1 For continuous variables we report the arithmetic mean. For categorical variables (e.g., sex), we report the percentage of respondents in that category. 2 For continuous variables only, we report the standard deviation. 3 For composite variables, we provide a suitable indicator of reliability: Pearson’s r for variables made up of two items (all p < 0.001), and Cronbach’s alpha (α) for variables made up of three or more items. This table reports the total number of participants who received each question. Due to the presence of missing values on some measures, the number of participants included in the regression models was N = 716 for COVID-19 and N = 706 for PFAS.
