Mindfulness meditation is a means of increasing awareness of the present moment. Mindfulness Mediation Interventions (MMI) positively impact psychological functioning, yet the neurocognitive mechanisms that mediate these effects have been less well-defined. Here, the primary aim was to evaluate whether the effects of a 10-week MMI were mediated by changes in attention and creativity performance, as well as resting-state theta/beta (TB) ratio and alpha power. We also sought to determine whether any of these measures at baseline were predictive of mindfulness success, as rated by the 7-11-year-old participants and their teachers. Reductions in depression from pre-to-post were mediated by reductions in TB ratio and increases in alpha power; however, they were not mediated by attention/creativity changes. Higher baseline attention and creativity scores predicted enhanced mindfulness success post-intervention but notably, follow-up analyses revealed that those scoring lower on these measures were more likely to have reduced depression from pre-to-post.
正念冥想是一种增强当下意识的方式。正念冥想干预（MMI）对心理功能有积极影响，但其介导这些效应的神经认知机制尚未得到很好的界定。在此，主要目的是评估为期10周的MMI的效果是否由注意力和创造力表现的变化以及静息态θ/β（TB）比值和α波功率介导。我们还试图确定基线时的这些测量指标是否能预测正念的成功，这由7至11岁的参与者及其教师进行评分。从干预前到干预后抑郁的减轻是由TB比值的降低和α波功率的增加介导的；然而，它们并非由注意力/创造力的变化介导。较高的基线注意力和创造力得分预测干预后正念的成功增强，但值得注意的是，后续分析显示，在这些测量指标上得分较低的人从干预前到干预后抑郁更有可能减轻。
