The coronavirus (COVID-19) pandemic and attendant lockdown measures present serious threats to emotional well-being worldwide. Here, we examined the extent to which being outdoors (vs. indoors), the experience of loneliness, and screen-time are associated with emotional well-being during the COVID-19 pandemic using an experiencing sampling method. In April 2020, Austrian adults (N = 286, age M = 31.0 years) completed a 21-day experience sampling phase in which they reported their emotional well-being (i.e., happiness), whether they were indoors or outdoors, and loneliness at three random time-points each day, as well as their daily screen-time. Results indicated that being outdoors was associated with higher emotional well-being, whereas greater loneliness and greater daily screen-time were associated with poorer well-being. Additionally, the impact of loneliness on well-being was weaker when participants were outdoors than indoors. These results have health policy implications for the promotion of population well-being during pandemics.

冠状病毒 (COVID-19) 大流行和随之而来的封锁措施对全球的情绪健康构成了严重威胁。在这里，我们使用体验抽样方法检查了在 COVID-19 大流行期间户外（相对于室内）、孤独体验和屏幕时间与情绪健康的相关程度。2020 年 4 月，奥地利成年人（N  = 286，年龄M = 31.0 岁）完成了为期 21 天的体验抽样阶段，他们在每天三个随机时间点以及每天的三个随机时间点报告他们的情绪幸福感（即幸福感），无论他们是在室内还是室外，以及孤独感检测时间。结果表明，户外活动与更高的情绪幸福感相关，而更大的孤独感和更多的每日屏幕时间与更差的幸福感相关。此外，当参与者在户外时，孤独感对幸福感的影响比在室内时要弱。这些结果对在大流行期间促进人口福祉具有卫生政策意义。
