  1. *We calculated scores with the RStudio packages ‘psych’ (ω) and ‘irr’ (κ). We included the reliability indices for α and ω in this table to indicate the scales’ internal consistency and ensure comparability with previous studies such as Klepsch and Seufert (2020), who only used ω for reporting the reliability. α = Cronbach’s alpha, κ = Cohen’s Kappa (Inter-Rater-Reliability), M = mean score, SD = standard deviation, ω = McDonald’s omega
