尽管理论表明正念和正念疗法与理解创伤、创伤后应激障碍（PTSD）和解离体验之间的关系有关，但很少有研究直接比较正念和创伤相关的痛苦与解离之间的关系，包括解离性创伤相关的意识改变状态（TRASC）。因此，我们研究了正念特质（五方面正念问卷[FFMQ]）是否部分介导了自我报告的创伤暴露之间的关系，无论是发生在童年时期还是生活中的任何时候，以及952名在线调查的创伤暴露参与者的PTSD，分离亚型PTSD和TRASC的结果。增加的创伤经历与PTSD，分离性PTSD和TRASC之间的关系部分由注意描述能力下降，意识行为和非判断特征介导，尽管注意非反应性下降仅部分介导儿童创伤暴露增加与PTSD症状之间的关联，而增加正念观察部分介导了终身创伤暴露增加与PTSD和分离症状增加之间的关联。我们的研究结果表明，特质正念不同方面的能力改变或降低可能是创伤暴露导致创伤相关痛苦和解离发展的一种机制。
Although theory suggests the relevance of mindfulness and mindfulness-based therapies for understanding relationships between trauma, posttraumatic stress disorder (PTSD), and dissociative experiences, little research has directly compared associations between mindfulness and trauma-related distress versus dissociation, including dissociative trauma-related altered states of consciousness (TRASC). We therefore examined whether mindfulness traits (Five Facet Mindfulness Questionnaire [FFMQ]) partially mediated the relationship between self-reported trauma exposure, whether occurring during childhood or anytime in life, and outcomes of PTSD, dissociative subtype PTSD, and TRASC in 952 trauma-exposed participants surveyed online. The relationships between increased traumatic experiences and PTSD, dissociative PTSD, and TRASC were partially mediated by the decreased capacity for mindful describing, acting with awareness, and non-judging traits, although decreased mindful non-reactivity partially mediated only the association between increased childhood trauma exposure and PTSD symptoms, while increased mindful observing partially mediated the association between increased lifetime trauma exposure and increased PTSD and dissociative symptoms. Our findings suggest that altered or decreased capacity for different facets of trait mindfulness may be one mechanism by which trauma exposure leads to the development of trauma-related distress and dissociation.
