Half of them had a college or university diploma (54.3%), 39.9% had finished an apprenticeship, and 5.8% had no professional qualification. Most (69.3%) were married or in a relationship. Previous treatment for mental illness was reported by 29.9%; this is similar to the general epidemiology of mental disorders, which is constantly at about 30% [8] . It was reported by 2% of the participants that they had had a coronavirus infection and 80% said that they experienced relevant burdens during the pandemic. A high degree of embitterment (score ≥2.5 on the PTED scale [7] ; range 0-4) occurred in 16% of the sample. There were more people with embitterment (E: 9.5% of the total sample) than with embitterment and mental illness (EM: 6.17%); 60.87% reported no mental illness and no embitterment (NN) and 23.4% had mental illness but no embitterment (M). Embitterment was only weakly correlated with unspecific mental well-being (r = -0.258**). The embittered individuals reported a higher number of social and economic burdens than those without embitterment (e.g., job loss; E: 6%, EM: 12% vs. NN: 3%, M: 6%). The occurrence of embitterment of 16% during the pandemic is quite a high rate in comparison with 3% in Muschalla pre-pandemic times in the same region [9] . When looking into the literature, we found that embitterment has already been brought into the discussion in the context of the coronavirus pandemic [10] , and also that increased rates of embitterment of up to 15-45% may occur in contexts of critical life events [1] . Our research reports the first empirical data on embitterment occurring concurrently with events happening during the COVID-19 pandemic. One possible reason for this increased rate of embitterment is that critical events and injustices may have happened more often than usual during the pandemic, or else that people have perceived the ongoing and fast-changing conditions during the pandemic with increasing anger. Embitterment is one of the few mental health conditions that occurs in an event-related manner [2] . It can be triggered in healthy persons by events of injustice [2] . Embitterment is distinguishable from general mental disorders. The economic and social consequences of pandemic management should be carefully recognized and prevented by policy.
