  1. M mean, SD standard deviation
  2. Analysis for obtaining M, SD and correlations for the total population (21 countries) was conducted by IEA IDB Analyzer; parentheses include the respective range across countries. Standardized factor loadings obtained by Mplus analyses (all p < 0.001). Sampling weights have been used
