目标确定采用 NHS COVID-19 接触者追踪应用程序并继续加班使用的关键个人层面（人口统计、态度、流动性）和背景（COVID-19 病例数、流动性限制级别、城市地区）决定因素。设计和设置于 2020 年 7 月（背景调查）、2020 年 11 月（应用程序采用的第一次衡量）和 3 月在英格兰进行的三波小组调查 2021 年（应用程序的持续使用和新采用者）与官方数据相关联。参与者 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）。主要结果重复测量自我报告的应用程序使用情况。分析方法将一系列个人水平（来自调查）和情境（来自关联数据）决定因素与应用程序联系起来的多级逻辑回归 结果我们观察到应用程序的初始使用率为 41%，95% CI（0.39% 至 0.43%），到 2021 年 3 月，退出率为 12%，95% CI（0.10% 至 0.14%）。我们还发现，从第 2 波开始，7% 的非用户到第 3 波成为新的采用者，95% CI（0.05% 至 0.08%）。该应用程序的最初使用（或未能使用）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，居住在行动不便的邮政区的人不太可能使用该应用程序。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中作为新采用者采用。 结论 应在英国政府应对危机的更广泛背景下评估接触者追踪应用程序的成功采用。对政府的信任是第三波应用程序采用的关键，而持续使用则与透明证据的看法相关。提供明确的信息来解决隐私问题可能会增加使用率，但是，少数族裔参与者之间持续使用的差异需要进一步调查。
ObjectiveTo 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.Design and settingA 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.ParticipantsN=2500 adults living in England, representative of England’s population in terms of regional distribution, age and gender (2011 census).Primary outcomeRepeated measures of self-reported app usage.Analytical approachMultilevel logistic regression linking a range of individual level (from survey) and contextual (from linked data) determinants to app usage.ResultsWe 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.ConclusionsSuccessful 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.
