Fig. 2: Group means of trajectories of psychopathological symptoms, COVID-19-related rumination and stress-related growth.

Group means of trajectories of psychopathological symptoms (a), COVID-19-related rumination (b) and stress-related growth (c). Red and blue horizontal lines in panel (a) represent cutoff scores for the German version of the Brief Symptom Inventory [47], which were derived from a clinical sample [109], while no norm values were available for COVID-19-related rumination and stress-related growth. Percentages reflect proportions relative to the total sample of 1275 respondents.
