The levels of perceived stress were measured with the widely used Perceived Stress Scale (PSS; Cohen et al., 1983; Cohen & Williamson, 1988). It includes 10 items (four reverse‐scored) concerning various subjective feelings related to problems, behaviours, and ways of coping, on a 5‐point scale from 0 (never) to 4 (very often). Cronbach’s alphas for each of the language versions of the scale are presented in the Supplementary Material (https://osf.io/cznr8/).
