The current study examined the association of OCD symptoms and OCD belief domains, for individuals engaged in Technology Supported Mindfulness training (TSM) using an EEG-based biofeedback device (called "Muse") that permits individuals to engage in home based mindfulness meditation practices. In this randomized controlled study, treatment-seeking 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) wait list control. At weeks 1, 4, and 8, participants completed self-report measures of OCD symptoms (YBOCS: Yale-Brown Obsessive Compulsive Scale) and OCD beliefs (OBQ; OCCWG, 2005). Latent Difference Score (LDS) models indicated that there was no significant longitudinal relationship between OBQ "Responsibility/Threat" (OBQ R/T) scores and OCD symptoms. The analysis of OBQ "Perfectionism/Certainty" (OBQ P/C) and OCD symptoms demonstrated a significant reciprocal relationship between these two variables, in which OCD symptoms predicted subsequent increases in OBQ P/C and vice versa. The analysis of OBQ "Importance/Control of Thoughts" (OBQ I/C) and OCD symptoms demonstrated a significant reciprocal relationship between these two variables, in which OCD symptoms predicted subsequent increases in OBQ I/C and vice versa. The analysis of OBQ domains and EEG derived attentional changes demonstrated a significant association between OBQ P/C and Alpha band frequencies. These results clarify the association of OBQ belief domains, OCD symptom change and EEG derived indicators of attention during TSM.
本研究考察了 OCD 症状和 OCD 信念领域与使用基于 EEG 的生物反馈设备（称为“Muse”）进行技术支持的正念训练（TSM）的个体之间的关联，该设备允许个体进行家庭正念冥想练习。在这项随机对照研究中，寻求治疗的患有主要 DSM-5 强迫症诊断的参与者（N=71）被随机分配到八周的：1）包含每日使用“Muse”设备的冥想计划，或 2）候补名单控制。在第 1、4 和 8 周，参与者完成了 OCD 症状的自我报告测量（YBOCS：耶鲁-布朗强迫症量表）和 OCD 信念的自我报告测量（OBQ；OCCWG，2005）。潜在差异得分（LDS）模型表明，OBQ“责任/威胁”（OBQ R/T）得分与 OCD 症状之间没有显著的纵向关系。对 OBQ“完美主义/确定性”（OBQ P/C）和 OCD 症状的分析表明，这两个变量之间存在显著的相互关系，其中 OCD 症状预测 OBQ P/C 的后续增加，反之亦然。对 OBQ“思想的重要性/控制”（OBQ I/C）和 OCD 症状的分析表明，这两个变量之间存在显著的相互关系，其中 OCD 症状预测 OBQ I/C 的后续增加，反之亦然。对 OBQ 领域和 EEG 衍生注意力变化的分析表明，OBQ P/C 和 Alpha 波段频率之间存在显著关联。这些结果阐明了在 TSM 期间，OBQ 信念领域、OCD 症状变化和 EEG 衍生注意力指标之间的关联。
