  1. Mean scores with 95% confidence intervals at three time points.
  2. * p < 0.05, ** p < 0.01
  3. The p-values are based on non-parametric tests for related samples between T0 and T1, and T1 and T2.
  4. a: Intervention group, b: Control group
  5. T0: Immediately before the intervention period started, T1: Immediately after the intervention period ended, T2: Six months after the intervention period ended
  6. IG: Intervention group, CG: Control group
