ABSTRACT

Objective: This study systematically reviewed randomized controlled trials (RCTs) on executive function (EF) interventions in adults with attention deficit hyperactivity disorder (ADHD) to identify effective approaches.Methods: PubMed, Web of Science, and PsycINFO were searched for RCTs published between January 2015 and November 2024. The key search terms included “attention deficit hyperactivity disorder,” “executive function,” “randomized controlled trial,” “intervention,” “program,” and “training.” Thirteen studies were selected based on the predefined inclusion and exclusion criteria. Results: The 13 selected studies were analyzed for risk of bias, intervention approaches, duration, effectiveness, and assessment tools. Most studies had a “high” or “some concerns” risk of bias. Interventions are categorized into cognitive, activity-based, and physical approaches. Of these, cognitive approaches were the most common. All studies reported improvements in EF, particularly global EF, inhibition, and working memory. Several studies reported improvements in ADHD symptoms, psychosocial symptoms, quality of life, and occupational performance. Twelve different EF assessment tools were identified, with the Behavior Rating Inventory of Executive Function-Adult Version being the most frequently used.Conclusion: EF interventions in adults with ADHD demonstrated consistent benefits across various intervention approaches. These findings support the clinical value of EF interventions in adults with ADHD, and may be used to guide future research and interventions.
