The contagiousness and deadliness of COVID-19 have necessitated drastic social management to halt transmission. The immediate effects of a nationwide lockdown were investigated by comparing matched samples of New Zealanders assessed before (Nprelockdown = 1,003) and during the first 18 days of lockdown (Nlockdown = 1,003). Two categories of outcomes were examined: (a) institutional trust and attitudes toward the nation and government and (b) health and well-being. Applying propensity score matching to approximate the conditions of a randomized controlled experiment, the study found that people in the pandemic/lockdown group reported higher trust in science, politicians, and police, higher levels of patriotism, and higher rates of mental distress compared to people in the prelockdown prepandemic group. Results were confirmed in within-subjects analyses. The study highlights social connectedness, resilience, and vulnerability in the face of adversity and has applied implications for how countries face this global challenge.

COVID-19 大流行和全国封锁对信任、对政府的态度和福祉的影响。

COVID-19 的传染性和致命性使得必须采取严厉的社会管理来阻止传播。通过比较之前（Nprelockdown = 1,003）和锁定前18天（Nlockdown = 1,003）评估的新西兰人的匹配样本，研究了全国封锁的直接影响。研究了两类结果：(a) 机构对国家和政府的信任和态度，以及 (b) 健康和福祉。该研究应用倾向评分匹配来近似随机对照实验的条件，发现与人类相比，大流行/封锁组中的人对科学、政治家和警察的信任度更高，爱国主义水平更高，精神困扰的发生率也更高在封锁前的大流行病组中。结果在受试者内分析中得到证实。该研究强调了面对逆境时的社会联系、复原力和脆弱性，并对各国如何应对这一全球挑战产生了影响。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
