Abstract

Background: The efficacy of meditation-based therapies for attention deficit/hyperactivity disorder (ADHD) across the lifespan remains uncertain. Objective: To conduct a systematic review and meta-analysis of randomised controlled trials (RCTs) assessing the efficacy of meditation-based therapies for ADHD core symptoms and associated neuropsychological dysfunctions in children/adolescents or adults with ADHD. Methods: We searched Pubmed, PsycInfo, Embase+Embase Classic, Ovid Medline and Web of Knowledge with no language, date or type of document restriction, up to 5 May 2018. Random-effects model was used. Heterogeneity was assessed with Cochran’s Q and I 2 statistics. Publication (small studies) bias was assessed with funnel plots and the Egger’s test. Studies were evaluated with the Cochrane risk of bias (RoB) tool. Analyses were conducted using Comprehensive Meta-Analysis. Findings: 13 RCTs (seven in children/adolescents, n=270 and six in adults, n=339) were retained. Only one RCT was double-blind.Meditation-based therapies were significantly more efficacious than the control conditions in decreasing the severity of ADHD core symptoms (inattention+hyperactivity/impulsivity: children/adolescents: Hedge’s g=-0.44, 95% CI −0.69 to −0.19, I 2 0%; adults: Hedge’s g=−0.66, 95% CI –1.21 to −0.11, I 2 81.81%). No significant effects were found on neuropsychological measures of inattention and inhibition in children/adolescents. In adults, significant effects were detected on working memory and inhibition, although these results were based on a small number of studies (n=3). 57% and 43% of the studies in children/adolescents were rated at overall unclear and high risk of bias, respectively. In adults, 33% and 67% of the studies were deemed at overall unclear and high risk of bias, respectively. No evidence of publication bias was found. Conclusions: Despite statistically significant effects on ADHD combined core symptoms, due to paucity of RCTs, heterogeneity across studies and lack of studies at low risk of bias, there is insufficient methodologically sound evidence to support meditation-based therapies for ADHD. Trial registration number: PROSPERO 2018 [CRD42018096156].

  • Half of the studies in the meditation-based therapy meta-analysis did not use active controls.

    “It found moderate reductions in ADHD symptoms in both children and adolescents (6 RCTs, 240 participants) and adults (6 RCTs, 339 participants), but half the studies did not use active controls.”
  • Meditation-based therapy was associated with moderate reductions in ADHD symptoms in children and adolescents.

    “It found moderate reductions in ADHD symptoms in both children and adolescents (6 RCTs, 240 participants) and adults (6 RCTs, 339 participants), but half the studies did not use active controls.”
  • Meditation-based therapy was associated with moderate reductions in ADHD symptoms in adults.

    “It found moderate reductions in ADHD symptoms in both children and adolescents (6 RCTs, 240 participants) and adults (6 RCTs, 339 participants), but half the studies did not use active controls.”
  • There is insufficient methodologically sound evidence to support recommending meditation-based therapies for targeting ADHD core symptoms or related neuropsychological dysfunctions in children, adolescents, or adults with ADHD.

    “The authors concluded “there is insufficient methodologically sound evidence to support the recommendation of meditation-based therapies as an intervention aimed to target ADHD core symptoms or related neuropsychological dysfunctions in children/adolescents or adults with ADHD” (Zhang et al., 2018).”
  • Removing studies with waiting list controls made the meditation-based therapy results nonsignificant.

    “Removing studies with waiting list controls made results nonsignificant.”

    From The World Federation of ADHD International Consensus Statement: 208 Evidence-based conclusions about the disorder (2021) · cites this paper as Zhang et al., 2018

    The Original article reports that results became nonsignificant after removing two studies whose interventions were not exclusively meditation-based, not after removing waiting-list-controlled studies. It reports that restricting analyses to waiting-list controls increased effect sizes, but our copy does not report results for an analysis excluding those studies. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
