Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? MBIs are a promising approach for supporting students, but implementation varies widely (e.g., program length) and the child/youth evidence base is not developed enough for definitive recommendations about specific practices, citing Renshaw et al. (2017), Felver et al. (2016), and Zenner et al. (2014). → Browning 2020

q2 · i? · review · r2
Narrative review statement in the brief's universal supports section. It notes that common MBI practices include deep breathing, body-centered awareness, mindful movement, pausing before speaking, compassion practice, and guided relaxation, but that "there is, however, a lot of variability in implementation of MBIs, such as in terms of program length."
"The evidence base for MBIs with children and youths is not developed enough to provide definitive recommendations about specific practices within mindfulness approaches and programs."
Studies bearing on this claim¶
Do school and youth mindfulness programmes improve students' regulation, wellbeing and academic outcomes? This table gathers the studies behind this claim and the 15 narrower claims that bear on it: 7 distinct studies (3 quant-synthesis, 2 review, 1 design, 1 causal), q1–q3, 3 of 7 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
Discussion¶
Related Claims¶
- Implementation of co-regulation strategies was shaped by classroom context, facilitator experience and mindset, and varied in ease across strategies — related
- Social-emotional learning benefits persist at follow-up — related
- Drawing promising practices from program evaluations and extant character-development studies is challenging — a broader claim this one bears on
- Across all RCTs, mindfulness-based interventions significantly improve mindfulness, executive functioning, attention, depression, anxiety/stress and negative behaviours in youth, with small effect sizes — related
- Mindfulness and yoga interventions improved self-regulation in 4 of 8 interventions (50%), mostly applied within the adolescent age group. — related
- School-based mindfulness interventions show overall effect sizes of g = 0.40 between groups and g = 0.41 within groups — related
- Mindfulness practices are linked to academic improvements including reduced test anxiety, focus, and reading competence — a narrower finding that bears on this claim
- Mindfulness interventions consisting of combinations of various mindfulness activities show the largest effects on youth mental health and well-being — related
- Individual differences and program characteristics impact receptivity and effectiveness of school-based mindfulness training — a narrower finding that bears on this claim
- Effects of school-based mindfulness interventions differ according to whether delivery is by an outside facilitator or by trained educators/teachers — related
- The evidence base for school mindfulness interventions is heterogeneous and many studies are underpowered — related
- When only RCTs with active control groups are analysed, MBI benefits are restricted to Mindfulness (d = .42), Depression (d = .47) and Anxiety/Stress (d = .18) — a narrower finding that bears on this claim
- Mindfulness interventions in schools show the largest between-group effects for cognitive performance (g = 0.80) and smaller significant effects for stress (g = 0.39) and resilience (g = 0.36) — a narrower finding that bears on this claim
- Mindfulness interventions delivered during late adolescence (15–18) show the largest effects on youth mental health and well-being outcomes — a narrower finding that bears on this claim
- Mindfulness practices are linked to positive school climate outcomes including compassion, well-being, and self-regulation — a narrower finding that bears on this claim
- Students who learned mindfulness-based conflict resolution strategies used them outside school with siblings and friends — a narrower finding that bears on this claim
