An Analysis of the Impact of Digital Therapeutic Interventions on Attention and Working Memory in Children with Attention-Deficit/Hyperactivity Disorder: A Randomized Controlled Trial

Previous research has investigated non-pharmacological digital therapeutic interventions to improve compliance and reduce side effects in attention-deficit/hyperactivity disorder (ADHD) medication treatments for children. This study focuses on validating the effects of game-based intervention content for enhancing working memory and concentration. It tracks quantitative changes to evaluate improvements in concentration and working memory when digital game-based content is used as adjunct therapy alongside medication for children with ADHD. Thirty children participated; one group received digital therapeutic intervention based on game content alongside medication (experimental) and the other group received conventional treatments (control). The study results show that children with ADHD in the experimental group, who use digital game-based content, exhibit a reduction of 8.13 ± 6.71 points in the K-ARS total score at the fourth week compared to baseline, while the control group shows a reduction of 7.14 ± 8.73 points. Inattention decreases by 36.84% in the experimental group and 28.56% in the control group, while hyperactivity–impulsivity decreases by 50.71% in the experimental group and 34.00% in the control group. All the results are analyzed using a paired t-test between baseline and the fourth week. Significant decreases in the K-CBCL total problem behavior score and internalizing and externalizing behaviors are consistently observed at 28 days compared with baseline. The FAIR attention–concentration test results show significant differences between the experimental and control groups in the Q-percentile and Q-standard scores, with repeated measures ANOVA results showing p = 0.006 and p = 0.007, respectively. Digital content was shown to influence digital therapeutic intervention—a non-pharmacological treatment for ADHD.
