q3 i? Egger's tests showed publication bias for Negative Behaviour and Anxiety/Stress among all 33 RCTs, and for the Mindfulness category among the 17 active-control RCTs. → Dunning 2019

q3 · i? · quant-synthesis · r3

Begg's funnel plots and Egger's regressions conducted for each meta-analysis. The review reports "publication bias was evident for Negative Behaviour and Anxiety/Stress" and, in active-control analyses, "in the Mindfulness category only."

"For all 33 RCTs, Egger’s tests showed that publication bias was evident for Negative Behaviour and Anxiety/Stress (Table 1). For the 17 RCTs with active control groups there was evidence of publication bias in the Mindfulness category only (Table 2)."

Discussion¶

Related Claims¶

• 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
• 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
• Risk of bias moderates the Mindfulness effect in active-control RCTs, with higher-risk studies producing larger effect sizes — related
• School-based mindfulness interventions produce small-to-moderate significant pre-post improvements in youth mental health and well-being compared to control groups — related
• Funnel-plot asymmetry was significant in both meta-analyses, indicating possible publication or selection bias — related
• The meta-analysis finds no major publication bias in the teacher personality–outcome associations — related
• Funnel-plot asymmetry ran contrary to small-study effects because larger-sample studies reported larger effect sizes, likely reflecting longer training programs — related
• Publication bias is present in the embodied vocabulary learning literature, suggesting pooled effects may overestimate the true benefit — related
• Total training hours significantly moderate MBI effects on negative behaviour across all RCTs, with more hours associated with larger reductions — related
• No publication bias is detected in the collected Covid-19 achievement estimates — related
• Publication bias is indicated for the performance-approach and performance-avoidance anxiety effects but not for the depression effects — related
• Funnel-plot asymmetry indicates small-study effects for some emotion–learning models — related
• Publication bias was significant for the overall DT analysis but not for the fluency, flexibility, or originality indicator analyses — related
• No evidence of publication bias was found in the achievement goal–dishonesty literature — related
