Cognitive Behavior Therapy (CBT) incorporating Exposure with Response Prevention (ERP) is the most efficacious treatment intervention for Obsessive Compulsive Disorder (OCD); however, there is a growing literature indicating that mindfulness based approaches can be beneficial in terms of managing OCD symptoms. The current study examined the potential benefits of using a consumer grade EEG-based biofeedback device (called "Muse") that permits individuals to engage in mindfulness meditation practices while at home. In this randomized controlled study, participants with a principal DSM-5 diagnosis of OCD (N = 71) were randomly assigned to eight weeks of: 1) a meditation program involving daily use of the "Muse" device, or 2) waitlist control. At weeks 1, 4, and 8, participants completed a five minute "open monitoring" practice while EEG data was recorded, and they completed self-report measures of mindfulness (FFMQ: Five Factor Mindfulness Questionnaire) and OCD symptoms (YBOCS: Yale-Brown Obsessive Compulsive Scale). Latent Difference Score (LDS) models demonstrated that the FFMQ "Non-Reactivity" facet and EEG-derived correlates of "Mind Wandering" (i.e., alpha, beta, but not delta or theta band power) were temporally associated with subsequent changes in YBOCS symptom scores. Participants in the Muse group (in comparison to the control group) experienced increased FFMQ "Non-Reactivity" and decreased mind wandering (increased alpha and beta band power), and in each case, these variables were associated with subsequent OCD symptom improvement. These results suggest that technology supported mindfulness training for OCD is associated with improvements in OCD symptoms, mindfulness and decreased mind wandering.
认知行为疗法（CBT）结合暴露与反应阻止疗法（ERP）是强迫症（OCD）最有效的治疗干预方法；然而，越来越多的文献表明，基于正念的方法在管理强迫症症状方面可能有益。本研究考察了使用一种消费级基于脑电图的生物反馈设备（称为“缪斯”）的潜在益处，该设备允许个体在家中进行正念冥想练习。在这项随机对照研究中，主要根据《精神疾病诊断与统计手册》第5版诊断为强迫症的参与者（N = 71）被随机分配到以下两种情况之一，为期八周：1）一个冥想项目，包括每天使用“缪斯”设备；2）等待名单对照组。在第1、4和8周，参与者在记录脑电图数据的同时完成了五分钟的“开放监测”练习，并完成了正念（FFMQ：五因素正念问卷）和强迫症症状（YBOCS：耶鲁-布朗强迫症量表）的自我报告测量。潜在差异得分（LDS）模型表明，FFMQ的“非反应性”方面以及脑电图得出的“走神”相关指标（即阿尔法、贝塔波段，但不包括德尔塔或西塔波段功率）与随后YBOCS症状评分的变化在时间上相关。缪斯组的参与者（与对照组相比）FFMQ的“非反应性”增加，走神减少（阿尔法和贝塔波段功率增加），在每种情况下，这些变量都与随后强迫症症状的改善相关。这些结果表明，技术支持的强迫症正念训练与强迫症症状改善、正念增强和走神减少有关。
