We also found that those experiencing clinically relevant depressive symptoms shortly before the pandemic showed a decrease in depressive symptoms, self-esteem and sleep duration between pre- and during- lockdown (interaction p = 0.047, p = 0.045 and p < 0.001, respectively) as compared to those who were not. However, we found evidence that mean sleep duration (in minutes) decreased significantly between during- and post- lockdown (− 12.16 95% CI − 18.39 to − 5.92 p < 0.001). For the sample as a whole, we found no evidence that depressive symptoms or self-esteem changed between pre-, during- and post-lockdown. In our sample of 252 participants, 48% ( n = 121) had clinically relevant depressive symptoms shortly before the pandemic. We used mixed models for repeated measures to estimate trajectories of depressive symptoms, self-esteem, and sleep duration. Self-reported questionnaire and passive data streams were analysed from participants who had joined the project prior to 1st December 2019 and had completed Patient Health and Self-esteem Questionnaires during the pandemic ( n = 252). This study is a secondary analysis of an on-going cohort study, RADAR-MDD project, a multi-centre study examining the use of remote measurement technology (RMT) in monitoring MDD. This study seeks to assess the impact of the 1st lockdown – pre-, during and post – in adults with a recent history of MDD across multiple centres. Those diagnosed with major depressive disorder (MDD) may be negatively impacted by the global pandemic due to social isolation, feelings of loneliness or lack of access to care. In fact, according to the study, the mandates had no detectable effect on either COVID-19 cases or deaths - and only small effects on the economy.The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes a clinical illness Covid-19, has had a major impact on mental health globally. “There’s a second group of people who were not going to change their behavior no matter what, without the policy or with the policy.” “There was one group of people who were already changing their behavior already sheltering in place, without any need for an order from the government to do so,” Berry said. Smartphone location data shows that Americans only decreased their movements, on average, by less than 1% during the stay-at-home mandates.

It turns out Americans aren’t good at following rules. In terms of reducing the spread of the disease and deaths from the disease, and also whether they’re making a difference on the cost side, in terms of reducing economic activity,” said Christopher Berry, a public policy professor at the University of Chicago. “We wanted to find out is whether the shelter in place orders were making a difference.


Previous studies have claimed shelter-in-place orders saved thousands of lives, but one group of researchers at the University of Chicago put this theory to the test.
