In response to the COVID-19 pandemic, most communities in the United States imposed stay-at-home orders to mitigate the spread of the novel coronavirus, potentially leading to chronic social isolation. During the third week of shelter-in-place guidelines, 1,013 U.S. adults completed the UCLA Loneliness Scale-3 and Public Health Questionnaire (PHQ-9). Loneliness was elevated, with 43% of respondents scoring above published cutoffs, and was strongly associated with greater depression and suicidal ideation. Loneliness is a critical public health concern that must be considered during the social isolation efforts to combat the pandemic.

孤独：在COVID-19时代对精神健康的关注。

为了应对COVID-19大流行，美国大多数社区都实施了在家待命的命令，以减轻新型冠状病毒的传播，从而可能导致长期的社会隔离。在就地避难所指南的第三周，有1,013名美国成年人完成了UCLA孤独感量表3和公共卫生问卷（PHQ-9）。孤独感有所提高，有43％的受访者的得分高于已公布的临界值，并且与更大的抑郁和自杀意念密切相关。孤独感是关乎公共卫生的关键问题，在社会隔离与流行病作斗争的过程中必须予以考虑。
