CONCLUSIONS: The ECogFun‑VR program produced selective cognitive gains, particularly in working‑memory manipulation, but did not yield significant changes in higher‑order functional outcomes over 12 weeks. Findings suggest that planning and organization skills may require longer dosage, increased intensity, or enhanced generalization supports to achieve measurable functional change. VR‑supported EF interventions remain a promising avenue for targeted skill development in youth with ADHD.
