This study by Winkler et al explored data from three cross-sectional datasets to compare mental disorder prevalence in the second wave of the COVID-19 pandemic with the first wave and baseline. The cross-sectional studies included results from Czech adults collected in November 2017 and May 2020, while data for the present study was collected in November 2020. Participants were contacted via phone or email. Results of the study indicated that the proportion of individuals with at least one mental disorder during the second wave of the pandemic (November 2020) was close to 13 percentage points higher than the pre-pandemic baseline (November 2017). The proportion of participants that scored positive for affective disorders tripled and anxiety disorders nearly doubled, from November 2017 to 2020. Alcohol use disorders did not significantly change within this time frame, as well as between the first and second wave of the pandemic. Groups that experienced the highest prevalence of mental disorders consisted of those who lost their jobs in the last 6 months, students, those receiving disability pensions, and those on forced leave.
