Covid-19, mental health, and the environment in which we live

People’s wellbeing is intimately linked to their environment including the place in which they live. This series will build towards examining some of the linkages that have been exposed during the Covid-19 pandemic and some of these findings will likely read across to the journals broader special series on Covid-19 interactions with our environment.

The UCL-Penn Global COVID Study launched in April 2020 is a 12-month longitudinal study of the impact of Covid-19 on social trust, mental health, and physical health. In collaboration with 6 institutions from Italy, Singapore, USA, China, and the UK,  the study looks at the short- and long-term effects of Covid-19 on individual’s mental health and social relationships with others.

Held online between the 2nd June and 28th July 2021, the study group ran five online webinars (one for each article) discussing the lessons learned and to speak on the policy relevance and implications of the study, with invited policy makers and other subject experts. The recorded comments from these discussions focusing on the policy relevance and implications of each academic article will be published as a ‘discussant’ article alongside the academic article.
