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.
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.
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.
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.
本研究考察了基于活动的正念疗法对 11 至 17 岁 ADHD 青少年的注意力脑电图（EEG）指数的影响，与候补对照组相比。
在治疗前和治疗后，参与者完成单点焦点休息任务和两个主动注意任务时记录 EEG。在每个任务中计算θ功率、β功率和θ/β 比（TBR）。
发现组间时间任务的显著交互作用表明，治疗组的注意力能力显著改善，表现为 TBR 降低，而对照组则没有。
研究结果支持正念疗法对提高 ADHD 青少年注意力控制的益处，并通过提供这些收益在神经水平上的证据扩展了文献。研究结果还为在 ADHD 青少年中检查正念相关注意力收益时使用主动注意任务提供了方法学支持。讨论了未来的研究方向。
