瑜伽干预可以减轻压力，但其机制在很大程度上仍不清楚。了解瑜伽的工作原理对于优化干预至关重要。本研究测试了五种潜在的心理社会机制（增加正念，内感受意识，精神健康，自我同情和自我控制），这些机制被提出来解释瑜伽对压力的影响。42名参与者（62%女性; 64%白色）在瑜伽减压计划中完成了基线（T1）、干预中期（T2）和干预后（12周; T3）的调查。我们测量了感知的整体压力和压力反应。采用配对t检验评估变化;在残留变化模型中检验机制变化之间的关联。平均而言，从T1到T3，只有应激反应性降低。除自我同情外，所有心理社会机制从T1到T3都有所增加，从T2到T3变化最小。除了自我控制，每种机制的增加与T1和T2之间的压力测量值的降低以及T1到T3之间的整体压力感知降低密切相关（所有p <0.05）。针对这些资源的瑜伽干预可能会显示出更强的减压效果。未来的研究应使用积极的比较组和更大的样本更严格地测试这些联系。
Yoga interventions can reduce stress, but the mechanisms remain largely unidentified. Understanding how yoga works is essential to optimizing interventions. The present study tested five potential psychosocial mechanisms (increased mindfulness, interoceptive awareness, spiritual well-being, self-compassion, and self-control) that have been proposed to explain yoga’s impact on stress. Forty-two participants (62% female; 64% White) in a yoga program for stress reduction completed surveys at baseline (T1), mid-intervention (T2), and post-intervention (12 weeks; T3). We measured both perceived global stress and stress reactivity. Changes were assessed with paired t-tests; associations between changes in mechanisms were tested in residual change models. Only stress reactivity decreased, on average, from T1 to T3. Except for self-compassion, all psychosocial mechanisms increased from T1 to T3, with minimal changes from T2 to T3. Except for self-control, increases in each mechanism were strongly associated with decreases in both measures of stress between T1 and T2 and decreases in perceived global stress from T1 to T3 (all p’s<.05) Increased psychosocial resources are associated with stress reduction. Yoga interventions targeting these resources may show stronger stress reduction effects. Future research should test these linkages more rigorously using active comparison groups and larger samples.
