Measures from wearable devices could be a valuable supplement to mindfulness assessment and intervention. This observational study evaluated measures from a consumer-grade EEG headband (Muse, InteraXon, Inc.) as novel correlates of state mindfulness during focused attention meditation.
Adult participants (N = 68, M = 22.66, SD = 7.35) completed a task-based measure of state mindfulness and thought probe measures of subjective mind wandering while meditating with the EEG headband. A subset completed 14 days of home practice (n = 29).
Device measures were sensitive to attention lapses within-participants in the state mindfulness task (d = 0.56) and had large between-participants associations for the same task (r = -0.50). Mean device metrics from home practice together explained approximately 30% of variance in self-reported trait mindfulness, attentional control, nonattachment, and decentering.
EEG biomarkers show potential as correlates of mindfulness with distinct benefits over existing assessment methods.
可穿戴设备的测量数据可能是正念评估和干预的重要补充。这项观察性研究评估了一款消费级脑电图头带（Muse，InteraXon公司）的测量数据，将其作为专注注意力冥想期间状态正念的新相关指标。
成年参与者（N = 68，M = 22.66，SD = 7.35）在使用脑电图头带冥想时，完成了一项基于任务的状态正念测量以及主观思维游移的思维探测测量。其中一部分参与者（n = 29）完成了为期14天的家庭练习。
在状态正念任务中，设备测量数据对参与者内部的注意力 lapses 敏感（d = 0.56），并且在同一任务中参与者之间的关联很大（r = -0.50）。家庭练习中的平均设备指标共同解释了自我报告的特质正念、注意力控制、无执着和去中心化中约30%的方差。
脑电图生物标志物显示出作为正念相关指标的潜力，与现有评估方法相比具有明显优势。
