背景和目标：最近有大量研究评估正念作为临床干预措施的功效。然而，人们对特质正念或特质正念如何与适应不良的情绪调节策略相互作用仍然知之甚少。目前的研究进一步探讨了特质正念对情绪调节的影响，以及特质正念的特定因素是否与对压力的主观和自主反应唯一相关。方法：48 名健康男性参与者接受了使用抑制策略的培训，然后指示他们抑制他们对吸入 15% CO2 的空气混合物的反应 90 秒，同时记录他们的主观痛苦和心率。结果：在控制焦虑相关变量后，提供对观察到的经历的描述预示着心率对二氧化碳吸入的反应会降低，而将注意力限制在当前时刻的技巧则独特地预示着主观痛苦的减少。关注身体或感官刺激的倾向预示着吸入二氧化碳期间会出现更大的痛苦。 局限性：仅纳入健康男性限制了研究结果的普遍性。此外，样本量相对较小。结论：这些研究结果表明，与特质正念相关的因素可以预测较少的压力反应和痛苦，同时抑制的程度高于已被证明可以预测焦虑反应的其他变量。讨论了对情感和临床研究的影响。 (C) 2013 Elsevier Ltd. 保留所有权利。
Background and objectives: There has been a recent proliferation of research evaluating the efficacy of mindfulness as a clinical intervention. However, there is still little known about trait mindfulness, or how trait mindfulness interacts with maladaptive emotion regulation strategies. The current study further explores the effect of trait mindfulness on emotion regulation, as well as whether specific factors of trait mindfulness are uniquely associated with subjective and autonomic reactivity to stress.Methods: Forty-eight healthy male participants were trained in the use of the suppression strategy and then instructed to suppress their responses to the inhalation of a 15% CO2-enriched air mixture for 90 s while their subjective distress and heart rate were recorded.Results: After controlling for anxiety-related variables, the ability to provide descriptions of observed experiences predicted less heart rate reactivity to CO2 inhalation, while skillfulness at restricting attention to the present moment was uniquely predictive of less subjective distress. The tendency to attend to bodily or sensory stimuli predicted greater distress during CO2 inhalation.Limitations: The inclusion of only healthy males limits the generalizability of study findings. Also, the sample size was relatively small.Conclusions: These findings suggest that factors associated with trait mindfulness predict less stress reactivity and distress while engaging in suppression above and beyond other variables that have been shown to predict anxious responding. The implications for emotion and clinical research are discussed. (C) 2013 Elsevier Ltd. All rights reserved.
