This meta -analysis examines the efficacy of the cognitive behavioral approach to interventions toward the improvement of executive function for children/ adolescents with high -functioning autism spectrum disorder (HF-ASD). This meta -analysis paper has identified ten studies involving 437 participants with high -functioning autism spectrum disorder aged between 5 and 18. All the participants reported IQs were at or above 70. A random effect meta -analysis yielded a moderately significant effect (Hedge g = 0.72) with significant heterogeneity [Q(10) = 228.36, p < .001]. There were considerable variations in the executive function domain, i.e., working memory (hedge g = 1.23) and inhibition (g = 0.47), showing significant treatment effects. On the other hand, cognitive flexibility (g = -0.51) and planning (g = -0.07) show non -significant effects toward cognitive behavioral interventions. The finding suggests that the cognitive behavioral approach to intervention demonstrates efficacy in improving executive function in children or adolescents with high -functioning autism spectrum disorder. All the cognitive behavioral intervention studies were conducted in developed countries, so differences between the approaches between developed and developing countries were inconclusive. Future studies are needed to investigate the effectiveness of cognitive behavioral techniques in intervention for low -functioning autism spectrum disorder children.
