，即使是很小的金钱激励也可以大大提高使用率，并有助于使数字联系人追踪成为更有效的工具。
Combining mobile tracking data and a survey experiment, Munzert et al. show that Germany's contact tracing app is underused by those who socially distance less; however, even small cash incentives increased app uptake in the cohort.Digital contact tracing apps have been introduced globally as an instrument to contain the COVID-19 pandemic. Yet, privacy by design impedes both the evaluation of these tools and the deployment of evidence-based interventions to stimulate uptake. We combine an online panel survey with mobile tracking data to measure the actual usage of Germany's official contact tracing app and reveal higher uptake rates among respondents with an increased risk of severe illness, but lower rates among those with a heightened risk of exposure to COVID-19. Using a randomized intervention, we show that informative and motivational video messages have very limited effect on uptake. However, findings from a second intervention suggest that even small monetary incentives can strongly increase uptake and help make digital contact tracing a more effective tool.
