Mindfulness training (MT) programs represent an approach to attention training with well-validated mental health benefits. However, research supporting MT efficacy is based predominantly on weekly-meeting, facilitator-led, group-intervention formats. It is unknown whether participants might benefit from neurofeedback-assisted, technology-supported MT (N-tsMT), in which meditation is delivered individually, without the need for a facilitator, travel to a training site, or the presence of a supportive group environment. Mirroring the validation of group MT interventions, the first step in addressing this question requires identifying whether N-tsMT promotes measurable benefits. Here, we report on an initial investigation of a commercial N-tsMT system.
In a randomized, active control trial, community-dwelling healthy adult participants carried out 6 weeks of daily practice, receiving either N-tsMT (n = 13), or a control condition of daily online math training (n = 13). Training effects were assessed on target measures of attention and well-being. Participants also completed daily post-training surveys assessing effects on mood, body awareness, calm, effort, and stress.
Analysis revealed training effects specific to N-tsMT, with attentional improvements in overall reaction time on a Stroop task, and well-being improvements via reduced somatic symptoms on the Brief Symptom Inventory. Attention and well-being improvements were correlated, and effects were greatest for the most neurotic participants. However, secondary, exploratory measures of attention and well-being did not show training-specific effects. N-tsMT was associated with greater body awareness and calm, and initially greater effort that later converged with effort in the control condition.
Preliminary findings indicate that N-tsMT promotes modest benefits for attention and subjective well-being in a healthy community sample relative to an active control condition. However, the findings would benefit from replication in a larger sample, and more intensive practice or more comprehensive MT instruction might be required to promote the broader benefits typically reported in group format, facilitated MT.

正念训练(MT)课程代表了一种经过充分验证的具有心理健康益处的注意力训练方法。然而,支持 MT 功效的研究主要基于每周一次的会议、由主持人领导的小组干预形式。目前还不清楚参与者是否会从神经反馈辅助的、基于技术的正念训练(N-tsMT)中受益,在这种训练中,冥想是个体进行的,不需要主持人、前往培训地点或有支持性的小组环境。为了验证小组 MT 干预的有效性,解决这个问题的第一步需要确定 N-tsMT 是否能带来可衡量的益处。在这里,我们报告了一项商业 N-tsMT 系统的初步研究结果。
在一项随机、活性对照试验中,社区居住的健康成年参与者进行了为期 6 周的日常练习,接受 N-tsMT(n=13)或每日在线数学训练的对照条件(n=13)。使用注意力和幸福感的目标测量来评估训练效果。参与者还完成了每日训练后调查,评估对情绪、身体意识、平静、努力和压力的影响。
分析显示,N-tsMT 具有特定的训练效果,在 Stroop 任务中的整体反应时间上注意力有所提高,在 Brief Symptom Inventory 上的躯体症状减少表明幸福感得到了改善。注意力和幸福感的改善呈正相关,效果对最神经质的参与者最大。然而,对注意力和幸福感的次要、探索性测量没有显示出特定于训练的效果。N-tsMT 与更高的身体意识和平静相关,最初的努力更大,但后来与对照组的努力趋同。
初步结果表明,与活性对照条件相比,N-tsMT 对健康社区样本的注意力和主观幸福感有适度的促进作用。然而,这些发现需要在更大的样本中得到复制,并且可能需要更密集的练习或更全面的 MT 指导,以促进通常在小组形式、有主持人的 MT 中报告的更广泛的益处。
