Evolution of preventive behaviour, perceived health risks, perceived social norms, trust in institutions, infections and government measures.
Evolution of preventive behaviour, perceived health risks, perceived social norms and trust in institutions (N = 10210 obs. of 2030 individuals), along with official numbers of daily infections and date of introduction or relaxation of government measures. Each line displays the weighted values of corresponding normalized additive indices. Whiskers indicate 95% confidence intervals. See Methods for detailed descriptions of these variables and S1 Appendix in S1 File for descriptive statistics (A1) and question wordings (C2).

Evolution of preventive behaviour by different tertiles of perceived health risks, perceived social norm and trust in institutions.
Evolution of preventive behaviour by different tertiles of perceived health risks, perceived social norm and trust in institutions (N = 10210 obs. of 2030 individuals). SN = Perceived social norms; TI = Trust in institutions. Whiskers indicate 95% confidence intervals. Levels of predictors (1st, 2nd, and 3rd tertile) are calculated using within wave tertiles, each containing one third of our observations per wave. Low, medium and high perceived risk levels are calculated using overall perceived risk tertiles. See Methods for detailed descriptions of these variables.

Linear prediction of preventive behaviour by perceived social norm conditional on the level of perceived health risks.
Linear prediction of preventive behaviour by perceived social norm conditional on the level of perceived health risks. Predictions based on estimates in model 3 in Table 1. Linear Fixed Effects model with wave as well as individual fixed effects. 95% confidence intervals (light blue areas) are calculated using two-way clustered standard errors for individuals and waves. The histogram represents the distribution of social norm perceptions in the sample. Dashed lines mark a +/- one within-individual SD from the mean.
