这项随机对照试验在一组报告高水平慢性压力的成人样本中检测了正念对非快感症状的影响。冥想天真的成年人(N=68，MAGE=32，62%女性)被随机分为基于8周组的MBSR干预(N=35)和等待名单对照组(N=33)。我们假设，专注力的变化将在状态和非享乐症状变化之间的关系中起中介作用。此外，本研究旨在确定是否有其他理论上相关的机制(即，压力、负面影响、抑郁)参与了无快感症状的变化。本研究结果为MBSR对社会性快感缺乏的影响通过其正念的基本机制进行全面的中介提供了证据。这些结果突出了MBSR所针对的非快感症状的特异性，社交快感缺失症状被正念的变化所改变，而其他非快感领域则不是。对社会性快感缺乏领域的影响的特异性可能部分是由于MBSR的基于群体的性质。此外，尽管压力、抑郁、NA和非享乐性症状存在关联关系，但没有出现中介关系。应根据研究局限性对此处提出的结果进行评估，例如对自我报告措施的依赖以及缺乏关于文化或地理多样性的信息。
This randomized controlled trial examined the effects of mindfulness on anhedonic symptoms in a sample of adults reporting high levels of chronic stress. Meditation-naive adults (N = 68, Mage = 32, 62% female) were randomized to either an 8-week group-based MBSR intervention (N = 35), or a waitlist control group (N = 33). We hypothesized that changes in mindfulness would mediate the relationship between condition and changes in anhedonic symptoms. Additionally, the present study aimed to determine if other theoretically linked mechanisms (i.e., stress, negative affect [NA], depression) were involved in producing changes in anhedonic symptoms. Results provided evidence for full mediation of the effect of MBSR on social anhedonia through its essential mechanism of & UDelta;Mindfulness. These results highlight specificity of anhedonic symptoms targeted by MBSR, with social anhedonia symptoms being modified by changes in mindfulness whereas other anhedonic domains were not. The specificity of effects to the social anhedonia domain may be in part due to the group-based nature of MBSR. Additionally, although associative relationships were present for stress, depression, NA, and anhedonic symptoms, no mediational relationships emerged. Results presented here should be evaluated in light of study limitations, such as the reliance on self-report measures as well as a lack of information regarding cultural or geographic diversity.
