Note. Cells contain age and sex-adjusted means of changes in each MBI subscale. Abbreviations: MBI = Maslach Burnout Inventory; EE = emotional exhaustion; DEP = depersonalisation; PPA = poor personal accomplishment.

^⁎Significant change in the subscale over time.

^ap value of contrasts assessing differences between groups based on job title.

^bp value of contrasts assessing differences between groups based on having MBI levels below or above the median before COVID-19.
