Subclaims¶

q3 i2 Across 24 studies of school-based mindfulness interventions, the weighted mean between-group effect size was Hedges's g = 0.40 and the within-group effect size was g = 0.41 (p < 0.0001). → Charlotte Zenner 2014

q3 · i2 · quant-synthesis · r3

Quantitative synthesis (inverse variance random-effects model) of 24 studies of school-based mindfulness interventions, 1348 students instructed in mindfulness and 876 controls. The review reports "Overall effect sizes were Hedge' s g = 0.40 between groups and g = 0.41 within groups ( p < 0.0001)" — a small-to-medium pooled effect.

"Overall effect sizes were Hedge' s g = 0.40 between groups and g = 0.41 within groups ( p < 0.0001)."

Related Claims¶

• The evidence base for school mindfulness interventions is promising but too variable for definitive practice recommendations — the general claim this finding bears on, with the studies behind it
• School-based mindfulness interventions produce small-to-moderate significant pre-post improvements in youth mental health and well-being compared to control groups — related
