“The conventional expectation was that depression and mental distress would dramatically increase as a result of the COVID-19 pandemic, and some initial research seemed to be consistent with that expectation,” said Ruhm, who partnered with lead author Ronald C. Kessler of Harvard and Kessler’s colleagues in the Harvard Medical School. “However, the data on which those conclusions were based might have problems, and so we wanted to see if these results would be verified when using better data.”
In order to get an early indication about how the pandemic was affecting people, a number of research groups conducted online surveys – among the better known being the CDC’s Household Pulse Survey, a poll started in April 2020 to track the effects of COVID-19 on U.S. residents.
When compared to previous government studies, such as phone surveys under the CDC’s Behavioral Risk Factor Surveillance System, a monthly state-based trend survey, Household Pulse seemed to chart dramatic increases in the severity of anxiety and depression. The findings were based on self-reported answers to questions that track with clinical standards.
But now that consistent data from the BRFSS phone interviewing has been analyzed comparing 2020 with corresponding periods in 2017, 2018 and 2019, it appears that there have been, at most, modest increases in the numbers of people suffering from anxiety and depression.
