We constructed a preventive social behaviours (PSB) Index using survey questions that were aligned with WHO recommendations, and used linear regression to assess the impact of reported COVID-19 deaths (RCD), people's confidence of government handling of the pandemic (CGH) and government stringency (GS) in the United Kingdom (UK) over time on the PSB index. We used repeated, nationally representative, cross-sectional surveys in the UK over the course of 41 weeks from 1st April 2020 to January 28th, 2021, including a total of 38,092 participants. The PSB index was positively correlated with the logarithm of RCD (R: 0.881, < .001), CGH (R: 0.592, < .001) and GS (R: 0.785, < .001), but was not correlated with time (R: -0.118, = .485). A multivariate linear regression analysis suggests that the log of RCD (coefficient: 0.125, < .001), GS (coefficient: 0.010, = .019), and CGH (coefficient: 0.0.009, < .001) had a positive and significant impact on the PSB Index, while time did not affect it significantly. These findings suggest that people's behaviours could have been affected by multiple factors during the pandemic, with the number of COVID-19 deaths being the largest contributor towards an increase in protective behaviours in our model.
我们构建了一个预防社会行为（PSB）指数，使用与世界卫生组织建议一致的调查问题，并使用线性回归来评估报告的 COVID-19 死亡人数（RCD）、人们对政府处理大流行的信心（CGH）以及英国政府的严格程度（GS）随时间推移对 PSB 指数的影响。我们在 2020 年 4 月 1 日至 2021 年 1 月 28 日期间，在英国进行了 41 周的重复、全国代表性的横断面调查，共有 38092 名参与者。PSB 指数与 RCD 的对数呈正相关（R：0.881，<0.001）、CGH（R：0.592，<0.001）和 GS（R：0.785，<0.001），但与时间无关（R：-0.118，=0.485）。多元线性回归分析表明，RCD 的对数（系数：0.125，<0.001）、GS（系数：0.010，=0.019）和 CGH（系数：0.009，<0.001）对 PSB 指数有积极且显著的影响，而时间没有显著影响。这些发现表明，在大流行期间，人们的行为可能受到多种因素的影响，我们模型中 COVID-19 死亡人数的增加是导致保护行为增加的最大因素。
