Meta-analytical review of teacher burnout across 36 societies: the role of national learning assessments and gender egalitarianism.

Teacher burnout has hardly been compared across countries, although it has become a global health issue. This review aimed to examine teacher burnout (effect size) and its variation across countries by testing the effects of gender, gender egalitarianism, and national learning assessments (NLAs). A systematic literature search was carried out using keywords. In all, 156 studies from 36 countries were included that used quantitative methodology. Meta-analytical procedures were used to estimate effect sizes of three dimensions of burnout. Two-level multilevel mixed-effect model tested moderator variables at the country level. The overall effect size found for emotional exhaustion was 38.29 (95% CI = 35.26, 41.32), 29.45 (95% CI = 25.91, 32.99) for cynicism, and 68.75 (95% CI = 65.63, 71.87) for personal accomplishment, with significant differences across countries. Gender was negatively significant for personal accomplishment. Significant linear, curvilinear and interaction effects of NLAs and gender egalitarianism explained variations in burnout. Whereas more NLAs tends to increase burnout, more gender egalitarianism tends to decrease it, although this effect is not linear. Teacher burnout, as a health issue, varies significantly across countries suggesting that programmes to prevent this problem should consider environmental (educational system) and cultural conditions for a greater impact.
