确定采用NHS COVID-19接触者追踪应用程序并持续使用的关键个人层面(人口统计学、态度、流动性)和背景(COVID-19病例数、流动性限制等级、市区)决定因素。2020年7月(背景调查)、2020年11月(应用程序采用的第一次测量)和2021年3月(应用程序的持续使用和新采用者)在英格兰进行的三波小组调查与官方数据相关联。N=2500名居住在英格兰的成年人,代表英格兰人口的区域分布、年龄和性别(2011年人口普查)。重复测量自我报告的应用程序使用情况。多水平逻辑回归将一系列个人水平(来自调查)和背景(来自关联数据)决定因素与应用程序使用联系起来。我们观察到,到2021年3月,初始应用程序的使用率为41%,95%CI(0.39%至0.43%),退出率为12%,95%CI(0.10%至0.14%)。我们还发现,在第2波中,7%的非用户在第3波中成为新的采用者,95% CI(0.05%至0.08%)。最初使用(或未能使用)该应用程序与社会规范、隐私问题和有关第三方数据访问的错误信息有关,居住在邮政区的人不太可能使用该应用程序,因为他们认为缺乏透明的有效性证据与放弃使用有关。此外,那些信任政府的人更有可能在第三波收养中成为新的收养者。接触者追踪应用程序的成功应用应在英国政府应对危机的更广泛背景下进行评估。对政府的信任是第三波应用程序采用的关键,而持续使用则与对透明证据的看法有关。提供明确的信息,以解决隐私问题可以增加吸收,但是,在少数民族参与者之间的持续使用的差异需要进一步调查。
To identify the key individual-level (demographics, attitudes, mobility) and contextual (COVID-19 case numbers, tiers of mobility restrictions, urban districts) determinants of adopting the NHS COVID-19 contact tracing app and continued use overtime. A three-wave panel survey conducted in England in July 2020 (background survey), November 2020 (first measure of app adoption) and March 2021 (continued use of app and new adopters) linked with official data. N=2500 adults living in England, representative of England’s population in terms of regional distribution, age and gender (2011 census). Repeated measures of self-reported app usage. Multilevel logistic regression linking a range of individual level (from survey) and contextual (from linked data) determinants to app usage. We observe initial app uptake at 41%, 95% CI (0.39% to 0.43%), and a 12% drop-out rate by March 2021, 95% CI (0.10% to 0.14%). We also found that 7% of nonusers as of wave 2 became new adopters by wave 3, 95% CI (0.05% to 0.08%). Initial uptake (or failure to use) of the app associated with social norms, privacy concerns and misinformation about third-party data access, with those living in postal districts with restrictions on mobility less likely to use the app. Perceived lack of transparent evidence of effectiveness was associated with drop-out of use. In addition, those who trusted the government were more likely to adopt in wave 3 as new adopters. Successful uptake of the contact tracing app should be evaluated within the wider context of the UK Government’s response to the crisis. Trust in government is key to adoption of the app in wave 3 while continued use is linked to perceptions of transparent evidence. Providing clear information to address privacy concerns could increase uptake, however, the disparities in continued use among ethnic minority participants needs further investigation.
