Metaanalyse zur Wirksamkeit achtsamkeitsbasierter Interventionen bei ADHS im Kindes- und Jugendalter
Abstract
Zusammenfassung. Die vorliegende Metaanalyse berechnet die Wirksamkeit achtsamkeitsbasierter Interventionen bei Kindern und Jugendlichen mit ADHS gemäß empirischer Studien aus den Jahren 2008 – 2018. Als abhängige Maße werden die ADHS-Symptomatik, kognitive Leistungen (Aufmerksamkeitsleistungen in standardisierten Tests) sowie ADHS-spezifische Komorbiditäten berücksichtigt. Insgesamt wurden 16 Studien einbezogen. Im Ergebnis zeigt sich hinsichtlich der Reduktion der gesamten ADHS-Symptomatik eine große Effektstärke von d = 1.08. Zudem konnten eine Verringerung der Unaufmerksamkeitssymptomatik (d = 0.47), mittlere Effekte auf Hyperaktivität / Impulsivität sowie moderate bis große Effekte auf komorbide internalisierende Störungen (Depressionen, Angststörungen) festgestellt werden. Die Metaanalyse liefert Hinweise darauf, dass achtsamkeitsbasierte Interventionen bei Kindern und Jugendlichen mit ADHS wirksam sind. Jedoch bestehen auf Ebene der Einzelstudien beträchtliche methodische Limitationen.
Abstract. A rising number of clinical and school-related empirical studies report a good efficacy of mindfulness-based interventions relating to attention deficit hyperactivity disorder (ADHD) symptom reduction. However, no systematic meta-analysis has been performed to synthesize the findings of school-related and clinical studies in the period 2008 – 2018. The current meta-analysis considers the impact of mindfulness-based interventions on ADHD symptomatology, cognitive functioning (inattention in standardized tests), and ADHD-specific comorbidities (anxiety, depression, and dissocial behavior). Studies from the Psychology and Behavioral Science Collection, Psyndex, PsycINFO, and Google Scholar were taken into account. The effect size analysis of randomized controlled trials (RCTs) was based on Klauer’s averaged and weighted effect size, which also controls pretest differences between experimental groups and controls. Studies measuring dependent variables before and after mindfulness-based interventions were also included using weighted Cohen’s d effect sizes. As a result, 16 studies met the inclusion criteria. Based on five experimental studies, an ADHD total symptom reduction was found when comparing both the pretest–posttest measurements of the ADHD groups (1.02) and the differences between experimental groups and controls (1.08). Eight studies found reduced inattention symptoms amounting to an average effect size of 0.47 (pre–post), while in three experimental studies the average effect was 0.32. Pretest–posttest improvements of accuracy (0.45) and reaction speed (0.83) in standardized attention tests were reported. These effects were also shown in five experimental studies. Some studies found moderate and middle effects relating to hyperactivity/impulsiveness symptoms. ADHD comorbidities such as depressive (0.41 pretest–posttest, 0.29 RCT) and anxiety symptoms (0.48 pretest–posttest, 0.38 RCT) were significantly reduced. In six studies with pretest–posttest measurements, a large effect on dissocial behavior was reported (1.00), whereas this effect was not evident in three RCTs that considered dissocial ADHD comorbidities (0.23). In the overall picture, indications were found of a medium-to-good efficacy of mindfulness-based interventions on ADHD, but the results can only be generalized to a limited extent owing to the small number of methodologically sufficiently good studies and the inhomogeneity of the effects. With regard to inattentiveness, there are indications of a marked variance in the ADHD self-assessment scales. This implies the necessity to consider multiple diagnostic sources of information when recording attention processes. Further studies representative of the ADHD population, especially experimental studies, are required, which also consider implementation aspects and differential effects (e. g., different effects of individual therapy components). The possibly high relevance of mindfulness competence for subjective well-being and thus the quality of life of children and adolescents with ADHD could be further investigated with prospective longitudinal studies.
