q3 i? Across all 33 RCTs, total hours of mindfulness training significantly moderated reduction in Negative Behaviour (Q = 7.30, p = .007), with larger effect sizes related to more hours of training. → Dunning 2019

Random effects meta-regression across all 33 RCTs testing dose (total training hours) as a moderator. The review reports dose "was a significant moderator of a reduction in Negative Behaviour"; no effect size is printed for the moderation.

"total training hours was a significant moderator of a reduction in Negative Behaviour ( Q = 7.30, p = .007), with larger effect sizes related to more hours of training."

Discussion¶

Related Claims¶

• 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
• 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) — related
• Effect sizes vary by control group type, with wait-list controls yielding the largest mean effect and no-contact controls the smallest — related
• Publication bias is evident for Negative Behaviour and Anxiety/Stress across all RCTs and for Mindfulness in active-control RCTs, suggesting overestimation of MBI effects — related
