  1. Note. The correlation of repeated measurements within the individual (the personal ID level) is taken into account in the mixed model analyses. The clustering effect of workplaces/teams is taken into account by correcting for school location, by adding three dummy variables to the model
  2. * p-value < 0.05
  3. aThe regression coefficient indicates the difference between the intervention and the control group on average over time, corrected for baseline value of the particular outcome
  4. bAdjusted for age, gender, school location, and education level. The correlation of repeated measurements within the individual (the personal ID level) is taken into account in the mixed model analyses
  5. cMeasured for the first time at T1; regression coefficient is an unstandardized B
