Key findings A significant group by time by task interaction indicated that the mindfulness treatment group, but not the waitlist control group, showed improved attentional ability as indexed by decreased theta/beta ratio (TBR). The authors conclude that activity-based mindfulness may enhance attentional control in youth with ADHD and that these gains are evident at a neural level.

Abstract

Objective: The current study examined the impact of an activity-based mindfulness treatment on EEG indices of attention in youth with ADHD aged 11 to 17 years compared with a waitlist control group.

Method: Pre- and post-treatment, EEG was recorded as participants completed a single-point focus rest task and two active attention tasks. Theta power, beta power, and theta/beta ratio (TBR) were calculated during each task.

Results: A significant group by time by task interaction was found that indicated significant improvement in attentional ability, indexed by decreased TBR, for the treatment group but not controls.

Conclusion: Findings support the benefit of mindfulness treatment for enhancing attentional control in youth with ADHD and extend the literature by providing evidence of these gains at a neural level. Findings also offer methodological support for the use of active attention tasks when examining mindfulness-related attentional gains in youth with ADHD. Directions for future research are discussed.
