Meta-analysis of National Research on the Effectiveness of Neuropsychological Interventions on Executive Functions

The objective of this meta-analysis was to compile the studies conducted on the efficacy of neuropsychological interventions with respect to executive functions. Full-text articles, dissertations, and research projects that were published in Iran between 2010 and 2020 in quarterly journals, scientific research journals, and scientific information databases affiliated with the University Jahad, the Computer Research Center for Islamic Sciences, and the Private site of Iran Magazines Bank constituted the study population. A total of 131 effect sizes were analyzed from the 126 derived studies after 71 were selected in accordance with the inclusion and exclusion criteria. Data were analyzed utilizing funnel plots, sensitivity analyses, fixed and random effects models, and heterogeneity analyses in conjunction with CMA2 software. The results indicated that neuropsychological interventions had a significant effect on executive functions, and according to Cohen’s criterion, the combined effect size for the random-effects model was substantial (ES = 1.22). The findings additionally indicated that, among the various classes examined, Attention Deficit Hyperactivity Disorder has the greatest effect size, and that, among executive functions, neuropsychological interventions exert the most significant influence on the working memory component. Consequently, it is recommended that clinicians and specialists employ neuropsychological interventions to enhance and improve the planning, attention, inhibition, and working memory capabilities of their clients.
